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 vertical 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 $00100000$).

Example

rem 'Add a vertical Slider control to a window

rem 'Obtain the instance of the BBjAPI object
let myAPI! = BBjAPI()

rem 'Open the SysGui device
SYSGUI = UNT
OPEN (SYSGUI) "X0"

rem 'Obtain the instance of the BBjSysGui object
let mySysGui! = myAPI!.getSysGui()

rem 'Set addWindow param values
X = 10
Y = 10
WIDTH = 200
HEIGHT = 200
TITLE$="BBj Window"

rem 'Set the current context
