Hello,


I noticed that in Wayland protocol, when I perform a copy operation in a program, the \
protocol performs some data operations through `SetSelection` function. But when I \
set `Qt::WindowDoesNotAcceptFocus` via Qt in this program and write data via \
`setText` operation in `QClipboard`, the function `updateSelection` in Wayland will \
not send the `setSelection` signal. I found that the following code is causing the \
signal not to be sent.


`*globalKeyboard.focus.surface-&gt;client() == dataDevice-&gt;client()`.


may i ask why this judgment is necessary, and if I want my app to write clipboard \
data without getting focus, is there an alternative way I can do it?


Interested to hear back.


Best Regards.
