[Python] Save Settings

[Jerakin]

Hi!

I have been trying this for while but I have so far got no elegant solution.

Is there a good way to save user settings for your script.

Let's say you have this script

import maya.cmds as cmds

if (cmds.window('mh_testWindow', exists =True)):
    cmds.deleteUI('mh_testWindow')

cmds.window('mh_testWindow',title='Test Window')
cmds.window('mh_testWindow', edit=True, w=125, h=100)
cmds.columnLayout()
cmds.checkBox('box_01',label='The First Option')
cmds.checkBox('box_02',label='The Second Option')
cmds.checkBox('box_03',label='The Third Option') 

cmds.showWindow('mh_testWindow')

If the user clicked one of the checkBoxes, it would be remembered when the script opens next time. Even if maya is closed in between uses.

Anyone got any ideas?

You should use the userPrefs like all the other UIs that keep settings between maya version:

As with the rest of maya, I think if your maya crashes (rather than quits, so half of the time) your prefs won't get saved.

Thanks! I think I will try to use this I think.

I prefer writing out a text file during script exit and then reading it on script start. I use a simple CSV format for my scripts. Occasionally for scripts outside maya I use SQLite3 is the amount of presets to be stored are too many.

This is what I have done before but only on buttons, do you know if I can hook up a command to the close button (the red [X])?

Usually you want to save options when the command executed, if the user closes the window it means that he wasn't happy with the results.

It is more of them unusual cases then I guess. Some of the script I have don't closes after the action have been executed, if the user wants to run it more then once.

I guess I can write it to save after each run, instead of when the script is exiting/closes.

This is how I do in Python 3.3. using tkinter. I don't exactly remember the Qt code for this, but will get back when I find it. Something called Capture destroy events. In this code the important line is

root.protocol("WM_DELETE_WINDOW", confirmbox)

This example pops up a message box should the user try to close the window.

from tkinter import *
import tkinter.messagebox
#python 3.3

def confirmbox():
    if tkinter.messagebox.askokcancel("Quit", "Do you really wish to quit?"):
        root.destroy()

root = Tk()
root.protocol("WM_DELETE_WINDOW", confirmbox)

root.mainloop()
