Hi, all<br><br>I want to implement the feature: file drag-and-drop between the host and<br>guest. But i dont know whether someone is working on it, if this feature<br>has not been implemented, i want to implement it in my spare time.<br><br>Any suggestion is welcome.<br><br>My idea is:<br><br>0) Now i only consider file drag-n-drog from host to linux guest.<br><br>1) On QEMU side. virtserialport and spicevmc are used as communication<br>channel, e.g.<br>$ qemu -chardev spicevmc,id=charchannel0,name=filetrans -device<br>virtserialport,chardev=charchannel0,name=filetransfer<br><br>Because Hans has made spicevmc generic channel(commit c03038), we dont<br>need to change any code in QEMU for using spicevmc as backend of<br>virtualserialport.<br><br>2) On guest side. Use a simple daemon, or hack spice-agent to read/write<br>virtserialport mentioned above for receiving/sending file content.<br><br>Since we just want to receive/send file, the message protocol is
simple.<br><br>3) On spice server side. Attach a new SpiceCharDevice for communication<br>with spice client and guset, rather than creating a new channel.<br>e.g.<br>static int spice_server_char_device_add_interface(SpiceServer *s,<br> SpiceBaseInstance *sin)<br>{<br> // [..snip..]<br> if (strcmp(char_device->subtype, SUBTYPE_FILETRANSFER) == 0) {<br> dev_state = attach_to_filetransfer(char_device);<br> }<br> // [..snip..]<br>}<br><br>The reason why i dont create a new channel is: a new channel wont<br>register util guest open the virtserialport. in this case, if spice client<br>connects to spice server, it can not receive any information about<br>the channel we created and will not create client channel for it.<br><br>4) On
spice client. Spice client receives the message server passed to<br>it, handles the signal related "drag-n-drog", provide the callback for<br>handling it.<br><br><br>hans, Marc-André, any suggestion?<br><br>-- <br>Best Regards,<br><br>Dunrong Huang<br>_______________________________________________<br>Spice-devel mailing list<br><a ymailto="mailto:Spice-devel@lists.freedesktop.org" href="mailto:Spice-devel@lists.freedesktop.org">Spice-devel@lists.freedesktop.org</a><br>http://lists.freedesktop.org/mailman/listinfo/spice-devel<br><br><br> </div> </div> </div></body></html>
