OwnerDrawLabelProvider -> set other things than text [message #7900]

hi,

I want to create a custom Cell with a Spinner.

So on my ColumnViewer I set an OwnerdrawLabelProvider.
I looked :
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.jface.s nippets/Eclipse%20JFace%20Snippets/org/eclipse/jface/snippet s/viewers/Snippet010OwnerDraw.java?view=markup
and
http://keulkeul.blogspot.com/2007/08/tableviewer-et-ownerdra wlabelprovider.html

But this is only for custom text.

How can we put a new Control/Composite in the cell? Is there some examples
somewhere?

thanks for your help

Hi,

OwnerDraw and putting controls into the viewer are 2 completely
different things and in the end have nothing together.

I guess what you want is to fake the effect that the user thinks the
control is show all the time incontrast to how cell-editors work. The
problem is that then you are very likely run out of handles if you table
has many cells.

What we suggest to people to use instead is to fake the Control using a
picture (though for a spinner this could be a problem to because you
need to have an image for every spinner state possible).

We have a very complete example of this technique for Checkboxes if you
look at [1]. If the spinner is take to whole width of the cell ownerdraw
would not be needed though and normal label provider is enough.
