PyQt5 QDockWidget - 取消布局方向

在本文中,我们将看到如何取消设置 QDockWidget 的布局方向。 QDockWidget 提供了停靠小部件的概念,也称为工具面板或实用程序窗口。停靠窗口是放置在 QMainWindow(原始窗口)中中央小部件周围的停靠小部件区域中的辅助窗口。布局指定孩子如何排列,通过设置布局方向我们可以指定排列的顺序,可以借助 setLayoutDirection 方法进行设置。取消设置意味着布局方向将恢复为默认值。

下面是实现

Python3
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
 
 
class Window(QMainWindow):
 
    def __init__(self):
        super().__init__()
 
        # setting title
        self.setWindowTitle("Python ")
 
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for components
    def UiComponents(self):
 
        # creating dock widget
        dock = QDockWidget(self)
 
        # setting title to the dock widget
        dock.setWindowTitle("                   GfG ")
 
 
        # push button
        push = QPushButton("Press", self)
 
        # setting widget to the dock
        dock.setWidget(push)
 
        # setting layout direction
        dock.setLayoutDirection(Qt.RightToLeft)
 
        # unsetting layout direction
        dock.unsetLayoutDirection()
 
        # creating a label
        label = QLabel("GfG", self)
 
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)
 
        # making label multi line
        label.setWordWrap(True)
 
        # setting geometry tot he dock widget
        dock.setGeometry(100, 0, 200, 30)
 
        # getting layout direction of dock
        value = dock.layoutDirection()
 
        # setting text to the label
        label.setText("Layout Direction : " + str(value))
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
