PyQt5 QDockWidget – 设置图形效果对象
在这篇文章中,我们将看到如何为QDockWidget设置图形效果对象。QDockWidget提供了dock widgets的概念,也被称为工具调色板或实用窗口。停靠窗口是放置在QMainWindow(原始窗口)中中央部件周围的停靠部件区域的二级窗口。图形效果可以是阴影、模糊、颜色甚至是自定义的效果,它被用来使停靠窗口具有吸引力。
为了做到这一点,我们将使用dock widget对象的setGraphicsEffect方法。
语法: dock.setGraphicsEffect(effect)
参数: 它需要QGraphicEffect对象作为参数
返回: 它返回无
下面是实现

# color effect
color = QGraphicsColorizeEffect(self)
# setting green color to the effect
color.setColor(Qt.darkGreen)
# setting graphic effect to the dock
dock.setGraphicsEffect(color)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
