The python version is using dbus, but the idea is the same:

self.bus.add_signal_receiver(self.unlock, path='/com/nokia/mce/signal', dbus_interface='com.nokia.mce.signal', signal_name='tklock_mode_ind')

You can turn off the autolock by changing the value of GConf key /system/osso/dsm/locks/devicelock_autolock_enabled

Tried it and at least this doesn't open it, when it's already locked:

Code:

gconftool -s -t bool /system/osso/dsm/locks/devicelock_autolock_enabled false

So if you you lock your device when you are at work for example and then you go home, it will ask the password when you open it.

I have been testing the dbus devlock_close call more.

If I lock the device with dbus like this:

Code:

dbus-send --system --type=method_call --dest=com.nokia.system_ui /com/nokia/system_ui/request com.nokia.system_ui.request.devlock_open string:"com.nokia.mce" string:"/com/nokia/mce/request" string:"com.nokia.mce.request" string:"devlock_callback" uint32:'3'

And then unlock it like this:

Code:

dbus-send --system --type=method_call --dest=com.nokia.system_ui /com/nokia/system_ui/request com.nokia.system_ui.request.devlock_close string:"com.nokia.mce" string:"/com/nokia/mce/request" string:"com.nokia.mce.request" string:"devlock_callback" uint32:'0'

Everything works great, but when I lock it with the power button menu and then use dbus to unlock, the power button menu stops working, until I use dbus to lock it again and then open it with password. Could someone confirm this?
