[Gambas-user] How to exit loop and close the form

[Matti]

You have to specify a delay to Wait. From the docs:
"If Delay is not specified, the function processes all pending events and
returns immediately. In that specific case, input events (keyboard and mouse)
are ignored."

Try it like this:

Public Sub Form_Open()
  shouldStop = False
  Me.Show
  doIt
End

Public Sub btnStop_Click()
  shouldStop = True
End

Public Sub doIt()
  Dim i As Integer, j As Integer

  For i = 1 To 100
    If shouldStop = True Then Break
    ProgressBar1.Value = i / 100

    For j = 1 To 100
      If shouldStop = True Then Break
      ProgressBar2.Value = j / 100
      Print i, j	' My job here
      Wait 0.1
    Next

    Wait 0.1
  Next

  Me.Close()
End
