[SailfishDevel] Please help me， how to get the screen capture without block UI

[itviewer]

Dear ,
attachment is all my code，and I have been tried many times
but it still block the UI（about 3 seconds）  when the program starts ( or after click  the label“Hello Sailors”)
While, it seems that there is no such blocking when using the harbor store app "screenshot".

Very grateful，thanks everybody。
