D dilettante Active Member Licensed User Longtime User Dec 19, 2013 #1 Sorry if this duplicates another question, but I didn't find it. Tab order seems to be a function of declaration sequence within the .fxml file, so I guess you can hack around in the raw XML to change it when needed. But figuring out what determines which Node gets focus when a Form is loaded & shown escapes me. The Oracle docs say: When a Scene is created, the system gives focus to a Node whose focusTraversable variable is true and that is eligible to receive the focus, unless the focus had been set explicitly via a call to requestFocus(). Click to expand... So it seems to be "random" (even though consistent once a Form and View have been created), though the rules appear to vary from Form to Form. You almost have to add a requestFocus() call to every chunk of Form-initialization code in your programs. One thing that appears to be true is that a TextField gets precedence over a Button, i.e. if you have one of each on a Layout the TextField will always have focus when the Form is loaded and shown. This is probably more of a JavaFX issue than a B4J issue but they are hard to separate when you are using B4J. But to sum up, my question is: Does anybody know where to find comprehensive rules regarding focus and how to manage it at design time?

Erel B4X founder Staff member Licensed User Longtime User Dec 20, 2013 #3 As BPak wrote you can change the order of nodes in the builder. This should change the tab order. Upvote 0
D dilettante Active Member Licensed User Longtime User Dec 20, 2013 #4 Yes, I saw that and it works fine for the tab order, but I still can't make a Button have focus (even when first in the list) when the Form 1st opens without setting focus at runtime. The first TextField always gets focus first. Upvote 0
