Constructing and running a dialogs is simple. For more information see, Symbian C++ API specifications:
void CDlgappAppUi::ConstructL()
{
BaseConstructL();
iAppView = new (ELeave) CDlgAppMainView;
iAppView->ExecuteLD(R_DLGAPP_MAIN_DIALOG); // modeless
AddToStackL(iAppView);
}
Because the dialog is modeless, CEikDialog::ExecuteLD() returns immediately after being called. The dialog can (and must)
be added to the control stack with the CCoeAppUi::AddToStackL() method, because modeless dialogs do not do this for themselves.
The application extends the dialog just as it would normally
extend a CCoeControl-derived view in order to achieve
the desired functionality. For more information, see Traditional Symbian
UI application architecture.
