Back button doubles toolbar dimension

[P5music]

I added the back functionality to forms that call one another

A->B->C

I put a button on the toolbar, otherwise the back command is not visible.

Button backButton=new Button("back");
Command backCommand=new Command("Back") {
    @Override
    public void actionPerformed(ActionEvent evt) {
        mainForm.showBack();
    }
};

backButton.setCommand(backCommand);
getToolbar().add(BorderLayout.WEST,backButton);

but the result is a doubled toolbar, as you can see in the attached image.

And you can also see that the message is "Back", not "back".

So it's not the Button displayed there, but if I do not add it, nothing is displayed. It's strange.

What's wrong?

Thanks in advance

Use toolbar.setBackCommand(). Or toolbar.addMaterialCommand* methods etc.

With only this code too I get the double-sized toolbar, as you can see in the attached image.

Command backCommand=new Command("Back") {
    @Override
    public void actionPerformed(ActionEvent evt) {

        parentForm.showBack();
    }
};

getToolbar().setBackCommand(backCommand);

Is this on iOS. I think your referring to the StatusBar. On iOS you need to render the area where the time/clock etc. are drawn. Where the notch will hide your title anyway. So we have an implicit padding called StatusBar. on the top of the UI.
