Layers

This window lists the layers of the currently edited form. When a layer is visible, an icon figuring an eye is displayed left to his name; on the other hand, when a layer is hidden, the icon is not displayed, and the controls belonging to this layer are grayed in the form editor. You can switch from one state to another by clicking the eye icon in this window.
An active layer is the layer on which controls are dropped when added to the form in the form editor. Only one layer can be active at a time. It is figured in this window by a solid arrow. To activate a different layer, simply click in the relevant cell of this window. As the active layer must be visible, activating a hidden layer also makes it visible.
For more information about using layers, please refer to the Layer property.
