Place an empty monochrome bitmap in the hbmMask field, and then place the alpha blended DIB section in the hbmColor field.Use the bitmap and alpha information that you want for your alpha blended cursor or icon to complete the DIB section.Call the CreateDIBSection function to create a DIB section based on the BITMAPV5HEADER structure that you completed.Complete a BITMAPV5HEADER structure, as in the code example following these steps, to define a 32 bits per pixel (BPP) alpha blended DIB.
AND maskįollow these steps to create an alpha blended cursor or icon at run time: To create the cursor, CreateCursor applies the following truth table to the AND and XOR masks. HINSTANCE hinst // handle to current instance The example is included here to illustrate how the system interprets cursor masks. The following example uses the CreateCursor function to create a custom monochrome cursor at run time. Using cursor resources avoids device dependence, simplifies localization, and enables applications to share cursor designs. HCurs2 = LoadCursor(hinst, MAKEINTRESOURCE(240)) Īpplications should implement custom cursors as resources and use LoadCursor, LoadCursorFromFile, or LoadImage rather than create the cursor at run time. Create a custom cursor based on a resource. The following example creates two cursor handles: one for the standard hourglass cursor and one for a custom cursor included as a resource in the application's resource-definition file. Using Cursor Functions to Create a Mousetrap.This section discusses the following topics.
