Detailed Description#
A text fragment describes a piece of text that is stored with a single character format. Text in which the character format changes can be represented by sequences of text fragments with different formats.
If the user edits the text in a fragment and introduces a different character format, the fragment’s text will be split at each point where the format changes, and new fragments will be created. For example, changing the style of some text in the middle of a sentence will cause the fragment to be broken into three separate fragments: the first and third with the same format as before, and the second with the new style. The first fragment will contain the text from the beginning of the sentence, the second will contain the text from the middle, and the third takes the text from the end of the sentence.
A fragment’s text and character format can be obtained with the text() and charFormat() functions. The length() function gives the length of the text in the fragment. position() gives the position in the document of the start of the fragment. To determine whether the fragment contains a particular position within the document, use the contains() function.
- class PySide6.QtGui.QTextFragment#
PySide6.QtGui.QTextFragment(o)
- Parameters:
Creates a new empty text fragment.
Copies the content (text and format) of the other text fragment to this text fragment.
- PySide6.QtGui.QTextFragment.charFormat()#
- Return type:
Returns the text fragment’s character format.

- PySide6.QtGui.QTextFragment.charFormatIndex()#
- Return type:
int
Returns an index into the document’s internal list of character formats for the text fragment’s character format.

- PySide6.QtGui.QTextFragment.contains(position)#
- Parameters:
position – int
- Return type:
bool
Returns true if the text fragment contains the text at the given position in the document; otherwise returns false.
- PySide6.QtGui.QTextFragment.glyphRuns([from=-1[, length=-1]])#
- Parameters:
from – int
length – int
- Return type:
.list of QGlyphRun
Returns the glyphs corresponding to len characters of this text fragment starting at position pos. The positions of the glyphs are relative to the position of the QTextBlock ‘s layout.
If pos is less than zero, it will default to the start of the QTextFragment . If len is less than zero, it will default to the length of the fragment.

- PySide6.QtGui.QTextFragment.__eq__(o)#
- Parameters:
- Return type:
bool
