Repository: kde-workspace


Description
-------

I'm reopening this review request as I have updated this Window Switcher for Plasma 5.1 and would like to get another review to check if there are any suggestions or issues regarding the port to the new API.

Secondly I would like to ask again to have this Window Switcher Layout included in the KWin repository. I would prefer it if users could obtain this layout from their trusted distributors and did not have to rely on an unverifyable third party download to obtain this plugin. 

As suggested in the original review I've put this up on kde-look and recieved some positive feedback. But I really feel that it is rotting away there and that KDE-Look is not a good place to distribute executable plugins.

IMHO the approach of this Window Switcher is different enough from the others included in KWin to be a useful addition to the fold. Especially as this behavior is already familiar to KDE users from some versions < 4.6

It should also be close enough to the other layouts like thumbnails to keep maintenance very similar (I've mostly looked at the changes made to thumbnails to adapt this for Plasma 5)


Original description:

This Layout tries to mimic some of the old KDE 4.6 tabbox behavior and layout, it scales the thumbnails shown in the tabbox to avoid scrolling.
There are also three different states in this layout depending on the size of the scaled thumbnails to provide appropriate information even when there are many opened windows.

States:
1. Thumbnails are larger then 200px: Show the Title and the Icon of the Window directly below the thumbnail.
2. Thumbnails are between 200px and 64px: Thumbnails are shown together with the icon but only the title of the currently selected window is shown.
3. Thumbnails would be smaller then 64px: Only the Icons of the windows are shown and the title of the currently selected window (like big icons)
If the Thumbnails would be smaller then 32px the tabbox starts to scroll in the Icon Only state.

Size of the thumbnails depends on the screen size and the number of opened windows.
