# Banner(3)

one line title bar

## NAME

Banner - one line title bar

## SYNOPSIS

**#include \<InterViews/banner.h\>**

## DESCRIPTION

A banner is an interactor that draws a one line title bar with optional left-justified, centered, and right-justified headings. The member variable *highlight* can be set to cause drawing to be performed with the foreground and background colors reversed.

The natural size of a banner depends on the size of its headings. Banners are infinitely stretchable horizontally, but fixed size vertically.

## PUBLIC OPERATIONS

- **Banner(char\* left, char\* middle, char\* right)**

  The *left* string will be left-justified, the *middle* string centered, and *right* string right-justified in the banner. A header can be omitted by passing a nil string.

- **void Update()**

  The strings can be set through the *left*, *middle*, and *right* member variables. The Update operation should be called after one or more of the strings is changed.
