Select Print Unit in Python

This software has been produced to work with Wasatch SoftRIP and the Wasatch XML Access Option. The XML Access option is an extra-cost add on to Wasatch SoftRIP.

Select Print Unit

The sample Python scripts for barcode pull all have the Print Unit set to "1" for simplicity. Various methods may be used to change that. If an interactive user prompt is wanted, this sample source code may help.

Source Code

# Sample code to interactively prompt user for a Print Unit
#
import tkinter as tk
from functools import partial

maxUnits = 4
printUnit = 0 # global to be reset by this GUI window

class SelectPrintUnit(tk.Frame):        # Class to create GUI interface for selecting print unit
    def __init__(self, parent, *args, **kwargs):    # Constructor function for GUI widget
        tk.Frame.__init__(self, parent, args, *kwargs)
        self.parent = parent
        parent.title("Select a Print Unit") # Define GUI title bar
        parent.geometry('+300+200') # position  GUI in a predictable place
        parent.minsize(400, 100) # Set minimum width and height of GUI
        for i in range(0, maxUnits):
            s = "Print Unit " + str(i+1)
            tk.Button(parent, text=s, command=partial(self.click, i)).pack(fill=tk.X)

def click(self, number):  # Function to return print unit value on button press event
        self.parent.destroy()
        global printUnit
        printUnit = number + 1

#
#   That's it - the following lines are just a demo.
#
while True: # just loop forwever for this demo
    root = tk.Tk()
    SelectPrintUnit(root).pack(side="top", fill="both", expand=True) # Invoke GUI class object
    root.mainloop()
    print("printUnit is now set to " + str(printUnit))
