Forms in DirectX

**Gadget** · 18-05-2003, 11:29 AM

How can I get forms working in DirectX? Do I need to create my own TDXForm? Can anyone give me any pointers on solutions to this problem? How do you do it?

Thanks

I'm probably stupid but what exactly do you want? Do you want to use DirectX to draw on your form (then it should be something like myDirectDraw.SetCooperativeLevel(MyForm.Handle, DDSCL_FULLSCREEN or DDSCL_EXCLUSIVE or DDSCL_ALLOWREBOOT)) or do you want to have a form pop up at runtime? Then this link may be useful (FullscreenDialog I think).

I guess it's the same thing with Direct3D.

Thanks for that link, it may help me to work out what I need. Basically I want to show TForms inside my DX application. It's fullscreen so I guess that TForm wont get drawn.

Hi, thanks for replying!

DX7

In DirectDraw7/Direct3D7:

[pascal][background=#FFFFFF][normal=#000000][number=#0000FF][string=#0000FF][comment=#248F24][reserved=#000000](1) at init time:
if (ddObject.CreateClipper(0, @ddClipper, NULL) = DD_OK) then
ddClipper.SetHWnd(0, hwndAppWindow);
ddObject.FlipToGDISurface;

(2) later
ddFrontBuffer.SetClipper(ddClipper);
ddFrontBuffer.Blt(NULL, ddBackBuffer, NULL, DDBLT_WAIT, NULL);
// or Flip
ddObject.FlipToGDISurface;[/pascal]

Thanks for the quick reply again, but I am using fullscreen mode!

You mean you need this?
[pascal]surface.Flip();
DDraw.FlipToGDISurface;[/pascal]

Thanks, but what I really wanted was some miracle way of getting forms to paint to DirectX surfaces! I think without a lot of coding it isn't going to happen. I played around with FlipToGDISurface already, it's very very slow to the point it may as well not be used.
