The home window that provides of system is square window in actual applications, so at first create a square window, and this square window and video window formation mapping relations are set, so-called mapping relations refer to corresponding relation, that is, this square window and video window are one-to-one relationships.Each window in system has a window ID in order to identify this window, and the window ID of each window is unique.That is be exactly to form mapping relations one to one between the window ID of window ID and corresponding video window of this square window in the practical application.By the mapping relations that form, just can utilize mapping relationship searching to go out the window ID of another corresponding with it window if know the ID of a window.
Step 203B: in the device context of the square window object of described establishment, draw the window signal source name of obtaining;
A device description table section is arranged in each window in system, can in this device description table section, carry out associative operation, in step 203B, only in device context, draw the window signal source name.When drawing the window signal source name, required font type and font size can be set, such as being set to No. three, No. five, the Song typeface or regular script.A kind of font type and size are set arbitrarily according to the actual requirements.
Step 203C: obtain the character shape zone of the signal source name of drafting, the type of described square window is set to the character shape window;
Draw after the window signal source name in the device description table section of square window, signal source name is to exist with character style, just can obtain the character shape zone that this window signal source name takies, and the type of square window is set to the character shape window then.
Step 204: described character shape window is presented in the described first area.
Preferably, step 204 comprises: step 204A and step 204B,
Step 204A: the coordinates regional that described character shape window is set: the apex coordinate (X2 corresponding with any one summit of the video window that obtains, Y2), the wide W2 of window and high H2, must meet the following conditions: X1＜=X2＜=(X1+W1), Y1＜=Y2＜=(Y1+H1), (X2+W2)＜=(X1+W1), (Y2+Y2)＜=(Y1+Y1);
Such as: the coordinate range when the first area of determining is: lower left corner coordinate (1000,1000), top left corner apex coordinate are that (1000,3000), lower right corner apex coordinate are (4000,1000) and upper right corner apex coordinate (4000,3000).Then the mode according to step 204A can arrange the coordinates regional of character shape window in the scope of first area.Certainly, also can adopt other modes, fall within the scope of first area as long as can realize the coordinates regional of character shape window.
Step 204B: the character shape window is moved to the coordinates regional of setting, and be set to the top set demonstration.
Such as: when the coordinates regional of the character shape window that arranges is: upper left corner coordinate (2000,2500) lower left corner coordinate (2000,1500), upper right corner coordinate (3000,2500), lower right corner coordinate (3000,1500) time, this window is moved to coordinates regional, be set to top set then and show.
