Navigating with the keyboard doesn;t update the info on the right panel. Clicking the section with the mouse works as expected. Reproducible: Always Steps to Reproduce: 1. go to Device Information->device viewer 2. expand hard disk drive(s) 3. use the keyboard to navigate available partitions (another issue, these are listed as "hard disk drive", not "partitions", they should be explicitely be marked as partitions) Actual Results: the info in the right panel stays the same Expected Results: i'd expect the same thing to happen as the mouse navigation
Still reproducible with in latest master branch.

Can you still reproduce this? For me this works just fine, albeit you need to hit the enter key to actually select an entry and update the right hand pane. Which is consistent with how the other treeviews in kinfocenter work though. In fact, all standard tree views work that way I'm sure.
I'm not the reporter, but this bug persists. Furthermore, we need to do double click on the partitions to update the right panel, what makes inconsistent with other sections that require single click like the ones under "USB devices".

Well, I can't reproduce. So please provide a step by step guide including all the keys you hit. As for the pane update on enter: USB Devices is different it does start out completely expanded as it only shows USB data that is fully available right away. If you do that with general device data you may be waking up a device (e.g. a disk) because that data is not necessarily loaded right away. In the interest of power saving I would not change that TBH.
(In reply to Harald Sitter from comment #5) > As for the pane update on enter: > USB Devices is different it does start out completely expanded Being expanded or not seems to be an aspect which can be treated separately of having to press the Enter key or not to update the panel on the right side. Browsing through the device information by just using cursor keys feels more easy to me. This would make this ticket a "wishlist" item, though.
Yeah, I don't dispute that it'd be more convenient. But we simply don't know the cost of a query through solid, in fact solid doesn't because of its backend nature. So, I maintain that not querying devices as you browse past is a matter of energy efficiency. Default standby times are ludicrously long, so if you happen to wake up sleeping hdd it'll take 20 or so minutes until it goes back to sleep again. It's more or less the same reason the left hand treeview for the modules doesn't update the module view right away. Loading a module could be very cheap or not, we do not know, so the conservative choice is not loading the module until the user confirms their choice.
Sounds like this is intentional, then.
