GUI Object

'A very simple to program GUI class
'Start by adding controls, then open the form.  Each control has an index.
'the form can be modal or non-modal.
'non-modal panel should have an event loop which runs while a zero or positive conrol index is 'returnd.  A negative index means ok or cancel was pressed by the user.
'A modal panel won't return until the user pressed ok or cancel, so an event loop isn't needed.

AddControl(ControlType As String, Caption As String, Value As Long, Min As Long, max As Long, Flags As Long) As Long

OpenPanel(Optional ByVal Modal As Boolean = False)

SetCaption(Caption As String)

SetSettings(Index As Long, Set_Value As Long, Set_String As String)

GetSettings(Index As Long, ByRef Returned_Value As Long, ByRef Returned_String As String)

WaitOnEvent(ByRef Returned_Value As Long, ByRef Returned_String As String) As Long


SetList(Index As Long, element As Long, Set_List As String)

SetSpacing(Set_Spacing As Long)
