NavigationBar

Description

The NavigationBar component is a side panel used to navigate properties of the active component and to control properties.

The NavigationBar component includes several tabs. Clicking tab headers expands internal panels with arbitrary contents. The component does not allow opening several tabs at the same time. Opening a tab closes the previous tab.

Comments

The component is implemented by the NavigationBar class.

The role of container for side panel can be acted by the SlidePanel component.

Example

The component looks as follows:

It the figure above all tabs of the navigation bar are collapsed. Tab headers can contain such controls, as ComboBox, Button, CheckBox, RadioButton. By default the CheckBox control is set for tab headers. This control is visible, but it can be hidden using the IsHeaderControlVisible property.

On opening a tab its internal panel is expanded and the tabs below are shifted downward:

If the navigation bar does not have enough space to expand an inner panel, the tabs are hidden starting from the lowermost tab, and a button with a drop-down menu named button appears.
