currentRowChanged Signal slow when calling some functions

Hi, i'm trying to code a frontend, i have a game list, when currentRowChanged singal is activated, i do some screenshots/boxart/ searchs with QDirIterator, but this makes QListView very slow to change row.
Is there any way to speed it up?
if i keep the down key pressed, the selection freezes, until i release the key.
Maybe QDirIterator + file by file search is not a good way to do this...
Hope anybody can help me a little, thanks and sorry for bothering you

You can delay the search some small amount of time (e.g. 100ms) using a timer. This way only when the user stops changing the current item, the search will begin.
