- \class QWebInspector
- \since 4.6
- \inmodule QtWebKit
- \brief 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:
-
- \snippet webkitsnippets/qtwebkit_qwebinspector_snippet.cpp 0
-
- 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:
- \list
- \li page() is null
- \li QWebSettings::DeveloperExtrasEnabled is false
- \endlist
-
- \section1 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:
- \list
- \li an element is inspected
- \li the QWebInspector is shown.
- \endlist
-
- \section1 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.
