Question

How can I set focus on next component in the form? For example:

        Button button1 = new Button("Button1");
        button1.addClickHandler(new ClickHandler() {
            public void onClick(ClickEvent event) {
                button1.???
            }
        });

I dont know what next components are, and I dont want to know.
In a hard way I would need to check if next components exist. Next step is check if they are focusable or not. For example next component maight be a button (or other input), but it could be placed in <table><tbody><tr><td><button></td></tr></tbody></table> so i would need to do that in recursive way.
Isn t there a simpler way?

将你的所有组成部分都列入一个阵列,然后在座标出你的位置,并将下个项目放在阵列中。

阵列。

你们不得不在启动时建立阵列,否则,无论文件是谁,你都会控制项目顺序。
