15,353 Pointsquestion on ${controller.timerText}
Hey everyone,
When we have this code in our fxml file:
text="${controller.timerText}"
I believe we are binding the text of our fxml to that timerText in our controller file. However timerText doesn't exist in our controller file. There is mTimerText but that is a private field. Does it actually call the method below?:
public StringProperty timerTextProperty() {
return mTimerText;
}
or this one?
public String getTimerText() {
return mTimerText.get();
}
I believe one those two are being binded. However I cant seem to pinpoint which.
Also what was the reason we used StringProperty and SimpleStringProperty? In terms of, when would one use one and why?
Is it basically a string that has getters, setters, and that property method ^?
How come this is only in javaFX and not in normal java?
I feel that there is some sort of connect between StringProperty, binding in the fxml, and that property method^. If anyone could help clear up my confusion that would be great.
Thank you,
Kevin

15,353 PointsI rewatched it again and I believe I understand it now. We need to use a StringProperty in order to use the binding function. So when we write timerText, it automatically is referring to the timerTextProperty() method. And this so called JavaBeans is only used in javafx because we dont have fxml and therefore no binding in regular java.
