    Default QGraphicsView

    Qt Code:
    1. class ImenuPage:public QGraphicsView,public IBasePage
    2. {
    3. }
    To copy to clipboard, switch view to plain text mode 
    IBasePage is an abstract class and inherits from QWidget.

    Qt Code:
    1. ImenuPage::ImenuPage(EditorPage *_editor,QWidget *parent)
    2. :QGraphicsView(parent),IBasePage(_editor)
    3. {
    4. scene=new QGraphicsScene;
    5. scene->setSceneRect(230, 100, 560, 320);
    6. setScene(scene);
    7. }
    8.  
    9. class IBasePage:public QWidget
    10. {
    11. }
    To copy to clipboard, switch view to plain text mode 

    When I didnt use IBasePage I can create a scene and show images.But If I use above codes there is nothing.Why?

    Default Re: QGraphicsView

    I think this is because both your base classes have as base class QWidget.

    Therefore you will get compilations errors about ambiguous members/functions( I think ).
    If you really need two base classes, then I think you should use virtual inheritance.

    Regards
