Icons not displaying in QToolBar

ptrs32

Hello,

I'm a beginner on PyQt5 and i'm trying to display my first window with a toolBar and an icon inside. In the Qt Designer i just add a QtAction with an icon and it is visible correclty there but when i lauch the script the icon is not displayed, only the button text.

MainWindow class :

class Ui_mainWindow(object):
    def setupUi(self, mainWindow):
        mainWindow.setObjectName("mainWindow")
        mainWindow.resize(800, 600)
        mainWindow.setMinimumSize(QtCore.QSize(800, 600))
        mainWindow.setCursor(QtGui.QCursor(QtCore.Qt.ArrowCursor))
        mainWindow.setMouseTracking(False)
        mainWindow.setToolButtonStyle(QtCore.Qt.ToolButtonTextBesideIcon)
        self.centralwidget = QtWidgets.QWidget(mainWindow)
        self.centralwidget.setObjectName("centralwidget")
        mainWindow.setCentralWidget(self.centralwidget)
        self.toolBar = QtWidgets.QToolBar(mainWindow)
        self.toolBar.setMovable(False)
        self.toolBar.setAllowedAreas(QtCore.Qt.AllToolBarAreas)
        self.toolBar.setIconSize(QtCore.QSize(30, 30))
        self.toolBar.setToolButtonStyle(QtCore.Qt.ToolButtonTextUnderIcon)
        self.toolBar.setFloatable(True)
        self.toolBar.setObjectName("toolBar")
        mainWindow.addToolBar(QtCore.Qt.LeftToolBarArea, self.toolBar)
        self.actionNewFile = QtWidgets.QAction(mainWindow)
        icon = QtGui.QIcon()
        icon.addPixmap(QtGui.QPixmap("ressources/icons/download.png"), QtGui.QIcon.Normal, QtGui.QIcon.Off)
        self.actionNewFile.setIcon(icon)
        self.actionNewFile.setShortcutContext(QtCore.Qt.WidgetShortcut)
        self.actionNewFile.setVisible(True)
        self.actionNewFile.setShortcutVisibleInContextMenu(True)
        self.actionNewFile.setObjectName("actionNewFile")
        self.toolBar.addAction(self.actionNewFile)

        self.retranslateUi(mainWindow)
        QtCore.QMetaObject.connectSlotsByName(mainWindow)

Main script :

import sys
from PyQt5 import QtWidgets

from form import Ui_mainWindow


class ExampleApp(QtWidgets.QMainWindow, Ui_mainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        
def main():
    app = QtWidgets.QApplication(sys.argv)
    window = ExampleApp()
    window.show()
    app.exec_()

if __name__ == '__main__':
    main()

Repositories architecture :

QTProject\
_form.py
_main.py
_ressources\
__icons\
___download.png

Thank you for your help.

@ptrs32 said in Icons not displaying in QToolBar:

icon.addPixmap(QtGui.QPixmap("ressources/icons/download.png")

One thought: that is a relative path. It will be sought relative to whatever the current/working directory when you run the Python script. I don't know what that might be for you, depending on how you run it from where?

You can test something like

pixmap = QtGui.QPixmap("ressources/icons/download.png")
print(pixmap.isNull())

or similar to verify whether that file was read in.

I assume ressources is correct name for you, because it's a misspelling of resources. That's OK so long as it is what you have. You could also try something like

open("ressources/icons/download.png", "rb")

in Python to see whether the file path is found/can be opened, independent of whether it works as a pixmap.

@JonB Ok i found the problem. I renamed the "ressources" repository in "resources" and it works... I didn't know the name of this repository was really important as long as my paths was correct, but apparently yes.

So thank you and have a good day :)
