requireToolTip() does not work for table cells with dynamic tool tip content

[Jay Guidos]

Hi All,

I am trying to test tool tips where the actual tooltip is calculated dynamically by the table instead of directly consulting the compoent's tooltip text.  In particular I am providing a table override:

new JTable() {
  String getToolTipText(MouseEvent ev)
  {
     return getCustomToolTipForCellAtLocation(ev)'
  }
}

It seems that getToolTipText(MouseEvent ev) is generally called from events generated by the ToolTipManager timer.  Looking at your requireToolTip() method, the tooltip is retrieved by pulling it from the component's static getToolTipText() method, and my table method override is never called.

It appears I have two problems:

   1- I have tried a couple of different ways to trigger a mouse event to my table's getToolTipText(MouseEvent ev) handler, but clicking on the table or a table cell does not seem to get it done.   Perhaps it would work if I could generate a mouse move over the table cell without a click, but how?
   2- even if I solve (1), your requireToolTip() method will not pay attention to my dynamically calculated tooltip anyway

Any recommendations on how to solve these problems?

Hi Jay,

I don't have an immediate answer for you. This is the first time I see this use case (it is valid, I just didn't encounter it before.) Let me do some testing and see how we can support it.

Regards,

Thanks Alex!  I am looking forward to seeing what you come up with.

Hello Alex, and Jay (and sorry for hijacking your topic, but I think
it's closely related),

Jay describes overriding getToolTipText(), but there's another way to
provide cell-specific tooltip too, which is to set the renderer's
tooltip. I deem it's a preferrable design when it is possible, as it
doesn't require subclassing JTable, but it sometimes leads to clumsy
code when the tooltip depends on information that are not in the cell
alone.
This section of the Swing tutorial describes both approaches:
http://download.oracle.com/javase/tutorial/uiswing/components/table.html#celltooltip

Anyway, I met the same problem - how to test those tooltips...

Indeed I was about to post the exact same question (how to test cell-
specific tooltips), when I discovered Jay's post.
I hope you can suggest a solution that covers both approaches.

Best regards,

J.

Hi there J,

Your observations are sound - indeed I was aware of being able to set the tooltip on the renderer.  And just as you commented, in this particular case my tool tips have dependencies that span the particular cell in question, and are more a consequence of the state of the entire model - so in this case I believe providing a table override is an appropriate approach.

Now all we need is Alex to come up with a brilliant way to integrate event-driven tool tips and we are good to go :)

Hey Jay,

I'll be looking into this tonight. My schedule has been pretty crazy
lately :(

Cheers!
