Hi Romain,
this is what I used. It might not be the "cleanest" solution, but at least it
works ;) I stole the idea from the qx.ui.table.cellrenderer.Icon and
qx.ui.treevirtual.SimpleTreeDataCellRenderer.
I am quite sure that this is not the best solution, because it has some
disadvantages, too:
1) The selected cell does not display the tooltip.
2) Browser dependent maximal text length.
3) No "fancy" tooltips, just text.
But I would love to see some better solutions. As I said, this worked for my
purposes.
The only really interesting part is of cause the _getContentHtml method that
creates a HTML DIV-element containing the tooltip as "title"-attribute.
Regards,
Kuddel
P.S.: Still hoping to see a nice "works with qx.ui.popup.ToolTip" solution ;)
