Guest: Guest	How can set the background color for status bar? Posted: Jul 17, 2008 2:56 AM
	How can set the background color for status bar? Using this code for Status Bar: LabelField statusField = new LabelField("Good Morning" ,LabelField.USE_ALL_WIDTH | LabelField.NON_FOCUSABLE | LabelField.HCENTER) { int _backgroundColour = Color.LIGHTGREEN; public void paint(Graphics g) { g.setBackgroundColor(Color.RED); g.clear(); super.paint(g); } }; Font defaultfont = Font.getDefault(); Font smallfont = defaultfont.derive(Font.PLAIN, 12); statusField.setFont(smallfont); setStatus(statusField);

When I ran the code you have above, my status background colour was red.  Is this not what you are seeing?  If so, please provide the BlackBerry model and handheld software version you are testing with.  You can find this under Options, About.

Or if you are trying to do something else, please elaborate. 

I was testing this in the BlackBerry Simulator included with the version 4.5.0 BlackBerry JDE (4.5.0.44).

I was testing this on JDE-4.1.0 (7290). Please tell me the solution for OS-4.1.

To do this in version 4.1, first call getColor and save the current colour.  Then call setColor, setting the colour to the colour you want to use for the background.  After that call call fillRect, starting at 0, 0 and going to the size of the field (use this.getWidth() and this.getHeight() to get this).  This should fill the entire field with your specified colour. 

To allow for drawing of the default field contents call setColor again, passing in the original color and then call super.paint.

Firstly Thanks MSohm. I used this scenario, it is very useful to me.But its tuck in one case.

Actually I am using statusBar to show the username, It can be long.So I am using this:

statusField = new LabelField(username,LabelField.FIELD_HCENTER|LabelField.HCENTER|LabelField.USE_ALL_HEIGHT|
        LabelField.NON_FOCUSABLE );

But when I am using this with paint():

statusField = new LabelField(" ",LabelField.FIELD_HCENTER|LabelField.HCENTER|LabelField.USE_ALL_HEIGHT|
        LabelField.NON_FOCUSABLE ){

      public void paint(Graphics g) {
                           int x=  g.getColor();
                           g.setColor(Color.LINEN);
                           g.fillRect(0,0,this.getWidth(),this.getHeight());
                           g.setColor(Color.BLUE);
                       super.paint(g);
                        }

};

It color only those area which is used by text. Please Help me to sort out this situation.

You can add the LabelField.USE_ALL_WIDTH style to your LabelField.

[BBDev]

 I had already tried with this style but problem is there when user name is long and we want to show this username in multiline then it doesn't show this in multiline. For this we removed LabelField.USE_ALL_WIDTH and used LabelField.USE_ALL_HEIGHT.

[MSohm]

Can you post a screenshot of what you see versus what you are trying to accomplish?  Long strings should wrap to the next line even with the LabelField.USE_ALL_WIDTH and used LabelField.USE_ALL_HEIGHT styles set.

class BCSColoredStatusField extends LabelField
{
    int color=Color.RED;
    int bgColor= Color.ALICEBLUE;
       
    /**

     * @param label String to be displayed
     */
    public BCSColoredStatusField(String label)       
    {
        super(label,LabelField.USE_ALL_WIDTH|LabelField.FIELD_HCENTER|LabelField.HCENTER|LabelField.USE_ALL_HEIGHT);
    }

    public BCSColoredStatusField()       
    {
        super("",LabelField.USE_ALL_WIDTH|LabelField.FIELD_HCENTER|LabelField.HCENTER|LabelField.USE_ALL_HEIGHT);
    }
   
    /**

    public void paint(Graphics g)
    {
        g.getBackgroundColor();
        g.setBackgroundColor(bgColor);
        g.clear();
       // g.fillRect(0,0,Graphics.getScreenWidth(),this.getHeight());
        g.getColor();
        g.setColor(color);
        //g.setFont(g.getFont().derive(Font.BOLD));           
        super.paint(g);

I'm not able to see the screenshots you posted.  Can you provide alternative image links?
