Function gdk::error_trap_push

pub fn 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

⚠️ 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 ...
 }
