Customizing the scroll bar and text input screen(s)

[illegalval]

Hi,
does someone know if it is possible to customize the appearance of the scrollbar in a theme? I wonder the same about text input screens, like when saving an eq preset, since on my Shanling Q1 these are very tedious to use, but maybe this is a general Rockbox limitation?

You can customize the width and location of the scroll bar in Theme Settings, Status/Scrollbar.

I use the Oscar theme but moved the scrollbar to the right and made it wider which works better for me.

'Text input you cannot change in settings.

The text input is somewhat tedious indeed. The Q1 is one of few touchscreen devices and the experience is less polished than devices with lots of buttons.

I'm aware of the scrollbar settings in the settings menu I was more wondering about if it's possible to change the look of the scrollbar (and keyboard) when making themes, since the scrollbar always looks the same, regardless of what theme I use.

Ok, I misread your question.

I thought there was a way to theme the scrollbar but I cannot find an example.

[illegalval]

No, i searched for it too! Would be nice to give it a theme-appropriate colour 

[illegalval]

I have a feeling that somewhere in the source code it is defined what colour the scrollbar (or items "untouched" by themes) have. Maybe it's possible to change this and recompile the release?

I thought the scrollbar colour is just set to the same colour as 'foreground colour"?

[illegalval]

It's never been like that for me! Hmmm, any developer who knows?

[chris_s]

The scrollbar color is the foreground color that the theme has set for the UI viewport (i.e. for the list). Themes can either pick a specific color (e.g. %Vf(000000)) or use the system-wide foreground color for that (%Vf(-)).

[illegalval]

So this actually needs to be defined in order for the scrollbar to adopt the colour? In the theme i'm using now it says "%Vf(ededed)". (None of the themes i've used has the scrollbar been in the foreground colour.)

[illegalval]

Further down it says (000000), let's see if changing this to (-) does anything

[chris_s]

You need to change it immediately after %Vi appears. Or, if the UI viewport is defined in the cfg file, it needs to be adjusted there. If no foreground color is explicitly defined for the UI viewport, it should use the global foreground color.

Unfortunately, as far as I'm aware, it is currently not possible to have the text color for the UI viewport be different from the scrollbar color.

[illegalval]

Hmm, i understand. Thanks for the great info and resources, gonna look into it.

Odd, that.  Whatever theme I pick the scrollbar takes the foreground colour that it sets.

It would, I presume, be possible to amend the underlying RB code to allow the possibility of setting a specific scrollbar colour, that would over-ride it taking the default foreground colour?  Would need some additional theme engine syntax, for either the cfg file or the wps/sbs file, I guess?  If anyone wanted that option badly enough.
