    Default QT ActiveX server doesn't work with Delphi 7.0

    Issue: I need to make an ActiveX control (in-proc-server) to use it with Borland Delphi 7.0 project.
    Solution: My class Svr_3 inherits from QWidget and QAxBindable:
    class Svr_3 : public QWidget, public QAxBindable
    {
    Q_OBJECT
    public:
    Svr_3(QWidget *parent = 0);
    private:
    Ui::Svr_3Class ui;
    public slots:
    int SomeMeth (const QString& aVal);
    };

    It works as in-place ActiveX control in IE8, MS Word. It repaints itself and executes SomeMeth () correct.
    It DOESN’T work with Delphi. It draws in design-time incorrect, it isn’t visible in run-time. But it executes SomeMeth () correct.

    How can I solve this problem?

    Opensource QT 4.6.0, VS2005

    And why did you think it was important to bring a nearly 7 year old post back from the dead to report this? At this point, who cares?
