Draft preferences: problems with font settings

[yorik]

IIRC for the Draft ShapeString, the font handling is done by freefont. I don't know why the fonts are locked that way on windows, nor why freefont wouln't be able to access them read-only somehow... This needs further investigation

I'd really like to be able to get rid of that need to specify Draft ShapeString fonts by file path, and use the same Qt system as the rest of FreeCAD... Unfortunately I didn't find yet a reliable, multi-platform way of relating a Qt font with a file path...

[wandererfan]

If there's a Windows user out there that hasn't messed too much with attributes, permissions, etc, on the Fonts directory, could they try the following please?

In Tools>Edit parameters, add a parameter to the Dialog section as shown in this screen grab:

WindowsPrefDialogParm.png (62.2 KiB) Viewed 247 times

On my Windows box, setting this parameter to true allows access to the Windows/Fonts directory. I'm not sure my machine is a valid test environment anymore since I've set and reset the Fonts properties so often.

Thanks,
wf

Yes, it works! I'll have to get used to the dialog, but I can live with that. Thank you!

I've made a crude hack to only have the non-native dialog for the ShapeString Task Panel by changing src\Mod\Draft\DraftGui.py around line 2460 from:

Nice. I've been fixated on the Preferences aspect, haven't really thought about the dialog.

I don't see your PR in the Q?
