In the StyledToolbar demo, you can see how to use this component, compared to the classic Delphi TToolBar.
In this picture, the Toolbar Demo compares the StyledToolbar and the classic Toolbar
The major differece is based on the control of the "size" of buttons when "ShowCaptions" is True: in standard Toolbar, the dimension is defined by the larger caption.
In the StyledToolbar the dimension is always defined by "ButtonWidth" property.
