bug?: connect and php functions

Hello all, In my opinion, it should be able to do the following: > $btn2->connect_simple('clicked', 'print', $btn2->get_label()); which would cause the button's label to be printed out each time the button is clicked. However, although (or "because"?) that function is defined by php and accessible, I get: > PHP Warning: Unable to invoke signal callback 'print' specified in > somefile.phpw on line 20 in > somefile.phpw on line 27 If I write my own "echoit" method > function echoit($value) { echo $value;} and do a > $btn2->connect_simple('clicked', 'echoit', $btn2->get_label()); it works as expected. So is there a restriction in not being allowed to use functions defined by php and not the user? Bug? -- Regards/MfG, Christian Weiske
