[virt-tools-list] [remote-viewer PATCH 1/3] remote-viewer: Connect dialog changed to window

Lukas Venhoda lvenhoda at redhat.com
Wed Jun 10 12:47:25 UTC 2015


Sometimes the connect dialog didn't get a parent.
It didn't make much sense for it to be a dialog.

Changed the connect dialog to a window.
Moved the dialog code to its own module.
Moved the UI definiton into an XML.

Changed response ID from ambiguous -1 and 0 to GTK_RESPONSE_ACCEPT
and GTK_RESPONSE_REJECT.

Address is now required to connect with enter, or connect button.
Also sets connect button to non-sensitive, if no text is in adress entry.

Focusing in entries will now unselect recent connection.
This fixes an issue, when selecting a recent connection, modifying
the adress entry, and then doubleclicking the selected connection,
remote-viewer would try to connect to the address in address entry
instead of the recent connection.
Doubleclicking teh recent connection will also set address before
activating, just to be sure.
