ToolTip for Graphical Items

[bwilde]

Hello,

I'm trying to make a tool tip pop up whenever the user does a
mouse-over on a filled rectangle that I've drawn on the screen. I have
no trouble creating the rectangle

Rectangle test = new Rectangle();

And it seems like there should be something like
test.setToolTipText("rectangle"), but as far as I can tell, there's
nothing like that. Is there some way to do this?

Thanks,
Ben

There's a part that says:

<quote>
Multi-part components such as JTabbedPane, JTable, and JTree override [the
String getToolTipText(MouseEvent)] method to return a string associated with
the mouse event location. For example, each tab in a tabbed pane can have
different tool-tip text.

A Rectangle is nothing more than a class built around the x and y
coordinate of its upper left corner, and its width and height. It's
just a mathematical representation. A tooltip is displayed in response
to something happening between a mouse and a Swing component, such as a
JPanel or those listed above or others. So in order for a Rectangle to
have a tooltip, a graphical representation of it needs to appear on some
component and a tooltip needs to be assigned to that component (or the
appropriate area of it).
