Struct ViewSwitcherBar 

pub struct ViewSwitcherBar { /* private fields */ }

It's recommended to set [`policy`][struct@crate::ViewSwitcher#policy] to
[enum@Adw.ViewSwitcherPolicy.wide] in this case.

You may have to adjust the breakpoint condition for your specific pages.

This will be `NULL` if the widget is not contained in a root widget.

Readable


#### `scale-factor`

Readable


#### `sensitive`
 Whether the widget responds to input.

Readable | Writable


#### `tooltip-markup`
 Sets the text of tooltip to be the given string, which is marked up
with Pango markup.

Also see `Gtk::Tooltip::set_markup()`.

This is a convenience property which will take care of getting the
tooltip shown if the given string is not `NULL`:
[`has-tooltip`][struct@crate::gtk::Widget#has-tooltip] will automatically be set to true
and there will be taken care of [`query-tooltip`][struct@crate::gtk::Widget#query-tooltip] in
the default signal handler.
