anchorPositionProperty back to summary

anchorPositionProperty	back to summary
public ReadOnlyProperty<TextPos> anchorPositionProperty() Anchor position property. The value can be null, indicating no selection. When the anchor position is `null`, the `selectionProperty` and the `caretPositionProperty` are also `null`. Note `selectionProperty()`, `anchorPositionProperty()`, and `caretPositionProperty()` are logically connected. When a change occurs, the anchor position is updated first, followed by the caret position, followed by the selection segment. Returns:ReadOnlyProperty<TextPos> the anchor position property Default Value null

public ReadOnlyProperty<TextPos> anchorPositionProperty()

extendSelection back to summary

extendSelection	back to summary
public void extendSelection(StyledTextModel model, TextPos pos) Extends selection to the specified position. Internally, the position will be normalized to be within the document boundaries. This method will issue a `setSelection(model, pos, pos)` call if the model instance is different from that passed before. While this method will accept the text position outside of the document range, the actual values of `anchorPositionProperty`, and `caretPositionProperty` must always remain within the valid range for the document. Parameters model:StyledTextModel the model, must be non-null pos:TextPos the new caret position, must be non-null
