}

A GUI event delivered to a widget.

Coordinate positions are in the local coordinate space of the widget receiving the event (bottom-left origin, Y-up). The framework translates positions as it descends the widget tree.

Variants

MouseMove

The cursor moved to pos (may be outside widget bounds — used to clear hover state).

Fields

MouseWheel

Mouse wheel scrolled. delta_y is in logical pixels; positive = scroll up (content moves up, typical “natural” scroll direction). delta_x is horizontal wheel / trackpad input in the same units; positive = content moves right. pos is the cursor location at the time of the scroll.

Fields

pos: Point

delta_y: f64

delta_x: f64
