+
+
+After click on list `<<ListboxSelect>>` executes function which gets data from list (as single string) 
+splits it to three elements using `slicing` and `strip()`, and puts elements in three `Entries`
+
+Program use 
+
+- `"{:10s}|{:15s}|{:10s}"` to format columns in text, 
+- monospaced font `font=('monospace', 10)` to correctly display columns on list.
