pkd-config issue
Hi, newbie here, trying to install GTK on a pentium4, i686, with RH9 OS on it. I finally got glib to configure, make, check and install, then when I tried to install atk, I got an error when it queried for glib. It couldn't find it. So, after reading up on pkg-config (after looking at the config shell), I noticed that I could set the env variable PKG_CONFIG_PATH for .pc files I'd installed. So, I looked through the config shell some more and found the default PREFIX setting '/usr/local.' Under that, in lib/pkgconfig I could see the glib-2.0 I had just installed. Great! I setenv PKG_CONFIG_PATH /usr/local/lib/pkgconfig (there wasn't such an env var before), and voila! the shell fails again telling me that it found an older version of glib (which I have never installed). I'm installing version 2.2.2 of glib, and it's erroring out by finding 2.2.1 of glib. I've looked through the pkg-config man page, but there doesn't seem to be anything that tells me how to local and remove a specific package, like in this case, the supposed older version of glib-2.2.1. Does this sound familiar to anyone? I'm up against a wall here at the moment. Thanks. - Jimbo ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Configure glib to be installed in the same place as the old one with ./configure --prefix=/usr, make make uninstall make install. Before running configure, make uninstall everything you just installed in /usr/local. (Note: you have to reconfigure, running make prefix=/usr install gives strange problems.) ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
Gth-test demo problems
I have successfully installed GTK for the linux framebuffer but come across the following error when I try to execute the gtk-demo program distributed with the GTk+-2.4.4 distribution. Gdk_WARNING **: gdk_window_set_keep() not implemented Does anyone know how I can resolve this problem? Is it because I am using the VESA framebuffer?

Need Help Understanding a Compile Error
I need help in understanding a problem I'm encountering when compiling a particular GTK program. When compiling, at link time I get the following errors: /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_map_cache_clear' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_map_get_type' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_map_create_context' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_map_shutdown' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_get_type' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_lock_face' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_has_char' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_get_glyph' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_get_unknown_glyph' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_get_raw_extents' /usr/local/lib/libpangoxft-1.0.so: undefined reference to `pango_fc_font_unlock_face' In this case /usr/local/lib/libpangoxft-1.0.so is linked to /usr/local/lib/libpangoxft-1.0.so.0.501.0. If I change libpangoxft-1.0.so to be linked to /usr/local/lib/libpangoxft-1.0.so.0.200.5 the program compiles correctly.

OK. Here's the code modified to do what I suppose you want.

I fixed that as well. Though all this is right in the tutorial. I think
you need to RTFM + perhaps some example code and then try a bit harder.

Re: GTK Signal Definitions
configure-event partially works. Basically, I am trying to maintain the width of a pane in a GtkHPaned after the user resizes or maximizes the window.
When I stretch the edges in 90 degree angles (stretch the right edge right, top edge up, etc..) it works fine. However, when I stretch diagonally or maximize, it does not work. In my callback for configure-event I tried to returning TRUE to stifle the signal propagation. As expected, my pane was being correctly sized, but not propagating the signal had adverse effects elsewhere--as you can imagine. Below is my implementation.
g_signal_connect(dialog,configure-event,
G_CALLBACK(resize_setup_menu),(gpointer)hpane);
g_signal_connect(dialog,window-state-event,
G_CALLBACK(resize_setup_menu),(gpointer)hpane);
gboolean resize_setup_menu(GtkWidget *widget,
GdkEventConfigure *event,gpointer anything)
{
gtk_paned_set_position(GTK_PANED(anything),128);
}

You need configure_event. In my experience it's rare to want to
listen to this signal, usually it's simpler to subclass one of the
existing widgets and have a configure_event method.
As an aside, is there a list of signal definitions? The GTK API
documentation seems pretty hit-and-miss. As an example,
GtkButton explains activate but GtkWindow has nothing to
describe the signal frame-event.
I think frame_event is private.
