OK. See the *.pl and *.c files. In C I do exactly the same, but rectangle is not broken !? Sorry, I used gnome app. template for C variant (though, it shouldn't make a difference?). Many thanks in advance! Dmitry Show quoted text

#include <gnome.h> /* our main function */ int main(int argc, char *argv[]) { GnomeApp *app; /* the main window pointer */ GnomeCanvas *canvas; /* the canvas */ GtkWidget *w; gnome_init("test", "1", argc, argv); app = GNOME_APP(gnome_app_new("test", "Test")); /* create a new canvas */ w = gnome_canvas_new(); canvas = GNOME_CANVAS(w); gnome_canvas_item_new(gnome_canvas_root(canvas), gnome_canvas_rect_get_type(), "x1", 90.0, "y1", 40.0, "x2", 33000.0, "y2", 100.0, "fill_color", "mediumseagreen", "outline_color", "black", "width_units", 4.0, NULL); /* set where can the canvas scroll (our usable area) */ gnome_canvas_set_scroll_region(canvas, 0.0, 0.0, 60000.0, 6000.0); /* set the contents of the app window to the canvas */ gnome_app_set_contents(GNOME_APP(app), w); gtk_widget_show_all(GTK_WIDGET(app)); gtk_main(); return 0; }

Oops. In your environment C test shows the problem also!? See my screenshot of huge_rect.c. Show quoted text
Gnome2/Canvas.so is linked against libgnomecanvas library: $ ldd Canvas.so linux-gate.so.1 => (0x00ae3000) libgnomecanvas-2.so.0 => /usr/lib/libgnomecanvas-2.so.0 (0x00747000) . . . $ rpm -qf /usr/lib/libgnomecanvas-2.so.0 libgnomecanvas-2.10.0-1 (I've restored the original RPM libgnomecanvas-2.10.0-1 from RH, but it didn't solve the problem.) But C program appears to be not linked to the libgnomecanvas at all!? May be dynamic loading is used at runtime (I'm not familiar with Gnome internals...). See the ldd output: $ ldd huge_rect linux-gate.so.1 => (0x008b1000) libgnomeui.so.32 => /usr/lib/libgnomeui.so.32 (0x00c77000) libart_lgpl.so.2 => /usr/lib/libart_lgpl.so.2 (0x00895000) libgdk_imlib.so.1 => /usr/lib/libgdk_imlib.so.1 (0x00137000) libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x00bd7000) libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x00bbb000) libgtk-1.2.so.0 => /usr/lib/libgtk-1.2.so.0 (0x02fd8000) libgdk-1.2.so.0 => /usr/lib/libgdk-1.2.so.0 (0x02f83000) libgmodule-1.2.so.0 => /usr/lib/libgmodule-1.2.so.0 (0x00db9000) libdl.so.2 => /lib/libdl.so.2 (0x00a7e000) libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x00101000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x00baa000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00ad4000) libgnome.so.32 => /usr/lib/libgnome.so.32 (0x00824000) libgnomesupport.so.0 => /usr/lib/libgnomesupport.so.0 (0x0081c000) libesd.so.0 => /usr/lib/libesd.so.0 (0x03906000) libasound.so.2 => /lib/libasound.so.2 (0x02a59000) libaudiofile.so.0 => /usr/lib/libaudiofile.so.0 (0x02e22000) libm.so.6 => /lib/libm.so.6 (0x00a84000) libglib-1.2.so.0 => /usr/lib/libglib-1.2.so.0 (0x03132000) libc.so.6 => /lib/libc.so.6 (0x00953000) libdb.so.2 => /usr/lib/libdb.so.2 (0x0080b000) libz.so.1 => /usr/lib/libz.so.1 (0x00aab000) /lib/ld-linux.so.2 (0x00119000) libpthread.so.0 => /lib/libpthread.so.0 (0x00ac0000) I send you my binary huge_rect, may be it's runnable on your system (though, you may not run it if you're afraid of consequences)? Howevere, the problem is obviously on C level, but I still can't reproduce it in *.c test... What could you advice me for submitting the bug to developer.gnome.org ? Should I try to build a fresh TAR Gtk/Glib/Gnome/GnomeCanvas installation and make a test for the latest libs from gnome.org? I develope a sci. application for RedHat RHEL4 platform, therefore I have to use the most compatible Fedora Core version (which is FC4). And I already had some problems with RedHat libgnomecanvas-2.10.0-1 (it crashed on destroy stage). That's why I switched to libgnomecanvas-2.14 (which I have to install on customers' system manually which upsets their administrator). So, I would be happy to have a fixing patch for the libgnomecanvas-2.14 SRPM. Thank you very much. Regards, Dmitry Show quoted text
