first, thanks for the patch and working on kdelibs stuff =)

some comments:

* you don't need Q_DECLARE_FLAGS since this isn't a flag (e.g. something you | 

* setCloseButton(int) should be setCloseButton(CloseButton); closeButton() 
should likewise return a CloseButton

* some better names might help clarify the API as well, e.g. 
setCloseButtonMode, closeButtonMode and ClostButtonMode or something similar 
that doesn't sound like the API actually sets a close button.

* does void setTabIcon(int index, const QIcon & icon); need to be public API 
or can that go into the private class? ditto for the protected methods.

* please follow the kdelibs coding style[1], e.g. this:

+   if(d->mCloseButtonSetting == KTabBar::NoCloseButton )
+      return;

should be:

+     if (d->mCloseButtonSetting == KTabBar::NoCloseButton) {
+        return;
+    }

* as for the findIconGeometry with the "there's gotta be a system behind 
it: --> insert here ;)" comment, you're right. there is a system: QStyle. the 
values you have there are for whatever specific widget style you are using 
(and whichever styles have the same sized tabs). you want to query the 
current style() for pixel metrics. take a look at the QStyle documentation, 
particularly for pixel metrics that start with PM_TabBar =) hth.
