hm. if we can do it from the style, even better. though it should also get rid 
of the toolbar separators (i can still see them in that screenshot)

as long as the cheating can be relied on ;)

looking at the QStyle stuff it looks like it should be possible to "peek" 
ahead at the next button and see if they belong to the same QActionGroup. it 
wouldn't be overly pretty, though. something like this in drawComplexControl 
for CC_ToolButton (coding out loud here):

bool drawGroupedLeft = false;
bool drawGroupedRight = false;
if (widget && !widget->actions().isEmpty()) {
    QActionGroup* group = widget->actions().first()->actionGroup();
    if (group) {
        QWidget* parent = widget->parentWidget();
        if (parent && parent->isA("QToolBar")) {
             int index = parent->actions().indexOf(widget);
             if (index != -1) {
	    if (index < parent->actions().count() - 1) {
                      drawGroupedRight = group == 
parent->actions().at(index+1)->actionGroup();
	    }
                  if (index > 0) {
                       drawGroupedLeft = group == 
parent->actions().at(index-1)->actionGroup();
                  }
             }
        }
    }
}

or something heinous like that. one might also be able to keep state to avoid 
some of the drawGroupedLeft'ing? (i'm not a qstyle expert by any means) then 
there'd be the fun of having to deal with separators, where one might put a 
separator in between two actions even though they belong to the same 
QActionGroup? hum.

would be nice if QStyleOptionToolButton included a QActionGroup*. would make 
things a *lot* easier =)

it would be Best if it grouped adjacent actions belonging to the same 
QActionGroup. separators often don't mean much, really, when it comes to 
action grouping.
