Detailed Description

Convenience tab bar implementation.

This tab bar differs in several ways form the QTabBar:

• you can close a tab by double-clicking it or through its context menu.
• it works based on tab identifiers (a fixed id stored in tab data) rather than on tab indices, which might change when inserting or removing a tab.
• it accepts all drag-and-drop actions and emits signals to handle them.
