Detailed Description

The QWebInspector class allows the placement and control of a QWebPage's inspector. The inspector can display a page's hierarchy, its loading statistics and the current state of its individual elements. It is mostly used by web developers.

The QWebPage to be inspected must be specified using the setPage() method.

A typical use of QWebInspector follows:

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

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

A QWebInspector can be made visible either programmatically using setVisible(), or by the user through the attached QWebPage's context menu.

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

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 user interface (e.g. the resource tracking "Always enable" option). These settings will be persisted automatically by QtWebKit only if your application previously called QCoreApplication::setOrganizationName() and QCoreApplication::setApplicationName(). See QSettings's default constructor documentation for an explanation of why this is necessary.

Member Function Documentation

QWebInspector::QWebInspector ( QWidget * parent = 0 )

Constructs an unbound QWebInspector with parent as its parent.

QWebInspector::~QWebInspector ()

Destroys the inspector.

void QWebInspector::closeEvent ( QCloseEvent * event ) [virtual protected]

Reimplemented from QWidget::closeEvent().

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 )

Bind this inspector to the QWebPage to be inspected.

Notes:

  • There can only be one QWebInspector associated with a QWebPage and vice versa.
  • Calling this method with a null page 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 become unbound

See also page().

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

Reimplemented from QWidget::showEvent().

QSize QWebInspector::sizeHint () const [virtual]

Reimplemented from QWidget::sizeHint().
