## Declaration

Source position: comctrls.pp line 3766

`public property TCustomTreeView.ExpandSignWidth : Integer read FExpandSignWidth write SetExpandSignWidth default 2;`

## Description

ExpandSignWidth is relevant when ExpandSignType is set to tvestAngleBracket. It contains the line width used to draw the chevron symbol on the expand / collapse indicator for a tree node. It is not needed or used for other drawing styles in ExpandSignType.

The default value for the property is 2 (pixels). Changing the value for the property causes the control to be redrawn.

Use ExpandSignSize to set the overall width and height for an expand / collapse indicator drawn on the control.
