Blackberry - how to define screen title height?

Question

is there a possibility to define somehow title's height?

The main problem is a separator that is located under the actual title. So, possibly there is possibility to define somehow the separator's height.

API 4.5

Thanks

I'm assuming you're talking about the blackberry sdk, however knowing which api version would be helpful. — tplaner, Nov 19 '09 at 13:58

I have experienced this myself and the only way I know of to get around it is to override the (undocumented) method in MainScreen:

protected void applyTheme() {
    // leave this empty
}

This prevents the theme from setting colors and also seems to get rid of the separator between the title and main content.

Thanks for advice. But I am getting another interesting issues. If I do later screen layout change (like deleting some fields and adding new ones), the Theme looks like is returning back. – Lyubomyr Dutko Nov 20 '09 at 10:33
Hmm, I've never seen that happen before – Marc Novakowski Nov 20 '09 at 16:50

You'll want to use the setExtent method.

well, still I see separator. And it's height difficult to define. – Lyubomyr Dutko Nov 19 '09 at 14:21

To simply get title height try this:

class Scr extends MainScreen {
    public Scr() {
        setTitle("Hello!");
        Manager contentManager = getMainManager();
        Manager screenManager = contentManager.getManager();
        Field titleField = screenManager.getField(0);
        int height = titleField.getPreferredHeight();
        add(new LabelField(String.valueOf(height)));
    }
}

And to define title yourself, try to put custom field into setTitle

I have used following approach: 1. defined actual height of title (like the way you described) 2. retrieved height of separator: new SeparatorField().getPreferredHeight() 3. But still I am losing somewhere one pixel. – Lyubomyr Dutko Nov 19 '09 at 15:18
