No kbstat information in win32 port?
by Stefan Giesen 12 May '02

12 May '02

Hi, I'm wondering if the win32 port of libGRX 2.4.4 doesn't support "kbstat" in _GR_mouseEvent? I need this status information for my program (I use "Ctrl-Mouseleft" and "Ctrl-Mouseright" to select something on the screen and "Alt-Mouseleft" and "Alt-Mouseright" to zoomin and zoomout). Bye, Stefan Giesen

GrResizeSubContext
by Mariano Alvarez Fernandez 02 May '02

02 May '02

Hi. The actual GrResizeSubContext implementation refers the new size to subcontext coordinates instead to the father context coordinates. In my opinion this is a bug easy to fix, but it can break existing programs. Comments?

Overlapping Window clears screen
by Eike Lange 10 Apr '02

10 Apr '02

Hi! While doing some graphic stuff with GRX 2.4.3 and GNU Pascal, the following problem encountered: * Each time, a GRX window is overlapped by another window, the GRX window clears the overlapped area and does not display the context anymore. This happens in all GR_*_width_height_graphics modes. * Sometimes, the context of the GRX window is not visible. A restart of the program solves the error. I'm using GNU/Linux, SuSE 7.3, KDE/Fvwm2. Any ideas how to fix this? Eike

grx2.4.4 mingw GRXMain MAIN__
by Gerhard Schneider 19 Mar '02

19 Mar '02

grx2.4 and mingw32 For simplicity I wrote a short program.. For compiling with fortran I have to compile it as follows: gcc -c test.c g77 -o test test.o -lgrx20 -mwindows I need g77 for linking with FORTRAN code requiring the FORTRAN libraries.. test does do nice things (no window for the graphics context..) The MAIN__ (required as PROGRAM xxx for the fortran library) and GRXMain seem to be fighting against each other.. -- test.c -- #include <grx20.h> #include <malloc.h> static int xmax, ymax, status; int MAIN__() { GRXMain(); } int GRXMain() { gstest1(); } gstest1() { long nplanes; int points[4][2] = {{30,30},{300,30},{300,300},{30,300}}; GrLineOption GSDefinition; /* Initialisiere Graphik */ GrSetMode(GR_default_graphics); xmax=GrMaxX(); ymax=GrMaxY(); /* Initialisiere eine Farbe (Rot) */ GrSetColor( 2, 255, 0, 0); /* Zeichne Viereck mit Groesse des Bildschirms -10 */ GrBox(10, 10, xmax-10, ymax-10, 2); GrSetMode(GR_default_text); } --- Any idea?

grx2.4.4 mingw GRXMain MAIN__
by Gerhard Schneider 16 Mar '02

16 Mar '02

grx2.4.4 mingw In grx20.h GRXMain is defined as main.. This is some kind of a problem if you link FORTRAN programs, which require the PROGRAM.. structure (that's MAIN__ for gcc) to the GRX libraries. There hasn't been such a problem with the old GRX2 and djgpp. Is there any planned workaround for that problem? Thank you in advance!

GRX 2.4.5 pre-release
by Mariano Alvarez Fernandez 14 Feb '02

14 Feb '02

Hi. I think it's not much interest in GRX nowadays. Anyway here is a pre-release for 2.4.5, mostly win32 related: Download it from: http://grx.gnu.de/download/grx245p1.zip MD5SUM for the package: c7d5f1027f171b713dbbda38fb8f5242 *grx245p1.zip Only the zip archive is provided, but note, the zip archive expand to grx245, not to the contrib directory. Changes: 02/02/11 The makefile install target installs the grxprint.h file if printer support is activate 02/02/11 Inprovements to the win32 driver: Now the GRX window is properly closed, so the previous app gets the focus. 02/02/02 Inprovements to the win32 driver: The w32 imput queue implemented as a circular queue. All the input related code moved to w32inp.c from vd_win32.c The main window is created in WinMain, so the grx program can use other videodrivers like the memory one. Now memtest works. Now the printer stuff compiles and run, checked with the DeskJet driver, printing to a file and them "copy file lpt1", but the printout is not totally correct (?).
