I have a PyQt4 program that I froze using cx_freeze. The problem I am having is when I make a QGraphicsPixmapItem, which it is getting its' pixmap made from a SVG file, the Item gets made no problem, but the Pixmap doesn't load so there is no image just the item in the scene. The thing that confuses me is that this only happens when I am running it on a different computer than the one that built the exe. When I run the exe on the computer that built it the program works perfectly. Even when I try to run it on a computer with all the required python components and pyqt components installed on the computer, if it isn't the computer that built it, the pixmap is not loaded from the svg file. I am not sure if this is a problem with my cx_freeze setup.py file or if I need to change something in the main code so any help or just pointing me in the right direction will be great. My feeling is that something is getting messed up when cx_freeze is building it so I will paste the contents of my setup.py file below. Also I am running on Windows using Python v3.1.
from cx_Freeze import setup, Executable
files = ['drawings\\FULL', 'drawings\\PANEL', 'data.csv', 'panelData.csv']
binIncludes = ['C:\\Python31\\Lib\\site-packages\\PyQt4\\bin\\QtSvg4.dll']
includes = ['main', 'PunchDialog', 'ArrayDialog', 'PricingDialog', 'FontAndInputDialog', 'PanelSelector', 'PyQt4', 'os', 'sys', 'ctypes', 'csv']
packages = ['drawings']
path = ['C:\\Users\\Brock\\Documents\\Programming\\PanelDesigner\\DrawingFirst', 'C:\\Python31\\Lib', 'C:\\Python31\\Lib\\site-packages', 'C:\\Python31\\DLLs']
setup(
name = 'PanelBuilder',
version = '1.0',
description = 'Allows user to draw custom panel layouts.',
author = 'Brock Seabaugh',
options = {'build_exe': {'packages':packages, 'path':path, 'include_files':files, 'bin_includes':binIncludes, 'includes':includes}},
executables = [Executable('PanelBuilder.py')])
PS. Here is my file hierarchy(if that helps at all):
\DrawingFirst
Main .py file
All .py files for all custom dialogs used
\drawings
some modules used
\FULL
A bunch of SVG files used
\PANEL
More SVG files used
This is a nasty problem I have run into myself in the past. Let me quote http://www.py2exe.org/index.cgi/Py2exeAndPyQt: (I know you are using cx_freeze but I am sure you can adapt your script)
PyQt4 and image loading (JPG, GIF, etc)
PyQt4 uses plugins to read those image formats, so you'll need to copy the folder PyQt4\plugins\imageformats to appdir\imageformats. Like in the above cases, you can use data_files for this. This won't work with bundle_files on.
If the plugins are not reachable, then QPixmap.load/loadFromData will return False when loading an image in those formats.
testapp.py:
from PyQt4 import QtGui, QtSvg
import sys
app = QtGui.QApplication([])
wnd = QtSvg.QSvgWidget()
wnd.load("flower.svg")
wnd.show()
sys.exit(app.exec_())
setup.py:
from cx_Freeze import setup, Executable
files = ['flower.svg']
includes = ['sip', 'PyQt4.QtCore']
setup(
name = 'Example',
version = '1.337',
description = 'Allows user to see what I did there.',
author = 'something',
options = {'build_exe': {'include_files':files, 'includes':includes}},
executables = [Executable('testapp.py')])
I created this test app on a Windows 7 machine and copied it over to a Windows XP machine. I did not have to copy any dlls around - it worked just like that.
I've added a hook to cx_freeze that includes imageformats whenever PyQt4.QtGui is included in the original code. With imageformats in the right place, even the externally stored icons work.
For people coming here from Google: if you only use QtWebKit, you do need to copy the imageformats dir (which you find in PYTHONDIR\lib\site-packages\PyQt4\plugins) into your app dir. Specifying PyQt4.QtWebKit among the includes is not enough.
