I have some problem about ui and i hope someone can help me.
The only way that X provide to disallow modification made by the user
on some widget (toggle, option menu,..) is "set_unsensitive".
Some time the value in toggle have no meaning in the context when it's
made unsensitive, some time have a meaning but the program want just
a read_only field.
Really a widget can assume three states:
enable (I/O field)
READ_ONLY (readable, with some feedback to avoid that the user thinks
that is a program bug that he is not able to modify)
really_disable (not allows change and also is greyed out to mean:
"user, do not care about any value you can find, have
no meaning in this context"
Motif allow read_only just for text but it do not have any user-feedback
between enable and read-only;
No one widgets set i know have read_only toggle.
I want to know if there is a "common used" way to provide this feedback
Thanks,
Giancarlo
