I'm reading a tutorial on PySide and I was thinking , do I need to find my own icons for every thing or is there some way to use some built in icons . That way I wouldn't need to find an entire new set of icons if I want my little gui to run on another desktop environment .

What you need is Pyside QIcon.fromTheme function. Basicaly it creates QIcon object with needed icon from current system theme.
Usage:
undoicon = QIcon.fromTheme("edit-undo")
"edit undo" - name of the icon "type"/"function" can be found here
This works on X11 systems, for MacOSX and Windows check QIcon documentation QIcon.fromTheme
Edit Inserting this from the website, since last time it was a broken link.
static PySide.QtGui.QIcon.fromTheme(name[, fallback=QIcon()])
Parameters:
- name
- fallbackPySide.QtGui.QIcon
Return type:
Returns the PySide.QtGui.QIcon corresponding to name in the current icon theme. If no such icon is found in the current theme fallback is returned instead.
The latest version of the freedesktop icon specification and naming specification can be obtained here:
- http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html
- http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html
To fetch an icon from the current icon theme:
undoicon = QIcon.fromTheme("edit-undo")Or if you want to provide a guaranteed fallback for platforms that do not support theme icons, you can use the second argument:
undoicon = QIcon.fromTheme("edit-undo", QIcon(":/undo.png"))Note
By default, only X11 will support themed icons. In order to use themed icons on Mac and Windows, you will have to bundle a compliant theme in one of your PySide.QtGui.QIcon.themeSearchPaths() and set the appropriate PySide.QtGui.QIcon.themeName() .

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

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:

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...
回答5:
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.

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)
