Ich verwende Spinner in meiner JavaFX
Anwendung. Ich habe unter listener
zu meinem Spinner hinzugefügt, um immer den aktualisierten Wert von Spinner
zu erhalten. Diese Spinner
ist doppelt Wert Spinner.JavaFX Spinner werfen IllegalArgumentException: Der Start muss <= das Ende sein
lengthOverAllSpinner.getEditor().textProperty().addListener((observable, oldValue, newValue) -> {
try {
lengthOverAllSpinner.getValueFactory().setValue(Double.parseDouble(newValue));
} catch (NumberFormatException e) {
lengthOverAllSpinner.getValueFactory().setValue(Double.parseDouble(oldValue));
}
});
Aber wenn ich versuche, meine Spinner von GUI (zum Beispiel Stromwert 340,23) zu bearbeiten und wenn ich Backspace drücken und entfernen Sie den Wert bis Dezimalstelle unter Ausnahme ausgelöst wird, aber ich habe den immer aktualisierten Wert. Keine Ahnung, warum diese Ausnahme kommt. Bitte helfen:
