error_trap_push

This function allows X errors to be trapped instead of the normal behavior of exiting the application.

It should only be used if it is not possible to avoid the X error in any other way. Errors are ignored on all Display currently known to the DisplayManager . If you don’t care which error happens and just want to ignore everything, pop with error_trap_pop_ignored. If you need the error code, use error_trap_pop which may have to block and wait for the error to arrive from the X server.

This API exists on all platforms but only does anything on X.

You can use gdk_x11_display_error_trap_push to ignore errors on only a single display.

Trapping an X error

gdk_error_trap_push ();

 // ... Call the X function which may cause an error here ...


if (gdk_error_trap_pop ())
 {
	 // ... Handle the error here ...
 }
