A range of text that represents a selection.

Properties

• affinity(TextAffinity | None) –

  If the text range is collapsed and has more than one visual location (e.g., occurs

• base_offset(int | None) –

  The offset at which the selection originates.

• collapsed(bool | None) –

  Whether this range is empty (but still potentially placed inside the text).

• directional(bool | None) –

  Whether this selection has disambiguated its base and extent.

• end(int | None) –

  The next index after the characters in this range.

• extent_offset(int | None) –

  The offset at which the selection terminates.

• normalized(bool | None) –

  Whether the start of this range precedes the end.

• selection(str | None) –

  The text string that is selected.

• start(int | None) –

  The index of the first character in the range.

• valid(bool | None) –

  Whether this range represents a valid position in the text.

Properties

affinity

affinity: TextAffinity | None = None

If the text range is collapsed and has more than one visual location (e.g., occurs at a line break), which of the two locations to use when painting the caret.

base_offset

base_offset: int | None = None

The offset at which the selection originates.

collapsed

collapsed: bool | None = None

Whether this range is empty (but still potentially placed inside the text).

directional

directional: bool | None = None

Whether this selection has disambiguated its base and extent.

end

end: int | None = None

The next index after the characters in this range.

extent_offset

extent_offset: int | None = None

The offset at which the selection terminates.

normalized

normalized: bool | None = None

Whether the start of this range precedes the end.

selection

selection: str | None = None

The text string that is selected.

start

start: int | None = None

The index of the first character in the range.

valid

valid: bool | None = None

Whether this range represents a valid position in the text.
