Drop a pane on another pane in the interface.
A message dialog box will be displayed, giving you the option to create a layered pane.
If you have dropped a text pane, draw area pane, or term pane on a control pane, you will also have the option to create the object as a child of the control pane.
Click Cancel if you do not want to create a child pane or a layered pane.
The pane will be instantiated as a layered pane on top of the pane it was dropped on. Because it is the same size as the original pane, it will obscure the original pane completely. If you resize one of the layers of a layered pane, all panes are resized. See "To View Layered Panes" for instructions for viewing the layers of a layered pane.
Once you have completed the interface you may want to change the Size Policy of any panes in a layered pane to Fit Contents (the default value is Fixed, which should be retained until the interface is complete). Each of the panes might be a different size.
There is no direct way to unmake a layered pane, but you can accomplish the task by selecting one of the layers and choosing Cut from the Edit menu of the App Builder primary window or from one of the pop-up menus (displayed by pressing mouse button 3 in the interface or in the Module Browser).
If you want to save the layer you cut, select an empty window and choose Paste from the Edit menu. Repeat the Cut and Paste process until there are no more layers (this is easiest to see in the Browser). If you don't want to save the layers, choose Delete instead of Cut.
