Detailed Description

Changes a QObject property with undo support.

Warning

This command stores a raw reference (object_) to the QObject. The caller MUST ensure the QObject outlives this command on the undo stack. If the object may be destroyed by other commands (e.g., it is owned by a model that can remove/replace it), use a state-based command that captures the data by value instead — otherwise undo will dereference a dangling reference (use-after-free).
