[Gambas-user] How to use MessageView when closing a form?

[bb]

(Internal #614)

We are trying to show a MessageView when the user clicks on a button
that closes the form or presses ESC. So in btnCancel_Click() we have

Public Sub btnCancel_Click()

  Action["Exit"].Enabled = False
  mvwOutput.Open("Search abandoned", Picture["icon:/32/emote-sad"])

  While mvwOutput.Visible
    Wait 0.1
  Wend 
  
  Me.Close

End

which works, but seems a terrible waste of electrons (top shows it
using 7% CPU).

Anyone got a better idea?
