Description

Technical Field

[0001] The present invention relates to the technical field of window display priority of Linux operating systems, and in particular to a method, device, equipment and medium for authorizing window dominance display in a multi-screen mode. Background Art

[0002] The Linux operating system is used across various industries, and with the increasing diversification and intelligence of desktop environments, the demand for an interactive interface experience is becoming increasingly demanding. Important pop-up windows in the desktop environment require strong reminders and priority actions. For example, when an authorization pop-up window appears, other application interfaces cannot be operated. This includes, but is not limited to, disabling the taskbar, desktop, control panel, and file manager. This ensures timely authorization and ensures the operation of important functions.

[0003] Existing technologies often mask the full-screen window by displaying a top-level, transparent window, and then displaying a sub-window on top of the full-screen window, restricting the user to operations within the full-screen window. This ensures the priority of the window. However, when authorization pop-up windows are required, especially in multi-screen scenarios, users can perform activities other than authorized operations on other screens that are not masked, affecting the priority of the authorization window, resulting in the inability to obtain authorization in a timely manner and the inability to ensure the operation of important functions.

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0052] In the Linux operating system, users can continue to click, input, and switch interfaces in other general program windows through areas not covered by the authorization window. This can easily cause the authorization window to be ignored, affecting the timeliness of authorization and delaying the use of important functions. Covering the screen with a full-screen window can prevent users from clicking outside the authorization window. However, in a multi-screen environment, the full-screen window often has difficulty covering all screens as the number of screens changes. Users can still operate on other screens, making it impossible to ensure the high priority of the authorization window, which affects authorization efficiency.

[0053] Example 1

[0054] Figure 1 This is a flowchart of a method for displaying an authorized window in a multi-screen mode according to a first embodiment of the present invention. This embodiment monitors the connection and disconnection of a display and adjusts the size of the full-screen window in real time to achieve preferential display of the authorized window. The method specifically includes the following steps:

[0055] S101, monitoring the user authorization pop-up request of the Linux system Polkit service.

[0056] First, you need to configure the operating system environment to support the dependency of the authorization pop-up window. You need to confirm the installation of the policykit-1 framework for managing management policies and privileges, and confirm the installation of ukui-polkit for the authorization pop-up agent, ukui-kwin window manager, and ukui-settings-daemon configuration management backend. For example, when starting the user desktop environment, you can use the above configuration to automatically start the application desktop file: / etc / xdg / autostart / polkit-ukui-authentication-agent-1.desktop

[0057] And the authorization pop-up window backend program that automatically starts at login: / usr / lib / x86_64-linux-gnu / ukui-polkit / polkit-ukui-authentication-agent-1.

[0058] The authorization pop-up window backend program monitors the user's authorization pop-up window request by registering a listener for the Polkit service.

[0059] S102, responding to the user's authorization pop-up request, creating a full-screen window and setting the window to a top state.

[0060] When the authorization pop-up window backend program receives the user's authorization pop-up window request by monitoring the Polkit service, it responds to the user's authorization pop-up window request by creating a full-screen window and setting the full-screen window's properties to be pinned to the top, covering the entire screen so that the user can only operate within the full-screen window, preventing the user from operating parts outside the full-screen window.

[0061] S103: updating the position of the full-screen window in real time according to the insertion and removal of the display, and adjusting the size of the full-screen window to the maximum window size visible in the current display mode of the system.

[0062] According to the maximum visible window size in the current display mode of the system, the size of the full-screen window is set to be consistent with the maximum window size, so that the full-screen window can cover all screens. By monitoring the insertion or removal of the display, the coordinate changes of the display area are obtained. Connecting a display will increase the coordinate range of the display area, and unplugging the display will reduce the coordinate range of the display area. The position and size of the full-screen window are updated in real time according to the coordinate range of the display area to ensure that the size of the full-screen window is always consistent with the maximum visible window size in the current display mode, so that the full-screen window always covers all screens. For example, a new rule can be added to the full-screen window in the window manager, and the rule can be set to not limit the window size. The window size can be freely set within the application. The newly added rule can be bound to the full-screen window in the configuration file, so that the window manager no longer limits the size of the full-screen window, thereby making the above-mentioned full-screen window resizing method effective and achieving the effect of covering all screens.

[0063] S104: Set the full-screen window as a parent window, create an authorization window on the parent window, and display authorization interaction information in the authorization window.

[0064] The full-screen window covers the entire screen. The authorization window, as a child window of the full-screen window, is displayed on top of the parent window to display authorization information. This information is presented prominently to the user, allowing them to focus on the authorization operation. The authorization window inherits from the QDialog class and passes the parentWidget parameter to the full-screen window instance pointer when instantiating the authorization window. The authorization window class instance is then passed information such as the authorization purpose and the application icon requiring authorization through the information passing interface. The authorization window then displays the information content in the appropriate window location.

[0065] S105: Actively disable shortcut keys for switching workspaces and switching application windows.

[0066] The window manager responds to shortcut keys for switching workspaces and application windows. The authorized window program passes information about a list of disabled switching shortcut keys to the window manager's D-Bus interface, preventing the window manager from processing these shortcut keys. This disables the ability to switch workspaces and application windows via shortcut keys. The configuration manager also responds to shortcut keys to enter the window switcher. The authorized window program registers a service with a D-Bus service name agreed upon with the configuration manager and provides an interface for obtaining a list of disabled switching shortcut keys. Upon detecting a D-Bus service registration event that meets the service name criteria, the configuration manager calls the service's disabled shortcut key function interface and does not respond to the corresponding shortcut keys. This disables the ability to switch windows via shortcut keys by entering the window switcher. Disabling these shortcut keys ensures that the full-screen window and the authorized window display process cannot be switched to other workspaces or application windows by pressing shortcut keys, which would result in the authorization request being ignored. This method directly handles the disabling of the function corresponding to the specific shortcut key, without having to worry about the correspondence between the function and the shortcut key; in addition, the method of monitoring the D-Bus service registration and service exit signals can solve the problem of the shortcut key function being disabled due to the abnormal exit of the calling program.

[0067] S106: When receiving the user's authorization operation, close the full-screen window and restore the disabled shortcut keys.

[0068] When the user authorization operation is completed, the full-screen window is closed, and the configuration management backend exits by monitoring the registered D-Bus service. At the same time, the shortcut keys disabled by the service are automatically released, the shortcut key functions are restored, and the authorization operation is completed.

[0069] This embodiment creates a full-screen window based on the user's authorization pop-up request, and at the same time monitors the insertion or removal of the display. According to the change in the display area coordinates caused by the insertion or removal of the display, the position and size of the full-screen window are updated in real time, so that the size of the full-screen window always remains consistent with the maximum window size visible in the current display mode, thereby achieving the effect of covering the entire screen, so that the user can only operate within the full-screen window, and all other content on the screen is covered, ensuring the high priority of the authorized window. The switching shortcut key is shielded through the D-Bus interface to prevent the user from accidentally switching to other windows and ignoring the authorization information. At the same time, the shortcut key can be unblocked by monitoring the exit of the D-Bus service, avoiding the problem of the shortcut key being unavailable due to abnormal exit of the shortcut key disabling.

[0070] Example 2

[0071] Figure 2This is a flow chart of a method for authorizing a window to dominate the screen display in a multi-screen mode according to a second embodiment of the present invention. This embodiment is optimized based on the above embodiment. In this embodiment, S103 is specifically optimized as follows:

[0072] Get the maximum window size currently visible in the system, and set the size of the full-screen window to be consistent with the maximum window size;

[0073] Monitor and respond to the insertion or removal of the display, and obtain the latest display area coordinates according to the insertion or removal of the display;

[0074] The position and size of the full-screen window are updated in real time according to the latest display area coordinates.

[0075] Accordingly, the method for displaying an authorized window in a multi-screen mode provided by this embodiment specifically includes:

[0076] S201, monitoring the user authorization pop-up request of the Linux system Polkit service.

[0077] S202, responding to the user's authorization pop-up request, creating a full-screen window and setting the window to a top-most state.

[0078] S203, obtaining the maximum window size currently visible in the system, and setting the size of the full-screen window to be consistent with the maximum window size.

[0079] Based on the current number of screens in the system and the coordinates of the display area, the maximum visible window size is determined, and the size of the full-screen window is set to be consistent with the maximum window size, ensuring that the full-screen window can always maintain full-screen status and cover all screens under multiple screens. The maximum display operation area after all screens are configured according to the currently set display parameters is obtained through the geometry() interface of the QDesktopWidget class instance returned by the QApplication::desktop() interface, and then the full-screen window calls setGeometry() to set it to the aforementioned area size.

[0080] S204 , monitoring and responding to the insertion or removal action of the display, and obtaining the latest display area coordinates according to the insertion or removal action of the display.

[0081] Monitor the insertion or removal of the monitor, adjust the coordinates of the display area accordingly, and generate the latest display area coordinates. Monitor the resized, workAreaResized, primaryScreenChanged, and screenCountChanged signals of the QDesktopWidget class instance obtained by QApplication::desktop(), and re-obtain the geometry() coordinates and size of the QDesktopWidget upon receiving the signals.

[0082] S205: updating the position and size of the full-screen window in real time according to the latest display area coordinates.

[0083] According to the coordinates and size obtained by the geometry() interface of the QDesktopWidget above, the full-screen window is set to the same coordinates and size of the QRect through setGeometry to cover the entire display area, keeping the size of the full-screen window able to cover all screens.

[0084] S206: Set the full-screen window as a parent window, create an authorization window on the parent window, and display the authorization interaction information in the authorization window.

[0085] S207: Actively disable shortcut keys for switching workspaces and switching application windows.

[0086] S208: Upon receiving the user's authorization operation, close the full-screen window and restore the disabled shortcut keys.

[0087] This embodiment obtains the latest display area coordinates by monitoring the insertion or removal of the display, and updates the position and size of the full-screen window in real time based on the latest display area coordinates. In a multi-screen scenario, even if the number of screens increases or decreases, the full-screen window can still maintain the effect of covering all screens, avoiding users from operating other parts and ensuring the priority of the authorized window.

[0088] Optionally, the method further includes:

[0089] According to the transparency effect support option of the window compositor, the transparency attribute of the full-screen window is determined, and the corresponding background image is drawn according to the transparency attribute and the number of screens. The image size of the background image is consistent with the corresponding screen size.

[0090] Whether the current environment supports window compositing is determined by checking whether the value of the property compositingType of the window compositor's D-Bus service interface (service: org.ukui.KWin, path: / Compositor, interface: org.freedesktop.DBus.Properties) is "none". If it is not "none", window compositing is supported to set the full-screen window. For example, if the window compositor supports the transparent attribute, the full-screen window is set to transparent. If the transparent attribute is not supported, it is necessary to draw the background image of the corresponding screen on the full-screen window according to the number of multiple screens and the size of each screen, and keep the size of the background image consistent with the size of the corresponding screen. The background image of the corresponding screen is displayed on the corresponding screen through the full-screen window to achieve an effect close to full transparency, so that the full-screen window's coverage of all screens is less sensitive or even imperceptible, thereby improving the user experience.

[0091] Example 3

[0092] Figure 3 This is a flowchart of a method for authorizing a window to dominate the screen display in a multi-screen mode according to a third embodiment of the present invention. This embodiment is optimized based on the above embodiment. In this embodiment, S105 is specifically optimized as follows:

[0093] Call the D-Bus interface to generate a list of switching shortcut keys to be blocked, and add a disabled status flag to each shortcut key in the list;

[0094] Register the D-Bus service, shield the switching shortcut key according to the switching shortcut key shielding list and the disabled state flag of each shortcut key in the list, and update the disabled state flag of the shortcut key.

[0095] Accordingly, the method for displaying an authorized window in a multi-screen mode provided by this embodiment specifically includes:

[0096] S301, monitoring the user authorization pop-up request of the Linux system Polkit service.

[0097] S302, responding to the user's authorization pop-up request, creating a full-screen window and setting the window to a top-most state.

[0098] S303: updating the position of the full-screen window in real time according to the insertion and removal of the display, and adjusting the size of the full-screen window to the maximum window size visible in the current display mode of the system.

[0099] S304: Set the full-screen window as a parent window, create an authorization window on the parent window, and display authorization interaction information in the authorization window.

[0100] S305: calling the D-Bus interface to generate a switching shortcut key shielding list, and adding a disabled state flag to each shortcut key in the list.

[0101] The D-Bus interface is a general interface that the window manager can use to disable shortcut keys. When obtaining the shortcut keys to be disabled and generating a list of disabled shortcut keys through this interface, a disabled status flag can be added to each shortcut key to record and indicate the disabled status of the shortcut key. The window manager's D-Bus interface (service: org.ukui.KWin, path: / Kwin, interface: org.ukui.KWin) is called to set a list of disabled shortcut keys such as "Switch One Desktop to the Left" through the blockShortcut interface. The configuration manager is also registered with the D-Bus service named "org.ukui.settingsDaemon.shortcut.ukui-polkit," which is listened to by the configuration manager. This interface, called blockShortcuts, is used to obtain the disabled shortcut key list, allowing the configuration manager to obtain information about the shortcut keys to be blocked. In this way, before responding to shortcut keys that are not registered with kglobalaccel, the disable status flag can be used to determine whether to continue responding during subsequent disablement. This can not only manage the disabling process of shortcut keys registered with kglobalaccel, but also manage shortcut keys that are not registered with kglobalaccel. The window manager's method of disabling shortcut keys through the D-Bus interface is compatible with different display service scenarios such as xorg and x-wayland scenarios.

[0102] S306: Register the D-Bus service, shield the switching shortcut key according to the switching shortcut key shielding list and the disabled state flag of each shortcut key in the list, and update the disabled state flag of the shortcut key.

[0103] The configuration management backend registers the D-Bus service, which obtains the switching shortcut key blocking list and blocks all shortcut keys in the table based on the list. At the same time, it updates the disabled status flag indicating the disabled state, making it easier to determine the disabled state of the shortcut keys when disabling them later. This makes it compatible with more display service scenarios.

[0104] S307: Upon receiving the user's authorization operation, close the full-screen window and restore the disabled shortcut keys.

[0105] When the user completes the authorization operation, the corresponding shortcut keys are automatically unblocked by monitoring the exit of the D-Bus service, avoiding the problem of shortcut keys becoming unavailable due to abnormal exit of the caller that disables the shortcut keys. In addition, by disabling shortcut keys through the general D-Bus interface of the configuration management backend, it is compatible with different display service scenarios such as xorg and x-wayland scenarios.

[0106] This embodiment disables shortcut keys by calling the general interface of the window manager, and identifies the disabled state of the shortcut keys by adding a disabled state flag, which facilitates the management of different shortcut key disabling methods. The shortcut keys are restored by monitoring the service corresponding to the interface, avoiding the unavailability of shortcut keys caused by abnormal exit, and is also compatible with more display service scenarios.

[0107] In an optional implementation of this embodiment, S302 includes:

[0108] Receive Polkit's user authorization pop-up request.

[0109] The authorization pop-up window backend program receives the user's authorization pop-up window request by monitoring the Polkit service.

[0110] Create a QWidget window with a size that is the maximum visible window size based on the system's current display mode.

[0111] Create a QWidget full-screen window. The size of the full-screen window is consistent with the maximum visible window size in the system's current display mode. The full-screen window is set through the window manager. The window manager contains layers from low to high, such as DesktopLayer, BelowLayer, NormalLayer, DockLayer, AboveLayer, and UnmanagedLayer. The window manager draws windows in order from low to high according to the hierarchy. The level of the full-screen window is AboveLayer, which ensures that the full-screen window is displayed above the desktop, taskbar, and general windows. At the same time, it does not affect the display level of windows with higher priority functions such as system notification windows and lock screen windows, ensuring that higher priority windows can still be displayed on the upper layer of the full-screen window.

[0112] Set the QWidget window properties to borderless, top, and transparent.

[0113] By setting the full-screen window to be borderless and transparent, so that the window directly covers the taskbar instead of hiding it, the authorization pop-up window can be kept on top while displaying some dynamic information of the taskbar, such as application message reminders in the tray, period date display, etc., to prevent users from missing other reminders they want to pay attention to.

[0114] For example, by:

[0115] setWindowFlags(Qt::Tool | Qt::WindowStaysOnTopHint | Qt::FramelessWindowHint);

[0116] Among them, Qt::Tool sets the window as a tool window (Tool Window), and tool windows usually have no taskbar entries; Qt::WindowStaysOnTopHint forces the window to always appear on top of other windows, and the window will be placed above all other non-top windows (unless other windows also set this flag); Qt::FramelessWindowHint: removes the window border and title bar, and the window has no title bar, border, close / minimize buttons and other system decorations; through setWindowOpacity(0.25); adjust the window transparency to 0.25, 0 is fully transparent, and 1 is opaque.

[0117] Example 4

[0118] Figure 4 This is a flowchart of a method for authorizing a window to dominate the screen display in a multi-screen mode according to a fourth embodiment of the present invention. This embodiment is optimized based on the above embodiment. In this embodiment, S104 is specifically optimized as follows:

[0119] Set the full-screen window as the parent window, and create an authorization window based on QDialog on the parent window;

[0120] The authorization interaction information is displayed in the authorization window, and the authorization interaction information includes: authorization description information, authorization program icon, and authorized user list.

[0121] Accordingly, the method for displaying an authorized window in a multi-screen mode provided by this embodiment specifically includes:

[0122] S401, monitoring the user authorization pop-up request of the Linux system Polkit service.

[0123] S402, responding to the user's authorization pop-up request, creating a full-screen window and setting the window to a top-most state.

[0124] S403: updating the position of the full-screen window in real time according to the insertion and removal of the display, and adjusting the size of the full-screen window to the maximum window size visible in the current display mode of the system.

[0125] S404: Set the full-screen window as a parent window, and create an authorization window based on QDialog on the parent window.

[0126] After the full-screen window covers all screens, a QDialog window is created on the upper layer of the full-screen window in the form of a child window for displaying authorization information, so as to inherit the properties of the full-screen window and display the authorization information with high priority.

[0127] S405: Display authorization interaction information in the authorization window, where the authorization interaction information includes authorization description information, authorization program icon, and authorized user list.

[0128] In order to facilitate users to obtain the information that needs to be authorized and determine whether to authorize based on the authorization information, the authorization interaction information displayed in the authorization window needs to describe the authorization content, as well as the program icon that needs to obtain authorization, and the list of users who are granted permission. Users can intuitively understand the authorization content through the above authorization interaction information and quickly perform authorization operations.

[0129] S406: Actively disable shortcut keys for switching workspaces and switching application windows.

[0130] S407: Upon receiving the user's authorization operation, close the full-screen window and restore the disabled shortcut keys.

[0131] This embodiment uses the full-screen window as the parent window and creates an authorization window on the upper layer of the full-screen window in the form of a child window, which facilitates attribute inheritance, improves the display priority of authorization information, makes it easier for users to obtain authorization information, and improves user authorization efficiency.

[0132] Specifically, the method further includes:

[0133] Set the authorization window as a modal dialog box.

[0134] Since the authorization window is a child window of the full-screen window, the full-screen window covers the entire screen, and the authorization window only occupies part of the full-screen window. When the user clicks on a full-screen window other than the authorization window, although the full-screen window can block other applications by covering them, the user still needs to be prompted to quickly perform the authorization operation.

[0135] Monitor the mouse click area and trigger the shaking reminder effect of the modal dialog box according to the mouse click area.

[0136] By monitoring the mouse click area, when the mouse clicks on an area outside the authorization window, the modal dialog box will be triggered to shake.

[0137] Example 5

[0138] Figure 5This is a schematic diagram of the structure of a device for displaying an authorized window occupying a screen in a multi-screen mode according to a fifth embodiment of the present invention. In this embodiment, the device for displaying an authorized window occupying a screen in a multi-screen mode includes:

[0139] Request monitoring module 810, used to monitor user authorization pop-up requests of the Linux system Polkit service;

[0140] The request response module 820 is used to respond to the user's authorization pop-up window request and create a full-screen window to set the window to the top state;

[0141] Window update module 830, used to update the position of the full-screen window and adjust the size of the full-screen window in real time according to the insertion and removal of the display;

[0142] Authorization information module 840, used to set the full-screen window as the parent window and create an authorization window on the parent window to display the authorization interaction information;

[0143] The shortcut key shielding module 850 is used to proactively disable the shortcut keys for switching workspaces and switching application windows;

[0144] The window restoration module 860 is configured to close the full-screen window and restore disabled shortcut keys upon receiving an authorization operation from the user.

[0145] This embodiment monitors the user's authorization pop-up window request through the request monitoring module, responds to the monitored user authorization pop-up window request through the request response module, adjusts the size of the full-screen window through the window update module, creates an authorization window through the authorization information module and displays the authorization interaction information in the authorization window, disables the switching shortcut key through the shortcut key shielding module, and restores the disabled shortcut key after the full-screen window is closed through the window recovery module. By creating a full-screen window according to the user's authorization pop-up window request, and monitoring the insertion or removal of the display, the position and size of the full-screen window are updated in real time according to the change in the display area coordinates caused by the insertion or removal of the display, so that the size of the full-screen window always remains consistent with the maximum window size visible in the current display mode, thereby achieving the effect of covering all screens, so that the user can only operate in the full-screen window, and other content on the screen is covered, ensuring the high priority of the authorization window. The switching shortcut key is shielded through the D-Bus interface to prevent the user from switching to other windows by mistake and ignoring the authorization information. At the same time, the shortcut key can be disabled by monitoring the exit of the D-Bus service, avoiding the problem of shortcut key unavailability caused by abnormal exit of the shortcut key disablement.

[0146] The authorized window screen-dominating display device in the multi-screen mode provided by an embodiment of the present invention can execute the authorized window screen-dominating display method in the multi-screen mode provided by any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the execution method.
