I have a table with FocusCellOwnerDrawHighlighter (custom version of it, to be precise), but on selection all text in cells, which have SWT.Right align, shifts to the right border:

It seem that gc.setForeground(Color foreground) is causing this problem. Any hints or workarounds for this?

Hi,

I see what you're describing, but don't know why gc.setForeground() would
affect the position of drawn text, are you sure that removing this call
makes the problem not appear? Are you able to provide a snippet that shows
the problem happening, or at least, your custom
FocusCellOwnerDrawHighlighter implementation?

You can download snippet from here:
http://dl.dropbox.com/u/2610519/TestTable.zip

4 classes there, fully illustrates the problem.

Hi,

I've figured out what's happening and have released a fix to HEAD (
https://bugs.eclipse.org/bugs/show_bug.cgi?id=306877 ).

Believe it or not, a workaround you can use in the meantime is to set the
foreground for selected items to any Color != black.
