Widget.queueDrawArea
void queueDrawArea(int x, int y, int width, int height)Convenience function that calls gtk.widget.Widget.queueDrawRegion on the region created from the given coordinates.
The region here is specified in widget coordinates. Widget coordinates are a bit odd; for historical reasons, they are defined as widget->window coordinates for widgets that return true for gtk.widget.Widget.getHasWindow, and are relative to widget->allocation.x, widget->allocation.y otherwise.
width or height may be 0, in this case this function does nothing. Negative values for width and height are not allowed.
Parameters
x | x coordinate of upper-left corner of rectangle to redraw |
y | y coordinate of upper-left corner of rectangle to redraw |
width | width of region to draw |
height | height of region to draw |
