Hi
May be the following is also a way to strip the foot print.
Instead of glibc, use dietlibc, it will reduce a lot of foot print. I
don't know you are working on embedded devices. Even it is very easy to
use also.

Message-ID: <45B6569D 8000100 gmx de>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hello,
as the topic suggests, I am trying to capture a window which should be
printed afterwards.
This is my code:
/* appl_t is a struct created by me which contains "GtkWidget
*print_win",
* the window I want to print. Moreover, appl_t contains gints for the
* width and height of the window */
/* callback for my print button */
static void print_cb(appl_t * appl)
{
values_t *val = &appl->values;
GtkPrintOperation *op;
GtkPrintOperationResult res;
output_print(appl); /* This function creates the window which I want
to print */
op = gtk_print_operation_new();
gtk_print_operation_set_n_pages(op, 1);
gtk_print_operation_set_unit(op, GTK_UNIT_MM);
g_signal_connect(op, "draw_page", G_CALLBACK(draw_page), appl);
res =
gtk_print_operation_run(op,
GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
NULL, NULL);
}
}
static void draw_page(GtkPrintOperation * operation,
GtkPrintContext * print_context, gint page_nr,
appl_t * appl)
{
gdouble print_width, print_height, scale;
cairo_t *cr, *cr_win;
cairo_surface_t *surface;
values_t *val = &appl->values;
/* create a surface of the print window */
cr_win = gdk_cairo_create(appl->print_win->window);
/* get width and height of the print window */
gdk_drawable_get_size(appl->print_win->window, &(val->width),
&(val->height));
gtk_widget_hide_all(appl->print_win);
/* create the cairo surface for cr_win */
surface = cairo_get_target(cr_win);
cairo_surface_reference(surface);
cairo_destroy(cr_win);
/* get width and heigth of print_context */
print_width = gtk_print_context_get_width(print_context);
print_height = gtk_print_context_get_height(print_context);
/* transform the print_context into a cairo_context */
cr = gtk_print_context_get_cairo_context(print_context);
scale = (gdouble) print_width / val->width;
/* scale, keep aspect ratio */
cairo_scale(cr, scale, scale);
cairo_set_source_surface(cr, surface, 0., 0.);
cairo_surface_destroy(surface);
cairo_paint(cr);
}
The problem is that the window is often captured with the print dialog.
Furthermore, the window is sometimes "incomplete". The PDF/PS output
shows just parts of the window - it seems that print_win is captured
before it is completely rendered.
Questions:
- Are there any better ways to achieve what I want?
- Can I capture the window without showing it?
Regards,
Fabian

Hi everyone,
I have a combobox that I am creating with gtk_combo_box_new_text(). Is
there a way to change the background color to something other than gray?
Thanks-

Can anybody help me with the following errors?
** (printing:10547): WARNING **: Error getting printer list: Too many
failed attempts
** (printing:10547): WARNING **: Error result: Too many failed attempts
These 2 warning are output whenever the print dialog recieves a mouse
click on any widget in the window. The dialog returns
GTK_PRINT_OPERATION_RESULT_APPLY and the print operation is a success,
but still those warnings have me curious. I do not have a printer
installed but am using the "Print to file" printer.
Dialog was run using:
res = gtk_print_operation_run (operation,
GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
GTK_WINDOW (w->window), &error);

Greetings,
Can any one tell me or give me some links to know how I can reduce the
footprint of GTK.
Actually I want to remove some widgets (like frame, color selection,
file selection etc) which I am not using in my application.
Also I want to know that if there is any other alternate way to reduce
the GTK footprint.

Hi,
I am not sure, to what level you want to strip the GTK Widgets and also
the
purpose behind it.
To port GTK over Mobile phones LiPS forum is trying to strip the
unwanted
widgets by applying a Patch to GTK.
Maybe you can apply LiPS patch to get rid of most of the unwanted and
redundant widget.
There is another work around. Just set flags on these widgets in
Makefile
and also on Gtk Code wherever required.
My advice, Follow LiPS patch.
Hope, this helps in some way
Rgds,
Madhu

not sure if this is what you mean, but in the debian-installer (hich is
gtk/dfb based) we provide a set of stripped libraries using the mklibs
tool.
This allows us to save up vakuable space on installation media.

Hi...
Ya even our requirement is to save the space on installation media.
Can't we get a copy of mklibs tool for FC5 / FC6 as we cant use that
debian-installer.

Richa

Do you mean disk space? Or memory space? On what platform? On most
modern platforms with virtual memory, presumably only those parts of
GTK+ that your code actually uses get paged in.
Anyway, how hard can it be to experiment? Drop stuff you don't want
from the gtk Makefile(.am), try to build gtk+, and see what further
(small?) changes are needed to successfully produce a leaner gtk+
shared library. If you do this and distribute your resulting binaries,
make sure to use a different name for your shared libraries to avoid
confusion!

For our embedded application, the memory footprint allowed, maximum

That sounds awfully tight.
a) We calculated footprint for small application on Windows. It boils
down to around 7.3MB.

This is not the *memory* footprint you mentioned above. It is the size
on *disk* of the DLLs, which is quite another thing.
b) On Linux it is 5.3MB

You forget to include here the png and zlib libraries and image
loaders, if this list is supposed to be comparable. And anyway, just
looking at the DLL and .so sizes is mostly an exercise in futility.
We wanted to remove the widgets which are not required by our
application. Is their any procedure to reduce footprint of GTK+,
where
we can trim down gtk, gdk, glib, pango, Cairo???
You presumably do this as part of your *work*? I mean, like, you get
paid to do this? I don't. Why don't you experiment? Why don't you have
a look at what other companies have done to put gtk+ (and GNOME) on
embedded devices. maemo.org is one place to look at.
