Hence the comment come seeking tech help about l2fprod property sheet. We want to fire property change event the moment user starts typing some value for a property. Have raised a thread in nabble : http://bit.ly/9xoqHi Please reply. Thanks. Hi,

In the case of a remove that'll leave dangling listeners in the filler. Looks like you don't really need them: the filler is useful only if AUTO_RESIZE_OFF which will always resize the table, so the notification reaches your filler via the componentEvent. Maybe you should listen to mode changes and un-/install the filler as appropriate - the filler can't cope with setting a new tableColumnModel - not the most probable event, but just for completeness :-) - the visual appearance isn't very appealing in LAFs where the viewport background is different from the table background. - the functionality is not quite the same as in explorer: f.i. a right click on the area below the filler should show the table's popup (as far as I remember Santhosh has an example of how to re-target a mouselistener) - the filler gets a bit confused with with LAF updates (again not the most frequent requirement, but ...): to reproduce in my example resize the last column with the mouse, toggle the LAF and move the mouse over the filler - the cursor now is always a resize cursor. The most probable reason (didn't dig, though) might be the mouselistener installed by the new LAF, which are not removed (as you do when creating the filler) Good work! Jeanette Hi Fred,
