## com.trolltech.qt.webkit
Class QWebHistory

    java.lang.Object
      com.trolltech.qt.QSignalEmitter

              com.trolltech.qt.webkit.QWebHistory

All Implemented Interfaces:
  QtJambiInterface

    public final class QWebHistory

extends QtJambiObject

The `QWebHistory` class represents the history of a `QWebPage` Each `QWebPage` instance contains a history of visited pages that can be accessed by `QWebPage::history()`. `QWebHistory` represents this history and makes it possible to navigate it.

The history uses the concept of a current item, dividing the pages visited into those that can be visited by navigating back and forward using the `back()` and `forward()` functions. The current item can be obtained by calling `currentItem()`, and an arbitrary item in the history can be made the current item by passing it to `goToItem()`.

A list of items describing the pages that can be visited by going back can be obtained by calling the `backItems()` function; similarly, items describing the pages ahead of the current page can be obtained with the `forwardItems()` function. The total list of items is obtained with the `items()` function.

Just as with containers, functions are available to examine the history in terms of a list. Arbitrary items in the history can be obtained with `itemAt()`, the total number of items is given by `count()`, and the history can be cleared with the `clear()` function.

  `QWebHistoryItem`, `QWebHistoryInterface`, and `QWebPage`.
