It is possible to add some custom button on title bar of a DockableFrame?
It should be very useful to add custom functionality available on the DockableFrame in all status (float, or docked).
A little example is a DockableFrame that visualize a set of element and which can be visualized in different mode (list, thumbnail, details, etc.).
To change the visualization type the user could simply press on a ToggleButton on title bar instead that selecting it on a PopupMenu (that can contains specific functionality of the objects instead of the view) or in a menu in a menubar or in a toolbar.
Thanks.
