CLASS

EW_Redraw - redraw description

SYNOPSIS

Class EW_Redraw is the object passed to widgets during their redraw phase.

PUBLIC MEMBER FUNCTIONS

void SetForce(long set)

long GetForce(void)
Set/Get the force flag. When set to non-zero, widgets will be forced to redraw, even if their dirtiness flag says it is not neccessary.

void SetMousePosition(long x,long y)

long GetMousePosition(long *x,long *y)
Set/Get the location of the mouse when the redraw was initiated.

void SetLimited(long set)

long GetLimited(void)
Set/Get the limited redraw flag. When set to non-zero, this indicates that the redraw is occuring through a limited exposure. One effect is that dirtyness flags are not cleared during the redraw, since areas outside the limited redraw may not actually get redrawn.
