ListBox Deselect? 1

[shussai2]

Hi guys,

I have a listbox setup. I have few entries in it. Now what I want to do is to deselect it. Meaning a user cannot go into the listbox and choose an entry (select the entry by pressing a button). Basically a user can just view the listbox with entries in it. Your help would be really appreciated.

Regards,

Sajjad

Simply set the listbox's -state to [tt]disabled[/tt], instead of its default of [tt]normal[/tt]. This prevents the user from interacting with the listbox. However, if you have the listbox connected to a scrollbar, it does not disable scrolling, which is almost always the desired behavior.

Note that setting a listbox to [tt]disabled[/tt] also prevents most programmatic changes as well. For example, the insert and delete operations have no effect on a disabled listbox. Therefore, if you want to make changes to the listbox, you'll have to set the -state to [tt]normal[/tt] first, then set it back to [tt]disabled[/tt] once you're finished.

The -state option only exists in version 8.4, how can this be done in say 8.3?

I have read that you can do something like
bindtags $listbox "$listbox . all"

but how can you enable it again after that?

Thanks!
