cadabra::ActionInsertText Class Reference


Add a text string (can be just a single character) at the point of the cursor.

This action is assumed to be triggered from a user change to the GUI cells, so will not update the GUI itself, only the underlying DTree. However, the revert method will need to update the GUI representation.
