Could you please add qml tests to cover those use cases you mention (ie active focus when clicking on decoration and raise/restore when activation from spread)?

I believe we already have a test for the first one (focus when clicking decoration). We had similar problems in the past before. Should investigate why it passes now even though there's a bug there (maybe it tests only with touches and not with mouse clicks, don't know).

Oh, and it's worth making lp:~unity-team/unity8/mousePointer from silo 022 a prerequisite as it makes a lot of changes in this code.

Silence, and fixed (the "model.name" was even wrong), we do get the surface name already as a fallback for window.title

Here's a case where it breaks still:

* minimize it
* press alt+tab (spread will show, dash is selected)
* release alt+tab
expected: dash restores
actual: nothing happens
* now launch something else from the launcher

All issues hopefully fixed; found a new one: we should restore minimized apps to their previous state (not normal) respecting the maximized bits.

Please test again :)

Michael Zanetti (mzanetti) wrote on 2015-10-30:

Quite an improvement, yes! Still some small ones.

* minimize a maximized window, select it in the spread => expected: maximized, actual: restored. Same for closing a maximized one and reopening. Not sure how far we want to go with those in a single branch... this one improves things already a lot and there's still lots to do. So you decide when you want to give it a rest with this branch. We can start splitting things into multiple branches.

* managed to break alt+f4 again. I tried to log out and in again and break it again but didn't manage so far. Will keep on trying.

* During the above, I found a super weird one :D Minimize all windows, now ctrl+meta+arrow shouldn't do anything any more. Here's how: press and hold ctrl+meta and then press all 4 arrows dogether down two times in a row. It will restore a window :D Not that this would be a common thing to do, but it does indicate some focus issue when everything is minimized. Can you try to find out what's going on?

- ApplicationManager.requestFocusApplication(appId)
+ ApplicationManager.focusApplication(appId);

careful with that... can you explain the reason for this? The difference is that with "requestFocusApplication()" the shell can still execute logic like focus stealing revention (if we had that) or playing some focusing animations. If you change it to focusApplication() ApplicationManager will immediately move the item to index 0 and set it as focusedAppication. Not saying this is necessarily wrong, but just making sure you had a reason to change it.

the ctr+meta-arrows is really easy to reproduce tho... just minimize all whindows, press and hold ctrl and alt, then use your flat hand to press down all the arrow keys, twice in a row. It will restore some windows.

Just found another one: when you semi-maximize a window (left or right), it is placed below the panel, but the panel's height is not subtracted and so the window's bottom edge is outside the screen.

I think I found how to reproduce the lost alt+f4: Switch to another vt (e.g. the unity7 session) and back to unity8. Alt+F4 will be gone. Could be an issue with general input handling and not directly related to the branch... Please give it a quick look if it is to be fixed in here or not.

Can't reproduce at all :/ Nothing happens in this case
