[PySide] Help importing compiled Qt resource file from subfolder

Fri Oct 6 10:18:35 CEST 2023

Hi Henry/Alex,

Ideally you have to import the entire generated Python file to get access to the resources.  You can read about it here: https://doc.qt.io/qtforpython-6/tutorials/basictutorial/qrcfiles.html#generating-a-python-file
So, a simple "import images.compiledresource_rc" would suffice and you should be able to use your resources in code.

There are also many examples in the Qt for Python repository<https://code.qt.io/cgit/pyside/pyside-setup.git/tree/> that makes use of .qrc files. https://doc.qt.io/qtforpython-6/examples/example_quickcontrols_gallery.html would be one among them.

Sincerely,
Shyamnath

Subject: Re: [PySide] Help importing compiled Qt resource file from subfolder

Thank you Adrian.

A typical compiled resource file for me looks like this:
qt_resource_data = b"\
{snip}
"
qt_resource_name = b"\
{snip}
"
qt_resource_struct = b"\
{snip}
"
def qInitResources():
    QtCore.qRegisterResourceData(0x03, qt_resource_struct, qt_resource_name, qt_resource_data)

def qCleanupResources():
    QtCore.qUnregisterResourceData(0x03, qt_resource_struct, qt_resource_name, qt_resource_data)

qInitResources()

So is the solution
from images.compiledresource_rc import qInitResources

Will that register the resource data without any garbage collection or other problems?

BTW, as much as I love Python, the way it handles modules in folder seems very odd to me.

Henry

Hi Adrian

Is that line the same as:

    images.compiledresource_rc import anyFunction

That is, just importing any function will wire up resources like icons etc? I am asking on behalf of a team member, I can't try it myself atm.

Hello Henry,

for your current project structure it appears that this line in helpers.py would be enough for the import to work:

      from images.compiledresource_rc import someFunction

This should work regardless of the working directory, as long as helpers.py is imported from main.py, because the directory that main.py sits in is always added to PYTHONPATH.

Let us know if you have further questions or problems.

Betreff: [PySide] Help importing compiled Qt resource file from subfolder

Hello,

I have spend the last few hours trying to figure this out and now I have to ask for some help.

My project has grown to the point where is needs to be more organized, so I am moving modules from one huge folder into subfolders.  I use a resource file in QtDesigner and then compile it resulting in a "something_rc.py".  With the "one huge folder" approach I just imported this file into any module that uses dialogs - this is the only way that the images would show up in the widgets.  Now I am struggling to do this with the folder structure.

I made a simple example that shows the issue.  The tree is below and the attached zip file contains everything.

pkg
│   main.py
│   test_local.py
│
├───images
│       compiledresource_rc.py
│
└───utils
        helpers.py
        util.py
        __init__.py

Briefly, main can import test_local and util without any problems.  The issue is that if helpers needs to import the compiled resource file compiledresource_rc.  I swear that I have tried the exact syntax from different Internet resources and I cannot get it to work.

Can somebody please help me deal with this resource file?

Thank you for your help,
Henry
