Member Function Documentation

virtual void Xfc::Gtk::EditableSignals::on_delete_text (  int  start_pos, int  end_pos )  [virtual]

Called when text is deleted from the widget by the user. Parameters: start_pos  The starting position. end_pos  The end position. The default handler for this signal will normally be responsible for deleting the text, so by overriding this method and either calling or not calling the parent class method, it is possible to modify the deleted text, or prevent it from being deleted entirely. The start_pos and end_pos parameters are interpreted as for delete_text()

virtual void Xfc::Gtk::EditableSignals::on_insert_text (  const String &  text, int *  position )  [virtual]

Called when text is inserted into the widget by the user. Parameters: text  The new text to insert. position  The position at which to insert the new text. Position is an in-out paramter. After the signal emission is finished, it should point after the newly inserted text. The default handler for this signal will normally be responsible for inserting the text, so by overriding this method and either calling or not calling the parent class method, it is possible to modify the inserted text, or prevent it from being inserted entirely.
