Using the Help module to show What's this is broken

[wwmayer]

Is there an existing issue for this?

Subproject(s) affected?

Core

Anything else?

By default the Help module should use the system browser to show the documentation.

on windows it opens the default browser

[wwmayer]

The behaviour depends on user settings:

FreeCAD/src/Mod/Help/Help.py

Line 112 in e4eb859

if FreeCAD.GuiUp:

By default the system browser isn't used.

[maxwxyz]

so the solution would be to remove the setting and use the OS browser?

[yorikvanhavre]

The webGui is still used as a fallback:

FreeCAD/src/Mod/Help/Help.py

Line 242 in e4eb859

WebGui.openBrowserHTML(html, baseurl, title, ICON)

I'll fix that to use the desktop browser instead.
