fl_window_monitor_new()

G_MODULE_EXPORT FlWindowMonitor * fl_window_monitor_new	(	GtkWindow *	window,
		void(*)(void)	on_configure,
		void(*)(void)	on_state_changed,
		void(*)(void)	on_is_active_notify,
		void(*)(void)	on_title_notify,
		void(*)(int, int, int, int)	on_moved_to_rect,
		void(*)(void)	on_close,
		void(*)(void)	on_destroy
	)

fl_window_monitor_new: @window: the window being monitored. @on_configure: the function to call when the window changes size, position or stacking. @on_state_changed: the function to call when the window state changes. @on_is_active_notify: the function to call when the is-active property changes. @on_moved_to_rect: the function to call when a popup window is moved to a new position. @on_close: the function to call when the user requests the window to be closed. @on_destroy: the function to call when the window is destroyed.

Helper class to allow the Flutter engine to monitor a GtkWindow using FFI. Callbacks are called in the isolate this class was created with.

Returns: a new #FlWindowMonitor.
