How to add a GTKAda?

How to add a GTKAda?

[Marcus F]

I'm using AdaGIDE, and I wanted to take a look at GUI programming, I found GTKAda and have installed it, but I have no idea how to add it to my program in AdaGIDE.

It's supposedly in my PATH, but simply adding use gtkada tells me it can't find it, do I need to specify the path in the USE?

If you're saying "use Gtkada;" without having said "with Gtkada;", then you 
don't know Ada well enough yet to be taking this step. Learn how to use packages 
in Ada 1st and then you'll be ready to play with GTKAda.

If you are using packages correctly, then you need to tell GNAT where to find 
the GTKAda packages and related files. Typically this is done with a "-I" 
command-line switch (see the GNAT documentation for more on this), but how you 
do this through AdaGIDE I don't know.

I used with.
I'm certainly new to Ada (A few days in), but I'm not new to programming, I usually learn best by examples and by altering code, which is why I wanted to play with GTK, I've done minimal GUI programming before in PortablE.

Thank you Jeff, I think that's the info I need to get on the right track.

FWIW:

I learned GTK by making a small app with Glade (the interface generator)
and looking at the generated code. Worked well for me.

1. Rosetta Code has plenty GtkAda examples:

   http://rosettacode.org/wiki/Rosetta_Code

Note that these are GTK 2.x (GtkAda 2.24.x). Don't expect them working with
GTK 3.x (GtkAda 3.4.x). None will. But it is relatively straightforward to
fix them.

I presume, the biggest issue for a beginner would be generic packages
defining signal handlers. They cannot be instantiated deeper than on the
library level. Examples tend to be single source file, which will require
unchecked conversions for a locally defined handler to the library level
callback procedure. (For a real-life project it is not an issue because it
will put this stuff into library level packages.)

2. Refer to GTK documentation and tutorials:

https://developer.gnome.org/gtk3/stable/

GtkAda is thin bindings, so C examples are relatively simple to translate
into Ada. Except for signal handlers which are made Ada way (e.g. type
safe).

3. You should probably switch to GPS. AdaGIDE is nice but not suitable for
large projects. It is much comfortable for GtkAda and other large projects
deploying GNAT project files (*.gpr).

Thank you Dmitry, I did already install GPS, but.. I don't understand it.
I tried new project, typing in code, but I can't compile/build/run, I get a number of errors.

I'll try re-installing tomorrow, maybe I did something wrong when installing.

Please don't quote large portions of the previous messages, when they
are not relevant to the reply. It just makes it hard to find your reply;
we assume you have put replies in the middle some where.

And please try to fix your news reader to not insert extra blank lines.

If you say what the errors are, somebody here can probably help.

good luck.

Stephen, I don't use a news-reader, I'm using the Google Groups website, I have no control over it adding blank lines.

Sure, I'll strip the comments, I don't know what news-reader you're using but I've never had any problems seeing where new parts are and where quoted text is, maybe you should update your news-reader/get a better one?

I'll make a new post about my GPS problems, it's easiest that way.

I try to remove the extra blank lines myself.  It's a huge pain in the keister, but I do it because I'm somewhat obsessive-compulsive.  I don't blame anyone else for not going to the trouble.

Google has made a number of improvements to Google Groups over the years, and it seems like every time they improve it they make it worse.

I think that makes Google Groups a newsreader.

Marcus, Google Groups is what it is; I guess it's not much of a profit
centre for Google, so bugs (particularly the adding-blank-lines one)
aren't going to figure high on their hit list.  I do completely
understand why people use it - I did myself for a long time from work,
where adding non-approved software was a big no-no - and it's good that
they do, keeps the group alive.
