Working with files

How to access the path of the current project

This gets the directory where the current IES-VE project is stored on the local computer. This is done using the path propoerty of the VEProject class. If no path exists, the built-in Python GUI package Tkinter is used to display an error message box.

import iesve
import os
from tkinter import Tk, messagebox
currentproject = iesve.VEProject.get_current_project()
dir_currentproject = currentproject.path
if dir_currentproject == '':  # if no path exists, show an error message box then exit.
   root = Tk()
   root.withdraw()
   messagebox.showinfo('User action required', 'Please save the IES-VE project.', parent = root)
   root.destroy()
   quit()

currentproject is an instance of the VEProject class.
dir_currentproject is a string of the full path to the IES-VE project as saved on the local computer.

How to ask the user to choose a IES-VE result file

This opens a dialog box for the user to select an IES-VE results file (an .aps file). The built-in Python GUI package Tkinter is used to display an error message box if no file is selected or the file selected is not in the current IES-VE project.

import iesve
from tkinter import Tk, messagebox
from tkinter.filedialog import askopenfilename
import os
currentproject = iesve.VEProject.get_current_project()
dir_currentproject = currentproject.path
dir_vista = os.path.join(dir_currentproject, 'vista')
root = Tk()
root.withdraw()
fp_in = askopenfilename(title = 'Select IES results file', parent = root, initialdir = dir_vista, filetypes = [("APS files","*.aps")])
root.destroy()
# - Exit if filepath is empty string
if fp_in == '':
   root = Tk()
   root.withdraw()
   messagebox.showinfo('User input needed', 'Please select a .aps results file.', parent = root)
   root.destroy()
   quit()
# - Exit if filepath is not in project filepath
elif not dir_currentproject in fp_in:
   root = Tk()
   root.withdraw()
   messagebox.showinfo('User input needed', 'Please select a .aps results file in the current IES project.', parent = root)
   root.destroy()
   quit()

currentproject is an instance of the VEProject class.
dir_currentproject is a string of the full path to the IES-VE project as saved on the local computer.
dir_vista is a string of the full path to the vista folder of the IES-VE project as saved on the local computer. This is where the .aps results files are stored.
fp_in is a string of the full path to the IES-VE results file as chosen by the user.
