CreateCaret is a Boolean function used to created the caret (or text cursor) displayed on a control when editing is active. CreateCaret calls the corresponding routine in the widgetset class to initialize the cursor with a given size, or a shape loaded from a bitmap image.
Handle is the HWND value representing the handle for the windowed control which owns and implements the caret.
Bitmap is the HBITMAP value with the handle for the bitmap image used as the caret shape. When Bitmap is set to 0, a handle is not available for the caret shape. When Bitmap is assigned, the values in the Height and Width arguments are ignored; the dimensions are determined by the bitmap image.
The Windows platform attaches special meanings to the values 0 and 1 in the Bitmap handle. 0 causes a solid black block with the dimensions in Height and Width to be used as the caret shape. 1 causes a solid gray block with the dimensions in Height and Width to be used as the caret shape.
