Opens a display. Since: 2.2
|
|
Opens the default display specified by command line arguments or environment variables, sets it as the default display, and returns it. gdk_parse_args must have been called first. If the default display has previously been set, simply returns that. An internal function that should not be used by applications.

Gets a copy of the first Gdk::Event in the display 's event queue, without removing the event from the queue. (Note that this function will not get more events from the windowing system. It only checks the events that have already been moved to the GDK event queue.)
|

|
|
This function allows for hooking into the operation of getting the current location of the pointer on a particular display. This is only useful for such low-level tools as an event recorder. Applications should never have any reason to use this facility.

|
|
Flushes any requests queued for the windowing system and waits until all requests have been handled. This is often used for making sure that the display is synchronized with the current state of the program. Calling sync() before gdk_error_trap_pop() makes sure that any errors generated from earlier requests are handled before the error trap is removed. This is most useful for X11. On windowing systems where requests are handled synchronously, this function will do nothing. Since: 2.2 |
