Interface QDDrawer
- public interface QDDrawer
This interface is used in conjunction with the QDGraphics.beginDraw method
to perform a collection of drawing operations in a single call. This is important
for efficient drawing as global thread state that is required for each of the
rendering methods on the QDGraphics class can be established once in the beginDraw
method. Thus when this interface's draw method is called, this global state does not
have to be reestablished before each drawing operation is performed.
