Desktop Page Panel
From Xojo Documentation
The Page Panel is an invisible control that allows you to group controls into multiple panels (or pages). Only the controls on the current panel are visible. This control has no tabs or other navigation widgets, nor does it have a visible border. Only the controls on each panel are visible. You are responsible for providing the method of navigating from one panel to another, which you do by changing the SelectedPanelIndex property programmatically.
In the Layout Editor, you navigate among panels in a Page Panel control using the widget at the bottom of the control. There are two ways to navigate between existing panels. Click in the center of the navigation widget to get access the “Go to Page” command that shows a drop-down menu of page numbers. Select a page number from this menu to go directly to the panel on that page. Or, click the left or right arrows to the left or right of the page number in the widget to go to the next or previous panel.
You add, remove, and reorder panels using the Panel Editor. You can display the Panel editor by clicking the Edit button next to the Panels property in the Inspector of a Page Panel. In addition to using the Up/Down buttons to reorder the panels, you can also drag them into the order you want.
