SirVer has proposed merging lp:~widelands-dev/widelands/keep_optr_in_ui into
lp:widelands.
Commit message:
A more principled fix to dangling object pointers in the UI.
The EditorGameBase class already tracks liveliness of MapObjects for us. So
let's make use of this instead of keeping the state updated through
Notifications.
Detailed changes:
- Make BuildingWindow use a OPtr<> to never try to access a building that was
deleted. Call die() whenver this happens.
- Remove BuildingNote::kDeleted. It no longer is necessary, since the UI has
another method to track livelyness of a building.
- Change BuildingWindow::init() to not be virtual, because it was never used as
a virtual function.
- Simplifications and type safety around child classes of BuildingWindow by
keeping another OPtr<> for the child classes where needed. Also made more
functions private.
Requested reviews:
Widelands Developers (widelands-dev)

Your team Widelands Developers is requested to review the proposed merge of
lp:~widelands-dev/widelands/keep_optr_in_ui into lp:widelands.
