Attempts to load the document at the given url with the specified type.
setSource() calls doSetSource. In Qt 5, setSource(const QUrl &url) was virtual. In Qt 6, doSetSource() is virtual instead, so that it can be overridden in subclasses.
Reimplemented from QTextBrowser.
Definition at line 59 of file aboutdialog.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 \l 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:
\table \header
