Dispatcher

Dispatcher is a simple scheduler test application developed using the Qt framework. The application simulates basic process management functionalities, including creating, switching, blocking, unblocking, and deleting processes. It provides a graphical user interface to manage and visualize these processes.

Features

• Create New Process: Add new processes to the scheduler.
• Trigger Switch: Switch the currently running process to the ready state.
• Block Process: Block a specified process by its ID.
• Un-Block Process: Unblock a specified process by its ID.
• Delete Process: Delete a specified process by its ID.
• Process Visualization: Display processes in different states (Running, Ready, Blocked) using tables and lists.
