GTK is an excellent toolkit, and it offers very decent cross-platform operability. But there are a few things to watch out for. First of all, yes, you need a gtk+ runtime on all platforms. Glade is basically a design tool, not a substitute for the gtk libraries. Then there's an issue with gtk versions. The latest and greatest works fine on GNU/Linux and (I think) Windows XP and related OSs. It doesn't work on win98 -- for that you have to back up to an earlier version. And GTK on Mac OS X is a bit fiddly. There's a "native" OS X verson of gtk, but it's not stable yet. The alternative is running the X11 version on OS X, which is quite doable but requires quite a lot of setup. -- Allin Cottrell Department of Economics Wake Forest University, NC ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Fortunately, there some quite good package distributions that drives the effort to a bare minimum, being reasonably easy to setup GTK+ on OsX right now. It comes to my mind the Fink project, http://fink.sourceforge.net/ . I've compiled some Linux developed GTK+ applications on OsX with fink's GTK+ packages, with success in all cases. There are some other library stacks that let you use GTK+ on OsX as OpenDarwin's DarwingPorts, reachable at http://opendarwin.org/ http://darwinports.opendarwin.org/ . With those distributions being quite mature, and the forthcoming of the native GTK+-cocoa port, the future of GTK+ on OsX is not just bright but sparkling. Just a counsel if you're going to develop multi-platform GTK+ apps: glib is your best friend, use it as much as you can.

Can I hide password in config file?
Hi, I'm using the GLIB Key-value file parser (http://developer.gnome.org/doc/API/2.0/glib/glib-Key-value-file-parser.html) to create or read from a config file. The contents of this file is servername, port, some other things and a password for accessing this server. The user can use an options-dialog in my application to set those data and my application will write it to this file, so he hasn't to bother with the syntax. At the moment the password is clearly visible, as it is a normal key value. I'm looking for a way to protect the password. It should be stored in that file but like /etc/password. I have no clue how to do that. Any ideas? Thanks a lot ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

I would caution you to understand your user community. I work on an open source cross platform product (CvsGui). The person that maintains the Mac port does not use the Gtk implementation, but has written a native one. Serious Mac users disdain most cross-platform tools, because most apps end up feeling like Windows applications, and the native Mac look and feel is quite different from that. If your app has a restricted user community and they are okay with Gtk apps, then fine.

Thanks, Santhosh. In reply, there are some fundamental differences: - While Glade and Gazpacho are UI-builders, RADiola aims to be an application builder. This includes variables and subroutines, among other things. - Glade and Gazpacho are highly tied to GTK, and so are their users. RADiola is being made with GTK, but the user-created applications might adopt any other toolkit and various programming languages. - Users of those and other GUI builders still have to dominate a programming language and an API for creating an application, while RADiola will try to abstract all this "coding stuff" as much as possible. > I dont think that people would start working on your project just with > the concept... You need some code which atleast has something in it... > and it should convince the users to work on it... Sure. When I finish the planning stage (which includes the Development Guide) I will start writing code. It is just a big boost to know that there is people who has interest in a software like RADiola. I would not expect that anyone would do a "okay, lemme write yer code fer ya". But I will be glad to send the documentation, interface files, etc., and discuss them with anyone who might be interested. Best regards! Fabricio Rocha Brasilia, Brasil ___ Novidade no Yahoo!

It should be stored in that > file but like /etc/password. You cannot store it `as in /etc/passwd', read crypt(3) for details (assuming password as it was stored in /etc/passwd where it is not stored anymore). The short reason is that the password is not intended to be obtainable (to reveal it one has to search the password space). Your app does not need to check the passwords, it needs to obtain the passwords. And if your app can do that, anyone can. So you have the following possibilities: - do nothing, just make sure the file is 0700 (this advice applies to all following too) - use some mild obfuscation like Base64 (GLib 2.12 can do Base64) to make yourself feel better - encrypt the passwords with a master password the user has to enter to decrypt and obtain them -- see e.g. Firefox Yeti -- Anonyms eat their boogers. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

That says a lot. If you were an experienced programmed, you would know better that the kind of program you are aiming for is a lot hard. Specially the "GUI-oriented programming" stuff. It's already hard enough to have just a visual GUI-builder, let alone a visual code-builder. good luck, but if i was to give any advice, it would be to aim lower... and release actual code.

Load modules in Gtk+ IMModules
Hi all,
Now, I'm developing my own text input method module by using the
GtkIMModule.
My own text input method is seperated to two major component, one is
input engine and the other one
is input helper. Input engine tooks response for retrieving the correct
candidates for users inputs, while the Input
helper charges for displaying them to the screen. And various input
engines and input helpers are supported.
my own text input method module here, plays the part of manager to
choose the proper input engine and input
helper for the current user. So I want my module can load the need
engines or helpers module dynamically.
The specific GtkIMModule is loaded as a module when the input method is
selected, so all types in the module
will be register use g_type_module_register_type(). I load my engines
and helpers module in the class initizlize
function and call g_type_module_use() and unload them in class finalzie
function. Here is the problem, the first time
I select my own input method module from the pop-up menu of a editable
widget, it works perfect. But after I change
to other input methods and re-select it again, an error occurs:
Two different plugins tried to register 'x'.
is a widget class defined in the helper module. Here are piece of
my code:
static void
gtk_im_context_ptim_init(GTypeInstance * this, gpointer class)
{
GtkIMContextPTIM * this_ptim = GTK_IM_CONTEXT_PTIM(this);
...
this->helper_module = g_object_new(PTIM_TYPE_HELPER_MODULE, NULL);
this->helper_module->path = g_strdup(module_path);
g_type_module_set_name(G_TYPE_MODULE(this->helper_module),
this->helper_module->path);
if (g_type_module_use(G_TYPE_MODULE(this->helper_module)))
{
gboolean res = TRUE;
if (this->helper_module->helper_moudule_init)
{
res =
this->helper_module->helper_moudule_init(G_TYPE_MODULE(this->helper_module));
}
return res;
}
return;
}
...
static void gtk_im_context_ptim_finalize(GObject * this)
{
GtkIMContextPTIM * this_ptim = GTK_IM_CONTEXT_PTIM(this);
GtkIMContext * super_class;
...
g_type_module_unuse(G_TYPE_MODULE(this_ptim->helper_module));
/* Super class finalizatoin. */
super_class = g_type_class_peek(g_type_parent(GTK_TYPE_IM_CONTEXT_PTIM));
G_OBJECT_CLASS(super_class)->finalize(this);
return;
}
The PTIM_TYPE_HELPER_MODULE is a sub-class of GTypeModule defined by
myself to implement a specific helper module.
helper_moudule_init() register all the types unsed by helper widgets.
So, could anyone give some advices about the problem?
Best regards,
Nan Ye

Re: RADiola, a GTK RAD tool
Maybe I can give some help on RADiola. My suggestion would be to get the bare GUI you have done, compile and release it so that there will be a skeleton. There also is another issue I thought about which is the language support. Excuse me if you wrote something about this already in the documentation released but I did not have time to go through it in detail. My idea was as follows: Since you are aiming at a tool which makes application development easy, I would suggest picking a suitable language (or even a set). Something like python might be quite easy to handle. However the language binding can be done as some sort of plugin which is dynamically loaded. What were the intentions in this direction?
