OwnerDrawLabelProvider and PaintItem events for Grid/GridViewer? [message #57255] Wed, 06 August 2008 09:47 Go to next message

Hi

I'm trying to custom draw some things within the cells of the
Grid/Gridviewer using the OwnerDrawLabelProvider but it seems that paint
events doesn't get triggered for the label provider. The same applies to
SWT.paintItem on the Grid. Are these intended to be included or is there
another way of doing it?

With regards
Tommy

Now owner draw is a concept only part of native swt controls because
nebula grid is completely custom drawn you can simply replace the
cell-renderer if you need some custom drawing.

The concept of owner draw can't work in nebula grid.

why don't you use the same concept for the grid as well as for the native controls. I ran into the same problem. It should be possible to use the same labelprovider for the grid as well as for a SWT-backended JFace table.

Enrico

Hi,

Well Grid simply works different and you can't apply the concept without
investing time into it.

Naturally we could add callbacks into our draw CellRenders callback to
PaintItem, MeasureItem, ... but frankly at the moment this is not on our
list of things so the only possibility is to experiment with writing
your own renderer.

Please log a feature request so that we don't miss this feature.
