◆ 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(*)(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_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.
