double buffering problem with DOS
by Jan Menzel 29 Sep '02

29 Sep '02

Hi all, could anyone please tell me, why the attached program does paint some lines on Linux X11 and nothing on Dos? I save the screen context, create a new context (as large as the screen), activate, paint and copy it to the screen with GrBitBlt. Works fine on Linux X11 but nothing happens on Dos. The new context does not get visible. (Using GRX 2.44 BCC 3.1 with memory model Large on a Win98 dos box) Thanks.

display flushing problem on Linux X11
by Jan Menzel 27 Sep '02

27 Sep '02

Hi all, if one does some drawing followed by a GrSleep() on Linux X11 the display is incomplete while sleeping. My fix: add "FSync(_XGrDisplay, 0)" before usleep() in src/misc/x11misc.c.

Re: avoiding flickering and GRX and BCC 3.1 and 5.2
by Jan Menzel 26 Sep '02

Hi Mr. Alvarez, Hi Hartmut Schirmer thank You for Your help with the flickering. I just overlocked the GrBitBlt() function for quite some time... Included You'll find my nodes on GRX with BCC 3.1 and 5.2: (I tried so send it earlier to but the mail address on the GRX web side is wrong. It ends in teleline.es, which returns with an error. Sending this mail to teleline.net returns also with an error.) Hi Mr. Alvarez, today I tried compiling grx 2.44 with Borland C++ 5.2 and 3.1 and found two problems: 1. the file vesainfo.c, which resists in src/utilprog is expected in src/vdrivers. After coping it the compilation of the library went fine for both 5.2 and 3.1. 2. while compiling circtest.c the symbol _GrSleep was not found. I did not tried to track the problem down sins I only needed the library. I just wanted to mention it. Today I found out, that _GrSleep is defined by src/misc/dosmisc.c. This file is just missing in makefile.bcc. I also think, that the vesainfo.c file problem should be fixed by updating the makefile. Thank You again.

Re: Anybody using grx under Windows XP?
by Josu Onandia 26 Sep '02

Hi Allan, I've developed a program for Windows using Grx, and I've been told that this program is running under XP without problems. The only difference with W95 is that XP is more slow, in general, and specially the bitblits.

avoiding flickering
by Jan Menzel 26 Sep '02

26 Sep '02

Hi all, how can I avoid the flickering of clearing the screen and repainting it? I tried to paint into a context but can't get it visible. (on Linux X11, with BCC 3.1 I was not able to create a context as large as the screen at all). Can anybody please give me a hint? Thanks.

Anybody using grx under Windows XP?
by Allan Kugel 26 Sep '02

26 Sep '02

Hello, all - I am trying to port some grx programs to a new windows XP system, compiling with djgpp. I'm using the version of GRX that is on the djgpp site, namely 2.4.3. The test program comes up, but things don't look right; there's a squished rose, and the demo programs kick out without any visible action. Offhand, I suspect that the graphics mode is not right. (some recompiled grx programs run with some of the expected display off the screen, and circles flattened). Before I try to spend serious time tracking this down, does anybody out there have experience running grx on windows XP? Any quick suggestions?

Request for help on the GRX X11
by Mariano Alvarez Fernandez 25 Sep '02

Hi. When you click in the close button in a window that stores a GRX program, the program is aborted. I have added code to show a message in the Windows port, but I don't know how to do it in X. Somebody has any clues? Thanks, M.Alvarez

The video driver source are in the src/vdrivers/vd_lnxfb.c In line 58: ttyfd = open( "/dev/tty",O_RDONLY ); it try to open the tty, you must check if a value other of -1 is returned. In line 95: if( mp->extinfo->frame && ttyfd > -1 ){ ioctl( ttyfd,KDSETMODE,KD_GRAPHICS ); } it try to set the tty in graphics mode and the character cursor must disapear here. Regards, M.Alvarez

I am using the new framebuffer capability. My only problem so far is I am getting my cursor on the screen. How can I cover this up, eliminate it, or move it to a lower level. Mark Felton mark.felton(a)echostar.com <mailto:mark.felton@echostar.com> 303-706-5317
