I have a palette that contains PaletteGroups and and a PaletteDrawer. When
the palette is displayed the palette width is insufficient to display the
entire label for the PaletteDrawer. Everything looks good if I use all
PalletteDrawers.
Is there some property I can set that will cause the palette to display with
its width sized to contain the longest label?

I think I agree. If our layout managers respected figure visibility, then
drawerfigure wouldn't need to override getPreferredSize() at all. Open a
bugzilla. We can fix this for 3.0. If you need a fix for 2.1, the
workaround is to specify a widthHint to the GridData constraint object.

Aah. I misunderstood. I thought you meant that the drawer, in its
collapsed state, wasn't wide enough to completely fit the label of one of
its children (i.e., one of the palette entries inside the drawer). Right,
so the problem is still in getPreferredSize(int, int) in DrawerFigure. I
misspoke earlier when I said that,
when in collapsed state, the drawer's getMinimumSize() effectively returns
the preferred size of the header. A little more digging, and I realized
that it actually returns the minimum size of the header, which isn't wide
enough for the label.

GridData data = new GridData();
data.widthHint = 200;
widget.setData(data);
