Re: Submenu woes

First, I make a new project : a Carbon C++ Application

Then I open main.cpp, and I paste the code I sent the list before, (or the latest version which is below) - at line 13,

and I add a line at MainWindow::Create (which is now line 80), calling the new function.

MenuTest();

One thing I can tell you is that if you do it this way, you need to set up your windows etc before you instantiate your MainWindow class.

MenuTest();

goes above

MainWindow* wind = new MainWindow();

If you don't, you will get no menus and no explanation!

I press command-y, the project compiles and begins debugging, the window appears, and the menuitems entered at root level work as expected, I click them and down drops a submenu. That works.

(screenshot removed in the name of netiquette)

Yet, for some strange reason, the "Special Menu" does not work as I have assumed in the code, based on a Carbon app I got from Apple, called Menu Views - ( http://developer.apple.com/samplecode/MenuViews/listing5.html )

(screenshot removed, but I have it if you need proof that i can run it without errors)

In the picture above, I have clicked the "Special" menu, and nothing dropped down, rather disappointingly :(

FYI,

Discussion
Using SetMenuItemHierarchicalMenu, it is possible to directly specify the submenu for a menu item without specifying its menu ID. It is not necessary to insert the submenu into the hierarchical portion of the menubar, and it is not necessary for the submenu to have a unique menu ID. Simply use 0 as the menu ID for the submenu, and identify selections from the menu by command ID.
(from the Menu Manager Reference, ADC Oct 06) - SetMenuItemHierarchicalMenu

//---------------------------------------------------------------------------------------------------------

// Creates some sample submenus.

static void CreateSubmenus( MenuRef topMenu, int count )

{

int i;

MenuRef menu = topMenu;

for ( i = 1; i <= count; i++ )

{

MenuRef submenu;

DuplicateMenu( topMenu, &submenu );

SetMenuItemHierarchicalMenu( menu, 4, submenu );

menu = submenu;

}

// clear the submenu link in the bottom-most menu (which otherwise will point to the first submenu)

SetMenuItemHierarchicalMenu( menu, 4, NULL );

}

Here is a slightly different, but not working, version of the generic menu maker... this is what I pasted into line 13 of main.cpp (I didn't do anything else to the boilerplate c++ application that xcode built for me)

#define DOES_NOT_WORK

void MenuTest();

bool isSpecialCommandsSubMenu(char * menustring);

bool isSpecialCommandsSubMenu(char * menustring){

return (menustring[0] == 'f');

}

void MenuTest() {

char * menustrings[5] = {"one", "two", "three", "four", "five"};

char * submenustrings[2] = {"subone", "subtwo"};

int basemenuindex = 201;

MenuRef specialmenuref;

CreateNewMenu(++basemenuindex, 0, &specialmenuref);

SetMenuTitleWithCFString(specialmenuref, CFSTR("Special"));

InsertMenu(specialmenuref, 0);

for (int mi = 0; mi < 5; ++mi) {

MenuRef m1ref;

CFStringRef m1string =

CFStringCreateWithCString(kCFAllocatorDefault, menustrings[mi],0);

CreateNewMenu(++basemenuindex, 0, &m1ref);

SetMenuTitleWithCFString(m1ref, m1string);

for (int smi = 0; smi < 2; ++smi) {

CFStringRef m2string =

CFStringCreateWithCString(kCFAllocatorDefault,submenustrings[smi],0);

InsertMenuItemTextWithCFString(m1ref,m2string,0,0,0);

}

if (isSpecialCommandsSubMenu(menustrings[mi])) {

#ifdef DOES_NOT_WORK

SetMenuID(m1ref, 0);

SetMenuItemHierarchicalMenu(specialmenuref, 0, m1ref);

InsertMenu(m1ref, kInsertHierarchicalMenu);

#else

InsertMenu(m1ref, 0);

#endif

} else {

InsertMenu(m1ref, 0);

}

DrawMenuBar();

}

I changed it a little bit

//here is the problem
SetMenuID(m1ref, 0);
SetMenuItemHierarchicalMenu(specialmenuref, 0, m1ref);

} else {
//this works fine
InsertMenu(m1ref, 0);
}
}
DrawMenuBar();
}

I can add menus directly to the root space quite easily, and I think I'm doing what the example code does, it must be something simple?
