PyQt5 QDockWidget – 设置布局

在本文中，我们将看到如何将布局设置为 QDockWidget。 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。布局指定内部组件的排列方式。

In order to do this we will use setLayout method with the dock widget object.
Syntax : dock.setLayout(layout)
Argument : It takes QLayout object as argument
Return : It returns None

编程需要懂一点英语

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 Dock")
 
 
        # push button
        push = QPushButton("Press", self)
 
        # setting widget to the dock
        dock.setWidget(push)
 
        # creating a label
        label = QLabel("GeeksforGeeks", 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)
 
        # creating a vertical layout
        layout = QVBoxLayout(self)
 
        # setting layout to the dock
        dock.setLayout(layout)
 
      
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
