Python GUI Sample program

The Python GUI sample programs included in this device driver use Tkinter (Tk interface) as a graphical user interface library.

The files that contain the main function for these GUI sample programs are provided with a ".pyw" extension.
When you double-click ".pyw" file in the target folder with File Explorer to start the sample program. (Example: SampleApp.pyw)

▪ Using Events

All Python GUI sample programs use callback functions to handle event notifications.

Even with the same project name, the way to handle event notifications are different for other development language's sample programs. (VB. NET, VC#, VC++, etc.)
The traditional message notification handling of event notifications has been replaced by callback functions.

▪ Python for Windows

Python for Windows provides python.exe and pythonw.exe.

python.exe uses with a console (command prompt or terminal).
You can execute the program when you specify a file with the extension ".py" on the console.
Ideal for CUI programs. Also useful for files that contain only subroutine functions.

pythonw.exe uses without a console.
You can execute the program when you specify a file with a ".pyw" extension, such as in File Explorer.
Ideal for GUI programs. The ".pyw" extension is typically associated with pythonw.exe.
