Struct winsafe::gui::events::TreeViewEvents

pub struct TreeViewEvents(/* private fields */);

Available on crate feature gui only.

Exposes tree view control notifications.

These event methods are just proxies to the WindowEvents of the parent window, who is the real responsible for the child event handling.

You cannot directly instantiate this object, it is created internally by the control.
