Examples of org.pentaho.openformula.ui.model2.FormulaDocument.insertString()

org.pentaho.openformula.ui.model2.FormulaDocument.insertString()

Inserts a string of content. This will cause a DocumentEvent of type DocumentEvent.EventType.INSERT to be sent to the registered DocumentListers, unless an exception is thrown. The DocumentEvent will be delivered by calling the insertUpdate method on the DocumentListener. The offset and length of the generated DocumentEvent will indicate what change was actually made to the Document.

If the Document structure changed as result of the insertion, the details of what Elements were inserted and removed in response to the change will also be contained in the generated DocumentEvent. It is up to the implementation of a Document to decide how the structure should change in response to an insertion.

If the Document supports undo/redo, an UndoableEditEvent will also be generated. @param offset the offset into the document to insert the content >= 0. All positions that track change at or afterthe given location will move. @param str the string to insert @param a the attributes to associate with the inserted content. This may be null if there are no attributes. @throws BadLocationException the given insert position is not a valid position within the document @see DocumentEvent @see DocumentListener @see UndoableEditEvent @see UndoableEditListener
