[Qt-interest] Howto grab window from X11 display other than applications display

[Wilhelm]

Hi,

with QPixmap::grabWindow() i can grab the contents of windows on the
applications display, say localhost:0.0.

How can my application (connected to localhost:0.0) grab windows from
another display e.g. localhost:1.0 ?

I tried to use the code of QPixmap but with no luck due to the private
headers in Qt.

Any hints?
