Hi,
I'm using the latest GTK snapshot (gtk+970606), and cannot find a way
to make the "entry" widget signal when user "accepts" the value,
eg. presses the enter key.
I looked into gtkentry.c and found that entry_signals defines only
three signals ("insert_text", "delete_text" and "changed"), also
control_keys[] doesn't define any action for ctrl-m or ctrl-j.
Also any signals are raised only after processing gtk_entry_key_press
meaning that the signal handlers won't get their hands on the keypress
before the ^M/^J is already lost..
I would need to verify the entry value after user has "finished" with
it (presses enter), now it seems impossible because the available
signals are called after every character with no way to tell when
enter has been pressed.
I could of course try something like fiddling with class
key_press_event field but dunno.. Also, I would need capability to
change the entry field into a password field, eg. with no character
echo (or replacement with "*"?), I think this needs fiddling with
gtk_entry_draw_text and a boolean value (maybe a flag value, with
options to display text normally, as empty regardless of contest or
replace characters with an asterisk).
Having said that, I figured out there's no help like own help and
patched gtkentry.[ch] to have an additional signal "accept" which is
invoked when the user hits GDK_Return key. Works For Me(tm) patch,
that is.
