+=== Cutting, Copying and Pasting
+
+When you right-click a Gtk::TextView widget, you are presented with a pop-up menu containing multiple options, of which the tree we are interested in here are Cut, Copy, and Paste. These three options also have assigned to them a set of built-in accelerator keys Ctrl-X, Ctrl+C, and Ctrl-V respectively. In the next example program (cutcopypaste.rb) we will explore these three options:

+
+{{image_right("txtw-itrsmrks-02.png")}}
+{{br}}
+
+((*cutcopypaste.rb*))
+
+ #!/usr/bin/env ruby
+ require 'gtk2'
+
+ # Copy the selected text to the clipboard and remove it from the buffer.
+ def cut_clicked (txtvu)
+ clipboard = Gtk::Clipboard.get(Gdk::Selection::CLIPBOARD)
+ txtvu.buffer.cut_clipboard(clipboard, true)
+ end
+ # Copy the selected text to the clipboard.
+ def copy_clicked (txtvu)
+ clipboard = Gtk::Clipboard.get(Gdk::Selection::CLIPBOARD)
+ txtvu.buffer.copy_clipboard(clipboard)
+ end
+ # Insert the text from the clipboard into the text buffer.
+ def paste_clicked (txtvu)
+ clipboard = Gtk::Clipboard.get(Gdk::Selection::CLIPBOARD)
+ txtvu.buffer.paste_clipboard(clipboard, nil, true)
+ end
