How the hell!?!?!

Posted on 1998-11-13

I have created a form at run time and want to place a main menu on it.  There could be quite a few copies of this same form (the app is an image viewer, and the form contains a large image depicting the image selected by the user).  

The problem is, when the user selects one of the menu items, its not returning the correct form as the owner, but always the main form (where the TMainMenu component was created).

Any ideas??

This sounds like an MDI app to me. Why do you want the menu on each form?

How do you create the copies of your form? Do you create the main menu in your form.Create function?
Perhaps you could give each form a number and write it to the main menus tag property?
If this doesn't help, please give us some code or at least some more informations about your creating logic.

Hi guys,

Its not an MDI application.  Its one main window, and when you double click on a thumb nail, it creates a window with the full image inside it.  

The reason I want a menu on each window is so the user can copy, delete, print or rename the image.

The way I create the form is like this:
procedure TMain.ViewImageInForm(Sender: TImage);
var ImgForm: TForm;
    Mnu: TMenuItem;

   ImgForm := TForm.Create(Application);
   With TImage.Create(Application) do begin
      Parent := ImgForm;
      AutoSize := True;
      ImgForm.Width := Width+8;
      ImgForm.Height := Height+60;
      OnClose := CloseViewWindow;
      Tag := WindowTag;
      Mnu := TMenuItem.Create(Application);
      With Mnu do begin
         Caption := ImgList[Sender.Tag];
         Tag := WindowTag;
         OnClick := SelectWindow;

I can post you the rest of the procedure if you like, but thats how I create it.  The only problem is when I try to add the main menu.

When the user selects an item from a menu disregard the owner as the indicator of which window the operation should relate to. Instead look at Screen.ActiveForm as this will be the form containing the actual menu that was accessed.

Thanks to rwilson.  I now have the active forms name!  Cool.

The way I ended up making the menus work is using this:

MMenu := TMainMenu.Create(ImgForm);

Thanks to all for you help.
