Extend and override NatTableContentTooltip#getText() that only returns a value if the text rendered by the underlying painter ends with ... - otherwise return null

Hi Dirk, thank you for your reply, i don't describe this question very well, in fact, i try to extend the DefaultToolTip, and added nattable object for this tooltip. and override the getText() function. here i can get the cell really value by "this.natTable.getDataValueByPosition(col, row)". but i don't know how check " the text rendered by the underlying painter ends with ... "

i also checked NattableContentTooltip.java, we can get the " ILayerCell cell " and "ICellPainter painter", i don't found how get "Text rendered which end with...", can you describe some detail things, thank you very much.

Honestly I don't have a solution out of the box and would need to think about this and test for a while. But currently I don't have time for this.

Dependent on your configuration a simple solution could be to calculate the length of the text via GC and if it is bigger than the cell width, provide a tooltip. But that would not work in case you have line breaks for example.
You could also try to extend the TextCellPainter and connect that to your tooltip implementation and set values only in case the text is cut.
