method for destroying GtkFileSelection
Hi
here is the handler I use to destroy a gtkfileselection, when CANCEL
button is pushed
void cancel(GtkButton *cancel_button)
{
GtkWidget *window;
window=gtk_wifget_get_parent(GTK_WIDGET(cancel_button));
window=gtk_wifget_get_parent(window);
window=gtk_wifget_get_parent(window);
gtk_widget_destroy(window);
}
Is there a better way than that? (get the parent widget until you get
the window)

I don't believe there's a "create_file_selection ()" variant that
allows to set the initial file, if that's what you're asking for. But
won't a subsequent call to gtk_file_selection_set_filename () after you've
created the file_selection be the same thing?

This works for me:
static void cancel (GtkWidget *w, GtkWidget *data) {
gtk_widget_destroy (GTK_WIDGET (data));
}
where I've connected the callback as follows:
g_signal_connect (GTK_FILE_SELECTION (filebox) -> cancel_button,"clicked", G_
CALLBACK (cancel), filebox);
Works fine, though I'm not sure if that's the way you're suppose
to do it.

Please take a look at "speeding up GtkTreeView?" thread on gtk-app-devel from 11 Feb 2003. There were also discussion about it last year, but I don't remember exactly when. The conclusion was that the only solution was to write custom GtkTreeModel. And that other source of slowness is pango.

I just use CList, because of TreeView being so slow.

Well, here is test sample with simple text renderer (column size is not

this is still not the correct function prototype. it doesn't return a
value. moreover, i think you misunderstand what "data" is. its not the
data that is available to read. its the pointer you supplied in
gdk_input_add(). its your function's job to read the data from the
source. the "data" argument is just there in case it needs help
(e.g. some kind of additional information needed to read the data; not
normally necessary for simple i/o based on file descriptors). a
typical handler would look something like:
int input_callback (gpointer data, gint source, GdkInputCondition cond)
{
char buf[SOME_SIZE];
int call_again = TRUE;
switch (cond) {
case GDK_INPUT_READ:
read (source, buf, SOME_SIZE);
... do something ...
break;
case GDK_INPUT_EXCEPTION:
... do something ...
call_again = FALSE;
break;
}
return call_again;
}

if you want it called again and again, the least you have to do is to
make it return TRUE.

Could you > please tell me how can I convert a GTypeInfo into GTypePlugin? The idea of GTypePlugin is that you provide information to GObject as to how to load your type when necessary. However, you don't need to provide your own GTypePlugin or use g_type_register_dynamic() directly... what the GTypeModule parameter passed to your init() is is basically an implementation of GTypePlugin that is already set up to for you use. Just use g_type_module_register_type() rather than g_type_register_static(). There are multiple examples of this in the provided input modules, or for more examples, you can look at the theme engines in the gtk-engines/ modules. (They generally register two types .. one GtkStyle type and one GtkRcStyle type.)

No application can interpret a text file without knowledge about the character encoding. That's why every sane file format that includes text, defines the encoding or defines how the encoding is specified. There are some reasonable heuristics that can be used to guess encodings but that is outside the realm of GLib. In your case, I'd guess your file is ISO-8859-1 encoded.

AS far as I know, I've built and installed all the dependencies but when I try GTK, I get the following: Peanut:~/gnome/build/gtk+-2.2.1$ ./configure --prefix=/usr Peanut:~/gnome/build/gtk+-2.2.1$ make make all-recursive make[1]: Entering directory `/home/chris/gnome/build/gtk+-2.2.1' Making all in po make[2]: Entering directory `/home/chris/gnome/build/gtk+-2.2.1/po' make[2]: Leaving directory `/home/chris/gnome/build/gtk+-2.2.1/po' Making all in gdk-pixbuf make[2]: Entering directory `/home/chris/gnome/build/gtk+-2.2.1/gdk-pixbuf' Making all in pixops make[3]: Entering directory `/home/chris/gnome/build/gtk+-2.2.1/gdk-pixbuf/pixops' /bin/sh ../../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c pixops.c gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c pixops.c -fPIC -DPIC -o pixops.lo /bin/sh ../../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c have_mmx.S gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c have_mmx.S -fPIC -DPIC -o have_mmx.lo /bin/sh ../../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c scale_line_22_33_mmx.S gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c scale_line_22_33_mmx.S -fPIC -DPIC -o scale_line_22_33_mmx.lo /bin/sh ../../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c composite_line_22_4a4_mmx.S gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c composite_line_22_4a4_mmx.S -fPIC -DPIC -o composite_line_22_4a4_mmx.lo /bin/sh ../../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c composite_line_color_22_4a4_mmx.S gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED -Os -mcpu=i386 -fno-strength-reduce -Wall -c composite_line_color_22_4a4_mmx.S -fPIC -DPIC -o composite_line_color_22_4a4_mmx.lo /bin/sh ../../libtool --mode=link gcc -Os -mcpu=i386 -fno-strength-reduce -Wall -o libpixops.la pixops.lo have_mmx.lo scale_line_22_33_mmx.lo composite_line_22_4a4_mmx.lo composite_line_color_22_4a4_mmx.lo mkdir .libs rm -fr .libs/libpixops.la .libs/libpixops.* .libs/libpixops.* ar cru .libs/libpixops.al pixops.lo have_mmx.lo scale_line_22_33_mmx.lo composite_line_22_4a4_mmx.lo composite_line_color_22_4a4_mmx.lo ranlib .libs/libpixops.al creating libpixops.la (cd .libs && rm -f libpixops.la && ln -s ../libpixops.la libpixops.la) gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../.. -DG_DISABLE_CAST_CHECKS -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED-Os -mcpu=i386 -fno-strength-reduce -Wall -c timescale.c /bin/sh ../../libtool --mode=link gcc -Os -mcpu=i386 -fno-strength-reduce -Wall -o timescale timescale.o libpixops.la -Wl,--export-dynamic -pthread -lgobject-2.0 -lgmodule-2.0 -ldl -lgthread-2.0 -lglib-2.0 -lm gcc -Os -mcpu=i386 -fno-strength-reduce -Wall -o timescale timescale.o -Wl,--export-dynamic -pthread ./.libs/libpixops.al /usr/l

Hello,
I need to add a signal to the GtkWidget so that the callback functions will
take two pointers instead of one. i.e.
foo(GtkWidget *widget, gpointer clientdata, gpointer
datastruct){}
I realize that I need to use gtk_object_class_user_signal_new(), however, I
don't understand how to define a new marshaller for this. The FAQ simply
says "If you want your new signal to have more than the classical gpointer
parameter, you'll have to play with GTK+ marshallers." I'm guessing that I
need to use GtkCallbackMarshal() to define a function, but I can't seem to
find any documentation on what the marshaller functions actually need to do.
Note: I don't have access to the gtk src code on the machine I'm using yet,
so I can't look there for an example
Can anyone help me?
Thanks,
Brooke

How is GdkPixbuf pixel data stored?
Hi
I'm looking to manipulate a GdkPixbuf at the pixel level and have found
that the actual pixel data is not stored in the way I expected.
In order to get the pixel data I have used the following code (where
image is a static GtkWidget declared in the header file):
void pixel_data(GtkWidget *widget, GdkEvent *event, gpointer data)
{
int i, array_size;
GdkPixbuf *image_data;
i = 0;
image_data = gtk_image_get_pixbuf(GTK_IMAGE(image));
array_size = 3 * (gdk_pixbuf_get_width(image_data) *
gdk_pixbuf_get_height(image_data));
for(i=0; i < array_size; i++)
g_print("%d, ", (int) gdk_pixbuf_get_pixels(image_data)[i]);
}
My assumption was that the guchar pointer returned by
gdk_pixbuf_get_pixels() would store the pixel data as an 8 bit int for
the R, G and B channels for each pixel. ie. a 2*2 pixel image with 24bit
colour would print out the following (assuming the image was white):
255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255,
However the following was output:
255, 255, 255, 255, 255, 255, 80, 64, 255, 255, 255, 255,
I then output the rowstride for the image which was 8 (bytes per row)
which prompted me to hack the code to loop 16 times and got:
255, 255, 255, 255, 255, 255, 80, 64, 255, 255, 255, 255, 255, 255, 0, 0,
rowstride: 8
My Question is simply why are there two extra bytes per image row, what do
they represent and what is a rowstride? - the documentation assumes this
knowledge!
I'm using GTK2.0 and redhat 7.3
Cheers

Re: Can I make a IM Module resident?

Re: File Descriptor Input
your problem is that standard input is line-buffered,
so you only get input when ENTER is pressed.
(in the terminal from which you run the program!)
I don't know exactly the behavior you want when you "trap the keyboard".
if you are writing a gui, you must use X windows (eg gtk_widget_add_events() and
connecting to the "key-pressed-event" signal (only works with a toplevel widget!))
if you are writing a ncurses program, there's other functions
you must read about in that library...
in any event, without special calls to tcsetattr to put stdin in "raw" mode,
gdk_input_add( fileno(stdin), ...) is unlikely to be what you want.
the reason why no one responds: keyboard handling is a mess,
and your question seems vague to someone who knows the answer ;)

problem with the new GTK+2.2.1 compilation after crash
Hi, can somebody help me with this, please? I has been compiling the GTK+2.2.1 from source code following instructions on http://beyond.linuxfromscratch.org/view/cvs/x/gtk2.html *./configure --prefix=/usr --sysconfdir=/etc && make && make install* , but the computer crashed during the make or make install commands.

I don't think that GIOChannel has anything to do with the encoding of a string in a file. To GIOChannel, you are dealing with a file. It really doesn't care what's in it. It's just a bunch of bytes to it. To know what kind strings you are reading from the file. (Or even to know that there are even strings in the file.) You'll have to know something about the type of file you are dealing with. For example, you could be dealing with a MPEG file, a JPEG file, a PNG file, an Intel 80386 native DLL, a UNICODE text file encoded in UTF-16, an XML file, a GNU tar archive, etc. What you probably first need is a way to figure out what type of file you are dealing with. And, if you already know that, then you'll probably need a way to figure out what the data in the file is. (This is file dependent though. GIOChannel is at a much lower level that this... so it wouldn't provide an API for this kind of thing.) Hope that helps.

outdated wrong comment in gtkobject.h?
In gtkobject.h I read the following:
/* The GtkObjectClass is the base of the Gtk+ objects classes hierarchy,
* it ``inherits'' from the GtkTypeClass by mirroring its fields, which
* must always be kept in sync completely. The GtkObjectClass defines

void (*set_arg) (GtkObject *object,

GtkArg*arg,
guint arg_id);

* own cleanup. (See the destroy function for GtkWidget for
* an example of how to do this).
*/
void (*destroy) (GtkObject *object);
};
The thing is that GtkTypeClass seems to be typedef'd to GTypeClass, which
seems to consist of a single GType, which in turn is something like a
nsigned integer. So I don't see how it can be true that the fields are
being kept in sync. Maybe this is an old comment and no longer correct?
Thanks for any explanation you can offer,
