TB 06 - Creating a Menu with an Icon as its Title (1-May-95)

Q How do I create a menu with an icon as its title, such as AppleScript(TM) and other products use?

A The menu data for the menu title must be 0x0501<handle> where <handle> is replaced by the the results of calling GetIconSuite(). An example snippet of code follows. This snippet assumes that the menu title is already 5 bytes long.

void ChangeToIconMenu()
{
                Handle              theIconSuite = nil;
                MenuHandle         menuHandle;
	
	GetIconSuite(&theIconSuite, cIcon, svAllSmallData);
	if (theIconSuite)
	{
		menuHandle = GetMenuHandle(mIcon);
		if (menuHandle)
		{
			// second byte must be a 1, followed by the icon suite handle
			(**menuHandle).menuData[1] = 0x01;
			*((long *)&((**menuHandle).menuData[2])) = (long)theIconSuite;
			// update display (typically you do this on startup)
			DeleteMenu(mIcon);
			InsertMenu(menuHandle, 0);
			InvalMenuBar();
		}
	}
}
