PyQt5标签 – 为颜色效果设置颜色
在这篇文章中,我们将看到如何为标签的颜色效果设置颜色,在默认情况下,标签没有颜色效果,尽管我们可以为标签创建颜色效果。颜色效果并不像背景色,它更像我们在图片上使用的彩色滤镜。
语法: color_effect.setColor(color_object)
这里color_effect是QGraphicsColorizeEffect对象。
参数: 它以颜色对象为参数,例如Qt.green。
返回: 它返回无。
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__()
# 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)
# creating a color effect
color_effect = QGraphicsColorizeEffect()
# setting color to color effect
color_effect.setColor(Qt.darkGreen)
# adding color effect to the label
label.setGraphicsEffect(color_effect)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
