QApplication error in exec()
-
Hi all,
I have a weird problem when my applicarion tries to execute @app.exec() //QApplication object in main.cpp@
I'm trying to integrate an Ogre widget and a VTK widget on my application. All goes good if I use only one of them, but I get that error:
@Unhandled exception at 0x00a1fd88 in QtApp.exe: 0xC0000005: Access violation reading location 0x0672faf0@
I followed the error and it seems to crash on the Qt Core, when processing events in file "qapplicarion_win.cpp"
@
bool QGuiEventDispatcherWin32::processEvents(QEventLoop::ProcessEventsFlags flags)
{
if (!QEventDispatcherWin32::processEvents(flags)) //HERE CRASHES!!!!
return false;if (configRequests) // any pending configs? qWinProcessConfigRequests(); return true;
}
@I'm using Qt 4.7 under Windows 7.
Have somebody any clue?Thanks a lot!

Here it goes.
The 'main.cpp':
@//Main
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MainWindow *mainWin = new MainWindow();
mainWin->show();return app.exec();
//while (true){}
}
@'MainWindow.h':
@#ifndef MAINWINDOW_H
#define MAINWINDOW_H//Qt
#include <QMainWindow>#include "VTKWidget.h"
#include "OgreWidget.h"namespace Ui {
class MainWindow;
}class MainWindow : public QMainWindow
{
Q_OBJECTpublic:
explicit MainWindow(QWidget parent = 0);//, QtOgre::GameLogic gameLogic = 0);
~MainWindow();private:
//Class Members
Ui::MainWindow *ui;//Widgets
VTKWidget *mVTKWidget;
OgreWidget *mOgreWidget;
};#endif // MAINWINDOW_H@
And the constructor of 'MainWindow' in 'MainWindow.cpp':
@MainWindow::MainWindow(QWidget *parent):
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);//Create Ogre Widget
mOgreWidget = new OgreWidget( ui->widgetVis );
mOgreWidget->resize(800, 600);ui->verticalLayoutWidgetVis->addWidget(mOgreWidget);
ui->verticalLayoutWidgetVis->update();mOgreWidget->show();
//Create VTK Widget
//vtkRenderWindow* renWin = vtkRenderWindow::New();
mVTKWidget = new VTKWidget(this);
//mVTKWidget->SetRenderWindow(renWin);
//mVTKWidget->createScene();
//mVTKWidget->show();ui->verticalLayoutWidgetSmallVis->addWidget(mVTKWidget);
ui->verticalLayoutWidgetSmallVis->update();}@
I'm using the QVTKWidget from VTK source, and the Ogre widget like the defined "here":http://www.ogre3d.org/tikiwiki/QtOgre
Thanks
