PyQt5 QColorDialog – 检查大小夹属性是否启用

在本文中，我们将了解如何检查 QColorDialog 的尺寸夹点属性是否启用。启用此属性时，QSizeGrip 将放置在对话框的右下角。默认情况下，尺寸夹点处于禁用状态。我们可以借助setSizeGripEnabled方法设置此属性。

为了做到这一点，我们使用isSizeGripEnabled方法和 QColorDialog 对象

Syntax : dialog.isSizeGripEnabled()

Argument : It takes no argument

Return : It returns None

下面是实现

# importing libraries

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 a QColorDialog object
        dialog = QColorDialog(self)
  
        # setting custom colors
        dialog.setCustomColor(1, Qt.red)
        dialog.setCustomColor(2, Qt.green)
        dialog.setCustomColor(3, Qt.yellow)
        dialog.setCustomColor(4, Qt.blue)
  
        # setting grip size property enabled
        dialog.setSizeGripEnabled(True)
  
        # creating label
        label = QLabel("Geeks for Geeks", self)
  
        label.setAlignment(Qt.AlignCenter)
  
        # making label multi line
        label.setWordWrap(True)
  
        # setting stylesheet of the label
        label.setStyleSheet("QLabel"
                            "{"
                            "border : 5px solid black;"
                            "}")
  
  
        # getting the custom color
        color = dialog.customColor(4)
  
        # setting graphic effect to the label
        graphic = QGraphicsColorizeEffect(self)
  
        # setting color to the graphic
        graphic.setColor(color)
  
        # setting graphic to the label
        label.setGraphicsEffect(graphic)
  
        layout = dialog.layout()
  
        layout.addWidget(label)
  
        dialog.setLayout(layout)
  
        # checking size grip enabled
        value = dialog.isSizeGripEnabled()
  
        # setting text to the label
        label.setText("Size Grip Enabled : " + str(value))
  
        dialog.exec_()
  
        self.deleteLater()
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
