Struct egui::hit_test::WidgetHits

pub struct WidgetHits {
    pub contains_pointer: Vec<WidgetRect>,
    pub click: Option<WidgetRect>,
    pub drag: Option<WidgetRect>,
}

Result of a hit-test against WidgetRects.

Answers the question “what is under the mouse pointer?”.

Note that this doesn’t care if the mouse button is pressed or not, or if we’re currently already dragging something.

Fields

contains_pointer: Vec<WidgetRect>

All widgets that contains the pointer, back-to-front.

i.e. both a Window and the button in it can contain the pointer.

Some of these may be widgets in a layer below the top-most layer.

click: Option<WidgetRect>

If the user would start a clicking now, this is what would be clicked.

This is the top one under the pointer, or closest one of the top-most.

drag: Option<WidgetRect>

If the user would start a dragging now, this is what would be dragged.

This is the top one under the pointer, or closest one of the top-most.
