NavigationPane Guide

The NavigationPane is a highly versatile control. This article describes some of its properties and functions.

TitleBar

The TitleBar is the area at the top of the NavigationPane. Its main area displays the TitleBarItems associated with the currently displayed NavigationPanePanel. It also has three buttons, each of which can be shown or hidden as required:

	ExpandTitleBarButton	Toggles the Expanded property of the TitleBar
	ExpandPaneButton	Toggles the Expanded property of the NavigationPane
	ClosePaneButton	Sets the Visible property of the NavigationPane to false

The TitleBar has a collection of TitleBarExpandPanels, which are container areas that are displayed below the TitleBar and above the NavigationPanePanel when the Expanded property of the TitleBar is true. Only one TitleBarExpandPanel can be displayed at a time, which is determined by the SelectedExpandPanelIndex of the TitleBar.

NavigationPanePanel (Panels collection)

A NavigationPanePanel is the main container area of the NavigationPane. Each NavigationPanePanel has a button which is displayed at the bottom of the NavigationPane. The NavigationPane can contain multiple NavigationPanePanels but only one can be displayed at a time, which is determined by the SelectedPanel and SelectedPanelIndex properties of the NavigationPane. The button of the currently selected NavigationPanePanel is shown in a checked state.

Each NavigationPanePanel has a collection of TitleBarItems, which are displayed in the TitleBar area when the NavigationPanePanel is selected, and a collection of VerticalBarItems which are displayed in place of the NavigationPanePanel when the NavigationPanePanel is selected and NavigationPane Expanded property is false. Both of these components have image and text properties. The VerticalBarItems also have a style property which determines if a Popup panel should be displayed when it is clicked. A Popup panel is a resizable area that displays the contents of the associated NavigationPanePanel.
