I want to make the display support SDL so we can play a lot of games and make app based on SDL2.
PS: I love DOS games 🙂
SDL2 supports directFB which is not maintained anymore.
So I am consider to write a video driver for my display.
In SDL source code, SDL_DirectFB_video.c, we can get every interface:
/* Set the function pointers */
device->VideoInit = DirectFB_VideoInit;
device->VideoQuit = DirectFB_VideoQuit;
device->GetDisplayModes = DirectFB_GetDisplayModes;
device->SetDisplayMode = DirectFB_SetDisplayMode;
device->PumpEvents = DirectFB_PumpEventsWindow;
device->CreateSDLWindow = DirectFB_CreateWindow;
device->CreateSDLWindowFrom = DirectFB_CreateWindowFrom;
device->SetWindowTitle = DirectFB_SetWindowTitle;
device->SetWindowIcon = DirectFB_SetWindowIcon;
device->SetWindowPosition = DirectFB_SetWindowPosition;
device->SetWindowSize = DirectFB_SetWindowSize;
device->SetWindowOpacity = DirectFB_SetWindowOpacity;
device->ShowWindow = DirectFB_ShowWindow;
device->HideWindow = DirectFB_HideWindow;
device->RaiseWindow = DirectFB_RaiseWindow;
device->MaximizeWindow = DirectFB_MaximizeWindow;
device->MinimizeWindow = DirectFB_MinimizeWindow;
device->RestoreWindow = DirectFB_RestoreWindow;
device->SetWindowGrab = DirectFB_SetWindowGrab;
device->DestroyWindow = DirectFB_DestroyWindow;
device->GetWindowWMInfo = DirectFB_GetWindowWMInfo;
/* !!! FIXME: implement SetWindowBordered */
#if SDL_DIRECTFB_OPENGL
device->GL_LoadLibrary = DirectFB_GL_LoadLibrary;
device->GL_GetProcAddress = DirectFB_GL_GetProcAddress;
device->GL_MakeCurrent = DirectFB_GL_MakeCurrent;
device->GL_CreateContext = DirectFB_GL_CreateContext;
device->GL_SetSwapInterval = DirectFB_GL_SetSwapInterval;
device->GL_GetSwapInterval = DirectFB_GL_GetSwapInterval;
device->GL_SwapWindow = DirectFB_GL_SwapWindow;
device->GL_DeleteContext = DirectFB_GL_DeleteContext;
#endif
/* Shaped window support */
device->shape_driver.CreateShaper = DirectFB_CreateShaper;
device->shape_driver.SetWindowShape = DirectFB_SetWindowShape;
device->shape_driver.ResizeWindowShape = DirectFB_ResizeWindowShape;
device->free = DirectFB_DeleteDevice;
Of course, I do not think VoCore2 can run OpenGL, because it do not have any video hardware, ignore that.
PS: mesa3d has a software mode but it must be very slow. 🙂
To be simple, we do not need shaped window support either…
OK, rest interfaces for windows look like necessary, every video driver has them.
So they are VideoInit/Quit, Get/SetDisplayModes, CreateSDLWindow/From, SetWindowTitle/Icon/Position/Size, Show/Hide/Raise/Maximize/Minimize/Restore/DestroyWindow.
But it still need to code a lot…
I find most of the interfaces are empty in its psp video driver, maybe there is a way to make everything simple.
Any good idea?
