Something that perhaps has something to do with this. I get this error most
times when opening a new ImageView window:
'ErrorException("getgc: Canvas is not drawable")'
So I make a while loop with "try" for the image view, until it appears. The
code is like this:
appeared = false
while !appeared
try
canv, imageslice = ImageView.view(p_img)
timedwait(es_falso, 0.1; pollint=0.1)
appeared = true
catch err
println(err)
end
end
