Struct druid::ViewContext

pub struct ViewContext {
    pub window_origin: Point,
    pub last_mouse_position: Option<Point>,
    pub clip: Rect,
}

Information about the widget’s surroundings.

The global origin is also saved in the widget state.

When the ViewContext of a widget changes it receives a ViewContextChanged event.

last_mouse_position: Option<Point>

The last position the cursor was at, relative to the widget.

clip: Rect
