Printing with GtkADA

Printing with GtkADA

[ldries46]

I am trying to create ADA programs in windows XP. Therefore I am using 
GTKAda. I cannot find any reference to how to print the info in a TextView 
window. I am using the text view window for convienience and have found 
various possibilities but not how to print or even how to sned something to 
a windows printer.
Can anyone tell me how that must be done

Gtk's Gtk_Text_View uses the MVC model. That means you have to change the
model in order to make the viewer to show anything. In short you should
modify the text buffer of the widget in order to make Text_View to show it.
For example, you could use Set_Text. See for Gtk_Text_Buffer

http://www.adacore.com/wp-content/files/auto_update/gtkada-docs/gtkada_rm/gtkada_rm/gtk-text_buffer.html

(the function Get_Buffer returns the current text buffer of the widget)

It 's clear to me how to get my text buffer back. Now I want to send it to 
the printer within windows, so I want to see for instance the windows 
printer dialog to choose my printer (or PDF creator) or a GTK alternative 
for it. The last would be better if I want to design my program in a Windows 
enviroment and run it also in a Linux enviroment for instance.

I see it is not GtkTextView, it is printing what you need. GTK+ has
printing API[*]. But AFAIK it is not yet supported in GtkAda 2.10.

You should do these bindings by yourself (which should be not that
difficult) or else wait for some next version of GtkAda. If you are a
paying AdaCore customer, you might ask them to do it for you.
(AdaCore maintains GtkAda)
