New Revision: 97280
URL: http://svn.digium.com/view/asterisk?view=rev&rev=97280
Log:
add support for textareas, used for various dialog windows on the gui.
The main code to implement the textarea is in console_board.c,
and uses a simple png image with the font, blitting characters
on the designated areas of the main screen.
Additionally we provide some annotations in the image used
as a skin to indicate which areas are used for text messages.
(images will be committed separately).
At the moment the dialog area is only used to display a running
counter, just as a proof of concept.

+ * Message board implementation.
+ *
+ * A message board is a section of an sdl screen where
+ * messages can be printed, like on a terminal window.
+ * The text is stored in a buffer
+ * of fixed size (rows and cols). A portion of the buffer is
+ * visible on the screen, and the visible window can be moved up and
+ * down by dragging.
+ *
+ * TODO: font dynamic allocation
+ *
+ * OLD: The physical section displayed on the screen is defined
+ * as keypad element, (the name is defined in the `region' variable
+ * so the board geometry can be read from the skin or from the
+ * configuration file.
+ *
+ * OLD: To define a message board:
+ * - declare a board in the gui_info structure;
+ * - define a region name in the keypad skin and update
+ * the gui_key_map list;
+ * - add and manage focus events on its.
