Hi, thanks for the screenshots. See comments to individual options below. On 06/16/2015 11:48 PM, Ladislav Slezak wrote:
Hi all,
I'm implementing a new online migration dialog for selecting the migration target. (This tool is will be available only for SLE12, for openSUSE it does not make sense as the product cannot be registered in the SUSE Customer Center (SCC).)
The new online migration tool will find all installed products in the system and ask the registration server for possible migrations to new service pack(s).
The response from the server will contain all allowed combinations to all available products and extensions. E.g. [ SLES-12-SP1 + Extension-Foo-SP1, SLES-12-SP1 + Extension-Foo-GA (if the GA version is supported on SLES SP1), ...] That means there could be potentially quite a lot of possible migration targets.
User can select just one migration target in the dialog which will be applied to the system.
The problem is how to design the UI. Here are some my ideas with screenshots (mockups). The screenshots were taken in the minimal supported resolution (800x600 in GUI, 80x25 chars in text mode) to see the minimal available space for widgets.
RadioButtons ------------
Qt: http://paste.opensuse.org/3268571 ncurses: http://paste.opensuse.org/65912174
This was the initial design as the RadioButton is the usual widget used for selecting a single option from many possibilities.
+ (IMO) clear meaning for the users (one from many selection). - It's not possible to scroll the list if it is longer than the available space, in that case some RadioButtons will be missing. That's clearly visible in the ncurses screenshot, if there was one more installed product (or one more migration target) then the UI would break...
As it is shown, it looks rather ugly to me. You could fix that via some frames, but still, looks somehow weird. Although I don't see the problem with too many options, each option can consist too many products (imagine system with 3 or more extensions installed). With NCurses, it is not obvious which line belongs to which radio button - you would need to add some spacing, with already limited space...
SelectionBox (with multi-line values) ------------------------------------
Qt: http://paste.opensuse.org/34590676 ncurses: http://paste.opensuse.org/65761791
+ Scrollable list, no problem with many migration targets. - There is no separator in the list, it's not clear how many migrations are there and what each migration includes unless you click on some line. - Ncurses UI does not support multi-line values (only the first line is displayed).
I like the way you described the problems :-)
SelectionBox (with single line values) + RichText (with details) ----------------------------------------------------------------
Qt: http://paste.opensuse.org/45144130 ncurses: http://paste.opensuse.org/56893356
Similar to the previous one, but there are short product names used on a single line in the SelectionBox. Additionally there is a RichText with details of the selected migration target. (The screenshot shows just the full product names, but we could simply add more details like the list of the migration repositories, the repository URLs, whatever...)
+ Both widgets are scrollable. + Works in both Qt and Ncurses UI properly. - More complicated for users, not obvious how the dialog works and what is expected from the user.
I don't find that any complicated - you have one list, where you select, and a widget which displays more details. I like this option most. Jiri
So far the last solution looks the best for me. What do you think about it? Any suggestions or ideas how to improve it? Or even a completely different design?
