Function gdk::functions::error_trap_push [−][src]
pub fn error_trap_push()
Expand description
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
⚠️ The following code is in C ⚠️
gdk_error_trap_push ();
// ... Call the X function which may cause an error here ...
if (gdk_error_trap_pop ())
{
// ... Handle the error here ...
}
