To force a keystroke you can use this:
void=win:IDSendMessage(MCx,WM_KEYDOWN,#22,0)
for example to force a keydown.
The only way to make this cross platform is to use a library that allows
windows programs to run under Linux. The reason is the GdiPlus lib is
made for Windows. There is a lib called "Wine" that allows Windows
programs to run under Linux, but i've never tried it. Perhaps you can
ask some others who have some experiance with it about this.
BTW i had a tiny problem with the 'count' in that if there are any
files that are not picture files in the directory they tend to mess
up the count, so that pic #1 might come out pic #2 if you forward to
the end of the directory and then back up to the beginning.
I tried this with only 8 pictures in a directory and one ex.err file
that got there by accident when the viewer first crashed without the
include file i talked about. What happens is when i forward to the
last pic (and maybe hit forward another time not knowing it's the
last pic) then go backward trying to get to the first pic, the pic
count gets all messed up because that one extra file (ex.err) messes
up the 'count' variable. In other words, it looks like maybe managing
the 'count' variable to keep track of pics (which by the way is also
a good idea) needs to be looked at again (with at least one pic that
is not a picture in the same directory as some pictures you are viewing).
In my original viewer i only kept track of files by index, even if
they were not pics, so it counted everything in the directory. This
was not as good as having 'count', but it was easier to implement :)
Take care,
Al
And, good luck with your Euphoria programming!
