Problems solved by technology
In order to ensure that the user's operations are not confused on multiple screens, the user interface of the embedded device is limited to the main window at a certain time. To operate on the auxiliary window, it is necessary to switch the user interface to the auxiliary window through certain operations. After the operation is completed It may be necessary to return to the original main window for other operations, and so on

Embodiment Construction
[0025] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:
[0026] like figure 1 As shown, a method for switching primary and secondary windows of an embedded device in the present invention,
[0027] Ⅰ The graphical interface program of the embedded device detects the user's mouse operation;
[0028] Ⅱ When the program detects that the left mouse button is pressed, the program records the time T0 when the mouse is pressed, and the coordinate point (X0, Y0) of the mouse on the screen at that time, and sets the record flag MouseHold = 1;
[0029] Ⅲ When the program detects that the left mouse button is released, cancel the record flag MouseHold=0 in step 2;
[0030] Ⅳ When the program detects that the mouse is moving, if MouseHold is 1, the mouse is pressed and moving, the program obtains the current time Tn and the current position of the mouse on the screen (Xn, Yn), and calculates:
[0031] Time = Tn - T0;
[0032] ...

The invention discloses a method for switching a main window and an auxiliary window by an embedded device. A graphical interface program of the embedded device detects user mouse operation; the program records the time when a left button of a mouse is pressed down and the moving distance of the mouse with the left button pressed down at the moment, and when the fixed condition is met, the program triggers switching of a graphical interface between the main window and the auxiliary window. According to the method, the problem of window rapid switching of an embedded DVR, an NVR and a hybrid type DVR device through the left button of the mouse is solved, and the method has the advantages of being convenient and rapid to operate, flexible in operation, good in usability, high in user experience, free of misoperation and the like. According to the mode, the main window and the auxiliary window can be rapidly switched, the usability requirement of users of the embedded DVR, the NVR and the hybrid type DVR device for rapid window switching is met, operation of the users is greatly facilitated, and the user experience is improved.
Description
technical field [0001] The invention belongs to the field of video monitoring, and in particular relates to a method for switching main and auxiliary windows of an embedded device. Background technique [0002] Embedded devices include embedded DVR (Digital Video Recorder) devices, embedded NVR (Network Video Recorder) devices and embedded hybrid DVR devices. [0003] Embedded DVR device is an embedded network video device that can connect to analog camera, dome camera, etc., and collect its video signal analogly, perform local output echo, and video encoding local storage, network real-time video transmission. [0004] The embedded NVR device is a front end that can connect and control the network IPC (Internet Protocol Camra, or network camera), store the video data from the IPC locally and forward it over the network, and decode and display the IPC collected data on the output interface of the NVR device. equipment for real-time video signals. [0005] Embedded hybrid D...
