does vizard handle input differently when it's embedded?

[Adam.Grey]

Actually I couldn't get vizard to respond to a resize. So I started searching for automatically resizing a hosted window and found a separate solution: involve winforms. Adapting this, I was able to get what I needed. Many thanks for pointing me in the right direction.
It now resizes, responds to input, etc etc. This method is reliant on the main window handle of the vizard process, so I regrettably can't support the console in my nicely encapsulated vizard control. It has to wait for vizard to start up the main form, so there's a quick flash of vizard's graphics window out of place.
So to anyone looking to embed a win32 application in a WPF control, I'd say just use winforms.
and I guess to answer my own original question, "nope."

I'm not sure this will work, but another method is to reparent the Vizard graphics window to the WPF window, instead of reusing the WPF window handle. This is what the Vizard Script -> Run Docked command does, and input messages still work properly.

Let the Vizard script create its own window as usual, but parent it to the handle passed to the command line:

viz.go()

import win32gui
import win32con

if(len(sys.argv) > 1):

    viz.window.setBorder(viz.BORDER_NONE)
    viz.window.setPosition([0,0])

    hwndChild = viz.window.getHandle()
    hwndParent = int(sys.argv[1])

    style = win32gui.GetWindowLong(hwndChild,win32con.GWL_STYLE)
    style = style | win32con.WS_CHILD
    style = style & ~(win32con.WS_OVERLAPPEDWINDOW | win32con.WS_POPUP)
    win32gui.SetWindowLong(hwndChild,win32con.GWL_STYLE,style)

    win32gui.SetParent(hwndChild ,hwndParent)

One important step with this method is that you will need to manually resize the Vizard graphics window when the parent window is resized. If you know the WPF control will always remain the same size, then you can hard code the size of the window in the Vizard script, or pass it as an argument.
