PyQt5 QLabel - 检查颜色效果是否为窗口类型
在本文中,我们将了解如何检查标签的颜色效果是否为窗口类型。窗口类型允许用户知道颜色效果对象是否是窗口类型,就像主窗口或弹出窗口等一样。
为了检查颜色效果是否是小部件类型,我们使用isWindowType
方法。
Syntax : color_effect.isWindowType()
Argument : It takes no argument
Return : It returns bool
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__()
# making background color light yellow
self.setStyleSheet("background : lightyellow;")
# 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 label
label = QLabel("Label", self)
# setting geometry to the label
label.setGeometry(200, 100, 150, 60)
# setting alignment to the label
label.setAlignment(Qt.AlignCenter)
# setting font
label.setFont(QFont('Arial', 15))
# creating a color effect
self.color_effect = QGraphicsColorizeEffect()
# setting color to color effect
self.color_effect.setColor(Qt.darkBlue)
# adding color effect to the label
label.setGraphicsEffect(self.color_effect)
# creating result label
result = QLabel(self)
# setting geometry to the result
result.setGeometry(200, 200, 300, 30)
# checking if color effect is window type
check = self.color_effect.isWindowType()
# setting text to result label
result.setText("Window type ? : " + str(check))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
