Currently, CoolBar lacks a couple features that could provide for more flexible layout, namely support for CoolItems that are "flexible spaces" (you can see this in a Mac OS X toolbar, where it will grow to fill available space, divided up among all flexible space items) as well as alignment -- if you want to just make a center-alignment coolbar, there's no intrinsic support.

Reproducible: Always

the attached patch is probably not all that useful on its own ... it probably deserves tooling support in jface so that you can specify contributions that are flexible spaces, but this is the underlying support in CoolBar.

this patch also sneaks in one other enhancements, which is that it hides the gripper if there is only one item and one row ... i hate when i see a coolbar that i can't drag around with but the gripper still appears (you can see that in the lower left of a default Eclipse install -- there are no fast views, but it looks like you can still drag around the item)

in win32 SWT uses the native control (rebar) to implement CoolBar.

Rebar doesn't have the type of support you are asking.

Sorry, without win32 support we can't add the feature.
