'dll' : 'so')); /* set up a function to collect the input from the entry and print it */ function get_input($entry) { $input=$entry->get_text(); echo "$input\n"; $entry->grab_focus(); $entry->set_text(""); } /* set up the window */ $window = &new GtkWindow(); $window->set_position(GTK_WIN_POS_MOUSE); $window->connect_object('destroy', array('gtk', 'main_quit')); /* add a box container to the window to allow more than one child widget */ $box = &new GtkVBox(); $window->add($box); /* add a GtkEntry to the box and connect it to the callback function */ $entry = &new GtkEntry(); $entry->connect('activate', 'get_input'); $box->add($entry); /* add a GtkButton to the box and use connect_object() so that it will pass the GtkEntry to the callback when it is clicked */ $button = &new GtkButton('Return or click me to echo input'); $button->connect_object('clicked', 'get_input', $entry); $box->add($button); /* display everything and set the main loop running */ $box->show_all(); $window->show_all(); gtk::main(); ?> |
