[API REVIEW REQUEST] RT-19659 - [TabPane] Support for draggable tabs

[Tom Schindl]

Hi,

The proposed API only allows to turn on/off dragging all together.

For your usecase I'd envision a future API which would allow one to
control the aspects you are asking for like.

The API i currently have in mind is but I have not yet explored:

// Would allow to cancel dragging of certain tabs
tabDndDragStartCallback: BiFunction<TabPane,Tab,Boolean>

// Would allow to cancel the dragging of the tab outside the container
// == only allows reordering
tabDndDragExitedCallback: BiFunction<TabPane,Tab,Boolean>

// Would allow the SOURCE to cancel the dragging to a specific target //
(could make tabDndDragExitedCallback obsolete)
tabDndDragOverTargetCallback: BiFunction<TabPane, Tab, Boolean>

// Would allow to cancel the drag over in the TARGET
tabDndDragOverCallback: BiFunction<TabPane,Tab,Boolean>

// Would allow to cancel the dropping of a tab in a container
tabDndDropCallback: BiFunction<TabPane,Tab,Boolean>
