Detailed description of the invention
For further setting forth the effect of technological means that the present invention takes and acquirement, below in conjunction with accompanying drawing and preferred embodiment, to technical scheme, carry out clear and complete description.
Refer to Fig. 1, for the schematic flow sheet of windows switching method of the present invention.Windows switching method of the present invention, comprises the following steps:
S101 real-time judge current system put whether front window meets default switching condition, if met, its window pointer is added in window data chained list；
As one of them embodiment, with preset time period for the cycle, circulation obtains the window handle putting front window of current system；Described window handle according to obtaining judges whether this window meets default switching condition.
As one of them embodiment, described preset time period is 20 milliseconds.
Window record part when system is run, take and avoid mistakes and omissions window record reducing system resource as far as possible, by judging between optimal time T0, use thread to press T0 and inquire about current system theactivewindow, judging after getting window handle whether this window meets switch window condition F0, window pointer is updated in window data chained list by qualified window.
The time of T0 presses value and calculates:
The ghost phenomena of human eye, surpasses 24 frames/second human eye to display image change and can not be identified, therefore T0 < (1/24) second；
The click speed of keyboard or mouse is general only to 300 beats/min, and as keyboard combination key (alt+tab) can only reach about 100/ minute, < (1/24) second can meet the windows exchange that user is operated by keyboard and mouse to T0；
Carry out more fast to the operation of window query, then system needs the more time to process query manipulation, and the efficiency that namely the more slow then overall system of the thread cycle of window record runs is more high.
Therefore, the cycle of (1/24) can be accelerated 2 times, use 1/50 second namely 20 milliseconds to use to meet system.
Condition F0 presses conditional filtering:
Whether oneself is chained list top-level windows to current window, is do not process；
Current window whether system desktop subwindow or menu or information window, be do not process；
Current window meets the eliminating window that user independently screens, as respond module generate window W, be do not process.
In S102 circulation reading the first list, the windows exchange request of the user of record, often reads a windows exchange request, then obtain the last window pointer putting front window from described window data chained list；
Shared lock Lock worker thread poll can be used to process, if lock Lock is lock-out state, then only record user's switch window asks the first list List1.
It is unlocking condition as locked Lock, the first list List1 that thread reads the switch window request of record user by T0 speed loop can be started, read request, then take out from window data chained list and put front theactivewindow pointer P last time.
If the window pointer that the last time that S103 obtains puts front window is effective, then this window pointer is added in the second list；
As one of them embodiment, if the last time obtained puts the window pointer non-NULL of front window, window attribute is not hidden state, and window size is not zero, then judge that this window pointer is effective, add it in the second list.
As one of them embodiment, after obtaining the window pointer that the last time puts front window from window data chained list, if the window pointer that the last time obtained puts front window is invalid, then from described window data chained list, delete this window pointer.
F1 as effective in pointer P then pointer is sent to treats that respond module is waited to put front theactivewindow list, i.e. the second list List2, and lock Lock is locked, otherwise from window data chain statistical form except this window pointer, take forward the activation pointer of last time by window data chained list successively and process.
The condition of window effectiveness F1 can be: window pointer P non-NULL, window still suffers from；Window attribute is not hidden state；Window size is not 0.
The window pointer in described second list is read in S104 circulation, before being put by corresponding window.
Outside the visible viewing area of user, generate a window W being sized to 1*1, assistant window during as theactivewindow during initialization, and be set to hidden state.Separately starting thread during initialization to read by T0 speed loop and wait to put front theactivewindow list, i.e. the second list List2, if Lock state is for unblanking, program performs operation P before window is put after reading request, after completing, lock Lock is set to unlocking condition.
Before window is put, operation P has 3 parts:
Use system API arranges before window puts；
Such as above-mentioned 1 setup failed, then first arrange before window W puts, then perform to put front activation manipulation by front window system API to be put；
If front window to be put is without response, then before respond module waits that this window cannot be put after 1 second, then the request of this switching action is abandoned, wait handover request next time.
Preferably, can increasing a key device on PC, button performs handover operation after being activated by a user, and puts before front theactivewindow puts by last time after each click keys.Response time was less than 0.1 second.
Preferably, a service receiving changeover program can be received on PC, receive the switching message of switching message that network is sent to or other process of user, then perform windows exchange and operate.
Refer to Fig. 2, for applying the fundamental diagram of a preferred embodiment of windows switching method of the present invention.Each module call relation is as shown in the drawing.
