I need to get GDK's hWNd. I found this in headers:
void dbOverrideHWND ( HWND hWnd );
but I've no idea what to do with it. Is it possible to use winmain and set up GDK manually?

If you want to get the window handle, include windows.h and globstruct.h. The handle is then available as g_pGlob->hWnd.



However, I don't think that function does what you want it to do.

hmm... interesting - can you use that to make the DirectX device render to another window?

That's what I was assuming it did. Think of the possibilities with that! Let's say you're writing a level editor, using window's forms. You could embed the GDK in a control and use the window's API for everything else! A pretty powerful option, I would say. I'll tinker with this a bit...

Please report back - I want to know - I'd check myself but I'm (LOL) Actually working on my DarkGDK OOP Lib's GUI... turning the Button control into a hybrid button+image box+picture button combo and then on to a list box

If you could do that, how would you position the DarkGDK bit within the new window?

Get the handle of a panel.

System::Windows::Forms:anel::Handle

After a bit of testing, I've found that it reports any window other than the GDK window to be invalid. Kind of squashes that dream of integration. A quick bit of browsing revealed this:

From what I can tell, this creates the window. If this function were called at the start of the program by the programmer instead of the engine, there would be a great deal more flexibility.

I dunno - ApexNow got it to work - and I saw some post a ways back - not sure if it was abut .Net or C++ version - but some guy who wasn't using DarkGDK for games - got it to display stuff in a Windows Form as a "panel" ... I think he said something about it being setup as a picturebox or something.

Perhaps he was rendering "offscreeen" some render target, and making image from it and pasting it or something... I'm sure its possible one way or another though.

Perhaps he did, I'll have to see how. I was trying to transplant the GDK into another window, just as a proof of concept, not necessarily a form element just yet.

EDIT: I've investigated dbInitDisplay() a bit. Used in the following manner, I had some interesting results, all followed by a crash.


For this experiment dwDisplayType is the variable.

Values and results:
0 - No change
1 - Resizes as expected
2 - A message, "Display mode not supported."
3 - Program is apparently trying to run full screen. Nothing draws except the normal window, but when the window has focus all control is lost. No crash, just a halt.
4 - Window maximizes
5 and on - No change

Take what you will from this test. Perhaps it would be possible, in the future, to set up the GDK on our own, which would allow you to fully customize display options.
