SVG images dont appear after compiling PyQt4 pytho

Question

I wrote python application using svg images as icons.

QtGui.QIcon(':icons/icon.svg')  <- just like this

it works on my comuter but after compiling it with py2exe and running on another computer, theres no icons. if i try e.g. bmp format, all works fine. so i think it could be some library problem. I don't know what PyQt4 uses for svg graphics.

in setup.py file i wrote

dllList = ('mfc90.dll','msvcp90.dll','qtnetwork.pyd','qtxmlpatterns4.dll', 'qsvg4.dll', 'qsvgd4.dll')
origIsSystemDLL = py2exe.build_exe.isSystemDLL
def isSystemDLL(pathname):
    if os.path.basename(pathname).lower() in dllList:
        return 0
    return origIsSystemDLL(pathname)
py2exe.build_exe.isSystemDLL = isSystemDLL

setup(windows=[{"script" : "myApp.py"}], options={"py2exe" : {"includes" : ["sip", "PyQt4.QtNetwork", "PyQt4.QtWebKit", "PyQt4.QtSvg" ]}})

and also have imageformats folder (with qvg4.dll etc.) included in myApp.exe directory

so how solve this problem?

thanks, jarek

Answer 1

The qsvg plugin requires QtXml. Add "PyQt4.QtXml" to your includes.

Also see library dependencies in Qt.

Answer 2

You have to add a qt.conf in your application's main installation directory (actually, the application's working directory), containing:

[Paths]
Plugins = <directory containing the image plugins directory>

So the directory layout is:

• app.exe
• qt.conf
• plugins/
  • imageformats/
    • qsvg4.dll

And then in this case, the directory in qt.conf is plugins.

Answer 3

The plugin used (Qt 4.6) is:

• plugins/
  • iconengines/
    • qsvgicon4.dll

You still need qt.conf as Ivo explained.
