PyQt5 - 在 QSpinBox 中获取颜色计数

在本文中，我们将了解如何获取旋转框的颜色计数，颜色计数基本上是旋转框可用的不同颜色的数量。存在多种颜色颜色计数，它们告诉您可以设置到旋转框的可能颜色编号。

为此，我们使用colorCount方法。

Syntax : spin_box.colorCount()

Argument : It takes no argument

Return : It returns integer i.e color count value of spin box

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 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, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # creating label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 70)
  
        # making it multi line label
        label.setWordWrap(True)
  
        # getting color count
        color_count = self.spin.colorCount()
  
        # setting to the label
        label.setText("Color Count : " + str(color_count))
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())

输出 ：
