  • Microsoft Visual J++ 6.0

STATUS

MORE INFORMATION

Steps to Reproduce Behavior

  1. In Visual J++ 6.0, create a new Windows Application project.
  2. Add a paint event handler by opening the Properties window, double-clicking the form to display the display the form's properties in the Properties window, opening the event list, and double-clicking the paint entry.
  3. Add System.out.println(e.clipRect); to the new method.
  4. Debug the application.
  5. Cover only the lower-right corner of the form with another window, such as Notepad.
  6. Click on the form to bring it to the front.


RESULT: The output for a form that is 300 pixels wide and 275 pixels high should be like the following:
{x=202,y=153,width=300,height=275}
If the entire client area of the same form is repainted, you should see the following:
{x=0,y=0,width=300,height=275}
