RE: [LINUX5250] dynamic fonts change.

["Marc-Antoine Ruel" <maruel@xxxxxxxxxxxxxxx>]

My ActiveX version is working almost right with automatic font sizes. I'll try 
to see how to fix it in win32 version if I can. But I go on vacation next 
week-end.
By the way there is 2 way to fix it in win32:

- Create a big offscreen buffer (Like the desktop size instead of window size) 
and use StretchBlt() to draw it resized(smaller) in the window.

- Update the font on resize and use the new adjusted font.

Currently I use the 2nd method but I think the first is simpler to design, I 
just didn't though about it when I coded... :)

For unix version, I can't help.

Not really.  For the xt5250 version, you can try using the xterm's menu,
by doing a Ctrl-rightclick in the window. it should give you options like
"Unreadable, Tiny, Small, Medium, Large, Huge".   This isn't part of
tn5250, it's part of xterm, and I can't promise that the fonts are in
the sizes you're looking for... but it might be worth a shot.


> Just maximizing the window does not adjust the font size.

The Unix version of tn5250 does not have support for resizing the font to
match the window size.

The Windows version has support, but it does not work very well.

Here's the status:

   -- The Unix version is an ncurses program.   That means it's written
       for a plain-text terminal, like the "console mode."   When you ask
       it how big the window is, it tells you 80x25 or 132x28.  (i.e. the
       number of characters, not the number of pixels)   Since that's all
       we get, we can't calculate how big a font should be.   If you know
       how to get around this problem, please advise.

   -- The GTK version may not have this problem, but nobody is actively
       developing it.  Even so, I have no idea how to enumerate what the
       available fonts sizes are, so even if I wanted to add support for
       this, I have no idea how to do it.

   -- The Windows version... I've been working on this.  I have never
       worked extensively with fonts in Windows, and I've been unable to
       find any examples on the Internet for resizing to match the
       windows.  So, I've been experimenting with a few different
       solutions, but it's slow going, and I don't have a lot of time.

If someone has expertise in these areas, I'd sure love it if he could
contribute code to make these things work nicely!
