Slider control window styles are set when a slider window is created. The following styles can be set when creating a slider control window. If no styles are specified, defaults, which are identified in the following descriptions, are used.

• Specify either of the following to determine the slider's orientation:

  SLS_HORIZONTAL

  The slider is positioned horizontally. The slider arm can move left and right on the slider shaft. A scale can be placed on top of the slider shaft, below the slider shaft, or in both places. This is the default orientation of the slider.
  SLS_VERTICAL
  The slider is positioned vertically. The slider arm can move up and down the slider shaft. A scale can be placed on the left side of the slider shaft, on the right side of the slider shaft, or in both places.
  
  Specify one of the following to position the slider within the slider window:

  SLS_CENTER

  The slider is centered in the slider window. This is the default positioning of the slider.
  SLS_BOTTOM
  The slider is positioned at the bottom of the slider window. This is valid for horizontal sliders only.
  SLS_TOP
  The slider is positioned at the top of the slider window. This is valid for horizontal sliders only.
  SLS_LEFT
  The slider is positioned at the left edge of the slider window. This is valid for vertical sliders only.
  SLS_RIGHT
  The slider is positioned at the right edge of the slider window. This is valid for vertical sliders only.
  
  Specify one of the following to determine the location of the scale on the slider shaft:

  SLS_PRIMARYSCALE1

  The slider uses the increment and spacing specified for scale 1 as the incremental value for positioning the slider arm. Scale 1 is displayed above the slider shaft of a horizontal slider and to the right of the slider shaft of a vertical slider. This is the default for a slider.
  SLS_PRIMARYSCALE2
  The slider uses the increment and spacing specified for scale 2 as the incremental value for positioning the slider arm. Scale 2 is displayed below the slider shaft of a horizontal slider and to the left of the slider shaft of a vertical slider.
  
  Specify one of the following to determine the slider arm's home position:

  SLS_HOMELEFT

  The slider uses the left edge of the slider as the base value for incrementing. This is the default for horizontal sliders and is valid for horizontal sliders only.
  SLS_HOMERIGHT
  The slider uses the right edge of the slider as the base value for incrementing. This is valid for horizontal sliders only.
  SLS_HOMEBOTTOM
  The slider uses the bottom of the slider as the base value for incrementing. This is the default for vertical sliders and is valid for vertical sliders only.
  SLS_HOMETOP
  The slider uses the top of the slider as the base value for incrementing. This is valid for vertical sliders only.
  
  Specify one of the following to determine the location of the slider buttons. If you do not specify one of these styles, or if conflicting styles are specified, slider buttons are not included in the slider control.

  SLS_BUTTONSLEFT

  The slider includes incremental slider buttons with the control and places them to the left of the slider shaft. These slider buttons move the slider arm by one position, either left or right, in the direction that is selected. This is valid for horizontal sliders only.
  SLS_BUTTONSRIGHT
  The slider includes incremental slider buttons with the control and places them to the right of the slider shaft. These slider buttons move the slider arm by one position, either left or right, in the direction that is selected. This is valid for horizontal sliders only.
  SLS_BUTTONSBOTTOM
  The slider includes incremental slider buttons with the control and places them at the bottom of the slider shaft. These slider buttons move the slider arm by one position, either up or down, in the direction that is selected. This is valid for vertical sliders only.
  SLS_BUTTONSTOP
  The slider includes incremental slider buttons with the control and places them at the top of the slider shaft. These slider buttons move the slider arm by one position, either up or down, in the direction that is selected. This is valid for vertical sliders only.
  
  Other styles that you can specify:

  SLS_SNAPTOINCREMENT

  The slider arm, when moved to a position between two specified values on the slider scale, such as between two tick marks, is positioned on the nearest value and is redrawn at that position. If this style is not specified, the slider arm remains at the position to which it is moved.
  SLS_READONLY
  The slider is created as a read-only slider. This means that the user cannot interact with the slider. It is used merely as a mechanism to present a quantity to the user, such as the percentage of completion of an ongoing task. Visual differences for a read-only slider include a narrow slider arm, no slider buttons and no detents.
  SLS_RIBBONSTRIP
  As the slider arm moves, the slider fills the slider shaft between the home position and the slider arm with a color value that is different from the slider shaft color, similar to the mercury in a thermometer.
  SLS_OWNERDRAW
  The application is notified whenever the slider shaft, the ribbon strip, the slider arm, and the slider background are to be drawn.
