| 582 | \class QTextBrowser | - |
| 583 | \brief The QTextBrowser class provides a rich text browser with hypertext navigation. | - |
| 584 | | - |
| 585 | \ingroup richtext-processing | - |
| 586 | \inmodule QtWidgets | - |
| 587 | | - |
| 588 | This class extends QTextEdit (in read-only mode), adding some navigation | - |
| 589 | functionality so that users can follow links in hypertext documents. | - |
| 590 | | - |
| 591 | If you want to provide your users with an editable rich text editor, | - |
| 592 | use QTextEdit. If you want a text browser without hypertext navigation | - |
| 593 | use QTextEdit, and use QTextEdit::setReadOnly() to disable | - |
| 594 | editing. If you just need to display a small piece of rich text | - |
| 595 | use QLabel. | - |
| 596 | | - |
| 597 | \section1 Document Source and Contents | - |
| 598 | | - |
| 599 | The contents of QTextEdit are set with setHtml() or setPlainText(), | - |
| 600 | but QTextBrowser also implements the setSource() function, making it | - |
| 601 | possible to use a named document as the source text. The name is looked | - |
| 602 | up in a list of search paths and in the directory of the current document | - |
| 603 | factory. | - |
| 604 | | - |
| 605 | If a document name ends with | - |
| 606 | an anchor (for example, "\c #anchor"), the text browser automatically | - |
| 607 | scrolls to that position (using scrollToAnchor()). When the user clicks | - |
| 608 | on a hyperlink, the browser will call setSource() itself with the link's | - |
| 609 | \c href value as argument. You can track the current source by connecting | - |
| 610 | to the sourceChanged() signal. | - |
| 611 | | - |
| 612 | \section1 Navigation | - |
| 613 | | - |
| 614 | QTextBrowser provides backward() and forward() slots which you can | - |
| 615 | use to implement Back and Forward buttons. The home() slot sets | - |
| 616 | the text to the very first document displayed. The anchorClicked() | - |
| 617 | signal is emitted when the user clicks an anchor. To override the | - |
| 618 | default navigation behavior of the browser, call the setSource() | - |
| 619 | function to supply new document text in a slot connected to this | - |
| 620 | signal. | - |
| 621 | | - |
| 622 | If you want to load documents stored in the Qt resource system use | - |
| 623 | \c{qrc} as the scheme in the URL to load. For example, for the document | - |
| 624 | resource path \c{:/docs/index.html} use \c{qrc:/docs/index.html} as | - |
| 625 | the URL with setSource(). | - |
