Hi,
i am making an accounting report tool with wxTreeCtrl.
 
In the script you can save a project, reopen it, change it, save it again, etc.
I want to add an dialog when the user exits the script that gives him a warning if the tree has changed without saving.
 
The question is if i have a kind of event related to TreeCtrl that triggers when a change in item/tree attributes occurs and that can help me set a 'changes occured' flag.
 
Regards, Alejandro.
