Re: stop on Gtk-WARNING
there is an argument you can pass in to the application at invocation that does this. i think it is --g-fatal-warnings (eg ./foo --g-fatal-warnings). -tim ** http://mail.gnome.org/archives/gtk-devel-list/1998-August/msg00088.htmlBoncek, John wrote: http://mail.gnome.org/archives/gtk-devel-list/1998-August/msg00088.html The same for GLib-GObject-WARNINGs and other similar ones. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Boncek, John Sent: Monday, October 17, 2005 11:33 AM To: gtk-app-devel-list@gnome.org Subject: stop on Gtk-WARNING When a GTK app gets Gtk-WARNINGs without actually stopping, it can be hard to determine exactly where they're coming from.

enter_notify_event and leave_notify_event signals
hi everyone, i would like to receive the enter notfy event and leave notify event signals even when the mouse is moved into/out of a widget while a mouse button is down. anecdotal evidence shows me that only when the mouse button is released do i get these signals, beyond the leave notify event in the widget i pressed the mouse button down in. i suspect this has something to do with the drag/drop signals (which i have no experience with), as the GdkEventCrossing pointer supplied by these signals has its mode set to GDK_CROSSING_GRAB when i leave the first widget, and GDK_CROSSING_UNGRAB when i release the mouse button. does anyone know of a way i can get the enter and leave event signals regardless of any mouse buttons currently down? thanks! -tim ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
warning - bug in solaris x86 ldd breaks install of gtk+-2.4.10
i'm writing this to warn the other three users of solaris x86 in the world. :) for solaris 8 and 9, on x86 (maybe other versions as well), the sun ldd chokes on some library names, including, for example, libgtk-x11-2.0.so.0.400.10. this manifests in at least two ways: 1. when you run ldd against the library, the first line printed out has garbage (or sometimes it just crashes) for the library name. eg usira:/home/troll/timf/src/gnome/2.4/build/gtk+-2.4.10/gtk/.libs $ ldd libgtk-x11-2.0.so.0.400.10 รน = (file not found) libgdk_pixbuf-2.0.so.0 = /opt/app/gnome-2.4//lib/libgdk_pixbuf-2.0.so.0 libgdk-x11-2.0.so.0 = /opt/app/gnome-2.4//lib/libgdk-x11-2.0.so.0 libX11.so.4 = /usr/openwin/lib/libX11.so.4 libsocket.so.1 =/usr/lib/libsocket.so.1 libnsl.so.1 = /usr/lib/libnsl.so.1 libpangoxft-1.0.so.0 = /opt/app/gnome-2.4//lib/libpangoxft-1.0.so.0 libpangox-1.0.so.0 =/opt/app/gnome-2.4//lib/libpangox-1.0.so.0 libpango-1.0.so.0 = /opt/app/gnome-2.4//lib/libpango-1.0.so.0 libatk-1.0.so.0 = /opt/app/gnome-2.4//lib/libatk-1.0.so.0 libgobject-2.0.so.0 = /opt/app/gnome-2.4//lib/libgobject-2.0.so.0 libgmodule-2.0.so.0 = /opt/app/gnome-2.4//lib/libgmodule-2.0.so.0 libdl.so.1 =/usr/lib/libdl.so.1 libglib-2.0.so.0 = /opt/app/gnome-2.4//lib/libglib-2.0.so.0 libiconv.so.2 = /opt/app/lib/libiconv.so.2 libm.so.1 = /usr/lib/libm.so.1 libc.so.1 = /usr/lib/libc.so.1 libgcc_s.so.1 = /opt/lang/gcc-3.3.2/lib/libgcc_s.so.1 libXext.so.0 = /usr/openwin/lib/libXext.so.0 libXft.so.2 = /opt/app/gnome-2.4//lib/libXft.so.2 libfreetype.so.6 = /opt/app/lib/libfreetype.so.6 libz.so.1 = /usr/lib/libz.so.1 libfontconfig.so.1 = /opt/app/fontconfig-2.2.0/lib/libfontconfig.so.1 libXcursor.so.1 = /opt/app/gnome-2.4//lib/libXcursor.so.1 libXrender.so.1 = /opt/app/gnome-2.4//lib/libXrender.so.1 libmp.so.2 =/usr/lib/libmp.so.2 libpangoft2-1.0.so.0 = /opt/app/gnome-2.4//lib/libpangoft2-1.0.so.0 libdga.so.1 = /usr/openwin/lib/libdga.so.1 libexpat.so.0 = /opt/app/expat-1.95.7/lib/libexpat.so.0 2. when you run applications which link against the shared object in question, they crash.

Re: jpeg-6b
look at the generated file 'config.log'. i suspect you need to add a directory to either your include directories or library directories to pick up jpeg's headers and/or libraries. ./configure will listen to the environmental variables CFLAGS, CPPFLAGS and LDFLAGS, so you can set directives in these. for example, lets say the jpeg library is installed in /opt (/opt/include for the headers, /opt/lib for the libraries), and you are on a linux box; export CFLAGS=-I/opt/include export CPPFLAGS=$CFLAGS export LDFLAGS=-L/opt/lib -tim Jerry Pringle wrote: Hello All, Further to my earlier question (regarding Pango). I have compiled and installed Pango, but now when running configure for GTK+ I get the following error: checking for jpeg_destroy_decompress in -ljpeg... no configure: WARNING: *** JPEG loader will not be built (JPEG library not found) *** configure: error: *** Checks for JPEG loader failed. You can build without it by passing *** --without-libjpeg to configure but some programs using GTK+ may *** not work properly I have tried running make clean and the rerunning configure and make for the jpeg-6b library (downloaded from GTK ftp site), but still get the same error.

Re: want to add number to label
gtk_label_new expects a pointer to a character array (char *), but simply telling the compiler that nr is a pointer to a character array by casting it to char * does not make it a valid array. (i could tell you i was a flounder, but trust me, its still not true). you need to convert nr to a character representation of nr's floating point value. one way to do this is by using sprintf. do a 'man sprintf', but it will look something like: char buf[20]; sprintf(buf, %f, nr); -tim edward hage wrote: Hello, I think I have a simple problem but I cannot figure out how to get a float on a label. It is designed for a string, like this is a button but I want to show a float value. So my question is how can I turn a float into a suitable format to stick to a label? Example that does not work: GtkWidget *button; float nr; nr = 3.123; button = gtk_label_new ((char *) nr); Thank you, Edward ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
TreeView performance
hello all, i am writing a trading application that displays updates to financial contracts in real time, using a TreeView widget. there can be four to five hundred updates coming in a second, and under this load my application takes about 60% of the cpu time of my dual processor 2.53 mhz box. through experimentation, i noticed that when i commented out the code which updates text in its various columns (but all the other processing, and rendering of colors still occurs), my cpu usage falls to 2%. this leads me to believe that the TreeView widget just wasn't intended to be used for this sort of purpose. i'm just writing in the hopes that maybe there's something easy i could do which would lose me about 55% of the cpu usage. :) this is not a criticism of the widget at all, i think its really flexible, and once the learning curve has been climbed, convienent to use (which is why i want to do so :) ). any comments are greatly appreciated. i'm posting to both the gtk and gtkmm list, because i'm using gtkmm, but am not sure if the processing overhead is being incurred in the template instantiations of my columns or the the core tree_view widget. thanks! -tim ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
glib event loop thrashing on solaris x86?
hi! this is a somewhat vague question, which i apologize for. i'm just trying for suggestions of where i should look to find my glitch: i am running on a dual processor x86 solaris 8 box, and my gtkmm application seems to spend a lot of time thrashing in the glib event loop. truss reveals lots of this: ioctl(4, FIONREAD, 0x0804657C)= 0 gettimeofday(0x08046584)= 0 poll(0x0832D400, 2, 0)= 0 gettimeofday(0x080465A4)= 0 ioctl(4, FIONREAD, 0x0804657C)= 0 gettimeofday(0x08046584)= 0 poll(0x0832D400, 2, 0)= 0 gettimeofday(0x080465A4)= 0 top reports my cpu usage at around 60%, which seems very high for the amount of processing that is going on. has anyone run into a similar situation? if so, can you suggest things i might be doing wrong? thanks! -tim ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
