PyQt5 QDockWidget – 获取允许的区域

在本文中，我们将了解如何获取 QDockWidget 的允许区域。 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。 Dock 可以在主窗口中的任何位置移动，设置可以放置 Dock 小部件的允许区域，可以借助setAllowedAreas方法进行设置。

In order to do this we will use allowedAreas method with the dock widget object.

Syntax : dock.allowedAreas()

Argument : It takes no argument

Return : It returns QDockWidgetArea object

编程需要懂一点英语

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("GeeksforGeeks", self)
  
        # 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)
  
  
        # getting allowed areas of the dock
        value = dock.allowedAreas()
  
        # setting text to the label
        label.setText("Allowed Areas : " + str(value))
  
  
  
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
