[PyQt] PyKDE4 solid question

[Peter Liedler]

Hello there,

I try to work on a PyKDE4 application and have problems on finding
tutorials, specially for configuration dialogs and solid. 

Currently I try to determine the block device address of my cdrom, but
it always gives me the AttributeError: device.
In the solid documentation there is a device function in block that
returns the block device as a string. 
Please tell me where I am wrong. Here is my code sample:

	curDevice = Solid.Device.allDevices()
	for cdrom in curDevice:
	    if cdrom.isDeviceInterface (Solid.DeviceInterface.Block):
		drive = cdrom.asDeviceInterface (Solid.DeviceInterface.Block)
		print drive.device()

Thanks in advance

Peter
