Why do I get this 'tk' window?

[terrypin]

While working on my novice scripts I sometimes get this 'tk' window after an error. It usually seems to be when my script is trying to use an empty clipboard. But I don't seem able to close it without restarting PSP 8.

PSP8 did not have access to the ctypes library, so when we made the pasting script we had to find another way. The only way to do that was to use the TKinter library. Unfortunately, it's not the best solution we could have come up with but it was necessary to automate pasting text as a text object. It seems the library doesn't respond well to being called via RunScript.

Thanks, understood. (Well, sort of!)

I've just noticed that a few of the scripts I use (made with help here, probably from you, a year or two ago) have 'from Tkinter import Tk' at their start:

Code: Select all

from JascApp import *
from Tkinter import Tk

def ScriptProperties():
    return {
        'Author': u'Terry Pinnell',
        'Copyright': u'',
        'Description': u'',
        'Host': u'Paint Shop Pro',
        'Host Version': u'8.10'
        }

def Do(Environment):
    # EnableOptimizedScriptUndo
    App.Do( Environment, 'EnableOptimizedScriptUndo', {
           
            })

And at the end I see:

Code: Select all

           
def getText():
    r = Tk()
    text = r.selection_get(selection='CLIPBOARD')
    r.withdraw()
    r.update()
    r.destroy()
    return text

Cannot test right now, but could that have been added to deal with this issue?

Code: Select all

from Tkinter import Tk

#normal Script code here

def getText():
    r = Tk()
    text = r.selection_get(selection='CLIPBOARD')
    r.withdraw()
    r.update()
    r.destroy()
    return text

That is literally the paste text feature we came up with. Yes, that's the reason that the Tk window pops up. When a script runs getText() PSP will attempt to grab text from the clipboard using the tkinter GUI library that comes with PSP. It will then return the text copied to whatever function is using it. If the script you're running has no need of pasting in text, the script should not have these lines.

Thanks, understood. I plan to work on it again later today but I think those lines are indeed for su scripts that do indeed use text from the clipboard.
