<TITLE>BUG: SetWindowName() for vtkWin32OpenGLRenderWindow</TITLE>

<P><FONT SIZE=2 FACE="Arial">If you set the window name in Windows before the the window is actually created, the name is obliterated. For example, the following code fragment produces a window with the name "Visualization Toolkit - Win32OpenGL #1":</FONT></P>

</P>
</UL>
<P><FONT SIZE=2 FACE="Arial">The problem lies in vtkWin32OpenGLRenderWindow::CreateAWindow(). Here the title of the window is set without regard to the current value of the WindowName member variable. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">To fix the problem I suggest setting the WindowName to "Visualization Toolkit - Win32OpenGL #" in the constructor. When CreateAWindow() is called, if WindowName has not been changed then append the number of this window to the WindowName as is done currently. Otherwise, leave the name as it is. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">Are there any objections to this fix or better suggestions?</FONT>
