Layer.LayerToClientX Property (ExGauge)

The LayerToClientX / LayerToClientY converts the (x,y)-point on the layer to control's view point. The LayerToClientX / LayerToClientY properties translate a point from the layer ( as it is moved or rotated ) to the control's view. For instance, you can display the current value of the control on the knob you are rotating. The RotamoveCenterX / RotamoveCenterY specifies the (x,y)-position of the layer's center, while the layer's drag operation is exDoRotamove. The OnDrag property indicates the action to be performed when the user drags the layer.

Any of the following properties can be used to display a HTML caption:

Caption property specifies the caption to be shown on the control's foreground.
ExtraCaption property specifies any extra caption to be shown on the control's foreground.
Foreground.Caption specifies the caption to be shown on the layer's foreground.
Foreground.ExtraCaption specifies any extra caption to be shown on the layer's foreground.

The following sample shows how you can use the LayerToClientX / LayerToClientY properties to display the layer's value on the knob:
