详细描述 ¶

PySide.QtWebKit.QWebView class provides a widget that is used to view and edit web documents.

PySide.QtWebKit.QWebView is the main widget component of the QtWebKit web browsing module. It can be used in various applications to display web content live from the Internet.

A web site can be loaded onto PySide.QtWebKit.QWebView 采用 PySide.QtWebKit.QWebView.load() function. Like all Qt widgets, the PySide.QtGui.QWidget.show() function must be invoked in order to display PySide.QtWebKit.QWebView . The snippet below illustrates this:

										view = QWebView(parent)
view.load(QUrl("http://qt.nokia.com/"))
view.show()
										
									

另外， PySide.QtWebKit.QWebView.setUrl() can also be used to load a web site. If you have the HTML content readily available, you can use PySide.QtWebKit.QWebView.setHtml() 代替。

PySide.QtWebKit.QWebView.loadStarted() signal is emitted when the view begins loading. The PySide.QtWebKit.QWebView.loadProgress() signal, on the other hand, is emitted whenever an element of the web view completes loading, such as an embedded image, a script, etc. Finally, the PySide.QtWebKit.QWebView.loadFinished() signal is emitted when the view has loaded completely. It's argument - either true or false - indicates load success or failure.

PySide.QtWebKit.QWebView.page() function returns a pointer to the web page object. See Elements of QWebView for an explanation of how the web page is related to the view. To modify your web view's settings, you can access the PySide.QtWebKit.QWebSettings object with the PySide.QtWebKit.QWebView.settings() function. With PySide.QtWebKit.QWebSettings , you can change the default fonts, enable or disable features such as JavaScript and plugins.

可以访问 HTML 文档的标题采用 PySide.QtWebKit.QWebView.title() property. Additionally, a web site may also specify an icon, which can be accessed using the PySide.QtWebKit.QWebView.icon() property. If the title or the icon changes, the corresponding PySide.QtWebKit.QWebView.titleChanged() and PySide.QtWebKit.QWebView.iconChanged() signals will be emitted. The PySide.QtWebKit.QWebView.textSizeMultiplier() property can be used to change the overall size of the text displayed in the web view.

If you require a custom context menu, you can implement it by reimplementing PySide.QtGui.QWidget.contextMenuEvent() and populating your PySide.QtGui.QMenu with the actions obtained from PySide.QtWebKit.QWebView.pageAction() . More functionality such as reloading the view, copying selected text to the clipboard, or pasting into the view, is also encapsulated within the PySide.QtGui.QAction objects returned by PySide.QtWebKit.QWebView.pageAction() . These actions can be programmatically triggered using PySide.QtWebKit.QWebView.triggerPageAction() . Alternatively, the actions can be added to a toolbar or a menu directly. PySide.QtWebKit.QWebView maintains the state of the returned actions but allows modification of action properties such as PySide.QtGui.QAction.text() or PySide.QtGui.QAction.icon() .

A PySide.QtWebKit.QWebView can be printed onto a PySide.QtGui.QPrinter 使用 print() function. This function is marked as a slot and can be conveniently connected to PySide.QtGui.QPrintPreviewDialog ‘s PySide.QtGui.QPrintPreviewDialog.paintRequested() 信号。

If you want to provide support for web sites that allow the user to open new windows, such as pop-up windows, you can subclass PySide.QtWebKit.QWebView and reimplement the PySide.QtWebKit.QWebView.createWindow() 函数。

QWebView 元素 ¶

PySide.QtWebKit.QWebView consists of other objects such as PySide.QtWebKit.QWebFrame and PySide.QtWebKit.QWebPage . The flowchart below shows these elements are related.

注意

It is possible to use PySide.QtWebKit.QWebPage and PySide.QtWebKit.QWebFrame , without using PySide.QtWebKit.QWebView , if you do not require PySide.QtGui.QWidget attributes. Nevertheless, QtWebKit depends on QtGui , so you should use a PySide.QtGui.QApplication 而不是 PySide.QtCore.QCoreApplication .

When using this method, WebKit assumes that external resources such as JavaScript programs or style sheets are encoded in UTF-8 unless otherwise specified. For example, the encoding of an external script can be specified through the charset attribute of the HTML script tag. Alternatively, the encoding can also be specified by the web server.

This is a convenience function equivalent to setContent(html, “text/html”, baseUrl).

警告

This function works only for HTML, for other mime types (i.e. XHTML, SVG) PySide.QtWebKit.QWebView.setContent() should be used instead.
