How to use SystemColor class?

[Gokul20]

Hello friends,

I just started to learn the java class concepts. While this I am not able to get use of SystemColor class. I don't know anything about the SystemColor class methods as well as it's constructors. I have gone through various books, but didn't get proper details. If you know anything about the SystemColor class of java, then please let me aware about the same. I am waiting for your reply.

Hi,

The SystemColor class is basically used to encapsulate symbolic colors representing the color of native GUI objects. This java class is hired from the package 'java.awt.Color'. It extends all the properties of 'Color' class. In order to compare the "current" RGB value of a SystemColor object with a non-symbolic Color object, getRGB should be used rather than equals.

Example of SystemColor class of java:

import java.awt.Color;
import java.awt.SystemColor;

public class SystemColorDM 
{
  public static void main(String[] abg) 
{
    Color[] sysColor1 = new Color[]
{    
       SystemColor.menuText,
        SystemColor.scrollbar,
        SystemColor.text,      
        SystemColor.controlDkShadow,
        SystemColor.desktop,
        SystemColor.inactiveCaption,
        SystemColor.inactiveCaptionBorder,
        SystemColor.window,
        SystemColor.windowBorder,
        SystemColor.windowText};
        SystemColor.inactiveCaptionText,
        SystemColor.info,
        SystemColor.infoText,
        SystemColor.menu,
        SystemColor.textHighlight,
        SystemColor.textHighlightText,
        SystemColor.textInactiveText,
        SystemColor.textText,
        
    
    for(Color c1: sysColor1){
       System.out.println(c1); 
       }
  }
}

Hello friend,

Following java code will give you something idea about the SystemColor class:

java.awt.SystemColor
using System.Windows.Forms;
using System.Windows;

class SystemColorSample

 {
    public static void Main(String dh[]) 
{
        Application.Run(new HundredPixelsSquare());
    }
    public HundredPixelsSquare() 
{
        Text1 = "Pixels Square";
        ResizeRedraw = true;
    }
    protected override void OnPaint(PaintEventArgs pea1) 
{
        DoPage(pea1.Graphics, ForeColor, ClientSize.Width, ClientSize.Height);
    }
    protected void DoPage(Graphics grfx1, Color clr, int cx, int cy) {
 
      Brush brush = SystemBrushes.FromSystemColor(SystemColors.MenuText);
        grfx1.FillRectangle(brush, 200, 200, 100, 100);
    }
}
