PYQT4 - How do I compile and import a qrc file into my program?

Question

I'm having trouble importing a resource file. I'm using pyqt4 with monkey studio and I am trying to import a png image. When I run the program I get an import error like

ImportError: No module named icon_rc

I know that I have to compile it using pyrcc4 but I don't understand how to do this can anybody help please. It would be very helpful to have an answer that fully explains how to compile the resource file so I can import it.

Open cmd (or terminal on *nix) and run

pyrcc4 -py3 F:\computing\Payrollv22\icon.qrc -o icon_rc.py

It compiled the file successfully and I was able to import the py file into my project and run it with no problem.

It may be worth pointing out that the `-py3` switch is only required if you are using Python 3.x. If you are using Python 2.x, the resource file needs to be compiled without this additional switch. – 0x8BADF00D Feb 19 '15 at 12:31

@0x8BADF00D [According to the docs](http://pyqt.sourceforge.net/Docs/PyQt4/resources.html), the `-py3` flag will make a file that is compatible with any Python 2.6 or greater, so unless you're using a really archaic version of Python, you should always use `-py3` for future-proofing – jpyams Nov 03 '17 at 19:26

There really isn't much to explain here, you have a resource file (e.g. icon.qrc), then you call pyrcc4 -o icon_rc.py icon.qrc which will create a module icon_rc.py which you then can import in your project.

It's all documented here.

i just cant convert this qrc file into a py module. when i use the code in cmd pyrcc4 -o icon_rc.py icon.qrc it says pyrcc4: File does not exist 'icon.qrc' – Thomas Apr 08 '13 at 12:38
And, does it exist in the directory wher you're running the command? – mata Apr 08 '13 at 13:41

File "", line 89, in File "F:\computing\Payrollv22\icon_rc.py", line 300, in qInitResources() File "F:\computing\Payrollv22\ritch_rc.py", line 295, in qInitResources QtCore.qRegisterResourceData(0x01, str(qt_resource_struct), str(qt_resource_name), str(qt_resource_data)) TypeError: qRegisterResourceData(int, str, str, str): argument 2 has unexpected type 'str' – Thomas Apr 08 '13 at 14:29

In Pyqt5 this command can be used Pyrcc5 input_file.qrc -o Out_file.py

We need to convert that qrc file into python file and then it can be imported to your code

its because when you also used pyuic5 to convert your UI to py, the resource file name from the UI sticks.

then use

Pyrcc5 input_file.qrc -o icons.py

remove from main_script.py

import icon_rc

and use

import icons

the when calling the actual icons from the icons module, you have to look at your qrc file prefix.

< RCC >
    < qresource
    prefix = "ico5" >
    < file > plugin.png < / file >
    < / qresource >
< / RCC >

if prefix is ico5 then you load icons with

 QtGui.QIcon(":/ico5/plugin.png")

and if prefix is , lets say,

<RCC>
    <qresource prefix="icons">

then its:

  QtGui.QIcon(":/icons/plugin.png")

you could try with pyside as well like:

--- pyside-rcc -o input.qrc output.py

pyside is different to pyqt4 – eyllanesc Dec 08 '17 at 04:36
Yes it is, but this is just for another option. – Nilesh K. Dec 08 '17 at 05:43
