# TCustomListBox.ScrollWidth

The virtual width of the list box, in pixels.

## Declaration

Source position: stdctrls.pp line 676

`public property TCustomListBox.ScrollWidth : Integer read GetScrollWidth write SetScrollWidth default 0;`

## Description

ScrollWidth is an Integer property with the logical horizontal extent for the list box, or the scrollable area inside the control. When ScrollWidth is set to a value larger than ClientWidth, the horizontal scrollbar is displayed for the control.

The value for ScrollWidth is read from the widgetset class (at run-time) when a Handle has been allocated for the control. Changing the value for the property causes the value in the widgetset class to be updated.

The default value for the property is 0 (zero).

Use Columns to set the number of adjacent vertical columns used to display the items in the control.
