Default constructor.

Constructor which converts TEikScrollBarModel into TAknDoubleSpanScrollBarModel.

Values will be converted as:

TEikScrollBarModel TAknDoubleSpanScrollBarModel ------------------ ---------------------------- iScrollSpan -> ScrollSpan iThumbPosition -> FocusPosition iThumbSpan -> WindowSize 0 -> FieldPosition 0 -> FieldSize

Values will be internally stored with 15 bit accuracy, this means that the actual stored value may differ from the value given inside parameter.

Checks if given parameter is between internal min and max values.

Gets two highest bytes from TInt and constructs TInt16 from those.

Gets two lowest bytes from TInt and constructs TInt16 from those.

This method can be used to query if this model type is supported by the device. If model is not supported then this model and the behaviour of ALL methods defaults to TEikScrollBarModel behaviour with following rules:

TAknDoubleSpanScrollBarModel TEikScrollBarModel ---------------------------- ------------------ ScrollSpan methods -> iScrollSpan FocusPosition methods -> iThumbPosition WindowSize methods -> iThumbSize FieldPosition methods -> N/A FieldSize methods -> N/A

Constructs a scaled TInt16 value from given TInt value. Changes internal member variable values using ReScale()-method if needed.

Changes the used scale value and updates all stored attribute values if needed.

Gets the internal scale value.

Get methods for model attributes. These MUST be used instead of getting base class model values directly.

Get methods for model attributes values without scaling.

Sets two highest bytes of TInt.

Sets two lowest bytes of TInt.

Sets the internal scale value.

Sets the scrollbar type.

Set methods for model attributes. These MUST be used instead of setting base class model values directly.

model.SetScrollSpan(value1); value2 = model.ScrollSpan(); if (value1 != value2) { // we can end up here !!!! }

Set methods for model attributes values without scaling.
