Struct WidgetState

Source

pub struct WidgetState { /* private fields */ }

Expand description

Generic state for all widgets in the hierarchy.

This struct contains the widget’s layout rect, flags indicating when the widget is active or focused, and other state necessary for the widget to participate in event flow.

It is provided to paint calls as a non-mutable reference, largely so a widget can know its size, also because active and focus state can affect the widget’s appearance. Other than that, widgets will generally not interact with it directly, but it is an important part of the WidgetPod struct.
