* @modifiers: Keyboard modifiers the event is setup with.
* @key_pressrelease: either %GDK_KEY_PRESS or %GDK_KEY_RELEASE
*
* This function is intended to be used in GTK+ test programs.
* If (@x,@y) are > (-1,-1), it will warp the mouse pointer to
* the given (@x,@y) corrdinates within @window and simulate a
* key press or release event.
*
* When the mouse pointer is warped to the target location, use
* of this function outside of test programs that run in their
* own virtual windowing system (e.g. Xvfb) is not recommended.
* If (@x,@y) are passed as (-1,-1), the mouse pointer will not
* be warped and @window origin will be used as mouse pointer
* location for the event.
*
* Also, gtk_test_simulate_key() is a fairly low level function,
* for most testing purposes, gtk_test_widget_send_key() is the
* right function to call which will generate a key press event
* followed by its accompanying key release event.
*
* Returns: wether all actions neccessary for a key event simulation
* were carried out successfully.

* Since: 2.14
