I believe the table header has 'owner draw' support on the platforms we support (win32, cocoa and GTK). 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.
