BBjWindow::addHorizontalScrollBar
Description
Creates a horizontal scroll bar control in the BBjWindow.
Note: The BBjScrollBar is a standalone BBjControl that should not be confused with scroll bars that can be created with optional flags on windows, child windows, or edit-type controls.
To enable scrolling behavior in a window, horizontal or vertical scrollbars must be enabled and tracking must be turned off. Use the window creation flags $00000004$ (horizontal scrolling) or $00000008$ (vertical scrolling), and set tracking to 0 with window creation flag $80000000$
, BBjWindow::setTrack, or the TRACK Mnemonic - Toggle Tracking On/Off (SYSGUI).

If the ID parameter is not specified, a control ID is assigned dynamically using getAvailableControlID().
