# To subscribers of the xforms list from thorsten@flaz3.nt.fh-koeln.de :

hy,

now some bugs for x-mas ;-)

1. fl_show_fselector: using and holding arrow-down-key in file-window results in
a. mooving the yellow-selector down (just as expected) but also
b. suddenly selecting a file. (not so nice :-( ) !!!
'works' in fbrowse DEMO
2. flimage/canvas: i use a canvas in the form for displaying images.
once an image gets displayed, i change the color of some pixels
(image->red[a][b] = 255). to get the changes displayed, i call image->display.
ups! nothing happens :-((
figured out, saving the image before calling image->display is the right routine
to get the changes displayed!
(<G> hmmm, what about using this one for displaying.....)
o.k. the reason is that saving calls something like:
CanvasIntercept Event(12,..,..),
that image->display doesn't.
( i also tried: fl_redraw_object(canvas), flimage_display,
fl_update_display, XFlush :-(()

anny comments / workarounds / explanations ???!!!
system env: i586-linux-glib2 & powerpc-linux-glib2, icewm, forms 0.89A
