I'm new using Codename One. I'm doing an app which have a Form, that has a Tab component with 14 tabs inside, every tab has a gridlayout with 42 buttons, and I want to change a property in one button. The problem is that I don't know how to reach that button.

tabG.getContentPane().components.get(index)

tabG is the tab component, and I can reach the tab that I need, but after that I don't know how to reach the button index I want to change.

I tried

tabG.getContentPane().components.get(index).components.get(indexbutton)

But even can't compile this code.

enter image description here

I'll apprecciate any help.

    How did you create the components within the tab? In the creation code you need to prepare a strategy to find the component later. – Shai Almog Jan 23 '20 at 02:09

When you create the tab you need to prepare information to find the component later. E.g. if all tabs derive from the same class then just do something like:

MyBaseContainer cnt = (MyBaseContainer)tabs.getTabComponentAt(index);
Button theButtonINeed cnt.getMyImportantButton();

If this is more complicated you can use setName() or putClientProperty to prepare hints for you during form construction.

  • Thanks [Shai Almog](https://stackoverflow.com/users/756809/shai-almog). Now I realize, that the answer was to easy. But now, exists something like html id, and when is needed in javascript or jquery you can access with getElementById(id) or $("#id")? – Alejandro Vargas Jan 23 '20 at 20:05
