PyQt5 QDockWidget – 获取标题栏部件

在这篇文章中，我们将看到如何获得QDockWidget的标题栏部件。QDockWidget提供了dock widget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中的二级窗口。标题栏部件是由标题和可用选项组成的部件，尽管我们可以在setTitleBarWidget方法的帮助下随时改变它。

为了做到这一点，我们将使用dock widget对象的titleBarWidget方法。

语法： dock.titleBarWidget()

参数： 它不需要参数

返回： 它返回QWidget对象

下面是实现

class Window(QMainWindow):
 
    def __init__(self):

        dock = QDockWidget(self)
 
        # setting title to the dock widget
        dock.setWindowTitle("                   GfG ")

        label.setGeometry(100, 200, 300, 80)
 
        # making label multi line
        label.setWordWrap(True)
 
        # setting geometry to the dock widget
        dock.setGeometry(100, 0, 200, 30)
 
        # creating a label
        widget = QLabel("Geeks", self)
 
        # setting title bar widget to the dock
        dock.setTitleBarWidget(widget)
 
        # getting title bar widget
        value = dock.titleBarWidget()
 
        # setting text to the label
        label.setText("Title Bar widget : " + str(value))
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
