Is it possible to get private GDI device context in QB64?
When working with OpenGL I need to use
HDC hDC = NULL - due to the subsequent call to the C BuildFont command (it is available in gdi32.dll, I have it declared, it works, and then I need to convert its output using the C SelectObject function to the Windows wglUseFontBitmaps function.
Analogously, it goes like this:
after all #include C calls:
HDC hDC = NULL;
.
.
.
CreateFont (-24, 0, 0, 0, FW_BOLD, FALSE, FALSE, FALSE, ANSI_CHARSET, OUT_IT_PRECIS, CLIP_DEFAULT_PRECIS, ANTIALIASED_QUALITY, FF_DONTCARE And DEFAULT_PITCH, "Courier New")
.
.
SelectObject(hDC, font%&)
.
wglUseFontBitmaps(hDC, 32, 96, base)
.
.
.
_gl statements
.
.
I found all the definitions, constants for all three C functions, but i must stop work, because i am not sure - i dont know how get hDC device content. Is it possible under H file, or with next libraries, or this is not possible in QB64?
