Silenio, this may be an either / or question...if the menu / header is stylable (i.e. supports font, color...attributes) on a given platform then we wouldn't need to go the 'owner draw' route. I was under the impression that it was only windows that didn't allow these attributes for menus for example.
There's also a bit of a difference between using owner draw *ourselves* to support styling vs exposing the API generally. IMO a Table with a stylable header would just expose the various attributes (setFont, setForegroundColor, ...) as if they'd been implemented that way from the start, making them match the other controls that support styling. The fact that 'under the covers' we may be using owner draw to implement those attributes would not necessarily be exposed to the users of the widget. Of course if a given control on a given platform supports neither the attributes nor owner draw we're pretty well beat.

SWT would have to expose API for this. I suppose the API would be similar to the custom draw API for TableItem/TreeItem (i.e. SWT.PaintItem/SWT.EraseItem/SWT.MesuareItem events). SWT would also have to expose the table header as a control with items: probably Header and HeaderItem. Here are links to the related documentation: http://msdn.microsoft.com/en-us/library/windows/desktop/bb775300(v=vs.85).aspx https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSTableHeaderView_Class/Reference/Reference.html http://developer.gnome.org/gtk/stable/GtkTreeViewColumn.html Menus can probably be 'owner drawn' on Windows and GTK (need to confirm). I am sure not about mac given it is an application menu.

Perhaps we should be producing platform-specific themes that use the menu (and header?) styling where it's supported in the true CSS 'best attempt' manner ? Question for SWT: Do either the table header or menu support 'owner draw' ? If so then using this would likely be far less effort that re-implementing them...

Obviously, this is a lot of work, but if that's what's standing in the way of the theming flexibility we want, then we should consider it. I'm not going to assume, a priori, any restrictions on what is possible. If you need the capability enter a bug requesting it. McQ.

Those are Aqua widgets and can't be changed, just like SWT Button(SWT.PUSH). The only solution is to change to a different platform, I think! Brian.
