Hi!

I have a problem with a dialog window that doesn't close when I close the MainWindow. The dialog isn't modal, because I want a window at the side of my main window that I can display state of the progam.

I've read about parents and childs and thought that a child is closed when it's parent is. So either I've got this wrong or I've failed making the dialog a child to the main window.

Heres a shortened version of the code:


This is the dialog class:
Qt Code: 
  1. class OutlinerEditor : public QDialog
  2. {
  3.     Q_OBJECT
  4.  
  5.  
  6. public:
  7.  
  8.     OutlinerEditor ( std::vector<Renderable*> *v,
  9. 		          std::vector<Renderable*> *s,
  10. 		          QWidget *parent ):
  11. 	QDialog ( parent )
  12. 	{
  13. 	    setWindowTitle ( "Outliner" );
  14.  
  15. 	    treeModel = new TreeModel ( cmps );
  16.  
  17. 	    outliner = new Outliner ( sels, this );
  18. 	    outliner->setModel ( treeModel );
  19. 	    outliner->connectSelection ( );
  20.  
  21. 	    hLayout = new QHBoxLayout ( this );
  22. 	    hLayout->addWidget ( outliner );
  23.  
  24. 	    hLayout->setMargin ( 1 );
  25. 	    setContentsMargins ( 1, 1, 1, 1 );
  26.  
  27. 	    // and connections and so forth...
  28.  
  29. 	}// OutlinerEditor(v*,v*,W*)
  30.  
  31. };// class OutlinerEditor

This is the MainWindow class:
Qt Code: 
  1. class MainWindow : public QMainWindow
  2. {
  3.     Q_OBJECT
  4.  
  5. public:
  6.     MainWindow::MainWindow ( ):
  8. 	{
  9. 	    canvasFrame = new CanvasFrame;
  10.  
  11. 	    /* This is where I build the dialog and connects it, the last argument is the
  12.              * pointer to the parent.
  13.              */
  14. 	    OutlinerEditor *outlinerEditor = new OutlinerEditor ( NULL, NULL, this );
  15.  
  16. 	    /* This is how I show the dialog as not modal */
  17. 	    outlinerEditor->show   ( );
  18.  
  19. 	}// MainWindow()
  20.  
  21. };// class MainWindow
