TControlBar Class Reference

A Control Bar is a fully user configurable tool which provides fast access to frequently used operations.

The user can choose between buttons and drawn buttons (let's say icons) and assign to them their own actions (let's say ROOT or C++ commands).

The macro below shows an example of control bar. To execute an item, click with the left mouse button. To see the HELP of a button, click on the right mouse button.

You have access to the last clicked button via the method GetClicked(). For example, bar->GetClicked()->GetName() will return the name of the last clicked button.

{
gROOT->Reset("a");

bar.AddButton("Help to run demos",".x demoshelp.C",
"Explains how to run the demos");
