#### Functions

###### gdk_x11_display_open

Tries to open a new display to the X server given by `display_name`. If opening the display fails, `NULL` is returned.

###### gdk_x11_display_set_program_class

Sets the program class.

#### Instance methods

###### gdk_x11_display_broadcast_startup_message

Sends a startup notification message of type `message_type` to `display`.

###### gdk_x11_display_error_trap_pop

Pops the error trap pushed by gdk_x11_display_error_trap_push(). Will XSync() if necessary and will always block until the error is known to have occurred or not occurred, so the error code can be returned.

###### gdk_x11_display_error_trap_pop_ignored

Pops the error trap pushed by gdk_x11_display_error_trap_push(). Does not block to see if an error occurred; merely records the range of requests to ignore errors for, and ignores those errors if they arrive asynchronously.

###### gdk_x11_display_error_trap_push

Begins a range of X requests on `display` for which X error events will be ignored. Unignored errors (when no trap is pushed) will abort the application. Use `gdk_x11_display_error_trap_pop()` or gdk_x11_display_error_trap_pop_ignored()to lift a trap pushed with this function.

###### gdk_x11_display_get_default_group

Returns the default group leader surface for all toplevel surfaces on `display`. This surface is implicitly created by GDK. See gdk_x11_surface_set_group().
