heres the source http://apache.airnet.com.au/~praisegd/miscelanious/opengldialog.zip ive searched about the forums to find the answer to my question, but alas i have not been able to find what i need. my program consists of a main window and then 3 dialog''s ColourCombo,Dialog1 and DView the DView dialog is a child of Dialog1 im using DView as my opengl window but it doesnt show, if i make the window a popup or an overlapped window it shows fine but doesnt stick to my larger window when i move it around the screen the other problem im having is that even if i choose popup or overlapped, any geometry i create doesnt show in the window, even tho it seems to be working fine,, im very new to the world of programming and would love some help on the subject please if anyone can help, i really appreciate it !!My bRaiN is FiLLEd With HappY Juice!!

i know similar questions have been asked before regarding this matter, i would really appreciate anything anyone can tell me on this matter.



!!My bRaiN is FiLLEd With HappY Juice!!

i would just have a quick guess and say that nobody actually knows how to do this,

fi im right just say so, and i will post my worked out version sometime in the future

Have you gone through Nehe''s tutorial #1 for creating an OpenGL window without any other dialogs?

If so, putting OpenGL in a child window is just that easy. In tutorial 1 you see a DC for the main window. Child windows have DCs too - just take that DC and pass it to wglCreateContext and voila, OpenGL.

I have several MFC samples on my site that do this.

Love means nothing to a tennis player

My nothing-to-write-home-about OpenGL webpage. (please pardon the popups!)

slightly off topic, but what is dview?

I do what DalTXColtsFan does. Use the Handle of different DC''s for different objects, that way I can render to Buttons, Edit boxes, Memo boxes or many other things on any form.

You should change your IDD_DVIEW dialog resource style from "POPUP" to "CHILD" and add the following line after the Dialogs creation:

Dialog = CreateDialog( hInstance,MAKEINTRESOURCE(IDD_DIALOG),hWnd,DialogProc);
DView = CreateDialog( hInstance, MAKEINTRESOURCE(IDD_DVIEW), Dialog, DViewProc);
ColourCombo = CreateDialog(hInstance,MAKEINTRESOURCE(IDD_COLOURCOMBO),hWnd,ColourComboProc);

+ SetWindowPos( DView, HWND_TOP, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

Because the static frame is hidding the DView

It''s just like rendering into a window except with this code it is rendered into one of the dialog items, the edit text box.

You will be missing a resource the icon, replace it with another.

I can e-mail you the whole project plus sourcecode if you want to actually see the end result and you can''t get it to work.

Hope that helps.

You should change your IDD_DVIEW dialog resource style from "POPUP" to "CHILD" and add the following line after the Dialogs creation:

Dialog = CreateDialog( hInstance,MAKEINTRESOURCE(IDD_DIALOG),hWnd,DialogProc);
DView = CreateDialog( hInstance, MAKEINTRESOURCE(IDD_DVIEW), Dialog, DViewProc);
ColourCombo = CreateDialog(hInstance,MAKEINTRESOURCE(IDD_COLOURCOMBO),hWnd,ColourComboProc);

+ SetWindowPos( DView, HWND_TOP, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

Because the static frame is hidding the DView

thankyou so much, i cant believe it was as simple as the static frame hiding my child window :O), your a legend danielbila thanks heaps, if you ever need some simple 3d models i will gladly try and help you

ok now all i have to get is some geometry to actually show up in the window which is never usually a problem, but for some reason its just not doing it

[edited by - TyKeiL on December 25, 2003 5:55:59 PM]

ok ive updated the source a little
http://apache.airnet.com.au/~praisegd/miscelanious/opengldialog.zip

my cube isnt showing up.!!

now i found something curious which makes me confused, i havedefines 3 GLfloat''s as ColourR ColourG ColourB and made the keyboard modify those numbers "r""g""b" and also up and down arrows to change them all. but what i have found is that my program "remembers" what the old values of those humbers were so when i change them using my combo box they work fine but when i changes them after that using the up and down keys it resets there numbers to 0 and starts from there, which isnt technically correct, oops im rambling about something mostly unimportant,

its my cube i want to show up, can anyone help me please,,

this is what im going to be putting in the glwindow when im done
