Toolbar border


Is it possible to remove the black border around the toolbar including the black oval at the start of the first toolbar.
(See the attached preview)

Changing the gap and/or background dit not help.


Welcome to the forum.

but this forum is bound to german users.
If you need help in english language you should go here:

I’d start by setting an empty border…


Not really. This part of the forum is international and belongs to the Docking Frames project.
I would guess the to is using this framework and so this is the right place for his question.

It is possible to customize these things, but the framework does only offer one default style for these lines. However you want to customize them - you are going to write some painting code of your own.

This example may give you a hint where to start:

Hi Beni,

This is exactly what I need. I don’t want titles at all (yet).
Since Swing does not give users the flexibility to customize the toolbars and multiple toolbars is not default available, I like DF most.

Thanks for this framework and keep up the good work!
