VSCROLLBAR

PLBCMP GUI Only

The VSCROLLBAR instruction defines an object variable for a vertical scroll bar. The scrollbar is a free-standing scrollbar. Many objects have properties that add scroll bars that are an integral part of the control. VSCROLLBAR allows the addition of a scrollbar to an object or group of objects that do not have integrated scroll bars. To define a VSCROLLBAR, use one of the following statement formats:

(1)	[label]	VSCROLLBAR	[%]
(2)	[label]	VSCROLLBAR	(arraysize)
(3)	[label]	VSCROLLBAR	^
(4)	[label]	VSCROLLBAR	^,{label}
(5)	[label]	VSCROLLBAR	^(arraysize)
(6)	[label]	VSCROLLBAR	^(arraysize),({target}),...,({target})

Where:

label

Optional. A Data Label.

Optional. Denotes the item as being GLOBAL.

arraysize

Required. An integer decimal constant, CONST variable, or EQUATEd value indicating the number of array items.

Optional. Denotes the item as being a POINTER.

target

Required. The name of a previously defined data item of the same type.

Flags Affected: NONE

Note the following:

The minimum, maximum, and increment values are defined when the scroll bar is initially created.
Multi-dimension arrays are supported up to a maximum of fourteen dimensions.
The ^ denotes Pointer Variable.
Although a VSCROLLBAR may be defined as Global, it is DESTROYed during a CHAIN instruction.
