 Posted: Fri Aug 04, 2006 12:24 am Post subject: Connecting a signal to an object fails |
 |
|
Hello.
I have an object which generates and manages a GtkWindow. To prevent deletion and hide the window on delete_event, I tried to connect the delete_event signal to the function $this->guiWindowHide. This failed throwing the error message "Warning: Unable to invoke signal callback 'TeamOrga::guiWindowHide' specified in D:\...\main.php on line 153 in D:\...\main.php on line 50".
My code was $window->connect_simple('delete_event', array($this, 'guiWindowHide'));. So next I tried the same with gtk::true (array('gtk', 'true')) but it failed throwing the same error message.
When using an simple function like $window->connect_simple('delete_event', 'func_that_returns_true'); it works.
So, am I doing something wrong or is it simply a bug which is not yet fixed in PHP-GTK2? |

Assuming that this line of code and the method you're trying to hook up are both inside the object, it should work. You might double-check the spelling for your method name (obvious, I know, but possible). Failing that, you may have to post a little more actual code before we can see what's going on.

Not exactly that mistake, but nearly. I have declared the callback function as private, so it couldn't work. Now I declared it to be public and everything works fine. One of those baby-mistakes, hum..  Thanks, anyway. |

No, no, don't think like that, dude. We've all been there. "Growing pains" is much more palatable.
