Scroll bar visibility
Scroll bars appear at the right and bottom of the widget if visible. They
are used to reveal portions of the widget not currently visible. The
vertical scroll bar departs somewhat from traditional scroll bars by
actually moving the selection bar.
FLVS_NONE
No scroll bars will be/are visible. This will override AUTOMATIC and ALWAYS.
FLVS_HORIZONTAL
Only the Horizontal scroll bar will be/is visible. Use AUTOMATIC and
ALWAYS to determine when this scroll bar will be visible. The default
is AUTOMATIC. This is equivalent to (FLVS_HORIZONTAL | FLVS_AUTOMATIC).
FLVS_VERTICAL
Only the Vertical scroll bar will be/is visible. Use AUTOMATIC and
ALWAYS to determine when this scroll bar will be visible. The default
is AUTOMATIC. This is equivalent to (FLVS_VETICAL | FLVS_AUTOMATIC).
FLVS_BOTH
Both the Horizontal and Vertical scroll bars will be/are visible.
Use AUTOMATIC and ALWAYS to determine when these scroll bars will be
visible. The default is AUTOMATIC. This is equivalent to
(FLVS_BOTH | FLVS_AUTOMATIC) or (FLVS_HORIZONTAL | FLVS_VERTICAL |
FLVS_AUTOMATIC).
FLVS_AUTOMATIC
The scroll bars are visible only when needed. Scroll bars are
needed whenever a portion of the widget would be obscured.
This is the default and is optional. For this to work you must also
specify at least one of FLVS_HORIZONTAL, FLVS_VERTICAL, or FLVS_BOTH.
FLVS_ALWAYS
The scroll bars are always visible. For this to work you must also
specify which scroll bar(s) will always be visible by or'ing at least
one of: FLVS_HORIZONTAL, FLVS_VERTICAL, or FLVS_BOTH.
FLVS_HORIZONTAL_ALWAYS
The horizontal scroll bar will be/is always on. This is equivalent to
(FLVS_HORIZONTAL | FLVS_ALWAYS).
FLVS_VERTICAL_ALWAYS
The vertical scroll bar will be/is always on. This is equivalent to
(FLVS_VERTICAL | FLVS_ALWAYS).
FLVS_BOTH_ALWAYS
The horizontal and vertical scroll bars will be/are always on. This is
equivalent to (FLVS_BOTH | FLVS_ALWAYS).
