Hi Greg,
thanks for your answer.
You are correct - Pivot's table rendering model is very similar to
Swing's and does not allow you to actually embed other components
within a TableView.
*sigh* and I thought I'd finally found a GUI toolkit that makes GUI
creation easy. Why is thinlet.com the only toolkit that allows that?!?
However, I had a similar requirement in a recent app - my solution
was to put a row of push buttons in a popup window that I show and
hide depending on the mouse position over the table view. I use
getRowAt() and getColumnAt() to determine what cell the mouse is
currently over.
I didn't thought of a popup. I'll try that. Thanks for the hint.
You could also have your renderer paint a "hover" state if you find
that the mouse moves over (or out of) one of your link button cells.
You could do something similar in mouseDown() or mouseClick() to
trigger the click action.
Meaning: repeat all of the behavior and paint logic that is already
there in LinkButton. Not a good option IMHO.
Regards,
Dirk.
Sorry there isn't an easier way. Hope this helps.

In my applications it is a _very frequent_ requirement to display
detail info when the user clicks a certain table cell. Somewhat
like master/detail, but the details shouldn't show up if the whole
table _row_ is selected but a particular _cell_. If the user clicks
another cell, other details should be shown. Also, the user should
get some visual feedback that some of the cells are "clickable",
while others are not.
So I would preferably use a LinkButton for those kind of cells, but
it seems there's no easy way to display a LinkButton as a cell in a
TableView. I can write a custom CellRenderer that extends
LinkButton and it displays correctly, but there is no behaviour:
the button doesn't "hover" on mouse-over, and actions attached to
it do not fire.
Apparently, Pivot is following the "rubber stamp" cell renderer
approach of Swing, which is good for performance, but makes it hard
to embed real components inside a TableView.
I already tried the common Swing trick to set the LinkButton as
cell editor and to enter edit mode automatically when the mouse
enters the table (and to cancel the edit when the mouse leaves the
LinkButton). But this doesn't work very well. Is there an easier way?
Thanks in advance.
