Hi,
switching the widget variant at runtime is possible. You can take a look
at the variant tab of the Control Demo.
Best,

Hi,
switching themes at runtime is currently not supported. If only the font
differs between the multiple themes, this would also involve a lot of
redundancy, I guess.
It's right, widget variants can be switched at runtime. But if you want
to go that way to change the font of every widget, you also have to
apply these variants to every widget. As a widget can only have a single
variant, this approach would prevent you from using variants for any
other purpose. To actually change fonts, you would have to change the
variant for all widgets, so you would save nothing compared to the
approach Stefan already outlined.
Don't forget to re-layout after switching fonts.
Best regards, Ralf
