Parameters

Parameter

Description

ID

Control ID number. It must be an integer between 1 and 32767 and be unique within a given top-level window.

x

Horizontal position of the upper-left corner of the control in current units.

y

Vertical position of the upper-left corner of the control in current units.

width

Width of the control in current units.

height

Height of the control in current units.

flags

Control flags, as follows:

Flag Description
$0001$ Sets the control to be initially disabled.
$0010$ Sets the control to be initially invisible.
$0800$ Draws a recessed client edge around the control.
$1000$ Draws a raised edge around the control.

 

Return Value

Returns the created horizontal BBjSlider object.

Remarks

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

If the x, y, width, and height parameters are not specified, they are all initialized to 0. This is typically for use with DWC windows that dynamically arrange their contents (window creation flag $00100000$).
