Vista - wpf and directx

Can WPFand DirectX be combined or does that question even make sense?
I am wanting make 2d games that use wpf but have the power of
directdraw.
thanks

WPF uses DirectX to draw the graphics on the screen, not GDI. So when
you program WPF, you actually program against DirectX. That said, WPF is
often described as too high level for games.

Is it possible to have a DirectXCanvas (a bit like the WindowsFormHost) or
something similar in a WPF app?

Please don't top post. It cuts the whole text under your signature when
I reply to you, and I hate to copy-paste :-)

I never heard of a DirectXCanvas or something similar. That said, I am
far from omniscient, especially not in WPF :-) Maybe you'll find
something online allowing you to have more control over the DirectX drivers.

You can add a HWND to your WPF application (WindowsFormHost is one of
the possible implementations, but you can also implement something for
other type of GDI apps). That said, that is GDI and not DirectX so
probably not what you're looking for.

Sorry I can't be more helpful,
Laurent

Well, no worries, it's just something I think I might use in some distant
future if I start to seriously look into my idea #37....

What is the game scenario you are looking at? That might be a better
way to assess options.


WPF can be indeed be used in interop with DirectX and other Hwnd
oriented technologies. I would recommend becoming acquainted with the
WPF notion of airspace and window regions:

A sample using WPF slider based databinding to a directX region is
available here:

I was thinking to make a "world designer" for my pet RPG (one day,
eventually...)
I though thatof having standart "business interface" in WPF (with list box
and such), but one othe window could present various graphic designer
surface, such as a "World Designer" / "Dungeon Designer" where you would
have a DirectX representation of whatever is designed.

Yeah, I though that HwndHost might be good enough for my purpose.

hey, thanks for the link, nice!


Other than that, on my DirectX surface I will probably want to have
tools/control or maybe a simple transparent property viewer (to look at a
creature/structure statistics for instance).

Would be nice to write it in WPF on the the view, ha, well, I guess that's
already not too bad... :-D

reading the post, making a picture of my WPF control which I will render in
the foreground is a good idea....
