Hi guys.

I have an idea for a GSoC project. Before adding it to the wiki page at
http://dev.haiku-os.org/wiki/GoogleSummerOfCodeIdeas , I'd like to run 
it by you. Just to comment if it's in the scope of GSoC or desirable at 

A toolbar with symbols is a common GUI widget for applications. Since 
app development is increasing - and hopefully will continue to do so 
even before R1 is out - it would be a good idea not to force devs to 
roll their own. It's really essential IMO to keep Haiku's target of a 
consistent interface.

Here are a few features that I quickly came up with, the actual feature 
set is a topic for further discussion and also depends on the eventual 
project proposal:

 * horizontal/vertical positioning
 * tear-away toolbars
 * multi-tools that unfold (with a right-click?)
 * arbitrarily resizable symbols (vector)
 * show/hide labels
 * configuring via drag&drop
 * ...

Is the development and implementation of a "BToolbar" API in the scope 
of a GSoC project?
The result will of course be a private API until all the kinks have 
been worked out. Maybe it can soon have the status of the layout 
managing API.

Should the API be tackled for the GSoC, it would be great if a graphics 
designer (zuMi?) could be found, doing a consistent set of the most 
needed symbols. This could be financially supported as a Haiku Code 
Drive project or maybe a Haikuware bounty. An open design competition 
and voting like with the regular icons could be done, if you think it's 

IMO the symbols should of course be HVIF vector icons, maybe especially 
optimized for 16x16 as that may be the most used size. Also, I think 
this small size doesn't lend itself to the isometric perspective. 
Therefore I'd propose to be strictly 2D.
Which leaves decisions for selected/not-selected/not-selectable, color 
schemes etc.

 * color/grayscale
 * pressed button look
 * highlighted
 * inverted
 * outline
 * ...

As with the API, the actual design will require some discussion.
