Implementation

pub fn pointToBodyRelative(self: *GridWidget, point: Point.Physical) ?Point {
    const scroll_wd = self.scroll.data();
    var result = scroll_wd.rectScale().pointFromPhysical(point);
    if (scroll_wd.rect.contains(result) and result.y >= self.header_height) {
        result.y -= self.header_height;
        return result;
    }
    return null;
}
