I would find it more natural if ’stable’ points to the latest stable - in this 
case alternative c.
Ie the last stable v2.

I spent a bit more time concentrating this last year on recovery for

going to swing the pendulum even more to always connected server based 
tech which is Gnoga’s big angle. I have a few ideas I plan on 
exploring using Gnoga (and also finishing up a form builder for 
Gnoga), but I would like to ask some opinions on the following:


I am considering rewriting Gnoga in a language other than Ada (yes I 
love the old girl but for reasons I don’t want to debate she has 
terminal cancer), what other language would appeal to any of you?


I think that if Gnoga is to have the attentions it really deserves, then 
a language with really high user community,


and one that is still fairly sane.

I can only think of

* Python - hated for its whitespace but otherwise ok

* C# - hated for its problems with other curly brace languages. But it 
also has some nice features,


and its now cross-platform for at least some OS:es/cpus .

I did develop a non-trivial application using rabbitmq, and databases, 
in VS2017,


scp()ed the solution to a debian 8 box and did

dotnet restore ; dotnet build ; and then it ran as supposed to

At work, we sometimes (when tasking) use the pattern below.

At the end there is a client package with procedures A and B which both

may affect the same resourse.

But both start with grabbing a common semaphore which

will be autmatically released when out of scoope.

This way we use the same protected object but with no blocking
operations in it.

But this is perhaps what you meant with mutex operation?

There are packages Semaphores and Semaphores.Controls to enable this.

No.
I use Notepad++ from widows, via

And I use gnatmake to compile, from an ssh shell to that box.

However, gprbuild is about to take
gnatmake's place, so using gnatmake instead may or may not work in the

[Gnoga-list] tabs and cards

[Björn Lundin]

Hi!
I am slightly confused about the difference between the
card and the tab in Gnoga.Gui.View.Card

I'm thinking of doing a small application that needs
a menubar on top, and some tabs that display different data.

Or is the tabs really what you click - the menubar items - and
the cards the rest of the pages ?

Does anyone have an example of a simple tabbed application?

I could not find any example within the distribution

Lapsed_Image  : Gnoga.Gui.Element.Common.IMG_Type;
Matched_Image : Gnoga.Gui.Element.Common.IMG_Type;

However, the server holding the images are
creating new images every 10 minutes in a cron job.
The images are diagrams, created with gnuplot,
and published via https

So, how can I make gnoga reload the images ?

How do I add scrollbars to a view?
My main view needs them - it most likely obvious-
but I can't find a way to make them appear.

Both browser works on /boot.html. Everything else fails. Also with

Note that it worked before (as in a week or two ago)

Mobile broadband (4G)

 With a satellite network there is a large lag and some satelite
 services I know use extensive proxy and compression schemes that
 would break things, but on a clean internet connection I can't
 imagine why nothing would work unless a problem at the browser
 level.

But IceWeasel, that is a virtual guest in this W7 box, uses the same
connection.

Yes. I looked at the multi-connection one,

and I got somewhat confused of different meanings
of 'view'

In the tutorial, 'view' is a _part of_ 'App'

It confuses me a lot (yes - simple mind)

I really like to see a multi-app sample

 If you are not going to set any handlers on the table elements you
 could also do everything static and just let the child elements of
 the table finalize right after creating them (this doesn't remove
 them from the DOM, you just have no more access to them unless you
 attach to them again).
 
 At library level: Result_Table  :
 Gnoga.Gui.Element.Table.Table_Type;
 
 Say in some procedure Fill_Me.
 
 Row : Table_Row_Type; ... for i in 1 .. Last_Result loop declare 
 Col : Table_Column_Type; begin Col.Create (Row, Result (i)); end; 
 end loop;
 
 Then you can use the Result_Table.Inner_HTML (); to erase the
 children in the DOM and start over and call Fill_Me again.
 

This works very well for my purpose


 
 I then tried View.Result_Table.Remove; View.Result_Table.Create
 (View);
 
 
 Create in the above code is invalid, i.e. View.Result_Table exists,
 in this case in the browser (although not in the DOM) and on the
 Ada side.

Yes I noticed that...


 Remove removes the entire table element from the DOM but it still
 exists in the browser's gnoga cache.

And this too

 You could put it back using View.Result_Table with
 Place_Inside_Top_Of, Place_Inside_Botton_Of, Place_Before, or
 Place_After. All the children would also be put back as well and as
 long as the Ada objects used to create them are still around you
 can access those elements if they are in the DOM or not.

But this is really good to know

Thank you.

[Gnoga-list] how to empty a table

[Björn Lundin]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1


Having a table

  Result_Table  : Gnoga.Gui.Element.Table.Table_Type;

How do I empty it?
I've populated it with data from a recordset,
and now I wan't to rerun the query,
and then fill the same table with a new recordset.

But I do not want to add rows to the table,
I want to empty/reset/clear it before re-populating.

with

   type Default_View_Type is new Gnoga.Gui.View.View_Type with record
  Result_Table  : Gnoga.Gui.Element.Table.Table_Type;
  Run_Query : Gnoga.Gui.Element.Common.Button_Type;
   end record;


I tried

   procedure On_Click_Run_Query (Object : in out
Gnoga.Gui.Base.Base_Type'Class) is
  View : Bot_Gui.View.Default_View_Access :=
   Bot_Gui.View.Default_View_Access (Object.Parent);
   begin
  View.Result_Table.Remove;
  View.Result_Table.Add_Caption(Today's result);
.

and it does remove it, but next recordset
is not visible. It looks like it is still
valid in ada, but removed from the DOM.

I then tried
  View.Result_Table.Remove;
  View.Result_Table.Create (View);

but that gives me
Dispatch Error
GNOGA.GUI.BASE.OBJECT_ALREADY_CREATED - gnoga-gui-base.adb:267

 Very strange error indeed, git annotate shows that even the
 current version pre-dates the AWS-GPL version:
 
 79a38bab(Pascal Obry2014-02-01 18:53:18 +0100
 132) procedure Close 79a38bab(Pascal Obry2014-02-01

 135) Error   : Error_Type := Normal_Closure); 79a38bab
 (Pascal Obry2014-02-01 18:53:18 +0100   136) --  Send a

I've got
aws-3.1.0w-20130907-src.tgz

and it does not contain Close.
I'll upgrade

This I think was a wavefront I got from ACT
regarding something else, I think smtp and tls
