For some reason, when you use the keyboard to * enter a cell (tab, enter, arrow keys, etc), the first character that you type * after entering the field is NOT passed through the KeyListener mechanism * where we have the special handling in the DataTypes. Instead, it is passed * through the KeyMap and Action mechanism, and the default Action on the * JTextField is to add the character to the end of the existing text, or if it is delete * to delete the last character of the existing text. In most cases, this is ok, but * there are three special cases of which we only handle two here: * - If the data field currently contains "<null>" and the user types a character, * we want that character to replace the string "<null>", which represents the * null value. In this case we process the event normally, which usually adds * the char to the end of the string, then remove the char afterwards. * We take this approach rather than just immediately replacing the "<null>" * with the char because there are some chars that should not be put into * the editable text, such as control-characters. * - If the data field contains "<null>" and the user types a delete, we do not * want to delete the last character from the string "<null>" since that string * represents the null value. In this case we simply ignore the user input. * - Whether or not the field initially contains null, we do not run the input validation * function for the DataType on the input character. This means that the user * can type an illegal character into the field. For example, after entering an * Integer field by typing a tab, the user can enter a letter (e.g. "a") into that * field. The normal keyListener processing prevents that, but we cannot * call it from this point. (More accurately, I cannot figure out how to do it * easilly.) Thus the user may enter one character of invalid data into the field. * This is not too serious a problem, however, because the normal validation * is still done when the user leaves the field and it SQuirreL tries to convert * the text into an object of the correct type, so errors of this nature will still * be caught. They just won't be prevented. */ public void processKeyEvent(KeyEvent e) { // handle special case of delete with <null> contents if (e.getKeyChar() == '\b' && getEditorComponent() != null && ((RestorableJTextField)getEditorComponent()).getText().equals("<null>") ) { //ignore the user input return; } // generally for KEY_TYPED this means add the typed char to the end of the text, // but there are some things (e.g. control chars) that are ignored, so let the // normal processing do its thing super.processKeyEvent(e); // now check to see if the original contents were <null> // and we have actually added the input char to the end of it if (getEditorComponent() != null) { if (e.getID() == KeyEvent.KEY_TYPED && ((RestorableJTextField)getEditorComponent()).getText().length() == 7) { // check that we did not just add a char to a <null> if (((RestorableJTextField)getEditorComponent()).getText().equals("<null>"+e.getKeyChar())) { // replace the null with just the char ((RestorableJTextField)getEditorComponent()).updateText(""+e.getKeyChar()); } } } } /* * When user leaves a cell after editing it, the contents of * that cell need to be converted from a string into an * object of the appropriate type before updating the table. * However, when the call comes from the Popup window, the data * has already been converted and validated. * We assume that a String being passed in here is a value from * a text field that needs to be converted to an object, and * a non-string object has already been validated and converted. */ public void setValueAt(Object newValueString, int row, int col) { if (!
