This is not needed. Since all animations are created as children of the ToolsAreaManager, they should be deleted automatically when this one is destroyed.
This way you can simply remove the class destructor altogether and rely on the default one (from QObject).

As far as I have followed the code you need an "unregisterWidget" for when widgets are unpolished and to remove windows from the map.
You also need a connection to the destroyed signal to cleanup the map when a widget is deleted, otherwise you will keep accumulating an ever growing map of dangling pointers.

you can break here once one widget is found. no need to loop over the remaining widgets.
alternatively you can use std::any_of or (better) std::none_of

This seems to make the window content move vertically when the window loses focus

That's odd—the margin shouldn't be shifting based off of window status. Will investigate.

I believe this is due to how it determines "should draw tools area" conflicting with your colourscheme.
When active, the window and the titlebar colours are different, thus causing the tools are to be drawn. When inactive, the window and the titlebar colours are the same, causing the tools area to not be drawn.

That's still needs fixing though. You cannot have things floating around depending on which color scheme is used. right ?
There are many color schemes of all types in the wild. The widget style must work for all.

This is intentional—if a window's titlebar and content colours are the same, the window is drawn as a homogeneous window instead of a window with a tools area.

I was not refering to the rendering of the separator, but rather to the fact that the widgets margin change between active and inactive. This should not happen (disregarding the color scheme).
All in all, whether you need to draw the separator or not you need to add the margin always (or follow David's suggestion)
Unless I misunderstood the actual issue reported by Nathan of course.

Maybe the decision whether to do this could only be made based on the colors of the active state so it's consistent with the inactive one.
Also this happens because the separator line? Do we actually need it? Currently there is no separator between titlebar and window and/or between toolbar and other window content?

Did you check that this chunk of code (changing the contents margins of the QMainWindow) has any effect ? I had my doubt so I changed the margin to 100 instead of 1, added a printout to make sure that this line of code is called, then ran dolphin and
1/ the code is indeed called
2/ it changes nothing, on dolphin, okular, ...
if you can confirm, then just drop it.

(in fact, I don't understand the login in the first place: why would you need to add one pixel on top of everything in the QMainWindow ?)

This only triggers when the window has no items in the tools area—it's used in conjunction with line 878 of breezestyle.cpp in order to render a border at the top of the window.

When I run GDB on oxygen-demo5, sometimes it tells me that oxygen-demo5 crashes on this line. I'm not sure how to make it happen reliably, but it usually involves changing QStyles with the Style combobox or color schemes with the Color Scheme combobox.
