| drag_begin_for_device |
Starts a drag and creates a new drag context for it. |
| drag_begin_from_point |
Starts a drag and creates a new drag context for it. since: 3.20 |

| drag_drop_done |
Inform GDK if the drop ended successfully. Passing FALSEfor success may trigger a drag cancellation animation. since: 3.20 |

| error_trap_pop |
Removes an error trap pushed with gdk_error_trap_push(). May block until an error has been definitively received or not received from the X server. gdk_error_trap_pop_ignored()is preferred if you don’t need to know whether an error occurred, because it never has to block. If you don’t need the return value of gdk_error_trap_pop(), use gdk_error_trap_pop_ignored(). |
| error_trap_pop_ignored |
Removes an error trap pushed with gdk_error_trap_push(), but without bothering to wait and see whether an error occurred. If an error arrives later asynchronously that was triggered while the trap was pushed, that error will be ignored. since: 3.0 |
| 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 GdkDisplay currently known to theGdkDisplayManager. If you don’t care which error happens and just want to ignore everything, pop with gdk_error_trap_pop_ignored(). If you need the error code, use gdk_error_trap_pop() which may have to block and wait for the error to arrive from the X server. |

| threads_add_timeout_full |
Sets a function to be called at regular intervals holding the GDK lock, with the given priority.
