Are there default icons in PyQt/PySide?

I don’t think this is specific to any binding, you can check the qt general documentation

take a look here and here

in PyQt, the window icon is by default the Qt logo. I think you will have to find your own icons for things inside the gui.

There is another way to access some of the standard builtin icons in PyQt/PySide using the standard pixmap in the default style. For example, the following creates an icon for opening a file:

self.style().standardIcon(QtGui.QStyle.SP_DialogOpenButton)

For the full list of standard pixmaps, see:

http://srinikom.github.io/pyside-docs/PySide/QtGui/QStyle.html#PySide.QtGui.PySide.QtGui.QStyle.StandardPixmap

I keep having trouble finding images of the standard icons, so for future reference: http://nukesaq88.hatenablog.com/entry/2013/04/12/005525

And the code I’m using (PyQt4, Pyside probably similar):

    # In method of QMainWindow subclass
    stdicon = self.style().standardIcon
    style = QtGui.QStyle
    reload_foo = QtGui.QAction(stdicon(style.SP_BrowserReload), '&Reload', self)

It would be nice if the (obviously auto-generated) Qt docs had pictures in the standardIcons enum table…

In PyQt5, here’s a simple example of creating a push button with the play icon:

play_button = QtGui.QPushButton('Play video')
play_button.setIcon(QtGui.QApplication.style().standardIcon(QtGui.QStyle.SP_MediaPlay))

The Qt5 documentation provides a list of the possible SP (“Standard Pixmap”) icons. See enum QStyle::StandardPixmap here: http://doc.qt.io/qt-5/qstyle.html

Another PyQt5 example using the standard icons (eqzx‘s answer didn’t work for me):

 from PyQt5.QtWidgets import QApplication, QStyle
 from PyQt5.QtGui import QIcon

 desktop_icon = QIcon(QApplication.style().standardIcon(QStyle.SP_DesktopIcon)

A PyQt5 example that will display all built-in icons (the list is from the QStyle docs).

from PyQt5.QtWidgets import (QApplication, QGridLayout, QPushButton, QStyle, QWidget)

class Window(QWidget):
    def __init__(self):
        super(Window, self).__init__()
