Description of drawings
Figure 1 shows that device sketch described in the utility model;
Figure 2 shows that the flow chart of steps that device work described in the utility model realizes.
Embodiment
Device sketch described in the utility model as shown in Figure 1, in video conference terminal equipment, be provided with a video card of supporting that double screen shows, and selection control unit, this terminal equipment is connected with two or more display, when terminal equipment starts video conferencing system, carry out the workflow of following steps (being shown as example) as shown in Figure 2 with double screen:
Check terminal presentation facility when step S1, video conferencing system startup, obtain the relevant information of display, also determine that automatically a display is a basic display unit.
Under the double screen display mode, a basic display unit and one are arranged from display (under the situation that multi-screen shows, can be for a plurality of) from display.When terminal equipment started video conferencing system software, the automatic calls application interface function of meeting obtained display apparatus information, and selects a display as basic display unit automatically.For example call display and enumerate interface function:
EnumDisplayMonitors (HDC hdc, LPCRECT lprcClip, MONITORENUMPROC lpfnEnum, LPARAM dwData) searches and enumerates the display that is connected with it and can operate as normal; The user can be according to actual needs (for example: can select projecting apparatus etc. if will show big picture), selects wherein two as the double screen display device.After the user has selected two demonstrations, call an interface function again, for example:
GetMonitorInfo (HMONITOR hMonitor, LPMONITORINFO 1pmi) obtains the specifying information of each selected display device.These information comprise display display position, working region size (display resolution) etc.
Monitor information by obtaining is determined the basic display unit of one of them display as conference system then.Usually, for convenience of calculation, the basic display unit of selection operation system default (screen upper left corner coordinate points is (0,0)) is as the basic display unit of conference system.
The screen coordinate of step S2, setting basic display unit, and calculating is from the relative screen coordinate of display.
After having determined basic display unit, determine the indication range of basic display unit according to the information of the basic display unit that has obtained.Usually the coordinate in the basic display unit upper left corner is (0,0), and the lower right corner is a maximum coordinates, i.e. maximum indication range of She Zhiing.According to the physical location of principal and subordinate's display relation with calculate from the relative screen coordinate of display from the relevant information of display (comprising the ultimate resolution that can support from display, the maximum magnitude that can show etc.) with respect to basic display unit.
For example: the ultimate resolution of supposing basic display unit is 1024*768, and its upper left corner coordinate is (0,0), and lower right corner coordinate is (1024,768) so.From the ultimate resolution of display is 800*600, and should be positioned at the right side of basic display unit from the physical location of display.So just can determine that be (1024,0) from display with respect to zero point of basic display unit, the trend of X-axis to the right, the trend of Y-axis is downward, is (1824,600) thereby computing draws this coordinate from the display device lower right corner.In like manner can be provided with at other physical location of main display device from display device, as if the upper left side that is positioned at basic display unit from display, then its screen coordinate will be the negative coordinate figure.
Step S3, the different window body interface of video conference is corresponding with the screen coordinate zone of principal and subordinate's display respectively demonstrates described different window body interface by principal and subordinate's display.
Because the different window body interface of video conference has different identification informations, different window interfaces can be provided with its corresponding displaing coordinate zone respectively, continue to use example: the viewing area that main interface is set arrives (1024 for (0,0), 768), then this main interface will be presented on the basic display unit; Be (1024,0) to (1824,600) if the viewing area at data conferencing interface is set, then this data conferencing interface will be presented at from display.After handling like this, not only can realize two different interfaces are presented at respectively on two displays, and because the coordinate of principal and subordinate's display device is continuous, so when mouse is moved beyond the right side edge of basic display unit, will occur, be convenient to mouse like this and between different interfaces, operate from display device.
Step S4, according to the forms at video conference interface, visit the information of its place display.
Video conferencing system in use allows the user arbitrarily to change the position of a certain window interfaces, can cause this window interfaces to move to the situation of another indicator screen from certain indicator screen, therefore which display need understand window interfaces timely belongs to, so that make other forms information display layouts reasonable.For example, a certain interface is presented at first from display, and a certain moment is moved on the basic display unit, need show an information now in the middle of the display at this forms place, so can be by calling an interface function:
GetMonitorFromWindow (HWND hwnd, DWORD dwFlags) obtains the display (basic display unit) at this forms place, goes out screen intermediate point coordinate and display reminding information according to calculation of parameter such as the coordinate of display, viewing areas then.
