PyQt5 QSpinBox – 为被按下的下降按钮添加边框
在这篇文章中,我们将看到如何在旋转盒子的向下按钮被按下时为它添加边框。Spinbox由上下两个按钮组成,向下按钮用于减去数值,它有自己的默认边框,尽管我们可以改变它。当下降按钮被按下时,一个自定义的边框将出现在下降按钮上。
为了做到这一点,我们必须改变与旋转框相关的样式表代码,下面是样式表代码
QSpinBox::down-button:pressed
{
border : 4px solid blue;
}
下面是实现的过程
# importing libraries

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 spin box
self.spin = QSpinBox(self)
# setting geometry to spin box
self.spin.setGeometry(100, 100, 250, 40)
# setting prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# setting style sheet to the spin box
# adding border to the down button of spin box
# when it get pressed
self.spin.setStyleSheet("QSpinBox::down-button:pressed"
"{"
"border : 4px solid red;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
