Hi,
i've got an EditField in a HorizontalFieldManager. Now I want to change the Backgrundcolor of the EditField. I searched for it in the forum and found this Change EditField background color?

But the compiler sais that it's not a valid function for the EditField.

So how can I change the BG-Color?

thanks hibbert

I think the best way is to create a ColouredEditField that extends EditField.
Create additional constructors, with String text, int color; for example, and overwrite paint:

public void paint(Graphics graphics) {
    graphics.setBackgroundColor(color);
    graphics.clear();  
    super.paint(graphics);
}

You can also overwrite onFocus() to let it change its color while selected.

hth,
simon

thanks for the reply, i've tried this here:

//....
field = new myEdit("1","2");
//...
public class myEdit extends EditField {
         public boolean farbe;
    public myEdit(String label, String defaultString) {
        super(label, defaultString);
    }

    protected void layout(int width, int height) {
        setExtent(100, getFont().getHeight());
    }

    public void paint(Graphics graphics) {
            graphics.clear();
            graphics.setBackgroundColor(Color.CORNFLOWERBLUE);
            super.paint(graphics);
     }
    
    public void setFarbe(boolean ok) {
        farbe = ok;
    }


    public boolean isFocusable() {
        return true;
    }
} // end of myEdit

but there is still the white background...

add

super.paint(graphics);

to the paint method

ah ok, now i've found the little problem.
the EditField is in a HorizontalFieldManager, i have to add the paint method for the manager and not for the editField...

ok now it works, but there is still one problem left:
when i type a text the backgroundcolor switches back to white, so i have to paint the background again, but how?

thanks so far

public void onFocus(int direction)
{
_oldBackgroundColor = _backgroundColor; //backup
_backgroundColor = Color.BLUE;
invalidate();
}

public void onUnfocus()
{
_backgroundColor = _oldBackgroundColor;
invalidate();
}
