Re: paste client clipboard selection to guest

[Alex Roithman <kaperang07@xxxxxxxxx>]

i checked some clipboard actions in one same virtual machine. The different in usage clipboards in the virt-viewer (Remote Viewer) app and the my app is that:

[In virtual machine console]:

$ kill -9 </usr/bin/spice-vdagent>
$ /usr/bin/spice-vdagent -d -x

......
spice-vdagent[.....]: 0x24f1010 received clipboard data, arg1: 0, arg2: 1, size 26
spice-vdagent[.....]: clipboard: received clipboard data without an outstanding selection request, ignoring
......
screenshot of case

As i think:
arg1=0 (arg in code VD_AGENT_CLIPBOARD_SELECTION_CLIPBOARD)

arg2=1 (arg in code VD_AGENT_CLIPBOARD_UTF8_TEXT)

size=26 (size of received text)

It is accords with code and matches the usage case, but spice-vdagent dropped received data.

Then i have the question: how to emit this request (i think this “main-clipboard-selection-request”)?

To: Christophe Fergeau <cfergeau@xxxxxxxxxx>

Yes, in remote-viewer and virt-manager copy/paste works.

I try to implement spice viewer using spice-client-glib-2.0.

Video, sound, send files, copy selections from guest to host -- works.
One problem: paste from host clipboard to guest.

It is a code place: .../vm_viewer/qspice_widgets/qspice-main-channel.cpp#L306 .

How i implement it:

just read data from QClipboard, then set appropriate data type
and call spice_main_clipboard_selection_notify(...) with this data
by clipboardSelectionNotify() method.

I check when the guest clipboard was released, but not works too.

Can you be more specific about what you are doing?
Do you have an application based on spice-gtk or spice-glib? Have you
checked how spicy (for example) handles copy and paste? Or are you
trying to do something special which spicy/remote-viewer are not doing?

Also, I assume you checked that with the applications mentioned above,
copy and paste works? (ie the agent is running in the guest, and working
as expected, it's only a problem with your code?)
