Enum gtk::PolicyType
source · [−]#[non_exhaustive]
pub enum PolicyType {
Always,
Automatic,
Never,
External,
// some variants omitted
}
Expand description
Determines how the size should be computed to achieve the one of the visibility mode for the scrollbars.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Always
The scrollbar is always visible. The view size is independent of the content.
Automatic
The scrollbar will appear and disappear as necessary.
For example, when all of a TreeView
can not be seen.
Never
The scrollbar should never appear. In this mode the content determines the size.
External
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
