Enum DisplayItem 

pub enum DisplayItem {
    Op(PaintOp),
    PushClip(Rect),
    PopClip,
    PushOffset(Point),
    PopOffset,
}

One entry in a DisplayList.

Variants

Op(PaintOp)

A drawing operation.

PushClip(Rect)

Clips every following item to this rectangle until the matching DisplayItem::PopClip.

PopClip

Restores the clip that was active before the matching DisplayItem::PushClip.

PushOffset(Point)

Draws every following item translated by this offset until the matching DisplayItem::PopOffset.

Offsets nest with clips and with each other: an item’s window position is its own position plus the sum of the open offsets. Clips pushed inside an offset scope hold their rectangle in the scope’s coordinates, so translating the scope moves the clip with the items it cuts.

PopOffset

Restores the offset that was active before the matching DisplayItem::PushOffset.
