Detailed Description#

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 insertFrame() .

Frames can be used to create hierarchical structures in rich text documents. Each document has a root frame ( 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 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 iterator class: this provides read-only access to its internal list of text blocks and child frames.

__init__(doc)#

Parameters:: doc – QTextDocument

Creates a new empty frame for the text document.

__iter__()#

Return type:: object

end()

childFrames()#

Return type:: .list of QTextFrame

Returns a (possibly empty) list of the frame’s child frames.
