Description Faisal 2023-09-16 18:23:54 UTC

Description:
The UI font for the presenter mode interface does not use the system UI font set by the desktop environment.

Steps to Reproduce:
1. Open presenter mode in any presentation.

Actual Results:
Presenter mode UI uses a font that looks like DejaVu Sans (I cannot be sure).

Expected Results:
UI uses the system font set by the desktop environment, just like other parts of the LO UI.


Reproducible: Always

UX team, please have a look at this enhancement. Thank you.

Why do you expect the system font? Sounds like a design wish rather an issue.

Comment 3 Faisal 2023-09-19 08:37:39 UTC

I have now marked this as an enhancement. But to me, using a non-system font breaks user expectation when the rest of the UI everywhere uses system font from menus to toolbars.

We discussed the topic in the design meeting.

Looking into the code it seems the presenter console has a lot of room for customization. It should be possible to set background image/color, font size, name, color etc. via registry - and consequently allowing to set a theme per extension.

The fallback is however to use Tahoma.

PresenterTheme::FontDescriptor::CreateFont() {
...
  if (msFamilyName.isEmpty())
     aFontRequest.FontDescription.FamilyName = "Tahoma";

And the majority of participants agree on the request to use the system font as long nothing is defined per theme.
