Q179852 HOWTO: Enabling Hot-Tracking in an AFC UIPushButton

The information in this article applies to:

SUMMARY

The Microsoft Application Foundation Classes (AFC) includes the ability to enable hot-tracking by overriding the setHot method.

MORE INFORMATION

The sample code below demonstrates overriding the setHot(boolean hot) method, changing the color of the component inside a UIPushButton when the cursor is over the button.

Sample Code

import com.ms.ui.*;
   import com.ms.fx.*;
public class HotTrackDemo {
     public static void main(String args[])
     {
       UIFrame frame = new UIFrame("HotPushButton Example");
       frame.setLayout(new UIGridLayout(3,0));
       frame.setSize(320,200);
       frame.setVisible(true);
       HotPushButton btn1=new HotPushButton("BUTTON1");
       HotPushButton btn2=new HotPushButton("BUTTON2");
       btn2.setColors(FxColor.green,FxColor.lightGray);
       frame.add(btn1);
       frame.add(btn2);
     }
   }
class HotPushButton extends UIPushButton {
     java.awt.Color colorNorm=java.awt.Color.black;
     java.awt.Color colorHot=java.awt.Color.red;
     public HotPushButton(String value) {
       super(value);
     }
     public HotPushButton(IUIComponent comp) {
       super(comp);
     }
     public void setColors(java.awt.Color hot,java.awt.Color norm) {
       colorHot=hot;
       colorNorm=norm;
       setHot(isHot());
     }
     public void setHot(boolean hot) {
       super.setHot(hot);
       setForeground(hot?colorHot:colorNorm);  // Change color of component
       invalidateAll();
     }
   }
