Go to the specific tab when backed from a screen
How can I go to a specific tab when backed from a screen? Lets say I am in newForm screen and when I touch the back button, I'll go to Home screen. There are 4 tabs in homeScreen and I want to go to 3rd tab as soon as I've backed to home.
Home class
Tabs tabs = new Tabs(Component.BOTTOM);
tabs.addTab("Home", icon, homeContainer);
tabs.addTab("Home1", icon1, home1Container);
tabs.addTab("Home2", icon2, home2Container);
tabs.addTab("Home3", icon3, home3Container);
add(BorderLayout.CENTER, tabs);
Button newForm = new Button("New Form");
newForm.addActionListener(e=>{
new NewForm(res).show();
});
NewForm class:
Command back = new Command("") {
@Override
public void actionPerformed(ActionEvent ev) {
new Home(res).show();
}
};
.setBackCommand(back);

I would suggest keeping an instance of the Home form and just using Home.getInstance().showBack(). This will mean that the last selected tab would remain "as is".
If you want to select a specific index use: tabs.setSelectedIndex(idx, false).
Notice that the index starts at 0.
