#25516 [Opn->Sus]: Gtk Widgets cannot be stored in Object Variables

ID: 25516 Updated by: alan_k@php.net Reported By: auroraeosrose at hotmail dot com -Status: Open +Status: Suspended Bug Type: PHP-GTK related Operating System: Win XP Pro SP1 PHP Version: 5CVS-2003-09-12 (dev) New Comment: I think without a final 'release' version or some ability to debug on XP it will be imposible to diagnose or fix this. Suspending until PHP5 & PHP-GTK are actually released. You may just try removing all the PHP & PHP-GTK binaries and update from the latest snapshots.

There is a BC flag in php.ini that is supposed to turn off/on object cloning.. - is that set? ------------------------------------------------------------------------ [2003-09-12 10:14:37] auroraeosrose at hotmail dot com Description: ------------ I went to the mailing list first to make sure I wasn't losing my mind and they assured me I'm supposed to be able to store a widget in an object variable. I'm using builds from http://kromann.info for php5 and php-gtk for php5 The code I'm using is very simple - it's just supposed to show a window. The class is below - very basic. Here's the deal - when use $this->window inside the newWindow method nothing happens. The script runs, I guess, and that's the end of it. It seems to be impossible to assign a php-gtk widget to an object variable, which is really, really annoying Reproduce code: --------------- <?php dl('php_gtk.dll'); $class = new Window(); $window = $class->newWindow('main', 'Product :: Title Here'); $window->connect('destroy', 'destroy'); $window->connect('delete-event', 'delete'); $window->show_all(); Gtk::main(); function delete() { return FALSE; } function destroy() { GTK::main_quit(); } class Window { var $window; function newWindow($name, $title, $type = GTK_WINDOW_TOPLEVEL, $width = NULL, $height = NULL, $position = GTK_WIN_POS_CENTER) { //find height and width if(is_null($width)) { $width = gdk::screen_width()-50; } if(is_null($height)) { $height = gdk::screen_height()-100; } //create the window $this->window = new GtkWindow($type); $this->window->set_name($name); $this->window->set_title($title); $this->window->set_default_size($width, $height); $this->window->set_position($position); return $this->window; } } ?> Expected result: ---------------- A window should appear Actual result: -------------- Nothing happens, no errors, the script just kind of acts like it was run and closed. Here's some more weirdness - php seems to be dying completely (and silently) on $this->window = new GtkWindow($type); because I can't echo or print_r or var_dump anything after that call, while before I can just fine, and I'm not getting any errors. And if I change every occurence of $this->window to just $window and try to do a var_dump, nothing is printed but the window appears. If I do a print_r on $window I get GtkWindow Object - and the window appears properly - so the problem is with the object variable. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25516&edit=1
