NAME
Curses::UI::AnyEvent - Sub-class of Curses::UI for AnyEvent
SYNOPSIS
use strict;
use Curses::UI::AnyEvent;
my $cui = Curses::UI::AnyEvent->new(-color_support => 1);
$cui->set_binding(sub { exit }, "\cC");
$cui->set_binding(sub { $cui->mainloopExit() }, "q");
my $win = $cui->add('win', 'Window',
-border => 1,
-bfg => 'red',
);
my $textviewer = $win->add('mytextviewer', 'TextViewer',
-text => '',
);
my $watcher = AE::timer 1, 1, sub {
$textviewer->{-text} = localtime() . "\n" . $textviewer->{-text};
$textviewer->draw;
};
$textviewer->focus();
$cui->mainloop();
DESCRIPTION
Very simple integration with Curses::UI and AnyEvent. Just create a
"Curses::UI::AnyEvent" object instead of a "Curses::UI" one and use it
as normal.
You'll probably want to install some AnyEvent watchers before you call
"mainloop()". Alternatively, if you want to setup the async handlers
without blocking, you can use the "startAsync" method:
$cui->startAsync();
## add some other handlers...
AE::cv->recv; ## block here instead
Most things work, including mouse support.
DIALOGS
Curses::UI unfortunately implements a separate event loop in order to
handle modal dialogs. This conflicts with our AnyEvent loop so it needed
to be stubbed out by replacing the internal "tempdialog" method.
Informational dialogs work normally, except they return immediately
instead of waiting for the dialog to be dismissed:
$cui->dialog("Some information: blah blah blah");
## ^^ Returns immediately, not when dialog dismissed!
If you wish to perform some action after the dialog is dismissed, or in
the case of query dialogs you wish to access the value, there is a new
"-cb" parameter that accepts a callback:
$cui->question(-question => "What is your name?",
-cb => sub {
my $name = shift;
## ...
});
Note that while a dialog is active, all keypresses are routed to that
dialog instead of the main screen. However, since the main event loop is
still active, it can still be processing externally triggered or timed
events.
BUGS
There are still a few places that call `do_one_event()` in a loop
instead of using the AnyEvent loop so they will busy-loop until
dismissed by the user and no background events will be processed. The
cases I know about are search windows and fatal error screens. I may
stub these out similarly to dialogs if I need them (patches welcome).
