Pen: IGxPen;
The Pen property determines the pen that renders arrow border.
Executing the example requires a form with the Button1 button and the SpeedometerBox component named SpeedometerBox1.
Sub Button1OnClick(Sender:Object; Args: IMouseEventArgs);
Var
s: ISpeedometer;
v: ISpeedometerView;
ScaleView: ISpeedometerScaleView;
ArrowView: ISpeedometerArrowView;
Pen: IGxPen;
Begin
s := SpeedometerBox1.Speedometer;
v := s.View;
s.BeginUpdate;
ScaleView := v.ScaleViews.Item(0);
ArrowView := ScaleView.ArrowViews.Item(0);
Pen := New GxPen.CreateSolid(GxColor.FromName("Red"));
ArrowView.Pen := Pen;
ArrowView.Shape := SpeedometerArrowShapes.Triangle;
ArrowView.Width := 0.1;
s.EndUpdate;
End Sub Button1OnClick;
After executing the example, on clicking the button, the formatting of scale arrow of the speedometer displayed in the SpeedometerBox1 component is changed. For the arrow there will be width and the pen that renders arrow border. The shape of the arrow is also changed.
