JavaFX如何将TextProperty绑定为附加到TextField（未设置）

Question

I have a TextField named eventLog with binded StringProperty from the other Class. This class looks like this:

public class LogInfo {
    private static StringProperty logData = new SimpleStringProperty();

    public static StringProperty logDataProperty() {
        return logData;
    }

    public static void setLogData(String data) {
        logData.set(data);
    }

    public static String getLogData() {
        return logData.get();
    }
}

On my JavaFX controller class it's started like this:

@Override
    public void initialize(URL arg0, ResourceBundle arg1) {
        eventLog.textProperty().bind(LogInfo.logDataProperty());
        LogInfo.setLogData("Some informations");
    }

It's working great, but each time I use LogInfo.setLogData(String data) it's added to my TextField and clearing previous info, I need to append it. Is there any way to append instead of adding and clearing TextField ?

Since you can play with the output of the StringProperty, i recommend you this way:

public static void setLogData(String data) {
    logData.set(logData.get()+data);
}
