Re: new window from button

["Jonathan Winterflood" <jonathan winterflood gmail com>]

You're welcome,

You should probably ask Matias rather than me, it's his example :D
I guess you just forgot to add the list when you replied (reply to all works
best..)

Other than that, the popup doesn't clear the GtkWidget *cbwindow pointer,
therefore a click after closing it will crash here : gtk_widget_show_all
(cbwindow);

You will need to connact a callback to the delete-event of the popup that
clears it.

The point of the example was just creating a window though ;)

Cheers,
Jonathan
PS: Ok, no comment I'm as bad as you when it comes to adding the list :D
