gtk:text-view-accepts-tab (object)

object -- a gtk:text-view widget
accepts -- true if pressing the Tab key should insert a tab character, false, if pressing the Tab key should move the keyboard focus

The accessor for the accepts-tab slot of the gtk:text-view class gets or sets the behavior of the text view when the Tab key is pressed.

If the accepts argument is true, a tab character is inserted. If the accepts argument is false the keyboard focus is moved to the next widget in the focus chain.
