Is there a hover Event for a table row in a TableViewer

Question

i have a JFace table-viewer, which consists of large number of rows, i thought that it would be better if there is a short description for each row,as a workaround i was trying to implement doubleclick listner but that's not apt to my need,i don't know if there is an event like hover for this,which shows a tooltip containing a brief info about the particular row.

Answer 1

The answer to this question depends somewhat on the exact implementation of your table viewer. Having said that, the primary options are:

• Add a MouseTrackListener to the underlying table
• Add a SWT Listener for SWT.MouseHover to the underlying table
• If you use a CellLabelProvider, have a look at the various getToolTip...(Object) methods

For the first two, you have to figure out the row element yourself - look at event.item.getData(), whereas that is provide to you in the last option...
