## Detailed Description

The QWebInspector class allows the placement and control of a QWebPage's inspector. The inspector allows you to see a page current hierarchy and loading statistics.

The QWebPage to be inspected is determined with the setPage() method.

A typical use of QWebInspector follows:

         // ...
         QWebPage *page = new QWebPage;
         // ...

         QWebInspector *inspector = new QWebInspector;
         inspector->setPage(page);

         connect(page, SIGNAL(webInspectorTriggered(QWebElement)), inspector, SLOT(show()));

Note: A QWebInspector will display a blank widget if either:

- page() is null
- QWebSettings::DeveloperExtrasEnabled is false

### Resources

This class acts mostly as a container and a controller for the inspector. Most of the resources needed by the inspector are owned by the associated QWebPage and are allocated the first time that:

- an element is inspected
- the QWebInspector is shown.

### Inspector configuration persistence

The inspector allows the user to configure some options through its interface (e.g. the resource tracking "Always enable" option). These settings are persisted automatically by QtWebKit using QSettings.

However since the QSettings object is instantiated using the empty constructor, QCoreApplication::setOrganizationName() and QCoreApplication::setApplicationName() must be called within your application to enable the persistence of these options.

## Member Function Documentation

### QWebInspector::QWebInspector ( QWidget * parent = 0 )

Constructs an empty QWebInspector with parent parent.

### QWebInspector::~QWebInspector ()

Destroys the inspector.

### bool QWebInspector::event ( QEvent * ev ) `[virtual]`

Reimplemented from QObject::event().

### void QWebInspector::hideEvent ( QHideEvent * event ) `[virtual protected]`

Reimplemented from QWidget::hideEvent().

### QWebPage * QWebInspector::page () const

Returns the inspected QWebPage. If no web page is currently associated, a null pointer is returned.

See also setPage().

### void QWebInspector::resizeEvent ( QResizeEvent * event ) `[virtual protected]`

Reimplemented from QWidget::resizeEvent().

### void QWebInspector::setPage ( QWebPage * page )

Sets the QWebPage to be inspected.

There can only be one QWebInspector associated with a QWebPage and vices versa.

Calling with page as null will break the current association, if any.

If page is already associated to another QWebInspector, the association will be replaced and the previous QWebInspector will have no page associated.

See also page().

### void QWebInspector::showEvent ( QShowEvent * event ) `[virtual protected]`

Reimplemented from QWidget::showEvent().

### QSize QWebInspector::sizeHint () const `[virtual]`

Reimplemented from QWidget::sizeHint().
