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。
In order to do this we will use unsetLayoutDirection method with the dock widget object.
Syntax : dock.unsetLayoutDirection()
Argument : It takes no argument
Return : It returns None
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())
输出 :
