PyQt5 QDockWidget – 获取样式表
在本文中,我们将了解如何获取 QDockWidget 的样式表。 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。样式表表示小部件的样式,即外观,它由颜色、间距、填充、边框特征组成。可以借助 setStyleSheet 方法进行设置。
In order to do this we will use styleSheet method with the dock widget object.
Syntax : dock.styleSheet()
Argument : It takes no argument
Return : It returns string
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 Title")
# 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 to the dock widget
dock.setGeometry(100, 0, 200, 30)
# setting style sheet to the dock widget
dock.setStyleSheet("QDockWidget"
"{"
"background : lightgreen;"
"}"
"QDockWidget::title"
"{"
"background : lightblue;"
"}"
"QDockWidget QPushButton"
"{"
"border : 2px solid black;"
"background : darkgreen;"
"}"
)
# getting style sheet
value = dock.styleSheet()
# setting text to the label
label.setText("Style Sheet : " + 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 :
