Fonts are not rendered #106

Open furgo16 opened 9 months ago

furgo16 commented 9 months ago

While a list of available system fonts is displayed whenever there is a font selector in the GUI, selecting any given font does not seem to have any effect. The font remains always the same.

Fonts

Steps to reproduce

Create a new document and select the Draft workbench
Create a text annotation (T, E)
With the text selected, go to the View tab in the Combo View panel
Change the Font Name property: select any font from the combo box

Expected:

The text annotation is displayed in the selected font

Actual:

The text annotation is always displayed in the default font

@furgo16 Can you kindly share some logs by running the app from the terminal?

@soumyaDghosh thanks. Are you looking for something specific? There is not much of an output running from the terminal and following the steps to reproduce:

Can't find any snap specific logs! @chennes @ppd I think this is something with paths or similar. Please kindly look into this.

Information on how to add font support to snaps seems inexistent, or at least I'm unable to find it. The closest I found was this comment from a bug report:

Workaround for this issue: (in apps section) apps: some_app: command: some_app environment: XDG_DATA_HOME: $SNAP/usr/share FONTCONFIG_PATH: $SNAP/etc/fonts/conf.d FONTCONFIG_FILE: $SNAP/etc/fonts/fonts.conf

Of course this only works in devmode. After switching to strict mode program in snap ends with error that it can't reach /etc/fonts/fonts.conf file. I think should be resolved by adding interface.

These environment variables are not defined in FreeCAD's snapcraft.yaml file. On my system:

/snap/freecad/etc/fonts/conf.d is empty
/snap/freecad/etc/fonts/fonts.conf does not exist.
$HOME/snap/freecad/common/.cache/fontconfig/ has lots of files in it

Digging deeper, it seems that fonts should be handled by the kde-neon extension, as defined in snapcraft.yaml
