I want to set a shadow on several widgets using QGraphicsDropShadowEffect and I am wondering if there is a better way to do so without having to write the same code over and over again for every instance where I want to use it like in my example below. Is it possible to create a class or something to call so that I just have to set setGraphicsEffect()
on the widgets? I have tried to create a few classes for it but I was still only able to get them to create one shadow.
import sys
from PyQt5.QtWidgets import QWidget, QHBoxLayout, \
QGraphicsDropShadowEffect, QPushButton, QApplication, QComboBox
class MainWindow(QWidget):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
layout = QHBoxLayout()
self.shadow = QGraphicsDropShadowEffect()
self.shadow.setBlurRadius(5)
self.shadow.setXOffset(3)
self.shadow.setYOffset(3)
self.shadow2 = QGraphicsDropShadowEffect()
self.shadow2.setBlurRadius(5)
self.shadow2.setXOffset(3)
self.shadow2.setYOffset(3)
self.btn = QPushButton("Button")
self.btn.setGraphicsEffect(self.shadow)
self.combo = QComboBox()
self.combo.setGraphicsEffect(self.shadow2)
layout.addWidget(self.btn)
layout.addWidget(self.combo)
self.setLayout(layout)
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MainWindow()
w.show()
app.exec_()
The docs states that the same QGraphicsEffect can not be shared by other widgets:
So you will have to create a
QGraphicsEffect
for each widget, but if you do not want to write a lot of code and want to apply effects with similar characteristics you could iterate through the widgets and for that you can usefindChildren(...)
.
