Method CreateHandle

source/script_menu.cpp:923–969

ResultType UserMenu::CreateHandle()
// Menu bars require non-popup menus (CreateMenu vs. CreatePopupMenu).  Rather than maintain two
// different types of HMENUs on the rare chance that a script might try to use a menu both as
// a popup and a menu bar, it seems best to have only one type to keep the code simple and reduce
// resources used for the menu.  This is reflected in MenuCreate() and MenuBarCreate(), which
// create the UserMenu with the appropriate value for mMenuType.

		return OK;
	if (   !(mMenu = (mMenuType == MENU_TYPE_BAR) ? CreateMenu() : CreatePopupMenu())   )
		// Failure is rare, so no error msg here (caller can, if it wants).
		return FAIL;

	// It seems best not to have a mandatory EXIT item added to the bottom of the tray menu
	// because omitting it allows the tray icon to be shown even when the user wants it to
	// have no menu at all (i.e. avoids the need for #NoTrayIcon just to disable the showing
	// of the menu).  If it was done, it should not be done here because calling Menu.Handle
	// prior to adding items would have the effect of inserting EXIT at the top.

	UserMenuItem *mi;
	for (mi = mFirstMenuItem; mi; mi = mi->mNextMenuItem)
		InternalAppendMenu(mi);

	if (mDefault)
		// This also automatically ensures that only one is default at a time:
		SetMenuDefaultItem(mMenu, mDefault->mMenuID, FALSE);

	// Apply background color if this menu has a non-standard one.  If this menu has submenus,
	// they will be individually given their own background color when created via CreateHandle(),
	// which is why false is passed:
	ApplyColor(false);
