Single Visible Panel

In This Topic

The NSingleVisiblePanel class represents a panel in which only a single child widget is visible at a time. The visible child widget is specified by its index, via the NSingleVisiblePanel-VisibleIndex property.

The example below demonstrates how to create a single visible panel that contains 3 labels and instruct the panel to display the second label:

Single Visible Panel Example	Copy Code
NSingleVisiblePanel panel = new NSingleVisiblePanel(); panel.Add(new NLabel("This is label 0")); panel.Add(new NLabel("This is label 1")); panel.Add(new NLabel("This is label 2")); panel.VisibleIndex = 1;

Single Visible Panel Example

Copy Code

NSingleVisiblePanel panel = new NSingleVisiblePanel();
panel.Add(new NLabel("This is label 0"));
panel.Add(new NLabel("This is label 1"));
panel.Add(new NLabel("This is label 2")); 
panel.VisibleIndex = 1;

Properties and Events

The single visible panel provides the following properties:

VisibleIndex - the zero-based index of the currently visible child element. When the value of this property changes the VisibleIndexChanged event is fired.
VisibleElement - indicates the currently visible child element. When the value of this property changes, the VisibleIndex is automatically updated and the VisibleIndexChanged event is fired.
SizeToVisible - determines whether the panel should be sized to the visible element or to all contained elements.
