-------------------------------------------------- ------------------------------ Overview In the eighth Win32ASM tutorials, the message box, dialog, Menu, resource, gdi, etc. New content, write a comprehensive article. The example of this article is a complex shape window. The shape of the window is automatically calculated according to the bitmap, which is the technology used in the small alarm clock I have written (everyone can go to my software release to download a look. Because the most example of the special shape window seen on the Internet is the most painted shape, or several squares and elliptical combination, no article points out how to draw such a model such as "Tang Duck" window. The algorithm used herein can automatically calculate the window shape according to the shape of the bitmap. In the source program, many code is mentioned earlier, mainly with the following parts: first establish a standard window. (Reference Window section) Setting the window as a special shape. (See the program analysis below) Update the window of the window in the WM_PAINT message of the window. (Reference graphical interface) Since the window does not have a title bar, a menu pops up when you right click on the window. (Reference Menu Heet) There is a "About this Program" item in the menu, there is a super knot text. (Reference window subclassification) There is a special API in Windows to achieve a special shape window, step is to build a region (Region), and region can be merged, so that several simple areas can be used to combine a complex area The API of the area, the establishment, merge area, and settings window has the following: CreateRectrgn (Left, Top, Right, Bottom) - Creating a rectangular area CreatellipticRGN (Left, Top, Right, Bottom) - Create an ellipse area CreatePolygonRgn (LPPoints , NumberOfPoints, Mode) - Create a polygonal area, these APIs return Combinergn (HDEST, HSOURCE1, HSOURE2, Combinemode) - Merge Area SetWindowRGN (HWND, HRGN, BREDRAW) - The method of the program is a scanning bit map Point, press in the row setting area and then merge into the total area.
