Adding a tooltip for my center panel

Hi i have created a center panel calle cpanel. I want to add a tooltip to it so that when the user hovers over the cpanel it will say:

cPanel =new DrawingPanel();

cPanel.setToolTipText("Aaah, this is the center panel!.");

However, when i compile the above code i get the error message:

cannot find method setToolTipText(java.lang.String);

Does this mean i cannot add a tooltip to my cPanel? Please say it isn't so :(
