[Sami Evangelista]

good morning everybody

i am going to develop an application with a graphic interface lying on 
gtkada which i don't know at all.
Does anybody know where i could find a tutorial or a reference manual 
about gtkada?

thanks for any help.

There is a reference-manual for GtkAda which comes along with the library
itself.

You might also want to have a closer look at glide, a GUI-builder for
Gtk (and even GtkAda), those giving you much help in developing GUIs.

There are some examples for GtkAda in the exampels-directory.

After all, using GtkAda is really nice and straight-forward. You can even
learn it by reading the include-files (in most cases, *.ads is sufficient,
they are well-documented and because of strict typing the API is eay to
understand for programmers)

Besure to understand the way you pack widgets in Gtk+/GtkAda. One do not
use fixed posistions as f.ex Delphi does.

Sure, glade. Sorry, my fault.

No, I was dealing around with OpenGL/Mesa/Glut and Glide the whole day,
so I mixed things up.

Yes. I'd like to put emphases on this. Having those unfixed widgets give
you much freedom in resizing the window. On the other side you'll have
to use paddings if you want some space between objects.

Yes, but you also have border width.

I'm struggling with a scrolled_window and a Clist inside. I would like to
have a size not smaller than 80 pixels. I guess it's not really possible
except to make the parent-window that large (by default) so there are
still 80 pixels left for the scrolled_window.

Now it's much smaller because other stuff in the window takes so much
space. It would be nice to say: Set_Size_At_Least(scrollwindow1, 80);

Why do you put a Clist inside a scrollwindow?

I want to scroll the list. Is this wrong? gtk-clist.ads says:

--  You can add scrolling in a Gtk_Clist by adding it in a Gtk_Scrolled_Window.

No sorry I got a bit confused. I thought you had added a scrolledwindow
in glade and then added a clist into it. This is wrong because glade
will add the scrolledwindow for you automatically when you choose and
add a clist.

But I guess you don't have two scrolledwindows :-)

Hmm. I would view this as a bad idea, unless Glade says clearly "Would
you like a Scrolled_Window for that", and I get to say "no". There
_are_ times when I _don't_ want scrolling. For example, if I want to
be sure the entire list is immediately visible (yes, it is then my job
to be sure it is small enough for the available window space).

> But I guess you don't have two scrolledwindows :-)

And since I'm familiar with building Gtk GUIs without Glade, I would
probably end up with two Scrolled_Windows every time :).

Then you set the V Policy to Never. I think it is better that
scrolled_window gets added automatically in all the cases it is
necessary as in 90% of the cases you need scrolling and in the rest you
can either set V Policy to Never (and H policy) or remove it with
cut'n'paste. :-)

The Widget-tree window is nice to see the structure :-)

This is getting a little off-topic, but I'm doing similar things. I
assume you are using GtkAda (not some other language binding :).

I also have a Clist inside a Scrolled_Window (so I can scroll the list
when it is too big). I did nothing to specify a minimum size; it seems
to request enough to show one line.

You should talk in terms of lines (of information), not pixels. The
user may change their default font to something much larger, in which
case your pixel size will be wrong.

Do you want the minimum size to be more than one line?

If the number was lines of information, I agree that would be useful.
There may be a way to do this with Gtk; I'm still new.

Yes. And that's the problem. One line is not enough. It's a list, not
a row :)

I agree that specifying the number of lines would be a nice way.

It depends :) It should be, but I've not already heard about GtkAda2.0
for Windows. But you could do the world a favour if you compile it.

[Sami Evangelista]

hello
is it possible to connect a handler to a drawing_area when the user 
click on this drawing area. I have tried to connect my handler to the 
"button_press" signal of the Gtk_Drawing_Area like this :

---------------------------------------------------------
Widget_Cb.Connect(Gtk_Widget(Current_Da), "button_press", 
Widget_Cb.To_Marshaller(On_Sub_Net_Button_Press'Access));
---------------------------------------------------------

it compiles well but at the execution the follwing error occurs :

---------------------------------------------------------
Gtk-WARNING **: gtk_signal_connect_full(): could not find signal 
"button_press" in the `GtkDrawingArea' class ancestry
---------------------------------------------------------

You'll get better help on GtkAda from the GtkAda mailing list. See
http://libre.act-europe.fr/GtkAda/
(way down near the bottom) for instructions on subscribing.

The list of signals valid for each widget is given in the Ada package
spec, as comments. So read the spec for Gtk_Drawing_Area. I don't have
GtkAda installed here, so I can't do that right now.

thanks for your help

gtk.drawing_area spec says :
---------------------------------------------------------

--  * Connect it to "button_press" and "button_release" events, when you want
--    it to react to user input. Note that you need to set up the event mask
--    with a call to Gtk.Widget.Set_Events.
---------------------------------------------------------


so i dont understand why my call to connect doesn't work

Sounds like a bug in the specs. Or, maybe your code doesn't do what
you think it does :). Post the code on the GtkAda mailing list.

But go here: http://gtkada.eu.org/ or to the US mirror at

We've started the documentation with GtkAda 0.6
The current version of GtkAda is 1.2.1 and contains many improvements
and documentation. I would strongly suggest to switch to this version
unless you have very good reasons to stay with an old beta version of
GtkAda.

Visit our web site to get the 1.2.1 version:
