PyQt5 QDockWidget – 设置布局方向

在这篇文章中，我们将看到如何为QDockWidget设置布局方向。QDockWidget提供了dock widget的概念，也被称为工具调色板或实用窗口。Dock窗口是放置在QMainWindow（原始窗口）中中央部件周围的dock部件区域的二级窗口。布局指定了子窗口的排列方式，通过设置布局方向我们可以指定排列的顺序。

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

语法： dock.setLayoutDirection(direct)

参数： 它需要方向对象作为参数

返回： 它返回无

下面是实现

# 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)
 
        # 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)
 
       
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
