I have a text field, and i want to get the value out of it when the user  
presses Return or tabs to another field. Currently i’m doing it like  
this:

name\_field = TkEntry.new(root)  
var = TkVariable.new(“f”)  
name\_field.textvariable(name\_var)  
name\_field.pack()

name\_field.bind(“Key-Return”) { name\_field\_value = name\_var.value }  
name\_field.bind(“FocusOut”) { name\_field\_value = name\_var.value }

It seems like there should be a way to combine these, like

name\_field.bind(“Key-Return” || “FocusOut”) #doesn’t work  
name\_field.bind(“Key-Return”, “FocusOut”) #doesn’t work either

But these doesn’t work. Can anyone tell me how to do this please?

## Please use TkVirtualEvent object.

virt\_ev = TkVirtualEvent.new(“Key-Return”, “FocusOut”)

# or use TkVirtualEvent#add(seq, …) / TkVirtualEvent#delete(seq, …)

name\_field.bind(virt\_ev) { name\_field\_value = name\_var.value }
