# SimPy + Tkinter Boilerplate

![](./images/social_preview.png)

This boilerplate project demonstrates the use of **Tkinter** for real-time visualization of discrete event simulations with **SimPy**.

## Examples

The following code snippet shows the basic structure of the simulation program. The simulation itself is executed in a separate simulation thread, while the GUI uses the main thread.

```python

import threading

import tkinter

import simpy

import simpy.rt

# define the simulation ticks per second

ticks_per_second = 30

# define the total duration of the simulation run

duration = 10 * ticks_per_second

# create Tkinter common objects here

window = tkinter.Tk()

def run():

    env = simpy.rt.RealtimeEnvironment(factor=1/ticks_per_second, strict=False)

    # define SimPy events here

    # create SimPy resources here

    # attach SimPy processes here

    env.run(until=duration)

# run SimPy simulation event processing in simulation thread

thread = threading.Thread(target=run)

thread.start()

# run Tkinter interaction event processing and component rendering in main thread

window.mainloop()

```

## Screenshots

When executing the simulation program, you should see the following real-time visualization.

## Guides

### Prepare the development environment

Download and install the SimPy discrete event simulation library.

```

pip install simpy

```

### Run the simulation program

Execute the simulation program with your standard Python interpreter.

```

python ./sources/main.py

```
