13 \ingroup gpad
14 
15 A Control Bar is a fully user configurable tool which provides fast
16 access to frequently used operations. The user can choose between
17 buttons and drawn buttons (let's say icons) and assign to them their
18 own actions (let's say ROOT or C++ commands).
19 
20 The macro below shows an example of control bar.
21 To execute an item, click with the left mouse button.
22 To see the HELP of a button, click on the right mouse button.
23 
24 You have access to the last clicked button via the method
25 GetClicked(). For example, bar->GetClicked()->GetName()
26 will return the name of the last clicked button.
