Using a .SVG as the image for a button in PyQt5 and Qt Designer
I'm trying to use an .SVG as the image for a button in PyQt5, however it seems this is only supported in PyQt6 (tried and worked great, but PyQt6 doesn't support other things, like QtCore.Qt.AA_EnableHighDpiScaling, so I can't switch).
I've tried importing only the QIcon from PyQt6 but naturally this doesn't work.
It doesn't have to be on a button, as long as I can call a function from it with clicked.connect()
I'm aware of the QSvgWidget class but there doesn't appear to be a clear way to use/add this in QtDesigner. The buttons in question are embedded within a few layouts with spacers so adding in the QSvgWidget without designer wouldn't work either.
Is there a way for me to add a widget in Qt Designer, add an .SVG to it, and call a function from it when clicked? I am trying to get DpiScaling to work across multiple scaled monitors and the .SVG icons scale way nicer than .PNG.
Example code only runs with a .ui from designer, but illustrates the desired outcome.
from PyQt5 import QtWidgets, uic, QtCore, QtGui
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
import sys
class MainWindow(QtWidgets.QMainWindow):
def __init__(self):
super(MainWindow, self).__init__()
#Need the widget to be in the .ui file from Qt Designer
uic.loadUi("assets/mainwindow.ui", self)
#QPushButton - it doesn't have to be this class as long as I can use a .SVG on it and call a function on click
self.svg_button.setIcon(QtGui.QIcon('assets/copy.svg'))
self.svg_button.setIconSize(QtCore.QSize(25,25))
self.svg_button.clicked.connect(self.something)
def something(self):
print('i have an svg icon, woohoo')
def main():
app = QtWidgets.QApplication([sys.argv])
window = MainWindow()
window.show()
sys.exit(app.exec())
if __name__ == '__main__':
main()
