Scroll at cursor position - lollo - Jan-30-2018

Hi guys,

I'm new on this forum.
I registered for despair :(

I have a (maybe little) problem with the Text widget.
When I paste some text from clipboard and the last line leave out of form view, the scroll bar (or text widget) doesn't move on cursor position.
I found this function:

IMPORTFILES_list.bind("<KeyPress>", gotocursor)

and the function:

def gotocursor(event):
IMPORTFILES_list.insert(END, "")
IMPORTFILES_list.see(END)

but every time that I press any key, the function want to go to the cursor.
I would like that this function will be recall only if I paste along text with ctrl + V.

Someone can hel me?

Many thanks

You could perhaps bind the Control-v event

from tkinter import *

def foo(event):
    print('foo() was called with', event)

root = Tk()
T = Text(root, height=10, width=30)
T.pack()
T.bind('<Control-v>', foo)

T.insert(END, "Just a text Widget\nwith 2 lines\n")
mainloop()

Hi Gribouillis,

wow, works!!!
Many thanks for your replay.
I don't knew that you can put "Control-v"...
It works, but it should do it when I release the keys...
Maybe with a delay?

Or maybe by setting a variable and catching the release of the v key. See if this works

from tkinter import *

CVPRESS = False
def foo(event):
    global CVPRESS
    CVPRESS = True
def bar(event):
    global CVPRESS
    if not CVPRESS:
        return
    CVPRESS = False
    print('bar() was called')
root = Tk()
T = Text(root, height=10, width=30)
T.pack()
T.bind('<Control-v>', foo)
T.bind('<KeyRelease-v>', bar)

T.insert(END, "Just a text Widget\nwith 2 lines\n")
mainloop()
