public class QTextDocumentFragment
The QTextDocumentFragment class represents a piece of formatted text from a QTextDocument.
A QTextDocumentFragment is a fragment of rich text, that can be inserted into a QTextDocument. A document fragment can be created from a QTextDocument, from a QTextCursor's selection, or from another document fragment. Document fragments can also be created by the static functions, fromPlainText and fromHtml.
The contents of a document fragment can be obtained as plain text by using the toPlainText function, or it can be obtained as HTML with toHtml.

public QTextDocumentFragment(QTextCursor range)
Creates a QTextDocumentFragment from the range's selection. If the cursor doesn't have a selection, the created fragment is empty.
public QTextDocumentFragment()
Constructs an empty QTextDocumentFragment.
public QTextDocumentFragment(QTextDocumentFragment rhs)
Copy constructor. Creates a copy of the rhs fragment.
public QTextDocumentFragment(QTextDocument document)
Converts the given document into a QTextDocumentFragment. Note that the QTextDocumentFragment only stores the document contents, not meta information like the document's title.
Method Detail |
---|
public final boolean isEmpty()
Returns true if the fragment is empty; otherwise returns false.
public final java.lang.String toHtml(QByteArray encoding)
Returns the contents of the document fragment as HTML, using the specified encoding (e.g., "UTF-8", "ISO 8859-1").
public final java.lang.String toHtml()
public final java.lang.String toPlainText()
Returns the document fragment's text as plain text (i.e. with no formatting information).
public static QTextDocumentFragment fromHtml(java.lang.String html)
Returns a QTextDocumentFragment based on the arbitrary piece of HTML in the given html. The formatting is preserved as much as possible; for example, "<b>bold</b>" will become a document fragment with the text "bold" with a bold character format.
public static QTextDocumentFragment fromHtml(java.lang.String html, QTextDocument resourceProvider)
Returns a QTextDocumentFragment based on the arbitrary piece of HTML in the given html. The formatting is preserved as much as possible; for example, "<b>bold</b>" will become a document fragment with the text "bold" with a bold character format.
If the provided HTML contains references to external resources such as imported style sheets, then they will be loaded through the resourceProvider.
public static QTextDocumentFragment fromPlainText(java.lang.String plainText)
Returns a document fragment that contains the given plainText.
When inserting such a fragment into a QTextDocument the current char format of the QTextCursor used for insertion is used as format for the text.
public static QTextDocumentFragment fromNativePointer(QNativePointer nativePointer)
nativePointer
- the QNativePointer of which object should be returned.public static QNativePointer nativePointerArray(QTextDocumentFragment[] array)
array
- the array that the returned pointer will point to.
