Hi,
If you want to capture something on your application side, you can grab whole
window through QQuickItem. This part is blocking but you can do capture
manipulations in async manner quite simple by using QFutureWatcher.
Like:
void ScreenShow::screenShot(QQuickItem *item)
{
if (item && item->window()) {
// Blocks for a short moment
QImage image = item->window()->grabWindow();
// Could be done in later
image.save("/home/nemo/Pictures/iface.png")
}
}

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