Hi all,
I want to know is my solution is 'clean'.
I need good gui response if cpu is very busy. in this example cpu is
compute my photo images on to low res.
in next step i need compute md5 sums for each image etc.
Is it good solution write all gui class as Thread or better way is
write only critical cpu code into thread like md5 checksums, resizing
etc.
in this example i want use slider if cpu is computing, which is work.
thanks for your comments.
