POUndecorated JInternalFrame becomes decorated when viewed through Remote Desktop Sharing
text
Body
copied!<p>I’m facing a problem with <code>JInternalFrame</code> implementation. I have made the <code>JInternalFrame</code> undecorated, so that the title bar and border of the <code>JInternalFrame</code> gets removed. The problem occurs in the following scenario.</p> <ol> <li><p>Execute the program in a Windows 7 machine.</p> <ul> <li>At this point the <code>JInternalFrame</code> remains undecorated.</li> </ul></li> <li><p>Access the Windows 7 machine using remote desktop sharing from another machine.</p> <ul> <li>Now the title bar and border of the internal frame becomes visible.</li> </ul></li> </ol> <p>This issue occurs only in Windows 7 machine, and not in Windows XP. You can access the Windows 7 machine using remote desktop sharing from another Windows 7 machine or Windows XP machine.</p> <p>Also if you access the machine using remote desktop sharing first, and then execute the program, the <code>JInternalFrame</code> remains undecorated.</p> <p>Steps to reproduce</p> <p>Step 1: Execute the application in a Windows 7 machine.</p> <p>Step 2: Access the Windows 7 machine using remote desktop sharing from another Windows 7 or Windows XP machine.</p> <p>Step 3: Check the GUI of the application</p> <p>Result :- The title bar and border of the undecorated <code>JInternalFrame</code> becomes visible.</p> <p>If anyone has faced this issue or if anyone has a solution for this issue, kindly share your thoughts.</p> <p>A sample code using which you can reproduce this issue is given below.</p> <pre><code>/* * Copyright (c) 1995, 2008, Oracle and/or its affiliates.
