PyQt5 QSpinBox – 添加皮肤

PyQt5 QSpinBox – 添加皮肤

在这篇文章中,我们将看到如何为旋转框的各种状态设置皮肤。基本上,旋转盒有三种状态,一种是正常状态,第二种是悬停状态,即光标在旋转盒上时,第三种是按下状态,即鼠标按钮被按下时。皮肤基本上是一个背景图像,它可以根据旋转框的大小来调整自己。

为了做到这一点,我们必须改变与旋转盒相关的样式表,下面是样式表的代码

QSpinBox
{
border-image : url(image1.png);
}
QSpinBox::hover
{
border-image : url(image2.png);
}
QSpinBox::pressed
{
border-image : url(image3.png);
}

这将为每个状态添加三种不同的皮肤,还有一些额外的状态,如anti-hover(!hover)和anti-pressed(!pressed)这些分别是与hover和pressed状态相反的。

下面是实现方法

# 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 spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting range to the spin box
        self.spin.setRange(0, 9999)
  
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
  
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
  
        # setting style sheet
        # adding skin to spin box
        # adding skin for hover and pressed state
        self.spin.setStyleSheet("QSpinBox"
                                "{"
                                "border-image : url(image.png);"
                                "}"
                                "QSpinBox::hover"
                                "{"
                                "border-image : url(skin.png);"
                                "}"
                                "QSpinBox::pressed"
                                "{"
                                "border-image : url(logo.png);"
                                "}"
                                )
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
