ada, curses and windows

ada, curses and windows

[Massimo M.]

i can't use windows in curses.
they don't work, i looked for examples, but i find only too complicated
examples. can you give me some easy examples in using windows in ada?

i used 

winInput:=New_Window(Line_Count(8),Column_Count(8),Line_Position(8),Column_Position(8));
box(winInput);
refresh(winInput);

but no windows appears...
if i use 
box(standard_window), the box appears.

thanks in advance

The behaviour you see is correct.  Curses does not draw have window
borders; you have to draw the borders yourself, e.g. with a "box".

That's what I remember from the two programs I wrote with curses back
in 1992 or so.

BTW, have you considered TextTools[1,2]? It is a library on top of
curses that draws the window borders for you, offers a widget set
(buttons, scroll bars etc.) and even supports the mouse!

thank you for the help!

i found the problem. it seems that the "REFRESH" has strange behavior.
if i put a refresh(winInput), the box or the string don't appear, but if i
remove the refresh, the box and the string appear.

i found the problem.
the refresh, referred to the entire screen, erase the windows.
a refresh(winInput) is required, but if windows are used, the
refresh(standard_window) can't be called.
