Functions

◆ loadResource()

QVariant QTextDocumentWithImageResources::loadResource	(	int	type,
		const QUrl &	name
	)

protectedvirtual

Loads data of the specified type from the resource with the given name.

This function is called by the rich text engine to request data that isn't directly stored by QTextDocument, but still associated with it. For example, images are referenced indirectly by the name attribute of a QTextImageFormat object.

When called by Qt, type is one of the values of QTextDocument::ResourceType.

If the QTextDocument is a child object of a QTextEdit, QTextBrowser, or a QTextDocument itself then the default implementation tries to retrieve the data from the parent.

Reimplemented from QTextDocument.
