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.

Answer 1

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.

Answer 2

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.

Answer 3

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

Answer 4

you could try with pyside as well like:

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

Answer 5

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")
