BUG: SpinBar does not block mousewheel scroll when inside a scrollview

Type             : Bug
Priority         : Medium
Gambas version   : 3.9
Product          : GUI components


Description
-----------

The subject pretty tells you all.
When one tries to use the mousewheel on a spinbar inside a scrollview, the scrollview does scroll and the spinbar looses focus.
It happens with textboxes too, but not on spinboxes.

The following example trigs the bug:


Public Sub Form_Open()

  Dim aScrollView As Scrollview
  Dim aSpinbar As Spinbar
  Dim atextbox As Textbox
  Dim aspinbox As Spinbox
  Dim i As Integer
  
  Me.Arrangement = arrange.fill
  
  aScrollView = New ScrollView(Me)
  aScrollView.expand = True
  ascrollview.arrangement = Arrange.vertical
  
  For i = 1 To 20
    aSpinBar = New SpinBar(aScrollView)
    aSpinbar.h = 30
    atextbox = New TextBox(ascrollview)
    atextbox.h = 30
    aspinbox = New Spinbox(ascrollview)
    aspinbox.h = 30
  Next
  
End
