## Description

You can use this to hide and show groups of widgets all at once, without having to specify each one. They do not have to have the same parents, or even have the same toplevel window.

If a widget is destroyed before the group is, it will be automatically removed from the visibility group. You only ever need to free the XAppVisibilityGroup itself.

Only the specific members of the group have their visibility and sensitivity set, not their descendants. No effort is made to track or prevent state changes made to individual widgets by outside influence.

## Functions

### xapp_visibility_group_new ()

    XAppVisibilityGroup *
