Hi all,<br><br>I just installed Qt 4.2.1 along side my 4.1.4 version and ran a very simple <br>program. I am using VTK along with Qt and this worked without any problems <br>before.<br><br>However, when I run the program now, I get the following error:
<br><br>X Error: BadWindow (invalid Window parameter) 3<br> Major opcode: 3 (X_GetWindowAttributes)<br> Resource id: 0x0<br>X Error: BadValue (integer parameter out of range for operation) 2<br> Major opcode: 1 (X_CreateWindow)
<br> Resource id: 0x0<br>X Error: BadWindow (invalid Window parameter) 3<br> Major opcode: 20 (X_GetProperty)<br> Resource id: 0x0<br>X Error: BadWindow (invalid Window parameter) 3<br> Major opcode: 3 (X_GetWindowAttributes)
<br> Resource id: 0x3c00002<br>Segmentation fault<br><br>This happens when I call the QVTKWidget SetRenderWindow method. Has anything <br>substantial changed that could cause this error?<br><br>Anyone else here using Qt
4.2.1 successfully with VTK?<br clear="all"> <br>Cheers,<br><br>Anja
