[SOLVED]can i set the percent of fill while keep the outline static while use a custom QGraphicsPolygonItem ?
i inherite a class from QGraphicsPolygonItem.
i now want to keep the outline static, meanwhile, i want to make the fill content dynamically changed.
eg. the fill color is only the half height, while the outline color is still there.
and i found that there can be only 1 QPolygonF in the class.
Either creator your own QGraphicsItem and implement paint as you need it, or create two items: One for the outline, one for the fill area.
ok, got it
