Enum gtk4::TreeViewColumnSizing

#[non_exhaustive]
pub enum TreeViewColumnSizing {
    GrowOnly,
    Autosize,
    Fixed,
}

The sizing method the column uses to determine its width. Please note that Autosize are inefficient for large views, and can make columns appear choppy.

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.

GrowOnly

Columns only get bigger in reaction to changes in the model

Autosize

Columns resize to be the optimal size every time the model changes.

Fixed

Columns are a fixed numbers of pixels wide.
