SLIDER Statement

Syntax:

  SLIDER   id, x, y, width, height[, style]

The SLIDER statement creates a slider control within the dialog window. This control lets the user set, display, or modify a value by moving a slider arm along a slider shaft. The SLIDER statement defines the identifier, position, dimensions, and attributes of a slider control. The predefined class for this control is WC_SLIDER. If you do not specify a style, the default style is WS_TABSTOP and WS_VISIBLE.

id

Specifies the control identifier. The value is a signed integer -32768 through 32767, an unsigned integer in the range of 1 through 65535, or a simple expression that evaluates to a value in these ranges.
x
Specifies the x-coordinate of the lower-left corner of the control. The value is a signed integer -32768 through 32767 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The coordinate is assumed to be in dialog units and is relative to the origin of the dialog window.
y
Specifies the y-coordinate of the lower-left corner of the control. The value is a signed integer -32768 through 32767 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The coordinate is assumed to be in dialog units and is relative to the origin of the dialog window.
width
Specifies the width of the control. The value is any integer 0 through 65535 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The width is in n-character units.
height
Specifies the height of the control. The value is any integer 0 through 65535 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The height is in 1/8-character units.
style
Specifies the control styles. The value can be any combination of the styles specified for WC_SLIDER. You can use the bitwise OR ( | ) operator to combine styles.

Comments

The SLIDER statement is only used in a DIALOG or WINDOW statement.

Example

This example creates a slider control at position (40, 30) within the dialog window. The slider has a width of 120 character units and a height of 2 character units. Its resource identifier is 101. The style specification SLS_BUTTONSLEFT adds buttons to the left of the slider shaft. The default styles WS_TABSTOP and WS_VISIBLE are both in effect, though only the latter is specified.

#define    IDC_SLIDER       101#define    IDD_SLIDERDLG    502
DIALOG "Slider", IDD_SLIDERDLG, 11, 11, 200, 240, FS_NOBYTEALIGN |
        WS_VISIBLE, FCF_SYSMENU | FCF_TITLEBAR
  BEGIN
    SLIDER   IDC_SLIDER, 40, 30, 120, 16, SLS_BUTTONSLEFT | WS_VISIBLE
