Can't you just use the GTK versions? Qt implements the IDE but there's
nothing in the language tied to this. For example, I can do this in my
jconsole running under emacs, which knows nothing about any image libraries:
load '~addons/gui/gtk/gtk.ijs'
$picfls=. {."1 dir '*.jpg' NB. How many .JPGs in this dir?
170
3{.picfls NB. What are some of their names?
+------------------+----------------------+------------------------+
|1-charredmicro.jpg|130302125400-large.jpg|4-3-2-1-anotherlinkb.jpg|
+------------------+----------------------+------------------------+
$img=. readimg_jgtk_ '1-charredmicro.jpg' NB. What is size of this
image?
466 500
5 5{.img NB.
