IconThemes

[triplus]

I prepared a PR to be included in FreeCAD 0.18.

https://github.com/FreeCAD/FreeCAD/pull/1967

I went over the workbenches and enabled missing icon themes support for commands on toolbars, not including Draft Snap toolbar for now, and for Constraints and Elements sections in Sketcher Tasks panel. This should make FreeCAD 0.18 rather (end user) usable, when it comes to the next version of IconThemes module for FreeCAD. Pursuing good icon themes support in other areas will happen in FreeCAD 0.19 development cycle.

Great! Yeah, ultimately all icons need to become themable. I think we still need a python version of that bitmapfactory function that checks for theme icons?

Not sure about that, using the standard approach should likely do:

I added support for Draft Snap and Tray toolbars in such way:

Basically with this PR icon theme can now be applied for all commands located on toolbars in FreeCAD 0.18.

Yeah, ultimately all icons need to become themable.

On my local branch indeed there are still some QIcons left, viewprovider icons, some Tasks panel related icons, macro dialog related ones ... Some of this areas will require small code adjustments. Therefore if FreeCAD 0.18 release is imminent, i guess best to target all that for FreeCAD 0.19.

P.S. And yeah, now some icons from Simple icon theme are missing.

Ingredients of a typical FreeCAD icon pack (all files located in a single folder):

• Icons preferably in the SVG format (view-top.svg)
• index.theme file
• .qrc file

The contents of an index.theme file:

Code: Select all

[Icon Theme]
Name=Demo
Comment=Demo icon theme pack
Inherits=FreeCAD-default
Directories=scalable

[scalable]
Size=64
Type=Scalable
MinSize=1
MaxSize=256

The contents of a .qrc file:

Code: Select all

<!DOCTYPE RCC><RCC version="1.0">
    <qresource prefix="/icons/Demo">
        <file>index.theme</file>
    </qresource>
    <qresource prefix="/icons/Demo/scalable">
        <file>view-top.svg</file>
    </qresource>
</RCC>

Resource compiler (rcc tool) is used to create an external binary resource data file, for use as a dynamic resource. On Linux:

Code: Select all

/usr/bin/rcc --binary demo.qrc -o demo.rcc

If newer version of rcc tool is used and to preserve support for Qt4 and older Qt5 versions (likely versions below Qt 5.9). Use the --format-version option:

Code: Select all

/usr/bin/rcc --binary demo.qrc -o demo.rcc --format-version 1

P.S. For testing purposes i temporarily modified IconThemes module in a way it will look for Gui/Icons/demo.rcc file inside user application data folder. On Linux that would be ./FreeCAD/Gui/Icons folder (other platforms). On FreeCAD start, whenever the file is detected, the data will get registered and an icon pack named Demo will get set. Useful for testing the Coil icon pack:

P.S. Feedback on how it works cross platforms is appreciated.

Demo.

For testing purposes i attached a demo icon theme pack containing one icon (view top). Rename the file from demo.zip to demo.rcc, attached file is not a ZIP file.

New release of icon themes module for FreeCAD is available. It supports icon packs provided from internal/external binary resource files. For now, until existing icon packs migrate, i left the previous icon themes functionality intact (Accessories -> Icon themes legacy).

Icon themes addon destroyed FreeCAD, I cannot run it (FreeCAD) - help.

First, please don't double post, and second i will need a bit more info. On what platform did the issue occur and i will assume it occurred, after you have enabled the Demo theme? If you start FreeCAD from the terminal or CMD. Any additional clues and errors provided? Does removing the demo.rcc file from the Gui/Icons folder resolve the issue?

P.S. Note that you can always manually install or remove the IconThemes module.
