Hello, :)

I have an application in which i connect a gtkeventbox to a function.
$handler_id = EventBox->connect('button-press-event', array($this, 'function'));
Then at later stage i need to disconnect it using disconnect($handler_id); but it's not working. Anyone knows a way to disconnect an event from gtkeventbox?

P.S.: I really like your site, It's been very helpful for me:)

Hi Manar,

The syntax

Code:

disconnect($handler_id);

is correct. Would you want to post some lines of code here so that we can see which part is not working right? Also, would suggest that you do something like:

Code:

$handler_id = EventBox->connect('button-press-event', array($this, 'function')); echo "bp1: $handler_id" . . . echo "bp2: $handler_id"; disconnect($handler_id)

Make sure the $handler_id in bp1 and bp2 are the same. If they are the same, things should work. If they are not the same (or its value is null or 0), then try to find out where did it get changed. Hope this helps. Regards, /kksou

Hi Manar,

Have just posted a sample code that shows the disconnecting of signals:
http://www.kksou.com/php-gtk2/articles/disconnect-a-signal.php

Compare this with your code. I think you should be able to find where it's not working.

Hello:) Thanks a lot for your reply!

The case that I have is not the same. I have an eventbox that should call 2 different functions depending on the condition. But this is not working because when the eventbox connects to function1, it works fine but when it calls the second function it is still connecting to the first function even if I am using the disconnect method.

In the example you gave me, my case is similar to pressing the eventbox the first time and calling function on_button_press, then the second time eventbox should stop connecting to function1 and connect to function2 instead. The piece of code that I am trying to use and is showing warnings is shown below:

function on_button_press($eventbox, $event) {
$eventbox->modify_bg(Gtk::STATE_NORMAL,
GdkColor::parse('#00ff00')); // note 3

global $signal_id;
$eventbox->disconnect($signal_id); // note 4
$signal_id2 = $eventbox->connect('button-press-event',
'on_button_press2');
}
function on_button_press2($eventbox, $event) {
$eventbox->modify_bg(Gtk::STATE_NORMAL,
GdkColor::parse('#0000ff'));
global $signal_id2;
$eventbox->disconnect($signal_id2); // note 4
$signal_id = $eventbox->connect('button-press-event',
'on_button_press');
}

Do you have any idea about how to use the same eventbox for calling two different functions?

Thanks for your help kksou,
Manar

Hi Manar,

Take a look at this example then:

Recipe 414: How to switch signal handlers on the fly - Part 1 - using connect disconnect?

Is this what you have in mind?

Great:)

It worked! the trick was to make the same signal id for all the events happening on the same eventbox. I was changing it every time.

Thanks for your support kksou:),
