how to update Label "e1" ?

[thoschu96]

I wrote a code and wanna update the PATHNAME for E1.
The Print show's that the Pathname is updating,
but the LabelField is not updating.
What i am doing wrong ?

One way is to create a StringVar and assign it to the entry field textvariable option. Use the StringVar object's method set to assign a value. Use a lambda in the browse button command assignment so you can pass the StringVar as an argument for reassignment. You should not need a global variable.
