Hi wallyg!

Thanks for testing the headers and for your report. Sorry for your trouble.

It seems that by any reason some old headers gets included and cause the duplicated definitions. I'll check this, although it isn't importand for the next FB release (since all old headers will get removed). It may take some time.

Here's how you may continue:
  • rename your gtk folder in C:\FreeBASIC\inc\ (ie -> gtk_old)
  • copy again the gtk folder from the Gtk.7z to C:\FreeBASIC\inc\.


If you like, you may try another method first. Just rename (or remove) the C:\FreeBASIC\inc\gtk\glib.bi file.

Thank you. I renamed the inc/gtk folder to inc/gtk_old and reloaded Freebasic and replace it with your *.7z files and it works great now. Thank you very much for getting this to work for me and all of us in this group. Your work is greatly appreciated.

Aha. Didn't know that dbus isn't available for win32. (What about win64?).


http://sourceforge.net/projects/windbus/


It's available all right but gio uses gdbus.

I looked up the error mesage I got when using gtk+ 3 specific code.

Code: Select all

static gchar *
get_session_address_platform_specific (GError **error)
{
  gchar *ret;
#ifdef G_OS_UNIX
  /* need to handle OS X in a different way since `dbus-launch --autolaunch' probably won't work there */
  ret = get_session_address_dbus_launch (error);
#else
  /* TODO: implement for UNIX, Win32 and OS X */
  ret = NULL;
  g_set_error (error,
               G_IO_ERROR,
               G_IO_ERROR_FAILED,
               _("Cannot determine session bus address (not implemented for this OS)"));
#endif
  return ret;
}


"..not implemented for this OS" being the interesting part.

The above function is part of GDBus - GLib D-Bus Library. Right now there just are not that many Gtk+ developers working on the win32 back end.

Looking at the dated glib/gtk+ binaries at ftp.gnome.org I do not think there will be a solid gtk+ version 3 release on win32 any time soon.

If libs like goocanvas start using gtk+ 3 stuff that is not portable then gtk+ might become less usable to many a fb programmer. Which (of course) does not mean there should not be gtk+ bindings for the fb programmers using Linux.

IMHO it's a common problem with ported *nix packages. Usually they are not really designed portable (to non *nix. They often are called "portable", but that is internal *nix portability), and the big decisions have been made before the other platforms are considered.

Yes, see wallyg post above ... We cannot mix the old and new files (because glib.bi gets included twice).

Either
  • rename or remove .../freebasic/inc/gtk/glib.bi or
  • rename or remove the complete .../freebasic/inc/gtk/ folder and install the new files again

Good luck!

@VANYA, thanks for your report! It seems that you've tested all examples. Good job.

Just to make it clear:
VANYA wrote:... compilier: Latest stable ...
= fbc 0.23?

Regarding your tests
  • Tutorials/text.bas:
    No such file in my examples? (It seems that you mixed old examples and new headers.)
  • Glade_gui.bas and glade_xml.bas:
    No such files in my examples? I removed them because libglade is deprecated. They're replaced by .../examples/libraries/Gtk/GtkBuilder.bas.
  • list.bas, tree.bas, filesel.bas:
    These widgets are deprecated. That_s why I moved the examples in to the .../examples/libraries/Gtk2/Tutorials_deprecated folder. Use GtkFileChooser, GtkListView and GtkTreeView instead. (Find examples for GtkFileChooser and GtkListView in .../examples/libraries/Gtk/GtkBuilder.bas by using GtkBuilder2.ui.)
  • spinbutton.bas:
    Which GTK version do you use? (Compile and execute .../examples/libraries/Gtk/GtkVersionCheck.bas.) Did you compile the updated example from the archive in the first post here?
  • gooCanvas:
    I don't understand '... the brake Scroll'. (And I need info about GTK / Cairo versions.)

fbc 0.23 ?


Yes.

I tried 0.24 for all examples:

cannot find -lgio-2.0
cannot find -lpangocairo-1.0


you mixed old examples and new headers


Yes. But the headers I did not mix

/examples/libraries/Gtk/GtkBuilder.bas


If you include the line: #DEFINE __FB_GTK3__ ,that:

If you do not include a string # DEFINE __FB_GTK3__, then compiled and executed, but while the mouse will not spend on widgets, ListView and another widgets, does not fill the rows.

I didn't test 0.24 yet. It seems that your version still ships the old GTK 2.08 binaries (older than 5 years). You can use
    #DEFINE __TJF_GTK_OLD__
before #INCLUDE ONCE "gtk/gtk.bi" to omit loading these new libraries.

VANYA wrote:

My headers are similar to the original GTK C code. When a function is removed in the C headers it'll also be removed in my FB header. That's why my headers may not contain all function calls from the old examples. And that's why I made new / updated examples for the new headers.

GTK3 uses a different settings concept. It seems that your installation isn't complete. (The installation from 'http://users.freebasic-portal.de/tjf/GTK/Gtk_Bin.7z' runs on a XP SP2 system here - 95%.)

Unfortunately I cannot recommend a link to an windows GTK3 installer, since I didn't find one yet. The binaries mentioned above are partially compiled by Galeon some month ago and partially downloaded from http://www.gtk.org.

..., but while the mouse will not spend on widgets, ListView and another widgets, does not fill the rows.

This also sounds like an installation issue. GTK is missing the information how to render these lines / rows (, they should be provided by a GtkTheme). I recommend to reinstall GTK2 by this bundle and mind all instructions regarding the setup.

The system had two different versions of GTK and probably had a conflict. I removed both and installed from the official website the latest version. Everything was normal. There are examples (not yours) that do not work.
Your examples work and are very helpful, thank you.

You're welcome!

BTW:
I don't use GTK like it's shown in most of the examples. I design my GUIs with Glade3 and save them as GUI-XML-file. Then I use GladeToBac3 to generate (or update) a FB code frame. Then I start programming in FB by extending the code frame.

The code frame looks similar to the .../examples/libraries/Gtk/GtkBuilder.bas example. But it's separated in several files so GladeToBac3 can add (or remove) signal handlers as needed.

For me it is too early,I must first learn how to make themselves functions of GTK, then I can create using the visual editor

When I started coding approx 27 month ago, I had no clue neither about FB nor about GTK. By learning with Glade3 it was much easier to understand the GTK concept (packing into containers, variable placing, ...). With Glade3 I could learn by trail and error. It was much faster than studying lots of documentation (since I wasn't keen on English computer terminology).

Anyway, good luck for your project(s).
