BUG: Text Components Are Not Brighter for Editable Controls

• SDK for Java, versions 2.0, 2.01
• Microsoft Win32 Virtual Machine for Java
• Microsoft Internet Explorer versions 4.0, 4.01 for Windows 95
• Microsoft Internet Explorer versions 4.0, 4.01 for Windows NT 4.0

SYMPTOMS

The java.awt.TextArea and java.awt.TextField controls do not use a brighter color when they can be edited.

CAUSE

In builds of the Virtual Machine for Java prior to 2252 a brighter color was used to represent an editable control.

RESOLUTION

See the sample code below for a potential workaround.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The sample code below illustrates the problem and a potential way to workaround the problem by calling brighter():

   import com.ms.ui.*;
   import java.awt.*;

   class test {
     public static void main(String args[])
     {
     java.awt.Color c = new java.awt.Color(255,40,168);

     Frame f = new Frame("AWT Frame");
     f.setSize(320,200);
     f.setLayout(new GridLayout(3,0));

     TextArea edit1=new TextArea("Read Only");
     TextArea edit2=new TextArea("Editable (Should match brighter color)");
     TextArea edit3=new TextArea("Brighter");

     edit1.setBackground(c);
     edit1.setEditable(false);

     edit2.setBackground(c);
     edit2.setEditable(true);

     // workaround:  set background to brighter color.
     edit3.setBackground(c.brighter());
     edit3.setEditable(true);

     f.add(edit1);
     f.add(edit2);
     f.add(edit3);
     f.setVisible(true);
     }
   }
