Summary0015013: QMainMenu behaves weirdly if QVTKWidget is the central widget of QMainWindow
DescriptionAs already posted to http://stackoverflow.com/questions/25797486/qmainmenu-behaves-weirdly-if-qvtkwidget-is-the-central-widget-of-qmainwindow [^] (without any outcome).
Qt Version: 5.3.1
vtk Version: 6.1.0

The main menu in my Qt/vtk application is behaving weirdly if the central widget is QVTKWidget. Errornous clicking behaviour on the menu is as follows:

First click: pop down
Second click: pop up
Third click: does nothing
Fourth click: pop down again

Now this wouldn't be that bad, but the problem is that the states are remembered. So if the user clicks the menu twice -- i.e., closes it manually -- the next click on the menu bar will not do anything, even if he used other GUI element in between. This leads to an annoying user experience.

I created a minimal failing example:


#include <QAction>
#include <QApplication>
#include <QLabel>
#include <QMainWindow>
#include <QMenu>
#include <QMenuBar>

#include <QVTKWidget.h>

int main(int argc, char** argv)
{
  QApplication app(argc, argv);

  QMainWindow mainWindow;
  QMenu *menu = mainWindow.menuBar()->addMenu("TestMenu");
  QAction *action = menu->addAction("TestAction");

  // Setting the central widget to QVTKWidget, produces a weirdly
  // behaving menu bar:
  // First click: pop down
  // Second click: pop up
  // Third click: does nothing
  // Fourth click: pop down again
  mainWindow.setCentralWidget(new QVTKWidget());

  // Setting the central widget to any other QWidget, like QLabel, produces a
  // normally behaving menu bar:
  // First click: pop down
  // Second click: pop up
  // Third click: pop down again
  // mainWindow.setCentralWidget(new QLabel("TestLabel"));

  mainWindow.show();

  return app.exec();
}
