PyQt5标签 – 添加颜色效果
在这篇文章中,我们将看到如何为标签添加颜色效果,默认情况下,标签是没有颜色效果的,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,下面是带有颜色效果的标签的表示方法:
。
为了做到这一点,我们必须做到以下几点 –
1.创建一个标签
2.为标签设置几何图形
3.创建一个QGraphicsColorizeEffect对象
4.在setGraphicsEffect方法的帮助下,把这个对象添加到标签中。
语法:
# creating a color effect
color_effect = QGraphicsColorizeEffect()
# adding color effect to the label
label.setGraphicsEffect(color_effect)
以下是实施情况
# 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 cyan
self.setStyleSheet("background : cyan;")
# 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()
# 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())
输出 :
