[Qt-interest] special trick needed to get toolbars to show up?

[kent williams]

I have this code in my main application window class (derived from QMainWindow):


  QToolBar *toolbar(this->addToolBar(tr("View")));

  // add icons for different views.
  static struct { const char *filename; const char *description;
    const char *action;
  } toolBarItems[] = {
    { ":/images/axialicon.jpg", "Axial View", SLOT(axialview()) },
    { ":/images/coronalicon.jpg", "Coronal View", SLOT(coronalview()) },
    { ":/images/sagittalicon.jpg", "Sagittal view", SLOT(sagittalview()) },
    { ":/images/3dicon.jpg", "3D View", SLOT(_3dview()) },
    { ":/images/4dicon.jpg", "4-way View", SLOT(_4dview()) },
    { 0, 0 },
  };
  for (unsigned i = 0; toolBarItems[i].filename != 0; i++)
    {
    this->m_ToolBarIcons[i] = new QIcon(toolBarItems[i].filename);
    QAction *curAction = toolbar->addAction(*(this->m_ToolBarIcons[i]),
                                             tr(toolBarItems[i].description));
    connect(curAction, SIGNAL(triggered()), this, toolBarItems[i].action);
    }

I do my initial development using OS X.  I'd never gotten my icons to
show up on the toolbar in OS X and figured I was doing something
wrong. I tabled this problem while I attacked higher-priority tasks.

Last week, I got around to building my application on Linux, and on
Linux, the buttons show up and work properly.

Does adding toolbars to a QMainWindow-derived class just not work on
OS X, or is there some sort of special dance step it takes to make it
work?
