to broadcast or broadcast get a signal

• globalize the $application variable

global $application;

• send the module manager the signal (and get the return value) - note that broadcast_get will return the first result of a broadcast, and not continue broadcasting to all modules

$application->module_manager->broadcast(
$method,array("a","series","of","variables"));

$result = $application->module_manager->broadcast_get(
$method,array("a","series","of","variables"));

Common signals sent/recieved broadcast

Document Loading/Saving

pre_load_document(bookmarkid,URL)
load_document(bookmarkid,URL)
save_document(bookmarkid,URL)
post_save_document(bookmarkid,URL)
close_document(bookmarkid,URL)

all these deal with loading and saving the document,
load_document is also called repeatedly when flipping between active documents

load_from_data(bookmarkid,URL)
save_to_data(bookmarkid,URL)

when you have multiple editors, you should send these signals to other widgets when you loose focus, and you will recieve them when you get focus.

Getting Information

get_active_document()

If you are the active editor, then you should respond with an array of bookmarkid,URL to this call.

Menu/Toolbar button interaction

menu_emit(signal)

If the user presses on the menu, then the application will broadcast these signals to the modules - note you should ignore the save/load signals as they are handled directly by the loader.
you may simply redirect these signals straight to the widget which is being managed by the class
