Ruby Forum Ruby-Gnome 2 > PrintOperation on windows

hi,


ruby -e "require 'gtk2';p \"gtk:#{Gtk::VERSION.inspect},
binding:#{Gtk::BINDING_VERSION.inspect}\""
on a gentoo(ruby 1.8.6 (2008-03-03 patchlevel 114) [x86_64-linux]):
"gtk:[2, 12, 11], binding:[0, 16, 0]"
on the XP(ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]):
"gtk:[2, 10, 6], binding:[0, 15, 0]"   (strange it was installed by
ruby-gnome2-0.16.0-1-i386-mswin32.exe)

anyways, my problem is with printing on windows:
on the gentoo the following presents the dialog, but on the XP it just
stops responding, and hangs forever, no output.
ruby -e "require
'gtk2';Gtk::PrintOperation.new.run(Gtk::PrintOperation::ACTION_PRINT_DIALOG)"

do i miss something?
is it supported?
is there something i could do to make it work?

thanks in advice,
balint

ruby -e "require 'gtk2';Gtk::PrintOperation.run_page_setup_dialog"
also does not work.
but
ruby -e "require 'gtk2';p Gtk::PrintOperation.new.status"
#<Gtk::PrintOperation::Status initial>
and
ruby -e "require 'gtk2';p Gtk::PrintOperation.new.job_name"
"-e job #1"
works. is it just the dialog?

Kou, can you please confirm this situation? is it not implemented, or am
i doing something wrong?
thanks in advice

I'm sorry but I don't have a Windows environment...

Could you try with the current GTK+?

  * Download the current GTK+:
     http://www.gtk.org/download-windows.html:
        http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.12/gtk+-bundle-2.12.11.zip

  * Move the GTK+ bundled with Ruby-GNOME2:
     C:\\ruby\lib\GTK -> C:\\ruby\lib\GTK-Ruby-GNOME2

  * Extract the current GTK+ to C:\\ruby\lib\GTK

hi,
i tested the dialog, it's the same :(
is there anything else i should try?

If you have a GTK+ build environment (and you can write C)
on Windows, please try the same code in C. If you can
reproduce the problem in C, it's a GTK+ problem. Otherwise,
it's a Ruby/GTK+ (or Ruby/GLib) problem. Can you do it? If
you can't write C, I will be able to write it.

Or I will be able to build a test program binary on
my Debian GNU/Linux environment. (cross compile)

Here is a test program built from the following code:
  http://ruby-gnome2.sourceforge.jp/gtk-print.exe

#include <gtk/gtk.h>

int
main(int argc, char **argv)
{
    GtkPrintOperation *operation;
    GtkPrintOperationResult result;
    GError *error = NULL;

    gtk_init(&argc, &argv);

    operation = gtk_print_operation_new();
    result = gtk_print_operation_run(operation,
                                     GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
                                     NULL,
                                     &error);
    if (error) {
        g_warning("%d:%s", error->code, error->message);
        g_error_free(error);
    } else {
        g_print("RESULT: %d\n", result);
    }

    return 0;
}

this is the error:



but i have c:\ruby\lib\GTK\bin\libglib-2.0-0.dll

ops, it runs if i copied it to c:\ruby\lib\GTK\bin\
it presents the nice printer chooser.
thanks

yes, it presents the printer chooser, i did not go further.
now i tried, and was able to setup a new printer from it, and was able
to print to file from it. so i think that works as your gtk-print.exe
in the ruby-gtk2-demo there is no printing.

thank you

Here is a "Printing" sample in Ruby. Please put it to
gtk/sample/gtk-demo/ directory, run main.rb and try
"Printing" sample.

"not a Gtk::MessageDialog::ButtonType" error i get in line 26
i tried replacing the buttons parameter with
Gtk::MessageDialog::ButtonsType::CLOSE, and with 2, but no luck, same 
error.
so i replaced the dialog part with a "p $!.message"
and if i press the print button now i see: "not a Gtk::PaperSize::Unit"

this line generates the error, around line number 60
operation.unit = :points

so i removed that line, i wanna see any printings now, don't care if
it's not calculated correctly.

but than:
"not a Gtk::PrintOperation::Action" in line 63
by the line: operation.run(:print_dialog,self)

so i replace :print_dialog with 0
and we get to the begining of the problem. it hangs, and does not
present the dialog.

There was a patch applied by Kou in latest trunk. Can you check if this 
works?

i can currently compile it on linux.
if you guide me in compiling it on windows, i'll do it.

This wiki entry can help you:
http://ruby-gnome2.sourceforge.jp/hiki.cgi?cmd=view&p=compile_mingw&key=win32

If you use MinGW this should work at least on the machine on which it is 
compiled.

someone please update the rg2 wiki on installing on windows:
i ran into rcairo not configuring:

~/rcairo-1.6.3
$ ruby extconf.rb && make && make install
checking for GCC... yes
checking for cairo version (>= 1.2.0)... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.


~/rcairo-1.6.3
$pkg-config.exe --cflags gtk+-2.0
Package pixman-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `pixman-1.pc'
to the PKG_CONFIG_PATH environment variable
Package 'pixman-1', required by 'cairo', not found

this link helped me out:
http://www.nabble.com/pixman-1-was-not-found-in-the-pkg-config-td16842574.html
i've built http://cairographics.org/releases/pixman-0.10.0.tar.gz with
the following:
./configure --prefix=/MinGW && make && make install

then in the rcairo source:
export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/C/MinGW/lib/pkgconfig/"

$ pkg-config.exe --cflags gtk+-2.0
-mms-bitfields -Ic:/GTK/include/gtk-2.0 -Ic:/GTK/lib/gtk-2.0/include

-Ic:/GTK/include/pango-1.0 -Ic:/GTK/include/glib-2.0
-Ic:/GTK/lib/glib-2.0/include -Ic:/GTK/include/freetype2

but than i ran into:

$ make

so i extracted include/cairo/*h from cairo-dev-1.6.4-2.zip into
MinGW/include/
and make of rcairo finished
make install succeeded

for making rg2 modules(like pango,gdkpixbuf, and finally gtk and atk) i
have to export 2 variables:
export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/C/MinGW/lib/pkgconfig/"
export CAIRO_PATH=/home/balint/rcairo-1.6.3/

testing:
require 'gtk2'
Gtk::PrintOperation.run_page_setup_dialog

presents the dialog. :)

so my question: how do i deploy this mess onto other windows machines?
zip/unzip everything?
or should i wait for a windows release of rg2, which includes the
working PrintOperation?

thanks for your help

You can use GTK+ package on gtk.org:
  http://www.gtk.org/download-windows.html
  http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.12/gtk+-bundle-2.12.11.zip

And you can use PKG_CONFIG_PATH environment variable and
--with-override-variables option:

  $ PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/C/GTK/lib/pkgconfig/" ruby 
extconf.rb --with-override-variables=prefix=c:/GTK
