 Posted: Fri Apr 01, 2005 4:36 pm Post subject: Window Procedure |
|
Ieprieksh atvainojos par garu pustu, bet man jau saap galva no kluudas mekleeshanas...
Taa, kas par probleemu? Probleema ir taada, ka savu window procedure(kuras deelj neveras ciet device context un HWND) apmainot ar gandriiz taadu pashu no http://www.gametutorials.com/ wiss iet kaa smeereets. 
Te buus mana: | Code: | LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam){
switch(uMsg){
case WM_ACTIVATE:
if(!HIWORD(lParam))
active = true;
else
active = false;
break;
case WM_SYSCOMMAND:
switch(wParam){
case SC_SCREENSAVE:
case SC_MONITORPOWER:
return 0;
}
break;
case WM_CLOSE:
PostQuitMessage(0);
break;
case WM_KEYDOWN:
keys[wParam] = true;
break;
case WM_KEYUP:
keys[wParam] = false;
break;
case WM_SIZE:
// LOWORD = width, HIWORD = height
ResizeScene(LOWORD(lParam),HIWORD(lParam));
break;
}
return DefWindowProc(hWnd,uMsg,wParam,lParam);
} |
un te buus taa, kas straadaa | Code: | LRESULT CALLBACK WndProc( HWND hWnd, // Handle For This Window
UINT uMsg, // Message For This Window
WPARAM wParam, // Additional Message Information
LPARAM lParam) // Additional Message Information
{
switch (uMsg) // Check For Windows Messages
{
case WM_ACTIVATE: // Watch For Window Activate Message
{
if (!HIWORD(wParam)) // Check Minimization State
{
active=TRUE; // Program Is Active
}
else
{
active=FALSE; // Program Is No Longer Active
}
return 0; // Return To The Message Loop
}
case WM_SYSCOMMAND: // Intercept System Commands
{
switch (wParam) // Check System Calls
{
case SC_SCREENSAVE: // Screensaver Trying To Start?
case SC_MONITORPOWER: // Monitor Trying To Enter Powersave?
return 0; // Prevent From Happening
}
break; // Exit
}
case WM_CLOSE: // Did We Receive A Close Message?
{
PostQuitMessage(0); // Send A Quit Message
return 0; // Jump Back
}
case WM_KEYDOWN: // Is A Key Being Held Down?
{
keys[wParam] = TRUE; // If So, Mark It As TRUE
return 0; // Jump Back
}
case WM_KEYUP: // Has A Key Been Released?
{
keys[wParam] = FALSE; // If So, Mark It As FALSE
return 0; // Jump Back
}
case WM_SIZE: // Resize The OpenGL Window
{
ReSizeGLScene(LOWORD(lParam),HIWORD(lParam)); // LoWord=Width, HiWord=Height
return 0; // Jump Back
}
}
// Pass All Unhandled Messages To DefWindowProc
return DefWindowProc(hWnd,uMsg,wParam,lParam);
}

Droshi vien taapeec ka pimajaa gadiijumaa DefWindowProc tiek izsaukta visos gadiijumos. Varbuut laabak to likt pie "default:" label switchaa.
BTW silts ieteikums no manas puses (kuru protams var atljauties ignoreet) - nesaakt maaciities speelju programmeeshanu no WinAPI - peec personiigaas pieredzes. Ir daudz vienkaarshaakas un elegantaakas lietas. Tas, ka tu lieto OpenGL, nav noteicoshais - var izmantot kaadu no daudzajiem "wrapperiem" ap WinAPI (piem. GLUT, SDL - ceru ka sheit nekljuudos). |

Ciks sapratu tev logs neverās ciet?
Ja tā, tad pēc PostQuitMessage(0); pieliec return 0;
Ja tu to neizdari, tad tiek izsaukta default message procedūra, kas ignorē tavus uzstādījumus zem WM_CLOSE;
Laikam to pašu arī bija domājis Digital-X
