How do you HIGHLIGHT a menu item? How do you simply HIGHLIGHT whatever menu item you want from within your own BB application? The RIM Class MenuItem documentation Field summary shows static int flags like 'SELECT' and 'CANCEL_SELECT' but the Method summary for the class doesn't give you a clue what, if anything, you can do with these commands. The 'Menu' class ( Parent class for MenuItem? ) has the obvious setDefault() and setItemHighlight() methods but how do you just simply 'call' these parent Class 'Menu' methods from within your own application? Would it be some kind of 'super.setDefault()' call from within the constructor of your own 'MenuItem'? All I want to do is the same thing I see native RIM apps doing. If I have added screen jump menu items to my own application menu that lets the user go from screen to screen within the (same) application then whatever screen the person is currently on... when they press the MENU button again the last menu item chosen should stay HIGHLIGHTED until they pick another menu item and jump to another screen. This ought to be simple. What am I missing here? |
Answering my own question here... What I appear to missing are brain cells. When 'makeMenu' is called you then have a pointer to 'menu' and anywhere within the 'makeMenu' override while you are creating your MenuItems you can just call... menu.setDefault( (MenuItem) my_menu_item ); If you want to set/change the default menu item AFTER 'makeMenu' or at some other run-time point within your application then all you have to do is 'remember' what the last 'menu' handle was passed to the last 'makeMenu' method. Create yourself a 'global' that can seen from all 'screens' such as... static Menu _menu = null; ...and then every time 'makeMenu' is called anywhere in your application just update it with the 'Menu' pointer being passed to you by 'makeMenu'... _menu = menu; Then, from anywhere in your application, as long as you have also saved the 'MenuItem' handles for your own menu items saved to globals as well you can just call... _menu.setDefault( (MenuItem) my_menu_item ); |
