NAME

XSetGraphicsExposures — set the graphics_exposures component in a graphics context. 

SYNOPSIS

XSetGraphicsExposures(display, gc, graphics_exposures) Display ∗display;  GC gc;  Bool graphics_exposures;

ARGUMENTS

displaySpecifies a connection to an X server; returned from XOpenDisplay(). 

gcSpecifies the graphics context. 

graphics_exposures
Specifies whether you want GraphicsExpose and NoExpose events when calling XCopyArea() and XCopyPlane() with this graphics context. 

DESCRIPTION

XSetGraphicsExposure sets the graphics_exposures member of a GC.  If graphics_exposures is True, GraphicsExpose events will be generated when XCopyArea() and XCopyPlane() requests cannot be completely satisfied because a source region is obscured, and NoExpose events are generated when they can be completely satisfied.  If graphics_exposures is False, these events are not generated. 

These events are not selected in the normal way with XSelectInput().  Setting the graphics_exposures member of the GC used in the CopyArea or CopyPlane request is the only way to select these events. 

For more information, see Volume One, Chapter 5, The Graphics Context.
