[][src]Enum gtk::PolicyType

#[non_exhaustive]pub enum PolicyType {
    // some variants omitted

Determines how the size should be computed to achieve the one of the visibility mode for the scrollbars.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

The scrollbar is always visible. The view size is independent of the content.


The scrollbar will appear and disappear as necessary. For example, when all of a TreeView can not be seen.


The scrollbar should never appear. In this mode the content determines the size.


Don't show a scrollbar, but don't force the size to follow the content. This can be used e.g. to make multiple scrolled windows share a scrollbar. Since: 3.16
