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

Qt Code: 
  1. MovieTabPane *m = new MovieTabPane();
  2. 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:

Qt Code: 
  1. ApplicationWindow()
  3. 	{		
  4. 		// Create MenuBar and Connection Menu
  5. 		mMenuBar = new QMenuBar( this );	
  6. 		mConnectionMenu = new QMenu( tr("&Connection"), mMenuBar );
  7. 		mMenuBar->addMenu( mConnectionMenu );
  8.  
  9. 		// Create Connect Action, and connect triggered() signal to message() <== temporary
  10. 		mConnectAction = new QAction( tr("Co&nnect"), mConnectionMenu );
  11. 		connect( mConnectAction, SIGNAL( triggered() ), this, SLOT( message() ) );
  12.  
  13. 		// Create Custom Widget
  14. 		mMovieTabPane = new MovieTabPane( this );
  15.  
  16. 		// Create Grid Layout and add mMovieTabPane
  17. 		mGridLayout = new QGridLayout( this );
  18. 		mGridLayout->addWidget( mMovieTabPane );		
  19.  
  20. 		// Tell AppWindow to use mGridLayout
  21. 		setLayout( mGridLayout );				
  22.  
  23. 		// Scale
  24. 		resize( 905, 495 );	
  25.  
  26. 		// Show
  27. 		show();
  28. 	}

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