I would like to add some color to text my application.

I found the package
net.rim.device.api.ui.Color;


how to use the color in program

Please give some suggestions.

[Mark Rejhon]

Use the net.rim.device.api.ui.Graphics object, using RGB 0x00RRGGBB value.
Graphics.setColor(RGB);
To get the graphics object, use MainScreen.getGraphics()

// Do this inside a method in your class that implements MainScreen
Graphics g = this.getGraphics();
g.setColor(( red << 16 ) + ( green << 8 ) + blue); 
// Now you can draw your text. It will be the new color.

Or you can use values from the Color class, to set commonly used colors.

Graphics g = this.getGraphics();
g.setColor(Color.BLUE);

Thought this was exactly what I was looking for, but when trying:

inal Graphics g = this.getGraphics();
final int currentColor = g.getColor();

g.setColor( 255 << 16 ); // also tried g.setColor( Color.RED );

add( new RichTextField( "Error", RichTextField.NON_FOCUSABLE ) );
 
g.setColor( currentColor );

The RichTextField is still black :(
Is there anyway to set the color of the rich text field directly?

TIA, Ben

Override the paint method, and use call super.paint after setting the color. No other way I know of.

Hi genvej,

Try with the following code:

RichTextField colorField = new RichTextField("Hello") {
  // Override the paint method to set Color.
  public void paint(Graphics graphics) {
    graphics.setColor(Color.RED);
    super.paint(graphics);
  }
};
add(colorField);

Hope this will help!

Cheers,
ARIF

thx a bunch... however... Im also interested in changing the font, which your example doesnt let me do... i tried

public void paint(Graphics graphics) {
graphics.setFont(FieldFont());
graphics.setColor(Color.RED);
super.paint(graphics);
}

public static Font FieldFont(){
try {
FontFamily theFam = FontFamily.forName("BBCASUAL");
return theFam.getFont(net.rim.device.api.ui.Font.PLAIN, 31);
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
}
return null;
}

you tried:

colorField.setFont(FieldFont());


?

Try with the following code:

RichTextField colorField = new RichTextField("Hello") {
	// Override the paint method to set Font and Color.
	public void paint(Graphics graphics) {
	  setFont(FieldFont());
	  graphics.setColor(Color.RED);
	  super.paint(graphics);
	}
};
add(colorField);
