详细描述 ¶

此类扩展 QTextEdit (以只读模式)，添加一些导航功能，以便用户可以在超文本文档中跟随链接。

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 setReadOnly() to disable editing. If you just need to display a small piece of rich text use QLabel .

文档源和内容 ¶

The contents of QTextEdit are set with setHtml() or setPlainText() ，但 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() 信号。

导航 ¶

QTextBrowser 提供 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() .

参数: arg__1 – bool

PySide2.QtWidgets.QTextBrowser. backwardHistoryCount ( ) ¶

返回类型: int

PySide2.QtWidgets.QTextBrowser. doSetSource ( name [ , type=QTextDocument.UnknownResource ] ) ¶

参数

name – QUrl
type – ResourceType

Attempts to load the document at the given url with the specified type .

setSource() calls . In Qt 5, setSource (const QUrl &url) was virtual. In Qt 6, is virtual instead, so that it can be overridden in subclasses.

PySide2.QtWidgets.QTextBrowser. forward ( ) ¶: Changes the document displayed to the next document in the list of documents built by navigating links. Does nothing if there is no next document.

`i` > 0	`forward()` history

												backaction.setToolTip(browser.historyTitle(-1))

PySide2.QtWidgets.QTextBrowser. historyUrl ( arg__1 ) ¶

参数: arg__1 – int
返回类型: QUrl

Returns the url of the HistoryItem.

Input	返回
`i` < 0	`backward()` history
`i` == 0	current, see `source()`
`i` > 0	`forward()` history

PySide2.QtWidgets.QTextBrowser. home ( ) ¶: Changes the document displayed to be the first document from the history.

PySide2.QtWidgets.QTextBrowser. isBackwardAvailable ( ) ¶

返回类型: bool

返回 true if the text browser can go backward in the document history using backward() .

PySide2.QtWidgets.QTextBrowser. setSource ( name , type ) ¶

参数

name – QUrl
type – ResourceType

Attempts to load the document at the given url with the specified type .

若 type is UnknownResource (the default), the document type will be detected: that is, if the url ends with an extension of .md , .mkd or .markdown , the document will be loaded via setMarkdown() ; otherwise it will be loaded via setHtml() . This detection can be bypassed by specifying the type explicitly.
