Pop-up menu lists
Spencer Jones -- Spencer@azure.com

Environment: MSVC 4.0 Win NT 4.0
In my application I have a view menu with the options:
Toolbar
Status Bar
standard, as supplied by App Wizard. And my own commands:
RGB Values - for toggling a dialog bar added using Component Gallery
Magnify Image - selects a magnify tool, handled by me
Pointer Tool - selects a pointer tool, handled by me
Zoom Percent - pop-up with a list of zoom percents, handled by me.
What I have attempted to do is to add a pop-up menu that is available
when the right hand mouse button is clicked. I have created a new menu,
with the same options as those in the view option, and the same resource
ID.
My problem is:
1. the menu options added by App Wizard / Component Gallery do not work
in the pop-up menu. I.E. selecting Toolbar does not switch off the
toolbar.
2. The zoom percent allows the image to be resized, this works fine from
both menus. However I wish to check the selected percent. I have done
this in the OnUpdateHandler() for the function, and it works fine for
the main menu, but nothing is ever checked in the new pop-up menu. I
have placed a breakpoint in the handler and it is not called when the
pop-up menu is opened.
I get a handle to the menu using the CMenu function
VERIFY(menu.LoadMenu(IDR_MYPOPUPMENU));
and display it using:
pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON,
point.x, point.y, this);
where pPopup is a pointer to the pop-up menu, and 'this' is the View.
I have also tried making pPopup the pointer to the View menu, using the
main menu and the function GetSubMenu(1). But this gives the same
problem. Also the Toolbar, Status Bar and RGB Values, menu items never
become checked, and these should be controlled from the App Wizard /
Component Gallery derived code?
Any Help?

Try using the frame window instead of the view window :
pPopup->TrackPopupMenu( TPM_LEFTALIGN | TPM_RIGHTBUTTON,
point.x, point.y, AfxGetMainWnd());
This will direct the messages to the frame window, not the view.

Dispatch of the CommandUI messages is done by the frame window, not by the view.
Change "this" to AfxGetMainWnd(), and your popup menu should work as expected.

You mention that you pass a pointer to your view as the last parameter
to TrackPopupMenu(). This will invoke the CView::OnCmdMsg() handler when
a menu item is selected. If you look at the code in CView::OnCmdMsg()
you will see that when a view receives a command message it tries to
handle itself, then tries the document, then gives up. The handlers for
the commands you are having trouble with are in your main frame window.
Therefore, you need to pass AfxGetMainWnd() as the last parameter to
TrackPopupMenu().
The frame window will then route the message to your view, and when your
view gives up, it will handle the command itself or pass it to the
application.
