RussianLooks like I've found a solution to the problem of missing first entered symbols. Data can be entered into a cell as soon as the cell is in focus. There is no necessity to press Enter first or double click on a cell before data input.
Class CellField
//Text box cell
public class CellField {
private static StringBuffer text = new StringBuffer("");
public static String getText() {
return text.toString();
}
public static void setText(String text) {
CellField.text = new StringBuffer(text);
}
//true, if the length of more than one character
public static boolean isLessOrEqualOneSym(){
return CellField.text.length() <= 1;
}
//add character to the end of line
public static void addSymbol(String symbol){
text.append(symbol);
}
public static void clearText() {
setText("");
}
}
Class NewOrderCtrl(part of the code)
class public class NewOrderCtrl extends HBox implements Initializable {
@FXML private TableView<OrderItem> catalogTable;
@FXML private TableColumn<OrderItem, String> numCatalogColumn;
public void initialize(URL url, ResourceBundle resourceBundle) {
numCatalogColumn.setCellFactory(new Callback<TableColumn<OrderItem, String>, TableCell<OrderItem, String>>() {
@Override
public TableCell<OrderItem, String> call(TableColumn<OrderItem, String> orderItemStringTableColumn) {
return new EditingCell();
}
});
catalogTable.setOnKeyPressed(new EventHandler<KeyEvent>() {
@Override
public void handle(KeyEvent keyEvent) {
KeyCode keyCode = keyEvent.getCode();
if (keyCode == KeyCode.ENTER || keyCode == KeyCode.ESCAPE){
CellField.clearText();
}
if (keyCode.isDigitKey()) {
int row = catalogTable.getSelectionModel().getSelectedIndex();
catalogTable.edit(row, numCatalogColumn);
}
}
});
}
@FXML
private void onEditStart() {
CellField.clearText();
}
}
Class EditingCell
public class EditingCell extends TableCell<OrderItem, String> {

textField.setMinWidth(this.getWidth() - this.getGraphicTextGap() * 2);
textField.setOnKeyPressed(new EventHandler<KeyEvent>() {
@Override
public void handle(KeyEvent t) {
if (t.getCode() == KeyCode.ENTER) {
commitEdit(textField.getText());
EditingCell.this.getTableView().requestFocus();//why does it lose focus??
EditingCell.this.getTableView().getSelectionModel().selectBelowCell();
} else if (t.getCode() == KeyCode.ESCAPE) {
cancelEdit();
}
}
});
textField.setOnKeyReleased(new EventHandler<KeyEvent>() {
@Override
public void handle(KeyEvent t) {

CellField.addSymbol(t.getText());
} else {
CellField.setText(textField.getText());
}
textField.setText(CellField.getText());
textField.deselect();
textField.end();
textField.positionCaret(textField.getLength() + 2);//works sometimes
}
