Re: Fwd: Reprogramming keyboard keys

[Glus Xof <gtglus gmail com>]

Hi Kjell,

Maybe I misexplained the problem... that it's not GdkEventKey.keyval related (and the #defined values in gdk/gdkkeysyms.h)...

In the last message, what I tried to ask for is the way to know the current keyboard (the physical one) configuration at the level of keys. More exactly, I need to know the value of each physical key will return.... and for that, I mentioned the gdk_keymap_* functions.

According the GDK reference: https://developer.gnome.org/gdk3/stable/gdk3-Keyboard-Handling.html

gdk_keymap_get_entries_for_keycode (...)  Returns the keyvals bound to hardaware_keycode...

In fact, my question is if exists another alternative, closer to Gtkmm/Gdkmm or must use 
(almost, for the moment) this Gdk one.

There is an alternative, but it's not closer to gdkmm.
The description of GdkEventKey.keyval at https://developer.gnome.org/gdk3/stable/gdk3-Event-Structures.html#GdkEventKey says: "See the gdk/gdkkeysyms.h header file for a complete list of GDK key codes." If you haven't downloaded the source of gtk+, you can look in the git repository:
https://git.gnome.org/browse/gtk+/tree/gdk/gdkkeysyms.h?h=gtk-3-22

Hi guys,

Thanks to all of you, again... so now, I'm understanding better... but in fact to solve all the entire problem, It just rests to obtain the *current* keyvals attached to each physical key. For that, I don't know if must to use the gdk_keymap_* functions (i.e. gdk_keymap_get_entries_for_keycode()...) or there is an alternative closer to Gdkmm.

There is an alternative:

entry.signal_key_press_event().connect(sigc::mem_fun (*this, &MainWindow::get_key_info), false);

i.e. after==false in the call to Glib::SignalProxy::connect().

Have you seen what's said about keyboard events in the gtkmm tutorial?

Hi Ian,

Thanks again but... I honestly don't see how to solve my problem...

What I really need is to catch the value when a key is pressed... not merely to know when the *entry* value has changed: What can I do from that ?...and How to know which value has changed ?. You see what I mean ?

Please, take this piece of code http://pastebin.com/LqTrph4i, and you'd verify that the handler "get_key_info" is not called when a key is pressed. And the question is... How to force it ?

Thanks,

Glus
