[gtkada] Displaying an application output

[Michael Gonzalez]

Hello:

I would like to invoke from a GtkAda application another standalone 
application and show its standard output in a text window, as  it 
executes. I have seen this done in gvd, for example. Any clues on how to 
do it portably?

Best regards,

Michael Gonzalez.
