0: No border
 1: 3D border
 2: simple border
 

Not every border style (see Border) may support coloring. For instance, usually a border with 3D effect will ignore the BorderColor setting.

true means, that when the user moves the slider in the scroll bar, the content of the window is updated immediately. false means, that the window is only updated after the user has released the mouse button.

When the user presses a mouse in a control area where this triggers an action (such as scrolling the scrollbar), then usual control implementations allow to repeatedly trigger this action, without the need to release the mouse button and to press it again. The delay between two such triggers is specified with this property.

If this optional property is not present, clients of the component should assume a minimal scroll value of 0.
