Support for generating qrc file

[akshaybabloo]

Thank you for adding the generate function in #25

Could you add a way to generate qrc file too? - https://doc.qt.io/qt-6/resources.html

[akshaybabloo]

This is what I am doing so far to generate a qrc file:

import os
from pathlib import Path

from jinja2 import Environment, FileSystemLoader, select_autoescape
from qt_material import export_theme

root_path = os.path.abspath('../')

theme_path = os.path.join(root_path, "theme")
qss_path = os.path.join(root_path, "style.qss")
qrc_path = os.path.join(root_path, "style.qrc")

export_theme(theme='dark_teal.xml', qss=qss_path, output=theme_path, prefix=':theme/')

p = Path(theme_path)
files = ['/'.join(a.parts[-3:]) for a in p.glob("**/*.svg")]

env = Environment(loader=FileSystemLoader("."), autoescape=select_autoescape(['html', 'xml']))
template = env.get_template("styles.qrc")
render = template.render(files=files)

with open(qrc_path, 'w') as f:
    f.write(render)

styles.qrc

<!DOCTYPE RCC>
<RCC version="1.0">
<qresource>
    {%- for file in files %}
    <file>{{ file }}</file>{% endfor %}
</qresource>
<qresource>
    <file>style.qss</file>
</qresource>
</RCC>

Hi @akshaybabloo

There is no reason to use Qt resource system, since you can handle any resource with Python techniques, even the pyrcc tool will be deprecated in PyQt6.

Embed random files into a single Python file is not the proper way to handle resources, both Python and all operating systems has package manager that handle them without problems.

I honestly don't recommend using qrc for new developments.

I am not too sure if that can be done in C++ though?

[YeisonCardona]

Qt resource system is all fine and well for C++ programs where qresources get statically linked into the executable itself, reducing the number of files to be installed.

I could get back the qrc generation.

[akshaybabloo]

I am not too sure how the answer in #25 is being used. Because as far as I know qrc files are embedded into the static file.

Also, mac being mac, wants to know the path where it could find the icons from. I don't see any other way. Unless I am wrong.

Hi @akshaybabloo

I just add the rcc argument to the export_theme function.

export_theme(theme='dark_teal.xml', qss='dark_teal.qss', rcc='resources.rcc',
             output='theme', prefix='icon:/', invert_secondary=False, extra=extra)

The .qss will use the file:/ prefix by default .

Awesome! Thanks.
