[opendx-dev] Ideas for X independency

[David Thompson]

Jeff and I have been looking at the DX internals lately due to a 
project we're considering and was wondering if anyone might have a 
unique solution. Currently, DX shares a named X-Window between the 
executive and other processes such as the VPE to perform visual 
displays. It's quite unique and I can't see a solution for a Windows 
equivalent. For example, the VPE creates an Image Window (X-Window 
internally) and then passes this X-Window's name via communication to 
the executive. The exec can then set procs as well as use this window 
as its own thus having two applications manipulate the same window. 
Within Win32, it is possible to share a common window via a handle, 
but you don't have this same advanced functionality of being able to 
assign the window's events to two different programs. So if I were to 
try and design a Windows native version of DX, how might this 
functionality be handled--remember, this graphic window can also be 
OpenGL based. We've thought of making the executive an ActiveX 
control but not totally sold on this idea. Any suggestions welcome.
