Trying to implement QMainWindow...

I made a custom widget called MovieTabPane, which eventually will be inside a QTabWidget. But I've been testing it using this:

Code:

---

MovieTabPane *m = new MovieTabPane();
m->show();

---

Which has worked fine. But now, I'm adding the QMainWindow, and trying to put the MovieTabPane on as the central widget with a QMenuBar. The entire window comes out empty except the menu bar and widget, which are cramped into the top left corner.

Here's the code:

Code:

---

ApplicationWindow()
		: QMainWindow()
	{		
		// Create MenuBar and Connection Menu
		mMenuBar = new QMenuBar( this );	
		mConnectionMenu = new QMenu( tr("&Connection"), mMenuBar );
		mMenuBar->addMenu( mConnectionMenu );
 
		// Create Connect Action, and connect triggered() signal to message() <== temporary
		mConnectAction = new QAction( tr("Co&nnect"), mConnectionMenu );
		connect( mConnectAction, SIGNAL( triggered() ), this, SLOT( message() ) );
 
		// Create Custom Widget
		mMovieTabPane = new MovieTabPane( this );
 
		// Create Grid Layout and add mMovieTabPane
		mGridLayout = new QGridLayout( this );
		mGridLayout->addWidget( mMovieTabPane );		
 
		// Tell AppWindow to use mGridLayout
		setLayout( mGridLayout );				
 
		// Scale
		resize( 905, 495 );	
 
		// Show
		show();
	}

I'll be back in a few hours to check replies... gotta go write a Physics mid term ;)

try this code

Code:

---

ApplicationWindow::ApplicationWindow(QWidget *parent) 
        : QMainWindow(parent)
    {      
        // Create MenuBar and Connection Menu
        QMenu *connectMenu = menuBar()->addMenu(tr("&Connection"));
        // Create Connect Action, and connect triggered() signal to message() <== temporary
        mConnectAction = new QAction( tr("Co&nnect"), this );
        connectMenu->addAction(mConnectAction);
        connect( mConnectAction, SIGNAL( triggered() ), this, SLOT( message() ) );
 
        // Create Custom Widget
        mMovieTabPane = new MovieTabPane( this );
 
        // Scale
        resize( 905, 495 ); 
 
        setCentralWidget(mMovieTabPane);
    }

Thanks! That works perfectly. :D
