Blackberry - how to define screen title height?

Question

Hi,

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.

Thanks

Answer 1

You'll want to use the setExtent method.

Answer 2

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

Answer 3

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.
