Its a bug, going to be fixed in 4.5.1. Its because I never set a 
QSizePolicy on the label. So if you don't set one on the KCM it goes

Yes, its ( Kcmmodule.comment ) the comment is meant to be 
more descriptive. I shall fix that

Someone posted on the blog about this, its a good point. I tried to use 
the whole of the frame so when maximized it looks as good as it does 
minimized. I am worried that it will all be left heavy. I was aiming for 
keeping the destination of the network interface separate as it can be 
expanded upon later. It also helps when you have two network cards in 
your PC on different subnets. I don't want to add a big lump of group 
text on the left without any kind of diagram model. This model shows the 
information all separate with some kind of flow.

also it took me ages to paint that arrow onto a QWidget. :)

True, I was looking to group all the information into boxes. Network 
interface box, destination box, etc so to separate the items. Kind of 
abstraction to the different elements.

Depends on how many network cards I suppose. I added filters because its 
also going to have bluetooth network cards,  gsm and the like, I was 
also worried about screen size.

Yes, I added the icon to change with the strength but it does not show 
very well. I shall add a strength label.
