GUI.Tooltip for converted GUIStyle element

The normal use of GUI.tooltip is explained in the GUI Scripting Guide,

and I know how to use it, but I`ve converted a Toggle Control Style to a button, and now I want to use a GUI.tooltip for the Toggle.

Here is some code I want to extend with a GUI.tooltip :

showWinCreate = GUI.Toggle (Rect(370,320,25,50),showWinCreate, "Create", "button"); 

What is the right synatax when adding a GUI.tooltip to a converted Control Style?

Try this:

    showWinCreate = GUI.Toggle (Rect(370,320,25,50),show WinCreate, new   GUIContent("Create","This is my tooltip!"),"button");
