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.<BR><BR>Like:<BR><BR>void ScreenShow::screenShot(QQuickItem
*item)<BR>{<BR> if (item && item->window())
{<BR> // Blocks for a short
moment<BR> QImage image =
item->window()->grabWindow();<BR>
// Could be done in later<BR>
image.save("/home/nemo/Pictures/iface.png")<BR>

<DIV>but it still block the UI（about 3<SPAN lang=en id=result_box
class=short_text><SPAN class=hps> seconds</SPAN></SPAN>） w<SPAN lang=en
id=result_box class=short_text><SPAN class=hps>hen the program starts (
</SPAN></SPAN>or after click the label“Hello Sailors”)</DIV>
<DIV>While, it seems that there is no such blocking when using the harbor
