Controls how important event sources are during the main loop.
Value | Symbolic name | Description |
| -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. |
