I tried the recent 1.00 rc1 release and its not possible for me to capture a key-press event together with hardware_keycode. how can I detect if enter was pressed?
depending on what you are trying to do, there are several ways.if you want enter to activate a default response on a dialog, then you want to use the Gtk2::Dialog and set your desired response to be the default. http://developer.gnome.org/doc/API/2.0/gtk/GtkDialog.html#gtk-dialog- set-default-response
if you're not using a dialog, or not adding buttons to the dialog normally, you may need to make the buttons default-able -- use $widget->set_flags ('can-default') and then $widget->grab_default;
if you want pressing enter in an entry to activate the default button on a dialog, then use $entry->set_activates_default (1) . http://developer.gnome.org/doc/API/2.0/gtk/GtkEntry.html#gtk-entry-set- activates-default
if all of those are way off the mark and you're trying to do something else: the hardware_keycode member of the GdkEvent structure appears to be system-dependent, whereas the keyval member is not. thus, you want to use the keyval member with the mapping of keycodes provided by %Gtk2::Gdk::Keysyms, which you get by use'ing the Gtk2::Gdk::Keysyms module.
something like
if ($event->keyval == $Gtk2::Gdk::Keysyms{'Return'}) {
# user pressed return
}
should do what you want.
a cheesy little key-watcher is attached; it shows how to use the
keysyms.
