libbls 0.1.0 (Default branch)
libbls is a highly efficient, flexible, and robust data manipulation library in the form of an editable buffer. It provides efficient insert, replace, delete, copy, and multiple undo and redo editing operations, in a fast and memory efficient manner, combining data from both memory and arbitrary sized chunks from files. A simple, intuitive, and yet powerful API provides the infrastructure needed to develop scalable applications that handle large volumes of data. Image

Gtk2::Editable(3pm)					User Contributed Perl Documentation				       Gtk2::Editable(3pm)

NAME

       Gtk2::Editable - wrapper for GtkEditable

HIERARCHY

	 Glib::Interface
	 +----Gtk2::Editable

METHODS

   string = $editable->get_chars ($start_pos, $end_pos)
       o   $start_pos (integer)

       o   $end_pos (integer)

   $editable->copy_clipboard
   $editable->cut_clipboard
   $editable->delete_selection
   $editable->delete_text ($start_pos, $end_pos)
       o   $start_pos (integer)

       o   $end_pos (integer)

   boolean = $editable->get_editable
   $editable->set_editable ($is_editable)
       o   $is_editable (boolean)

   new_position = $editable->insert_text (new_text, position)
       o   $new_text (string)

       o   ... (list)

   $editable->paste_clipboard
   integer = $editable->get_position
   $editable->set_position ($position)
       o   $position (integer)

   $editable->select_region ($start, $end)
       o   $start (integer)

       o   $end (integer)

   (start, end) = $editable->get_selection_bounds
       Returns integers, start and end.

SIGNALS

       changed (Gtk2::Editable)
       insert-text (Gtk2::Editable, string, integer, gpointer)
       delete-text (Gtk2::Editable, integer, integer)

       The "insert-text" signal handler can optionally alter the text to be inserted.  It may

       o   Return no values for no change.  Be sure to end with an empty "return".

	       sub my_insert_text_handler {
		 my ($widget, $text, $len, $pos, $userdata) = @_;
		 print "inserting '$text' at char position '$pos'
";
		 return;  # no values
	       }

       o   Return two values "($text, $pos)" which are the new text and character position.

	       sub my_insert_text_handler {
		 my ($widget, $text, $len, $pos, $userdata) = @_;
		 return (uc($text), $pos);  # force to upper case
	       }

       o   Return no values and modify the text in $_[1] and/or position in $_[3].  For example,

	       sub my_insert_text_handler {
		 $_[1] = uc($_[1]);   # force to upper case
		 $_[3] = 0;	      # force position to the start
		 return;  # no values
	       }

       Note that currently in a Perl subclass of a "Gtk2::Editable" widget, a class closure (ie. class default signal handler) for "insert-text"
       does not work this way.	It instead sees the C level "($text, $len, $pos_pointer)", where $pos_pointer is a machine address and cannot be
       used easily.  Hopefully this will change in the future.	A "signal_chain_from_overridden" with the args as passed works, but for anything
       else the suggestion is to use a "signal_connect" instead.
