Title: Button handler for the root menu
Post by: fed on June 19, 2007, 01:42:51 AM
Do you know where the button handler is for the root menu.  I can't seem to find it in root_menu.c

first, please call the root menu the main menu, its named badly in the code...
now whats the problem?
the root_menu_ variable (its hidden in a MAKE_MENU() macro) is passed to do_menu() which does the actual button handling.

If you want techinal help the best place is on irc...

I would like to add a new function to the rec button.  I know how to change keymap.  I've even succesfully changed a couple of buttons in the rec screen, and added the function to recording.c.  Now, I'd like to add a button function to the main menu (the one that starts up when rockbox boots.  The one with 'Files, Database, Setting, Recording, ...).  But I cannot find the switch where I should be putting in the new function.

your being to vague too give proper help to...
menu.c in do_menu there is a switch for the action... add it there if (menu==&root_menu_)

In keymap, I assign an ACTION_SOMETHING to the rec button.  Then in recording.c I placed 'case ACTION_SOMETHING' in a switch that then ran my function when the button is pushed.  This worked.

I would like to do the same thing for the main menu, but I cannot find out where to place my function.

Does that help?

Also, what is 'grep'?

grep is the unix/linux program to search in files...

my previous post told you where to put your action case

I found no such location in menu.c in do_menu.

Sorry, but maybe I am missing something.  I cannot find all the STD eactions there either.
