I wrote winapi application.Which during creation defined :
[code]
CreateGLWindow(hwnd,"OpenGL",800,600,16,fullscreen);
CreateWindow(TEXT("button"), TEXT("Choose Shading Mode"),
WS_CHILD | WS_VISIBLE | BS_GROUPBOX,10, 610, 300, 120, hwnd, (HMENU)
0,hInstance, NULL);
CreateWindow(TEXT("button"), TEXT("Wireframe"),
WS_CHILD | WS_VISIBLE | BS_AUTORADIOBUTTON,20, 630, 100, 30, hwnd,
(HMENU)IDC_M_WIRE , hInstance, NULL);
CreateWindow(TEXT("button"), TEXT("Flat"),
WS_CHILD | WS_VISIBLE | BS_AUTORADIOBUTTON,20, 660, 100, 30, hwnd,
(HMENU)IDC_M_FLAT , hInstance, NULL);
CreateWindow(TEXT("button"), TEXT("Smooth"),
WS_CHILD | WS_VISIBLE | BS_AUTORADIOBUTTON,20, 690, 100, 30, hwnd,
(HMENU)IDC_M_SMOOTH , hInstance,NULL);
[/code]
in CreateGLWindow it calls:
[code]
CreateWindow( wc.lpszClassName, TEXT("Graphics"),
WS_OVERLAPPEDWINDOW | WS_VISIBLE,10, 10, 800, 800, 0, 0, hInstance,
0);
[/code]

The procedure is controlled via keyboard and radio buttons defined
above
[code]
case
WM_KEYDOWN: // Is A Key Being Held Down?
{
switch LOWORD(wParam)
{
//======================
//Move forward/backward
// to Z axis
//======================
//Move forward
case VK_DOWN :
stateM->incZ();
break;
//Move backward
case VK_UP:
stateM->decZ();
break;
}
}
case
WM_COMMAND:
{
switch(LOWORD(wParam))
{
//Set WIRE Model (Edges only)
case IDC_M_WIRE:
stateM->setWire();
break;
//Set FLAT Shading Model
case IDC_M_FLAT:
stateM->setFlat();
break;
//Set SMOOTH Shading Model
case IDC_M_SMOOTH:
stateM->setSmooth();
break;
}
}
[/code]

When the application is controlled via keyboard it works properly,but
when I set one of the radio buttons - it performs the functionality it
has to perform when radio- button is checked AND when I want to
control via keyboard (after it) I can't no more control it like
before.
It seems that application doesn't react on keyboard messages
Only when I minimize and maximize application window back, the
keyboard control start to work properly.
Thank you in advance

When radio buttons have the focus they usually handle the up and down
keys to move up and down in the list of radiobuttons. (At least, they
do when hosted in a dialog. Not sure if the dialog manager does that
or if the radiobutton itself does.)

If it's that or something similar, you put something in your existing
radiobutton event/handler code so that when the radiobutton selection
changes the focus is set back to whichever component you usually want.
Of course, then you'll have non-standard radiobutton behaviour which
probably isn't a good idea.

You could also subclass the radiobuttons to make them pass VK_DOWN and
VK_UP to the parent window. That would give you slightly more normal
behaviour, but still nonstandard.

I have a 3 radio buttons(btw i have changed them with regular push
buttons and still have the same effect).So when i choose different
modes with those buttons it works OK and change it and other controls
works too except a keyboard for the main window only when I minimize
and maximize it back it returns to normal

Other button types will also do it. Try opening any standard dialog
and give the OK button the focus, then use the cursor keys. Chances
are (unless the dialog is unusual) you'll move to the Cancel button
etc.
