How to get SEditableTextBox widget`s value?

I just write like this:SNew(SEditableTextBox);,I know in QT,we can call a widget by name,but I don`t know how to get this widget from UI.
Any idea?

Make a varable in .h:

TSharedRef<SEditableTextBox> MyTextWidget;

And add insted of SNew use this:

SAssignNew(MyTextWidget,SEditableTextBox)

MyTextWidget will point to newly created widget

It worked,thanks a lot!!!
