Re: [RFC] The `Manage Identities' dialog

["M. Thielker" <balsa t-data com>]

Hi,

I had the need to detect a single click on a GtkCList in one of my other 
applications. I found that it is rather easy to do. I simply installed a 
handler for button press events and used the coordinates to find the row 
and column clicked. That way I was able to implement something that looked 
and acted like a real checkbox-in-a-list.
The same approach should work for almost every gtk widget and would do away 
with the counter-intuitive need to double-click.
AFAIK it doesn't adversely affect any functionality of the widget as long 
as displaying the update is not attempted from within the handler.
