Re: [gtkmm] pb when checking notebook pages ...

[cedric <cedric probesys com>]

Hi!

thanks for your response
so in fact, the purpose is to verify before opening ( = and creating/ appending) a page in the notebook that a same page is not already open. for instance, you have a list of bills, and when you double-click on one of them it appends a new notebook page. but actually, if we double clic 3 times on the same bill, it will open 3 new pages that are exactly the same ones! my wish is when we try to open a page that already exists, this existing page becomes the current one (with set_current_page). my problem is:
- is the bill the user double-cliked already open?
- if yes, set it as the current one, else create it

the second point is not my main problem, this is the first point that troubles me!

best regards,
cedric
