Initialising or releasing drawing resourcesΒΆ
BeginPaint() |
Initialise resources for drawing operations |
EndPaint() |
Release resources when draw operations completed |
SYNTAX
BeginPaint(window_id, start_xpos, start_ypos)
EndPaint(window_id)
All drawing operations, or sets of drawing operations, performed in a window must be enclosed between BeginPaint and EndPaint function calls. These functions initialise or release the resources needed to perform drawing operations in the current window.
The start_xpos and start_ypos parameters set the initial position for drawing operations, effectively calling the MoveTo() function for the co-ordinates specified.
Although it is not necessary to use BeginPaint and EndPaint when printing, it does no harm to include them.
EXAMPLE
BeginPaint(wintask,20,40)
... draw operations
EndPaint(wintask)
