Tux Paint

Don't tablets generally require calibration?  Maybe I'm wrong but perhaps
the tablet isn't configured for 640x480 or 800x600 or whatever resolution
the full-screen mode runs as?

I'll ask.  Someone back in July (w/ 0.9.14) reported problems with
Tux Paint in fullscreen mode under Windows XP using a drawing tablet
(e.g., an external drawing device; not a touchscreen like I believe the
recent report is talking about).

They said switching to Windowed mode solved the problem for them. :^/

;)

Hi,

using the 'windib' driver might help as well. In fullscreen mode using
the directx driver it tries to use directinput which causes a few other
problems as well (no mouse acceleration),

cheers,
John.

Did this build use DirectX or WinDib? If it was DirectX, it's probably 
worth seeing if Windib fixes it (and we'll add it to the list of 
interesting things that are now broken in our directinput code...).

DirectX.  Having people switch to WinDib[*] seems to be fixing it.

I'm having problems with spanish accented characters in Tux Paint Text tool in 
0.9.15-2 under Windows.
Accenter characters simply don't appear.

After I installed 0.9.15-2 I've had a hard time finding the saved images.
Only now that I went to the web page I've learned that they are in a new 
location now (I know, my fault for not reading the documentation) :)

But, what motivates this message is that I find the new location not suitable 
for user created documents.
"C:\Documents and Settings\(user name)\Application Data\TuxPaint\whatever"
could be used for saving configuration data, but it's not a place intended for 
direct user access and so it's a strange place for TuxPaint user images to be 
saved.

I think the best place for saving user images would be:
C:\Documents and Settings\(user name)\My Documents\TuxPaint\
or something like that, since it's easily accessible for users to backup the 
images, do mainteinance, etc.

Well, just my opinion...
Thanks for listening.  :)

Gabriel

Hi Gabriel,

I've had a look at this and it seems to be an SDL (on Windows) problem.
Even if it can't be solved for the general case, it's pretty poor that
it doesn't handle Spanish! 

We're in the fortunate postion of being able to ship a custom version of
SDL, if neccessary, so it can probably be fixed - I'll look into it ....

best regards,
John Popplewell.

I think the docs were out of date for a while there (thanks bill!).

Hi Gabriel,

I considered putting the images somewhere like that when I moved them
from the application directory (what about My Pictures/TuxPaint?) but
currently the images, configuration and temporary files are "mixed up"
in the same directory.

So I punted and just made sure they went somewhere per-user that Tux
Paint was guaranteed to be able to write to.

Having separately configurable image, config and temp directories would
allow this structure to be rearranged so that the images are at the
top-level.

One work-round would be for Tux Paint to (optionally) make a Windows-style
shortcut to the 
"C:/Documents and Settings/(user name)/Application Data/TuxPaint/saved/"
directory, in "My Documents" when the user starts it.

I don't know if this would help with backup procedures though,

best regards,
John Popplewell.

Hi Gabriel.  This is the direct fault of Tux Paint, but I'm not 100% sure
how well the underlying SDL library can support this.  I sadly haven't
looked into it.

I wonder, I can set up a "dead keys" system on my KDE desktop at home,
so that if I type ['] then [a], it will show "=E1", for example.  However=
,
I'm not sure if SDL would pick that up.

I suppose I should test it. :)


The whole issue of "I can't enter characters in [my favorite language]"
is a known one, and has lived in the TODO list in the past, and is now
listed in the Bug Tracker at SourceForge:

Any help would be great. :^)

Well, speak for yourself.  (Well, Windows, Mac OS X, and Klik :^) )

Hi Bill,

I did that on Windows and tried some of the SDL test programs - they
don't work properly either.

Looking at the SDL documentation Wiki, I can't find a definitive
statement about the 'Uint16 unicode;' field in SDL_keysym. Is it correct
to assume that it is UTF8?

I'm looking at a bodge that would cause 'SDL.dll' to depend on
'libiconv-2.dll' and use it to convert from UTF-16 (NT/2K/XP) or some
horrible 8-bit (code-page) character (Win9x/ME) into UTF-8.

I would probably dump the SDL 'directx' driver at the same time as it
seems to be part of the problem.


I didn't realise that the X11 SDL backend has the same problem. I just
tried on KDE and whilst the terminal (and most of everything else) works
ok, Tux Paint and the SDL 'checkkeys' program don't.

Oh, well...

SDL_inputmethod looks like a good solution for CJK languages, but surely
SDL would benfit from working composition for e.g. Spanish?

I'll cast my eye over it (it's probably horrible, isn't it :-),

cheers,
John.
