Task Manager
The Task Manager provides a visual monitor of running applications and system processes, allowing users to forcefully terminate misbehaving apps and view system load.
Core Features
- Live listing of all active processes.
- PID (Process ID) inspection.
- Force termination of processes.
- Memory/Resource visualization (simulated).
Architecture & Dependencies
The UTaskManagerApp serves as the frontend controller for the underlying OS process manager.
UProcessManagerSubsystem: The Task Manager is effectively a visual wrapper over this subsystem. It queriesGetRunningProcesses()(which returns arrays ofFProcessRecord) and listens toOnProcessStartedandOnProcessTerminatedevents to refresh its UI dynamically.- Sending a "Kill" command from the UI calls
UProcessManagerSubsystem::TerminateProcess(PID), which cascadingly asks theUAppLauncherSubsystemto close the associated window.
