[Media] scrollbars always display

[yourpalal]

I can't reproduce this. What are you doing before selecting the mixer? Also, if the scrollbars are in the mixer view (I suspect so..) then this is probably a DefaultMediaTheme issue, as that view is provided by the media kit.

Select Audio settings and then Audio mixer. Visible on a slow hardware.

Although I'm still learning about the GUI API, can anyone give me a hint what files should I take a look to fix this?

Probably ​Audio mixer and ​DefaultMediaTheme sources.

As far I can see, this issue has something to do with the usage of BTabView in ​DefaultMediaTheme source file. Is it safe to use Layout-classes to solve this, or should I stick with fixed size/position items? I'm referencing the last warning presented by leavengood in ​Laying It All Out, Part 1

It is probably safe to use them, yes. The main issue to be wary of is backwards-compatibility with non-layout-aware apps. Hopefully this won't be an issue, the layout API attempts to be backwards-compatible in this way, but it could have problems. As you work, you should develop a small test application that uses the media kit views in a non-layouted context and test with it while you're working. The Media preflet already uses the layout kit, so it should be fine for sure.

There's also some documentation on the layout api in the haiku book, here: ​http://api.haiku-os.org/layout_intro.html

After a week diving in the code, I came into a strange situation: ​MediaWindow::_MakeParamView() calls ​BMediaTheme::ViewFor(fParamWeb, &hint), the later returns the TabView that is on the ticket's image (Gain controls and Setup). The problem is that any attempt to modify the code in ViewFor() is not reflected in the final executable. It is not being executed at all (put some printf there, and returned a new BStringView).

What can I do now? I compile using "jam -q Media", gcc2hybrid and a recent git checkout (no more than a week old)

The files in src/kits/media/ belong to libmedia.so, not the media preflet, so you'd need to be updating/replacing that instead.

thanks anevilyak, now everything makes sense

I give up, this turned to be too hard for me now =( maybe another time

The scrollbars don't flash, but they now always are displayed. This will require changes in BScrollView to fix.
