[vtkusers] qcombobox as a child of qvtkwidget doesn't show up on mac.

[Simon ESNEAULT]

Hello,

Sorry I got no time to give you a full example but this
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/TexturedButtonWidget
As well as this class vtkEventQtSlotConnect
should point you to the right direction, just connect the button widget
vtkCommand::StateChangedEvent to a slot and popup the menu inside the slot :

vtkButtonWidget* l_button_widget = vtkButtonWidget::New();
// Configure the button widget here, create a representation, map it to a
Viewport

vtkEventQtSlotConnect* l_connection = vtkEventQtSlotConnect::New();
l_connection->Connect( l_button_widget, vtkCommand::StateChangedEvent,
this, SLOT( update() ) );

Something like this
Good luck, sorry for the late reply

Simon
