Subject: [PATCH 12/20] QQuickItemAnimation: close potential memory leak
|
|
|
966857 |
|
|
|
966857 |
Fix static analyzer warning bff6cb4333f531d5a72f7bf6dc1485f6.

If ownership of viaData is not passed to the viaAction, then the object
|
|
|
966857 |
might be leaked. Use std::unique_ptr to make ownership transfer explicit
|
|
|
966857 |
and implicitly delete unowned objects.
