Koch | Hello together,
a short question about opengl and xpse: there a Possibility, a ogl("xyz",...) commands in a nproc incorporate?
Konkret goes it around the commands oGL("TestMouse", X, Y, Z), or @oGL("TestXY", X, Y, Z, SX, SY).
The Testmodus of opengl not working always so dolle what about me try on the lane, it To bypass.
lovely Greeting

No, integrally Specifically this goes unfortunately not yet -
it was me in first Tests not been successful, from the Assembler-DLL out on whom
XProfan-OGL-Context anzubinden and faith, that OGL there something against it has.
i know but not very Why the lying but in my first Tests with reinem
nativen Profan, that without The Runtime auskommt, can too OpenGL nativ
benefit. These Special XPSE-Version is not yet public.
what I do not tested having was whom whole OGL-Context a nProc out
To produce, this could imho functions. |

Koch | first once thanks for response. Sorry, I have the Topic now 2time tuned. (I had not More found.)
next question: understand I your last distribution correctly., I The Api-command, for the ogl-commands standing, try can To benefit?
if so, where find I because The API-command for oGL("TestMouse", X, Y, Z), or @oGL("TestXY", X, Y, Z, SX, SY))? |

RGH | for the OpenGL-Api there numerous (mostly english) Documentations in the network, too directly with Microsoft. (Date helps.)
many the XProfan-OpenGL-functions vereinen but several API-Aufrufe, partly too with komplexer Logik, around the Open-GL-Programming To vereinfachen.If one in XProfan z.B. a die with a appeal Done, custom it in nativer API a whole row of Call.

Koch | my first attempt was too, a OpenGL-API Substitute for the two obigen functions to find, what not so integrally successful was.
therefore vermutete so did i, that a whole row of command behind it stick, The in XProfan to a function zusammengefügt get. around the Api-command take after and directly utilize to, should I but know, as hot. therefore my question, what behind oGL("TestMouse", X, Y, Z), or @oGL("TestXY", X, Y, Z, SX, SY)) stick.
PS: wiki.delphigl.com has me yet with opengl always weitergebracht. |

some Notes:
LesePara list whom next Parameter the Programmzeile. the Result becomes in both functions in RPar.Lng (Long-Integer) zurückgeliefert.Error 400 besagt, that OGL not initialized watts and it accordingly no OGL-Window gives.

Jojo, no Streß.

Koch | another kurzer Nachtrag,
on the Page of Uwe Pascal Niemeyer [...] there a zipper-File (opengl2004.zipper), where itself a great many Examples to Programming with opengl find. so far I the survey can, becomes thereby on ogl("xyz",...) command gänzlich waived. I suspect, The Codes come from of/ one Time before openGl in XProfan eingebunden was. tappt im dunkeln functions but yet tadellos. there was too an example thereby, the The Original-Delphi Codes of RGH in the integral abbildet. all, The with opengl to do having, can I these Examples only recommend.
lovely Greeting
