Is there a possibility to generate some kind of sound or beep from within a MINGW/GRX Win32 program ? Thanks for any pointers. -- Gruss Waldemar Schultz. Technische Universität München, Zentrum Mathematik M1, D 80290 München Tel: +49 (0)89 2892 8226 FAX: +49 (0)89 2892 8228

Announce: GRX 2.4.2
by Mariano Alvarez Fernandez 21 Jun '01

21 Jun '01

Hi all: I'm pleased to announce GRX 2.4.2 Here is the changelog: 01/06/12 Modified win32 input code to work GrMouseGetEvent and GrKeyRead at the same time when GrMouseEventEnable(1,0) is set 01/06/07 Merged makedefs.gnu, makedefs.x11, makedefs.dj2 and makedefs.w32 in makedefs.grx (readme file updated) 01/06/06 Now we can use "GRXMain" for all GRX versions, grx20.h defines it like "main" except for the win32 version. Deleted the ugly "#ifdef __WIN32__ ..." in test programs (except for BGI tests) 01/06/05 Added the Linux framebuffer videodriver (vdrivers/vd_lnxfb.c) alpha stage, only in 16 or 24 bpp. To use it set GRX20DRV to "linuxfb" in the GRX Linux version. The mouse doesn't work 01/06/05 Some minimal changes to compile ok with gcc 2.96 and Linux 2.4.x 01/05/30 Applied patch to sanity bgi code for gcc 3.0, by Andris Pavenis 01/05/28 Modified makefiles for linux and x11. Now they build shared and static libs at the same time. Added install and uninstall targets. 01/05/16 Applied patch to add standard pascal makefiles for dj2, w32, x11 and lnx. pascal/bgi/test and pascal/bgi/demo merged in pascal/bgi. Pascal readme updated. By Maurice Lombardi 01/05/09 Applied patch to produce makefiles for mingw32 pascal tests by Maurice Lombardi Download: For linux/X11 users: http://www.terra.es/personal/malfer/zipfiles/grx242.tar.gz For DJGPP/Mingw users (with manifests files): http://www.terra.es/personal/malfer/zipfiles/grx242s.zip Enjoy, M.Alvarez

I will try to explain. If you don't use the mouse you can use GrKeyRead safety. If you use GrMouseGetEvent to get keyboard and mouse event, it's ok too. But if you want to get keyboard inpunt by GrKeyRead and mouse input by GrMouseGetEvent you must call GrMouseEventEnable( 0,1 ). Why? Because if not GrMouseEvent consumes the keyboard inputs and GrKeyRead works erratically. Why to use both functions at the same time?. Well, it can be to easy port a program to GRX (like my parchis game) or because the program defines a interface with separate functions (like the DEPUI gui). Mariano.

Linux framebuffer
by Mariano Alvarez Fernandez 05 Jun '01

05 Jun '01

Hi,all! I have managed to write a GRX videodriver for the Linux framebuffer (in alpha stage). Is there any body interested in testing it? Really the most difficult part was to find information about the framebuffer, I'm not was able to find any programmer's document, only the source. But when I realized how to map the framebuffer in memory, it was easy, the standard GRX framedrivers do the work.
