PySide.QtGui.QTextFrame class represents a frame in a PySide.QtGui.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() .
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 PySide.QtGui.QTextFrame.parentFrame() ，和 PySide.QtGui.QTextFrame.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 PySide.QtGui.QTextFrame.begin() and PySide.QtGui.QTextFrame.end() .
A frame also has a format (specified using PySide.QtGui.QTextFrameFormat ) which can be set with PySide.QtGui.QTextObject.setFormat() and read with PySide.QtGui.QTextObject.format() .
Text cursors can be obtained that point to the first and last valid cursor positions within a frame; use the PySide.QtGui.QTextFrame.firstCursorPosition() and PySide.QtGui.QTextFrame.lastCursorPosition() functions for this. The frame's extent in the document can be found with PySide.QtGui.QTextFrame.firstPosition() and PySide.QtGui.QTextFrame.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.

|---|
Creates a new empty frame for the text document .
| 返回类型： | PyObject |
|---|
| 返回类型： | PySide.QtGui.QTextFrame::iterator |
|---|
Returns an iterator pointing to the first document element inside the frame. Please see the document STL-style-Iterators 了解更多信息。
| 返回类型： |
|---|
Returns a (possibly empty) list of the frame's child frames.
| 返回类型： | PySide.QtGui.QTextFrame::iterator |
|---|
Returns an iterator pointing to the position past the last document element inside the frame. Please see the document STL 样式迭代器 了解更多信息。
| 返回类型： | PySide.QtGui.QTextCursor |
|---|
Returns the first cursor position inside the frame.
| 返回类型： | PySide.QtCore.int |
|---|
