PyQt5 QDockWidget - 检查它是否有垂直标题栏
在本文中,我们将看到如何检查 QDockWidget 的垂直标题栏。 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。默认情况下,标题栏是水平的,尽管我们可以随时借助 dock.setFeatures(QDockWidget.DockWidgetVerticalTitleBar) 命令使其垂直。
In order to do this we will use features method with the dock widget object.
Syntax : dock.features()
Argument : It takes no argument
Return : It returns feature object which is checked with the vertical feature object
下面是实现
Python3
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui 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 Title")
# setting vertical title bar
dock.setFeatures(QDockWidget.DockWidgetVerticalTitleBar)
# creating a QWidget object
widget = QWidget(self)
# creating a vertical box layout
layout = QVBoxLayout(self)
# push button 1
push1 = QPushButton("A", self)
# push button 2
push2 = QPushButton("B", self)
# adding these buttons to the layout
layout.addWidget(push1)
layout.addWidget(push2)
# setting the layout to the widget
widget.setLayout(layout)
# adding widget to the layout
dock.setWidget(widget)
# creating a label
label = QLabel("GeesforGeeks", 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 features
feature = dock.features()
# checking if vertical feature
value = feature == QDockWidget.DockWidgetVerticalTitleBar
# setting text to the label
label.setText("Vertical Title bar : " + 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 :
