Re: Focus weirdness

[David Munger]

Alright I've finally solved it. I had to pass the focus manually from the
GtkDrawingArea to the embedded xterm using XSetInputFocus(). Can somebody
suggest a cleaner or a more GTK-ish way of doing this?

I've tried with GtkSocket and gtk_socket_steal() but I still had to pass the
focus manually.

The minimal working example follows.

removing element from GHashTable returns FALSE

[Luka Napotnik]

Hello.

I'm using a GHashTable to store some structures. The keys are unsigned
integers. I create my hash table with:

g_hash_table_new(g_direct_hash, NULL);

Then I store same values with keys with:

g_hash_table_insert(my_hash_table, GUINT_TO_POINTER(3), mystruct);

But when I try to remove the value from the hash table I get FALSE from
g_hash_table_remove():

g_hash_table_remove(my_hash_table, GUINT_TO_POINTER(3));

The funny part is that I lookup for that same key just a few lines
before and it is found.

Any ideas what could be wrong?

Greets,
Luka

Glade signal connect data and full

[dhk]

All,

Could some explain how to use glade_xml_signal_connect_data() and
glade_xml_signal_connect_full()?  Some good examples would be helpful also.

I don't think I know the difference between the signal handler name and
the signal handler function that is used as parameters.

In my GTK program I want to pass different values for user_data for a
button click depending upon notebook tab that has focus.

Also is there a way to disconnect a signal made with
glade_xml_signal_connect_data() from an object?

Thanks,

dave
