Question

I’ve implemented some custom fields and would like to keep the look-and-feel consistent with the current Blackberry theme. So I would like the highlighting color of the fields to be consistent with the highlight color used throughout the BB apps.

How can I get the this color?

Edit: Apparently, there’s no way to get those kinds of colors from any API. So is there a work-around way to getting these colors?

What we can do is test colors on drawFocus method of some custom text field:

class TestField extends TextField {
    TestThemeListener mListener;
    public TestField(TestThemeListener listener) {
        super(EDITABLE | FOCUSABLE);
        setText("Hello this is a color test");
        setSelection(0, true, 10);
        mListener = listener;
    }
    protected void drawFocus(Graphics g, boolean on) {
        drawHighlightRegion(g, HIGHLIGHT_FOCUS, true, 0, 0, 50, 20);
        Bitmap bmp = new Bitmap(50, 20);
        Display.screenshot(bmp, 0, 0, 50, 20);
        int[] argbData = new int[1];
        bmp.getARGB(argbData, 0, 1, 0, 0, 1, 1);
        int focusColor = argbData[0];
        drawHighlightRegion(g, HIGHLIGHT_SELECT, true, 50, 0, 50, 20);
        Display.screenshot(bmp, 50, 0, 50, 20);
        argbData = new int[1];
        bmp.getARGB(argbData, 0, 1, 0, 0, 1, 1);
        int selectionColor = argbData[0];
        if (null != mListener) {
            mListener.themeTested(focusColor, selectionColor);
            mListener = null;
        }
    }
}

interface TestThemeListener {
    void themeTested(int focusColor, int selectionColor);
}

And use it on the screen:

class Scr extends MainScreen implements TestThemeListener {
    LabelField mSelectionColorName;
    LabelField mFocusColorName;
    public Scr() {
        add(new TestField(this));
    }
    public void themeTested(int focusColor, int selectionColor) {
        add(new LabelField("Theme colors (AARRGGBB)"));
        add(new LabelField("Focus : " + focusColor));
        Bitmap bmpF = new Bitmap(100, 20);
        Graphics gF = new Graphics(bmpF);
        gF.setColor(focusColor);
        gF.fillRect(0, 0, 100, 20);
        add(new BitmapField(bmpF));
        add(new LabelField("Selection : " + selectionColor));
        Bitmap bmpS = new Bitmap(100, 20);
        Graphics gS = new Graphics(bmpS);
        gS.setColor(selectionColor);
        gS.fillRect(0, 0, 100, 20);
        add(new BitmapField(bmpS));
    }
}
