示例1: on_draw
# 需要導入模塊: from cairo import Context [as 別名]
# 或者: from cairo.Context import transform [as 別名]
def on_draw(self, widget: Widget, context: cairo.Context):
for child in self.list:
if child.visible:
context.save()
context.transform(child.fromWidgetCoords)
if child.is_clip_set():
rectangle = child.clip_rectangle
context.rectangle(rectangle.start.x,rectangle.start.y,
rectangle.width,rectangle.height)
context.clip()
child.on_draw(self,context)
context.restore()示例2: ImageSurface
# 需要導入模塊: from cairo import Context [as 別名]
# 或者: from cairo.Context import transform [as 別名]
