QTextFrame Class Reference

Inheritance diagram for QTextFrame:

QTextObject QObject QTextTable

List of all members.


Detailed Description

The QTextFrame class represents a frame in a QTextDocument.

Text frames provide structure for the text in a document. They are used as generic containers for other document elements. Frames are usually created by using QTextCursor::insertFrame().

Each frame in a document consists of a frame start character, QChar(0xFDD0), followed by the frame's contents, followed by a frame end character, QChar(0xFDD1). The character formats of the start and end character contain a reference to the frame object's objectIndex.

Frames can be used to create hierarchical structures in rich text documents. Each document has a root frame (QTextDocument::rootFrame()), and each frame beneath the root frame has a parent frame and a (possibly empty) list of child frames. The parent frame can be found with parentFrame(), and the childFrames() function provides a list of child frames.

Each frame contains at least one text block to enable text cursors to insert new document elements within. As a result, the QTextFrame::iterator class is used to traverse both the blocks and child frames within a given frame. The first and last child elements in the frame can be found with begin() and end().

A frame also has a format (specified using QTextFrameFormat) which can be set with setFormat() and read with format().

Text cursors can be obtained that point to the first and last valid cursor positions within a frame; use the firstCursorPosition() and lastCursorPosition() functions for this. The frame's extent in the document can be found with firstPosition() and lastPosition().

You can iterate over a frame's contents using the QTextFrame::iterator class: this provides read-only access to its internal list of text blocks and child frames.
