The QTextBrowser class provides a rich text browser with hypertext navigation.
This class extends QTextEdit (in read-only mode), adding some navigation functionality so that users can follow links in hypertext documents.
If you want to provide your users with an editable rich text editor, use QTextEdit. If you want a text browser without hypertext navigation use QTextEdit, and use QTextEdit::setReadOnly() to disable editing. If you just need to display a small piece of rich text use QLabel.
The contents of QTextEdit are set with setHtml() or setPlainText(), but QTextBrowser also implements the setSource() function, making it possible to use a named document as the source text. The name is looked up in a list of search paths and in the directory of the current document factory.
If a document name ends with an anchor (for example, "\c #anchor"), the text browser automatically scrolls to that position (using scrollToAnchor()). When the user clicks on a hyperlink, the browser will call setSource() itself with the link's href value as argument. You can track the current source by connecting to the sourceChanged() signal.
QTextBrowser provides backward() and forward() slots which you can use to implement Back and Forward buttons. The home() slot sets the text to the very first document displayed. The anchorClicked() signal is emitted when the user clicks an anchor. To override the default navigation behavior of the browser, call the setSource() function to supply new document text in a slot connected to this signal.
If you want to load documents stored in the Qt resource system use qrc as the scheme in the URL to load. For example, for the document resource path :/docs/index.html use qrc:/docs/index.html as the URL with setSource(). To access local files, use file as the scheme in the URL.

signal |
This signal is emitted when the user clicks an anchor.
The URL referred to by the anchor is passed in link.
Note that the browser will automatically handle navigation to the location specified by link unless the openLinks property is set to false or you call setSource() in a slot connected. This mechanism is used to override the default navigation features of the browser.

This signal is emitted when the availability of forward() changes.
available is true after the user navigates backward() and false when the user navigates or goes forward().

Convenience signal that allows connecting to a slot that takes just a QString, like for example QStatusBar's message().
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Reimplemented from QTextEdit.
Definition at line 963 of file qtextbrowser.cpp.
This function is called when the document is loaded and for each image in the document.
The type indicates the type of resource to be loaded. An invalid QVariant is returned if the resource cannot be loaded.
The default implementation ignores type and tries to locate the resources by interpreting name as a file name. If it is not an absolute path it tries to find the file in the paths of the searchPaths property and in the same directory as the current source. On success, the result is a QVariant that stores a QByteArray with the contents of the file.
If you reimplement this function, you can return other QVariant types. The table below shows which variant types are supported depending on the resource type:
| ResourceType | QVariant::Type |
| QTextDocument::HtmlResource | QString or QByteArray |
| QTextDocument::ImageResource | QImage, QPixmap or QByteArray |
| QTextDocument::StyleSheetResource | QString or QByteArray |

signal |
This signal is emitted when the source has changed, src being the new source.
Source changes happen both programmatically when calling setSource(), forward(), backword() or home() or when the user clicks on links or presses the equivalent key sequences.

Specifies whether QTextBrowser should automatically open links to external sources using QDesktopServices::openUrl() instead of emitting the anchorClicked signal.
Links are considered external if their scheme is neither file or qrc.
The default value is false.

This property specifies whether QTextBrowser should automatically open links the user tries to activate by mouse or keyboard.
Regardless of the value of this property the anchorClicked signal is always emitted.
The default value is true.

the search paths used by the text browser to find supporting content
QTextBrowser uses this list to locate images and documents.
By default, this property contains an empty string list.

the name of the displayed document.
This is a an invalid url if no document is displayed or if the source is unknown.
When setting this property QTextBrowser tries to find a document with the specified name in the paths of the searchPaths property and directory of the current source, unless the value is an absolute file path. It also checks for optional anchors and scrolls the document accordingly
If the first tag in the document is <qt type="detail">, the document is displayed as a popup rather than as new document in the browser window itself. Otherwise, the document is displayed normally in the text browser with the text set to the contents of the named document with setHtml().
By default, this property contains an empty URL.
