To know if you up or down with your mouse wheel, use this function :
mouse.delta
Now, when you go up, you will have 1 value.
when you go down, you will have -1 value.

' gambas class File
PUBLIC SUB _new()
END
PUBLIC SUB form_OPEN()
me.center
END
PUBLIC SUB form_mousewheel()
label1.text = mouse.delta
select case label1.text
case 1
label2.text = "monter/up"
case -1
label2.text = "descENDre/down"
END select
END
PUBLIC SUB button1_click()
me.CLOSE
END

et par exemple on peu s'en servir pour faire un zoom sur un WebView (fenetre de navigateur) de la facon suivante :

On incremente la valeur zoom du WebView1 a chaque evenement MouseWheel sur Webview

Public Sub WebView1_MouseWheel()

WebView1.Zoom = WebView1.Zoom + mouse.delta / 10

End
