I am trying to get somehow value of text = getTextToDisplay(cell, gc, rectangle.width, text); parameter from TextPainter#paintCell() into NatTableContentTooltip#getText(). I did not find the value in event or cell parameter of the getText() method. I need some condition, if displayed text is the same as a value in cell (not cutted for narrow cells). Thanks for a hint anybody!
The simple answer is, you can't. It is a painter that renders text according to table/cell states.
