Description

Technical Field

[0001] This invention relates to the field of operating system technology, and specifically to a method, system, medium, and product for avoiding shortcut key conflicts in an operating system. Background Technology

[0002] In the graphical environment of the Linux operating system, the system provides a shortcut key setting function. The system captures shortcut keys to ensure that only the system can receive the shortcut key combination. For example, the operating system generally triggers the display and hiding of the Start Menu window by capturing the Super key release event. The Super key may have different names, such as Super key (Linux system), Win key (Windows system), Start key, Command key (Mac system), etc. Currently, the Linux operating system is still mainly based on the X Windows window system (Xorg). In the X Windows window system, XGrabKey is generally used to capture keyboard keys. XGrabKey input includes modifier keys and normal keys. Modifier keys include Ctrl, Shift, Alt, Super, etc., and normal keys include the 26 letters and special characters, such as "A", "B", "=", etc. A shortcut key consists of one, more, or any modifier keys (including zero) + one normal key or any normal key (including zero), such as Super+D, Ctrl+Alt+A, AnyModifier+B, Ctrl+AnyKey. The physical key corresponding to Super is special; this physical key can be used as both a modifier key and a normal key. When used as a modifier key, its corresponding keycode is Super; when used as a regular key, the keycode is Super_L or Super_R. However, if the operating system's shortcut keys include both Super and Super + other regular keys, it can lead to shortcut key conflicts or duplicate shortcut key responses. For example... Figure 1 As shown, when a system process captures the shortcut key combination Super + any other key, it can correctly receive the Super physical key press and release events. However, it will also receive the Super + other ordinary key press and release events simultaneously. If a non-system process needs to capture Super + other ordinary keys (e.g., Super + D) at this time, capturing Super + D will fail, affecting the functionality of the non-system process. Figure 2As shown, to avoid shortcut key capture conflicts, for a single Super key, it should be captured using Super_L or Super_R. This ensures that non-system processes can correctly capture the Super + normal key shortcut. When the system captures both Super_L or Super_R and Super + D, if the user presses Super + D, according to the normal processing flow, both shortcuts will be activated simultaneously, causing duplicate shortcut responses. Therefore, resolving the shortcut key conflict between the single Super key and Super combination keys in the Linux operating system has become a critical technical problem that urgently needs to be solved. Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide a method, system, medium, and product for avoiding shortcut key conflicts in an operating system, addressing the aforementioned problems of the prior art. This invention aims to overcome the problem of shortcut key conflicts between single and combination keys of various physical keys, including the Super key, in the Linux operating system, which leads to the activation of two shortcut keys and causing repeated shortcut key responses, thereby improving the user experience and flexibility of shortcut keys in the Linux operating system.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A method for avoiding shortcut key conflicts in an operating system includes the following steps: S101, initialize the target button and set the trigger prevention flag to true; S102, when a shortcut key press event is received, if the shortcut key press event is a single key event of the target key, the trigger prevention flag is set to false; otherwise, the trigger prevention flag is set to true and the combined shortcut key behavior of the target key and other ordinary keys in the shortcut key press event is triggered; when a shortcut key release event is received, if the shortcut key release event is a single key event of the target key and the trigger prevention flag is false, the single key behavior of the target key is triggered.

[0005] Optionally, when triggering a single key action of the target key in step S102, the trigger prevention flag is also set to true.

[0006] Optionally, steps S101 and S102 are execution steps in the target program, and step S101 is the execution step when the target program is executed.

[0007] Optionally, the target key in step S101 is the Super key.

[0008] Optionally, the single key event of the target key in step S102 refers to the Super_L event or Super_R event of the Super key.

[0009] Optionally, step S102 includes: S201, monitor shortcut key press events or shortcut key release events. If a shortcut key press event or shortcut key release event is received, proceed to step S202. S202, determine whether the received shortcut key press event is true. If true, proceed to step S203; otherwise, if the received shortcut key release event is true, proceed to step S206. S203, determine whether the shortcut key press event is the Super_L event or the Super_R event of the Super key. If it is the Super_L event or the Super_R event of the Super key, then jump to step S204. S204, set the trigger prevention flag to false, and jump to step S201; S205, set the prevent trigger flag to true, trigger the shortcut key combination behavior of the target key and other ordinary keys in the shortcut key press event, and jump to step S201; S206, determine whether the shortcut key release event is the Super_L event or Super_R event of the Super key and whether the trigger prevention flag is false. If true, set the trigger prevention flag to true and trigger the single Super key key press behavior of the target key, then jump to step S201.

[0010] Optionally, the combined shortcut key behavior of the target key and other ordinary keys in the trigger shortcut key press event refers to the behavior of displaying the desktop by triggering the Super key and the D key, and the single key behavior of triggering the target key refers to the behavior of displaying or hiding the start menu window by triggering a single Super key.

[0011] Furthermore, the present invention also provides a system for avoiding shortcut key conflicts in an operating system, comprising a microprocessor and a memory interconnected thereto, wherein the microprocessor is programmed or configured to execute a method for avoiding shortcut key conflicts in the operating system.

[0012] Furthermore, the present invention also provides a computer-readable storage medium storing a computer program or instructions that are programmed or configured to execute, via a processor, a method for avoiding shortcut key conflicts in the operating system.

[0013] In addition, the present invention also provides a computer program product, including a computer program or instructions that are programmed or configured to execute, via a processor, a method for avoiding shortcut key conflicts in the operating system.

[0014] Compared with existing technologies, the present invention mainly achieves the following beneficial effects: The method for avoiding shortcut key conflicts in the operating system of the present invention includes setting the prevent trigger flag to true for the target key during initialization; when a shortcut key press event is received, if the shortcut key press event is a single key event of the target key, the prevent trigger flag is set to false; otherwise, the prevent trigger flag is set to true and the combined shortcut key behavior of the target key and other ordinary keys in the shortcut key press event is triggered; when a shortcut key release event is received, if the shortcut key release event is a single key event of the target key and the prevent trigger flag is false, the single key behavior of the target key is triggered. By preventing the trigger flag and combining the combined processing of shortcut key press events and shortcut key release events, the present invention can overcome the problem of simultaneous activation of two shortcut keys and repeated shortcut key responses caused by shortcut key conflicts of single keys and combination keys of various physical keys, including the Super key, under the Linux operating system, thereby improving the shortcut key user experience and flexibility under the Linux operating system.

[0018] Figure 4 This is a detailed flowchart illustrating the method of an embodiment of the present invention. Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 3 As shown, the method for avoiding shortcut key conflicts in the operating system of this embodiment includes the following steps: S101, initialize the target button and set the trigger prevention flag to true; S102, when a shortcut key press event is received, if the shortcut key press event is a single key event of the target key, the trigger prevention flag is set to false; otherwise, the trigger prevention flag is set to true and the combined shortcut key behavior of the target key and other ordinary keys in the shortcut key press event is triggered; when a shortcut key release event is received, if the shortcut key release event is a single key event of the target key and the trigger prevention flag is false, the single key behavior of the target key is triggered.

[0021] In step S102 of this embodiment, when triggering a single key action of the target key, the trigger prevention flag is also set to true.

[0022] In this embodiment, steps S101 and S102 are executed in the target program, and step S101 is the execution step when the target program is running.

[0023] In this embodiment, the target key in step S101 is the Super key, so the trigger prevention flag is named block_super_triggered. In step S101, the trigger prevention flag block_super_triggered is set to true for initialization. It should be noted that the method in this embodiment can be applied to the shortcut key conflict problem of single keys and combination keys of modifier keys such as Ctrl, Shift, Alt, and Super. By solving the shortcut key conflict problem of single keys and combination keys of modifier keys, the richness of shortcut keys in the system is greatly expanded.

[0024] In this embodiment, the single key event of the target key in step S102 refers to the Super_L event or Super_R event of the Super key.

[0025] like Figure 4 As shown, step S102 in this embodiment includes: S201, monitor shortcut key press events or shortcut key release events. If a shortcut key press event or shortcut key release event is received, proceed to step S202. S202, determine whether the received shortcut key press event is true. If true, proceed to step S203; otherwise, if the received shortcut key release event is true, proceed to step S206. S203, determine whether the shortcut key press event is the Super_L event or the Super_R event of the Super key. If it is the Super_L event or the Super_R event of the Super key, then jump to step S204. S204, set the trigger prevention flag block_super_triggered to false, and jump to step S201; S205, set the block_super_triggered flag to true, trigger the shortcut key combination behavior of the target key and other ordinary keys in the shortcut key press event, and jump to step S201; S206, determine whether the shortcut key release event is the Super_L event or Super_R event of the Super key and whether the blocking trigger flag block_super_triggered is false. If true, set the blocking trigger flag block_super_triggered to true and trigger the single Super key key action of the target key, then jump to step S201.

[0026] In Linux systems, the Super key is typically used to show or hide the Start Menu window. There are many common Super key combinations, and these combinations vary depending on the desktop environment. For example, Super+D shows the desktop. Taking the conflict between the single Super+D shortcut and its combination as an example, the combined shortcut of the target key and other ordinary keys triggering the Super and D keys to show the desktop refers to the single Super key press.

[0027] Assume the system is configured with both Super_L and Super+D shortcut keys. Super_L corresponds to showing / hiding the Start menu window, and Super+D shows the desktop; a terminal window is already open on the desktop. The steps to verify the method in this embodiment include: 1) Pressing and releasing the Super physical key. Upon release, the shortcut key release event successfully triggers the behavior of showing the Start menu window. 2) Pressing and releasing the Super physical key again. Upon release, the shortcut key release event successfully triggers the behavior of hiding the Start menu window. 3) Pressing both the Super and D physical keys simultaneously, the shortcut key press event successfully triggers the behavior of showing the desktop, all desktop windows are hidden, and the behavior of showing the Start menu window is not triggered.

[0028] In summary, the method of this embodiment includes initializing the target key by setting the prevent trigger flag to true; when a shortcut key press event is received, if the shortcut key press event is a single key event of the target key, the prevent trigger flag is set to false; otherwise, the prevent trigger flag is set to true and the combined shortcut key behavior of the target key and other ordinary keys in the shortcut key press event is triggered; when a shortcut key release event is received, if the shortcut key release event is a single key event of the target key and the prevent trigger flag is false, the single key behavior of the target key is triggered. This embodiment, by preventing the trigger flag and combining the processing of both shortcut key press and shortcut key release events, can overcome the problem of shortcut key conflicts between single and combination keys of various physical keys, including the Super key, under the Linux operating system, which leads to the activation of two shortcut keys and causes repeated shortcut key responses, thus improving the shortcut key user experience and flexibility under the Linux operating system.

[0029] Furthermore, this embodiment also provides a system for avoiding shortcut key conflicts in an operating system, including a microprocessor and a memory interconnected, wherein the microprocessor is programmed or configured to execute a method for avoiding shortcut key conflicts in the operating system.
