Method: RubyCurses::TextView#paint

Defined in:

lib/rbcurse/core/widgets/rtextview.rb

#paint ⇒ Object

NOTE: earlier print_border was called only once in constructor, but when + a window is resized, and destroyed, then this was never called again, so the + border would not be seen in splitpane unless the width coincided exactly with + what is calculated in divider_location.
