Controls how important event sources are during the main loop.
|-100||Gobject::PRIORITY_DEFAULT||Use this for default priority event sources|
|100||Gobject::PRIORITY_HIGH_IDLE||Use this for high priority timeouts. This priority is never used inside GTK+ so everything running at this priority will be running before anything inside the toolkit.|
|110||Gobject::PRIORITY_HIGH_IDLE||Use this priority for resizing related stuff. It is used internally by GTK+ to compute the sizes of widgets. This priority is higher than Gobject::GTK_PRIORITYto avoid resizing a widget which was just redrawn.|
|120||Gobject::PRIORITY_REDRAW||Use this priority for redrawing related stuff. It is used internally by GTK+ to do pending redraws. This priority is lower than Gobject::PRIORITY_RESIZE to avoid redrawing a widget just before resizing (and therefore redrawing it again).|
|200||Gobject::PRIORITY_DEFAULT_IDLE||Default priority for idle functions.|
|300||Gobject::PRIORITY_LOW||Priority for very unimportant background tasks.|
