Hi all ,
i'm writing a really big(fat?) program ,
there's lots of function on this program ,
and i use a lot of widget / dialog box ...something like that ,
and i also add Qt::WA_DeleteOnClose ,
but seems like Qt will not release ram space back to system?
i've test to open all my function and close ,
at first my program run , it only take 1.7% of memory
after all the function open once , it take 2.2% ~ 2.3% of memory
and it keep in 2.2%~2.3% of memory usage , no matter the function opend twice or more times
Is there anyway to release Qt's memory back to system ?
thanks for any reply~
