Provided Methods§

Source

fn set_active(&self, index_: Option<u32>)

Sets the active item of self to be the item at index.

§index_

An index in the model passed during construction, or -1 to have no active item

Source

fn active(&self) -> Option<u32>

Returns the index of the currently active item, or -1 if there’s no active item. If the model is a non-flat treemodel, and the active item is not an immediate child of the root of the tree, this function returns gtk_tree_path_get_indices (path)[0], where path is the TreePath of the active item.

§Returns

An integer which is the index of the currently active item, or -1 if there’s no active item.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
