[Gambas-user] How to be informed that a Form is closed?

[Hans-Martin Bundeshund]

Hello!

I have a MainForm in which the user can select different records from a db. A 
PictureBox in this form shows a status, if the seIected record has allready a 
note. If not, the user can open another Form where he can put some text into 
and store this as a new note into a DB. 

After he stores the note, the form gets automaticly closed. Now I must refresh 
my PictureBox in the MainForm, because there is now a note for this record. 

How can I be informed that the user has closed his action and so the form?

Best regards,
HM
