[Kde-hardware-devel] KDE networkmanagement plasma applet and disconnect issue

[Gökçen Eraslan]

Hello,

Yesterday, I have spent all my day to fix disconnect issue of KNM. The issue 
is, when you disconnect using plasmoid, something automatically reconnects 
interface. In current Solid::Control::NetworkManager we have a 
DeactivateConnection method[1], and this method is used in KNM. But this 
method just deactivate the connection and then NM tries to reconnect to 
another connection which is set as autoconnect. 

The bug here is using DeactivateConnection method of NM[2], here is another 
guy mentioning about the same problem[3]. Solution is to call Disconnect 
method of the according interface instead[4], which is added in NM 0.8. 
Unfortunately this method does not exist in current Solid. 

Attached patch (created against KDe 4.5.5) tries to implement this method in 
Solid by updating solid/networkmanager-0.7/dbus/nm-deviceinterface.h file 
which is autogenerated using qdbusxml2cpp and adding method to:

* libs/solid/control/ifaces/networkinterface.*
* libs/solid/control/backends/fakenet/fakenetworkinterface.*
* solid/networkmanager-0.7/networkinterface.*
* solid/wicd/networkinterface.*

However when I try to call it using:

Solid::Control::NetworkInterface* iface = 
Solid::Control::NetworkManager::findNetworkInterface(deviceUni);

if (iface)
  iface->disconnect();


the method is not called. I put debug lines to every method I've implemented, 
but nothing is printed and connection is not disconnected.

Any ideas about that? I'm not familiar with solid, the patch may have 
mistakes.

Cheers.
