Struct egui::layers::PaintList[−][src]

Returns the index of the new Shape that can be used with PaintList::set.

Modify an existing Shape.

Sometimes you want to paint a frame behind some contents, but don’t know how large the frame needs to be until the contents have been added, and therefor also painted to the PaintList.

The solution is to allocate a Shape using let idx = paint_list.add(cr, Shape::Noop); and then later setting it using paint_list.set(idx, cr, frame);.

Translate each Shape and clip rectangle by this much, in-place
