PyQt5 - 中间复选框的背景颜色
在本文中,我们将看到如何在复选框处于中间状态时为复选框(即标签部分)设置颜色。我们可以为复选框设置背景颜色,但对于所有状态都将保持不变。中间状态是介于已检查和未检查状态之间的状态状态,它是借助setTristate
方法创建的第三种状态。
为了设置中间状态的背景颜色,我们必须更改处于不确定(中间)状态的标签部分的样式表。下面是样式表代码。
QCheckBox::indeterminate
{
background-color : cyan;
}
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, 600, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating the check-box
checkbox = QCheckBox('Geek ?', self)
# setting tristate check box
checkbox.setTristate(True)
# setting geometry of check box
checkbox.setGeometry(200, 150, 100, 30)
# adding background color to the pressed check box label part
# when it is in intermediate state
checkbox.setStyleSheet("QCheckBox:indeterminate"
"{"
"background-color : cyan;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
