move parent window to the front.

I can't figure out how to use activateWindow() in QT 3 for this. This is not a member of the QDialog class which is what my windows are. In fact in QT 3 it appears that activateWindow() is part of the QWorkspace class. QWorkspace appears to be for doing MDI stuff. My app is not an MDI app and I have no objects that are of QWorkspace class. So I was not even able to figure out how to get this to build when I call activateWindow(). In QT 4 it appears that activateWindow() is part of the QDialog class.

I have figured out that this is a modality issue that had to do with the way I was instantiating the child dialog. What I was doing was creating the child dialog if a certain button was pushed on the main window and then destroying the dialog when returning control to the main window. What I have learned is that when a dialog is created this way there is no way to make it modeless (IE. it is always modal). What I ended up doing was to instantiate the child dialog during the application startup like this:

int main( int argc, char **argv )
{
    QApplication a( argc, argv );
 
   // create child dialog
    ProfileParms profParms;
    profParms.setModal(FALSE);
    profParms.show();
    //  hide dialog until needed
    profParms.hide();
 
    // create main window
    lprofMain w;
    w.show();
 
    // Setup signals and slots connections so that 
    // main window and child dialog can interact as needed
    QObject::connect(&profParms, SIGNAL(signalPickRGB()), &w, SLOT(slotPickRGBPatch()));
    QObject::connect(&profParms, SIGNAL(profileParmsOK()), &w, SLOT(slotUpdateProfileParmsText()));
    QObject::connect(&w, SIGNAL(showProfileParms()), &profParms, SLOT(slotShow()));
 
 
    a.connect( &a, SIGNAL( lastWindowClosed() ), &a, SLOT( quit() ) );
 
    // Start everything running
    return a.exec();
}

int main( int argc, char **argv )
{
    QApplication a( argc, argv );

   // create child dialog
    ProfileParms profParms;
    profParms.setModal(FALSE);
    profParms.show();
    //  hide dialog until needed
    profParms.hide();
    
    // create main window
    lprofMain w;
    w.show();

    // Setup signals and slots connections so that 
    // main window and child dialog can interact as needed
    QObject::connect(&profParms, SIGNAL(signalPickRGB()), &w, SLOT(slotPickRGBPatch()));
    QObject::connect(&profParms, SIGNAL(profileParmsOK()), &w, SLOT(slotUpdateProfileParmsText()));
    QObject::connect(&w, SIGNAL(showProfileParms()), &profParms, SLOT(slotShow()));


    a.connect( &a, SIGNAL( lastWindowClosed() ), &a, SLOT( quit() ) );

    // Start everything running
    return a.exec();
}

It took me a while to figure this out but it is working.

good u solved the problem

activateWindow is a function of QWidget in Qt 4.2.0 onwards. I am not sure about Qt 3
