PyQt5 QDockWidget – 为其设置小部件
在本文中,我们将看到如何将小部件设置为 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。停靠窗口可以在其当前区域内移动、移动到新区域并由最终用户浮动(例如,取消停靠)。
我们可以将小部件添加到停靠小部件,小部件可以是任何小部件,甚至可以是包含许多小子小部件的单个小部件。与停靠小部件一起,为其设置的小部件也随之移动。
In order to do this we will use setWidget
method with the dock widget object.
Syntax : dock.setWidget(widget)
Argument : It takes QWidget as argument
Return : It returns None
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)
# setting geometry tot he dock widget
dock.setGeometry(100, 0, 200, 30)
# 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)
# adding action to the push button
push.clicked.connect(lambda: label.setText("Dock Widget's Push button pressed"))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
