adding some more example to Ada GTK on wiki

adding some more example to Ada GTK on wiki

[Nasser M. Abbasi]

Is it possible for some Ada expret in GTK to add few
examples on using Ada to make GUI in this section:


http://en.wikibooks.org/wiki/Ada_Programming/Libraries/GUI/GtkAda

There is only one small 5 lines examples there.

I want to learn using GTK to make GUI in Ada, but there seems to be
few examples to learn from out there.  I am talking about
small examples to learn from, not some large app.


Thanks

Unfortunately useful GTK examples cannot be small. You can find GtkAda
sample code in:

1. GtkAda distribution, see

    <GtkAda-install-dir>\share\examples\gtkada

2. In GtkAda contributions, see the subdirectory

   test_gtkada

In order to learn GTK read this:

   http://library.gnome.org/devel/gtk-tutorial/stable

It is C, but GtkAda is quite thin.

Also, search for "GtkAda tutorial" in your favorite web search engine.

Also read the GtkAda User's Guide provided with GtkAda (on Debian,
package libgtkada2-doc; see
/usr/share/doc/libgtkada2-doc/gtkada_ug/gtkada2_ug.pdf).

Thanks for the link. Very well done webpage.

I see that one can use Glade with Ada to design a GUI.

I think, for me, this was always easier to do,
than to layout components directly by writing code. So, good
to know this option is there. ofcourse one needs
to learn GTK Ada also to work with the generated code.

GUI designers can save much time. I now use Matlab,
and it has a nice GUI designer called GUIDE, which I
can use to make GUI's using it very fast, better than
having to code all that myself. Easier to move and change
things on the screen looking at things than using
some layout manager in the code, for me it is anyway.

btw, in your PDF files (very well done btw), the images
seem to not have sharp resolution on them. In PDF
I can zoom in to read the text on the images, but
at normal resolution (100%) or when I printed them,
the images are not sharp. Not sure how to added the
images to your document, but thought to mention this.

thanks again,

Hi Nasser

Images in the PDFs are transparent background GIFs.  Perhaps one of
the GtkAdaers can tell me how to improve on the resolution.  I don't
know!

Personally, I hate code generators.  All very well for creating the
first version, but you will pay for it if you try to modify the code.
Convenient they are!  Software Engineers they aren't!

Anyway, I'm glad you find the stuff useful.

I am not sure what software you used to make the PDF files. It looks
too good to be from Microsoft word :), and it does not look like latex
either. I use PNG images, add them to my latex document, and generate
PDF use pdflatex, and resolution always looked as original.

So, may be you can PNG.

Well, the trick is not to have to modify the code by hand, but
use the GUI builder always to change the GUI layout.

I tried both methods, and I just can't go back to coding GUI by
hand any more. What used to take me days, I now do in 1-2 hrs.

Any way, whatever works for one I guess.

Yes, very useful web page.
thanks,

Well, that depends on the kind of GUI you are designing. Generators might
be useful when you have a fixed layout and a very limited set of widgets
grouped in dialogs. I doubt they will give you much help with tree views,
cell renderers and text buffers. Even less if you drop dialogs.

Well then, don't do that!
