QGraphicsPolygonItem ¶

概要 ¶

详细描述 ¶

PySide.QtGui.QGraphicsPolygonItem class provides a polygon item that you can add to a PySide.QtGui.QGraphicsScene .

To set the item's polygon, pass a PySide.QtGui.QPolygonF to PySide.QtGui.QGraphicsPolygonItem ‘s constructor, or call the PySide.QtGui.QGraphicsPolygonItem.setPolygon() function. The PySide.QtGui.QGraphicsPolygonItem.polygon() function returns the current polygon.

PySide.QtGui.QGraphicsPolygonItem uses the polygon and the pen width to provide a reasonable implementation of PySide.QtGui.QGraphicsPolygonItem.boundingRect() , PySide.QtGui.QGraphicsPolygonItem.shape() ，和 PySide.QtGui.QGraphicsPolygonItem.contains() 。 PySide.QtGui.QGraphicsPolygonItem.paint() function draws the polygon using the item's associated pen and brush, which you can set by calling the PySide.QtGui.QAbstractGraphicsShapeItem.setPen() and PySide.QtGui.QAbstractGraphicsShapeItem.setBrush() 函数。
