Concatenate Javafx fx:Id

Question

I\'m kinda new to JavaFX and currently trying to do a Calendar application for a school project. I was wondering if there was a way to concatenate a fx:id

Answer 1

Various possible solutions:

1. You could use reflection, but that would be ugly and I wouldn't advise it.

2. Normally, if you have a lot of things, you put them in a collection like a list or array. The label will be a child of some layout pane, so you can get the children of the pane and lookup an item by index with something like:

   ((Label) parent.getChildren().get(0)).setText("Text");
   

3. If the label has been assigned a css id then you can use that to lookup the label.

   For example, in your FXML define:

   Then you can lookup the label using:

   String boxNum = "01";
   Label box = (Label) parent.lookup("#Box" + boxNum);
   

4. Just refer to the item by it's reference:

   @FXML private Label box01; 
   box01.setText("Test");
   

Aside: Please use camel case as per standard Java conventions.
