Parameters:

lines (Iterable[Optional[str]])

Return type:

QgsTextDocument

static fromTextAndFormat(lines: Iterable[str | None], format: QgsTextFormat) → QgsTextDocument[source]

splitLines(self, wrapCharacter: str | None, autoWrapLength: int = 0, useMaxLineLengthWhenAutoWrapping: bool = True)[source]

Splits lines of text in the document to separate lines, using a specified wrap character (wrapCharacter) or newline characters.

The autoWrapLength argument can be used to specify an ideal length of line to automatically wrap text to (automatic wrapping is disabled if autoWrapLength is 0). This automatic wrapping is performed after processing wrapping using wrapCharacter. When auto wrapping is enabled, the useMaxLineLengthWhenAutoWrapping argument controls whether the lines should be wrapped to an ideal maximum of autoWrapLength characters, or if False then the lines are wrapped to an ideal minimum length of autoWrapLength characters.

Parameters:

  • wrapCharacter (Optional[str])

  • autoWrapLength (int = 0)

  • useMaxLineLengthWhenAutoWrapping (bool = True)

toPlainText(self) → List[str][source]

Returns a list of plain text lines of text representing the document.

Return type:

List[str]
