New
value.
New value to change the slider component to. The format of the information
depends on the component being changed and is indicated by the SMA_* message
attribute or attributes that are set.
- If the SMA_SHAFTDIMENSIONS attribute is set, the ulInfo
parameter is as follows:
usShaftBreadth (USHORT)
Width (for vertical sliders) or height (for horizontal
sliders) the slider shaft should be set to, in pixels. This is the breadth
the shaft should be.
If
the SMA_SHAFTPOSITION attribute is set, the ulInfo parameter is as
follows:
xShaftCoord (USHORT)
X-coordinate
to set the position of the shaft to within the slider window. This value
is expressed in window coordinates and represents the lower-left corner
of the shaft.
yShaftCoord (USHORT)
Y-coordinate to set the position of the shaft to
within the slider window. This value is expressed in window coordinates
and represents the lower-left corner of the shaft.
If
the SMA_SLIDERARMDIMENSIONS attribute is set, the ulInfo parameter
is as follows:
usArmLength (USHORT)
Length
of the slider arm, in pixels. This is the width of the arm for horizontal
sliders and the height of the arm for vertical sliders.
usArmBreadth
(USHORT)
Breadth
of the slider arm, in pixels. This is the height of the arm for horizontal
sliders and the width of the arm for vertical sliders.
If
the SMA_SLIDERARMPOSITION and SMA_RANGEVALUE attributes are set, the ulInfo
parameter is as follows:
usArmPos (USHORT)
Number
of pixels to be set from home to the slider arm.
