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.
Document Source and Contents
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, "#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.
Navigation
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 CopperSpice 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.
