### Textview and Window and Statusline now can print colored text
    Colored interface not yet final.

### Some experimental work that will trickle into core classes in 1.5.0

**2011-10-06**
## 1.3.1 or 1.4.0

### Major cleanup of widget class
  Scrollpane support (buffering stuff all removed)

### TabbedPane
  Corrected, major changes

### dsl_accessor and dsl_property
  Now return self so we can chain.

### return values of some keys (Class Form)
  Earlier not returning anything meaningful or returning last_key
  Now return NO_NEXT_FIELD or NO_PREVIOUS_FIELD

### j and k keys used for down and up where possible
   e.g. button and its children including checkbox

  close.
  * many more minor adjustments, tweaks, issues

**2011-09-26**
## 1.3.0

### Moving to ffi-ncurses
   Essentially code changes for ffi-ncurses. ncurses gem no longer supported
   as it was painful to install. Required ffi-ncurses >= 0.4.0
   
   Some bugfixes in demos and samples due to changes in 1.2.0, or ruby 1.9,  which went
   unnoticed.

### Deprecations
   Some classes being deprecated:
   - SplitPane (use vimsplit instead)
   - ScrollPane (no substitute) Code supporting scrollpane will be removed
   by 1.3.1 or 1.3.2  and this will not work.

### Tabbedpane
   Not working correctly since moving to ffi-ncurses. Will be completely
   rewritten by 1.3.2.

**2010-09-11**
## 1.2.0

### Additions

 - App class that allows easy application development (like Shoes)
 - MultiSplit class: Multicolumn widget (like SplitPane but allows many splits). 
   aka Column Browse pattern (like OSX Finder). See examples/testmultisplit.rb
 - Added Progress Bar class

 - Added methods to Menu (rmenu.rb), so easy creation through DSL. See
 examples/menu1.rb

 - Added VimSplit - can have multiple splits stacked and flowed
 - Added Tree     - tree control
 - Added Scrollbar class
 - Added Tabular - quick readonly tabular data generator that can be used with
 listboxes or textviews.
 - Added BasicList - a stripped down, readonly version of Listbox.
 - 

### Changes

 - Field class now passes InputDataEvent when firing event, not self.
   Earlier, user trapping :CHANGE would not know what happened (delete,
   insert, etc) and what char was added, deleted.
 - List and ListData and ListSelection listener
   Many changes, new methods, def list(), space bar selects,
   List listens to selection changes, selectionEvent contains List as source
   not ListSelectionModel.
 - Widget checks event names before firing and binding to save time in wrong
 events.
 - Listbox, some refactoring of `repaint`. Added convert_value_to_text since
 we subclass this a lot.
 - Listcellrenderer: refactoring and changes, will break extending classes!!
 - Combolist - popup on spacebar
 - replaced to_print_borders with suppress_borders in list related classes

### Bugfixes

 - TextArea would crash if user entered long line with no space (line >
 display length) - fixed

 - Menu items will not show mnemonic highlighted, if disabled. 
   They will not fire if mnemonic key pressed, when disabled.

**2010-08-30 11:59**
## 1.1.4

 - Some missing files such as tableextended.rb and vieditable
   These got missed out in the gemspec.
 - Added slice! to listdatamodel
 - Also see ruby 1.9.2 changes below

**2010-08-23 11:50**
## ruby 1.9.2 related changes

 Changes in 1.9.2 require the following changes:
  - $: no longer includes ".". 
    Fixed 2 examples.
  - hash_update: cannot update hash during iteration
    Modified rwidget.rb and rtable.rb

    (Ref http://svn.ruby-lang.org/repos/ruby/tags/v1_9_2_0/ChangeLog)

**2010-05-19 00:00** 
## Table - added tableextended.rb for extended functions on tables

Currently, increase or decrease column width using numeric args. 
You will have to bind the method to a key in your app.

**2010-05-13 00:00** 
## Table - adding vim keys for navigation

If table is not editable, then j k l h gg G etc may be used for navigation.

**2010-03-01 00:00** 
## Overhaul of tabbedpane

Simplified, and it more or less completely makes sense now.
A component may be added directly without creating a form
which allows the TP to set row, col, and height width.

At this moment, it no longer creates a form automatically, you have to call
tp.form(tab) to get a form associated with the tab. Check code for latest on
this. Or check samples: testtpane.rb and testtpane2.rb.

**2010-02-18 22:58** 
## RFED16 new simplified buffering

Major changes. Most widgets redone (buffer part).
Containers majorly done. Table and TabbedPane still pending.

**2009-11-03 23:30**
## tabbedpanes ##

Now on first click of tabbed button, form is painted.
A form.repaint for the lower form was required.

frmincr200911032330.tgz
* * *
**2009-11-03 00:19**
## some progress on tabbedpanes ##

Ugly hacking and I really haven't a clue what's happening
since there's internal forms working.
Anyhow, its now showing up, can see form cursor moving.
Does not show up immediately, have to press key several times for form to display.

frmincr200911030018.tgz
* * *
**2009-11-02 13:15**
## before rtabbedpane ##

After all the changes, the new tabbedpane is not printing the form fields.
Working on that now.

frmincr200911021314.tgz
* * *
**2009-11-02 12:13**
## splitpane and scrollpane working ##

Both are working. Changes to copywin had caused issues. And printborder.
Decreasing comp width does not reduce pad size, but pad keeps printing larger size.
So in Splitpane it was overwriting. Now in Pad we maintain sheight as comp's height.
Major change in pad, but hope it works and doesn't bomb out somewhere.

frmincr200911021212.tgz
* * *
**2009-11-02 01:03**
## SplitPane retouching ##

began majorly misprinting after changes to printborder and copywin().
ALmost corrected. Still some issues in copywin which are making separator and border
to get eaten up.

frmincr200911020102.tgz

**2009-11-01 22:28**
## scrollbars in scrollpane ##

Added scrollbars in scrollpane. Sized and positioned nicely.

frmincr200911012228.tgz
* * *
**2009-11-01 01:05**
## scrollpane WIP ##

scrollpane with viewport and child object
i can see the child within. have to test scrolling now.
Issue is largely with copywin which gives errors.

## buffering ##

major change is buffering added (using pad)
height and width added to Widget
Splitpane added (midway)

frmincr200910301746.tgz
* * *
**2009-10-07 10:14**
## Prior to change in next_column ##

Currently, after last visible column tab goes to next row.
We want to scroll if more columns.
At present, table will not print if a col goes out of bounds. but this does not impact
first or last column to print variables.

frmincr200910071012.tgz
* * *
** 2009-10-05 11:00 **
## Horizontal scrolling in tables - some cleaning ##

When increasing the size of a column, other cols could write
outside the table. Fixed.

* * *
** 2009-10-05 00:00 **
## Making changes for 1.9 and testing ##

Mostly key related changes.
However, there could be some string index change lurking around

* * *
** 2009-02-22 20:48 **

## Released 0.1.2 ##

- search in textview with wrap, case insensitive, highlighting searched text
- table can have nil data
- tabbed pane has ok_cancel button, ok by default
- table autosizing - required for adhoc queries
- table horizontal scrolling
- editing when more columns than viewable in table
- confirm dialog, normal mnemonics for buttons

* * *
** 2009-02-17 12:10 **
## added table markers for data and columns before and after on border ##

also added putting space in intercell area, but today i am not getting any 
junk there anywaym while scrolling etc.

* * *
** 2009-02-16 22:10 **
## added edit_length to TableColumn ##

This is max editable length of editor component in tables.

* * *
** 2009-02-13 13:48 **
## added button_type to tabbed pane ##

Now buttons at bottom of tabbed pane. Will return selected_index
to caller.
Uploaded to github, will be included in 0.1.2.

* * *
** 2009-02-12 22:48 **
## Code to stop table from printing a column if exceeding bounds ##

Uploaded to github, will be included in 0.1.2.

EXPERIMENTAL CODE: Affects only tables. Now table will not print a column or header
if columns width causes it to exceed width of table.

This means if you have a single column which is wider than table
then it wont print. In Listboxes we always truncate data and pass to
renderer. We could do that here, but it could get messy.

* * *
**2009-02-12 **
## Missed one parameter in Table's repaint, and some Table Cell Renderers

Fixed and uploaded as 0.1.1

* * *
**2009-02-11 00:57**
## Path changes in order to make first gem ##

the first gem is ready 0.1.0. So various path changes (removed all the lib's in require)

frmincr200902110056.tgz
* * *
**2009-01-21 18:30**
## Class Action ##

Added a class Action to centralize actions or behavior.
Popupmenu creates a jmenuitem with an action.

frmincr200901211826.tgz
* * *
**2009-01-20 22:50**
## Class PopupMenu ##

Based on menubar, a popup menu. Intended to be used with widgets / components.

## Alpine Style Key Label Printing ##

See testtodo.rb for example.
Print Alpine Style labels at bottom

frmincr200901192140.tgz
* * *
**2009-01-19 15:53**
## Table Changed Event ##

One may either trap the CHANGED event of a component OR
a TABLE_EDITING_EVENT which gives us previous and new values, previous row and col.
This will fire for each cell exited, and on editing stopped (if a user presses ENTER after editing).

One example would be to set a date_modified if any column of a row changes. 

Also am firing CHANGED from table for its cells.

frmincr200901191548.tgz
* * *
**2009-01-18 22:11**
## listbox, combo case insensitive match ##

Char matches use casecmp

Field was not calling process_key(ch) - now calling super in handle_key, so process_key is called
in handle_key.

frmincr200901182210.tgz
* * *
** 2009-01-18 12:37 **
## modified? and def modified tf##

changed fields modified? to check for change in field value

Field ESC puts back original value

TAB and BACKTAB in table. so you need to M-tab out of it.

**2009-01-17 01:56**
## Tables: editing options more polishing ##

also, columns may be marked as non-editable
calling on_leave of component 


frmincr200901170155.tgz
* * *
**2009-01-16 20:13**
## Table - cyclic traversal to next column, auto editing of cells ##

Automatic editing on tabbing in and out on Table.
Trying this out. USe Alt-Tab for going to next cell if you are editing a cell.
If not editing then RIGHT and LEFT work.

frmincr200901162012.tgz
* * *
**2009-01-16 00:31**
## Tables: Events and Listeners implemented ##

on enter row, col and cell.
Table Column property change
Various others.

frmincr200901160030.tgz
* * *
**2009-01-15 01:23**
## Events in tables added ##

(just days backup)

frmincr200901150122.tgz
* * *
** 2009-01-15 00:17 **

Table on_enter and on_leave row, column and cell events

Also put key definitions for table and listbox in listkeys.rb
so they can be shared.
Fixed def handle_key of listbox so if key not handled, it still
tries further.

**2009-01-14 12:56**
## Forward and backward searching in Listbox ##

M-f to start a forward search (asks for regex)
M-F to start a backward search (asks for regex)
M-g to keep searching forward
M-G to reverse direction of search

## Table Editing ##

String, number, checkbox and combolist

frmincr200901130139.tgz
* * *

## Table editing is on ##

Testing and working out visual glitch in checkbox edit.
One extra char displayed by editor but not by renderer.
So a white space gets left over.

## editable lists: check and combo boxes ##

Now you may edit a list of checkboxes or combo boxes

**2009-01-11 16:32**
## combo box cell renderer in listbox ##

almost done. some touching up

frmincr200901111632.tgz
* * *
**2009-01-11 00:28**
## ComboBoxCellRenderer ##

For lists, to display combo boxes.
Althoght does not make much sense. THe normal list box already has
selection of rows. so its like a list which is now editable and selectable.

This has only checkboxes. How do i pass in text in addition to booleans
given that the method interface of renderers takes one value.

frmincr200901110026.tgz
* * *
**2009-01-10 23:18**
## About to move selector code up ##

To avoid duplication in renderers

**2009-01-08 01:41**
## firing property change and others ##

Some major changes (internal)

1.   In order not to repaint the entire form each time, we must only repaint a widget when modified.
     However, as can be seen, widgets are being modified by other widgets. Thus whenever a property
     is changed, we need a flag to be set that repainting is required.

    Thus, copied dsl_accessor and made dsl_property. Whenever, such props are modified, a property 
    change is now fired, and repaint_required is set to true.
    I am currently changing this. What this means is that on startup, fire_prop_change will be called
    many times, and i need to avoid this on first time instantiation. TODO.
    
2. The tricky part was text_variables. When there value changes any widget (such as label) auto
   changes. When a text_variable is defined for  field, internally that field, adds itself as a 
   dependent. When its value is changed, it fires a change to the dependent field.

3. The real worrisome part was this:
   When user passes in a hash in the constructor, i was directly setting variables, NOT calling
   methods. Tracked this down. Now i am calling methods and not setting variables. See rwidget.rb
   instance_variable_set (top). Only throrough testing will tell how much this change
   will affect stuff. Maybe not.

## New Listbox ##

with cleaner scrolling code, and cell renderer
Largely done.

frmincr200901072335.tgz
* * *
**2009-01-07 00:36**
## Field storing datatypes ##

1.   set_buffer updates datatype of data
2.   get_value reverts to original datatype (stored as a string since many methods
     do check length etc

Widget binds_keys
Certain widgets like tables etc would like to bind_keys which could be used by other
widgets. Such as left and right keys or del key. So these should not be at the program
level, but only at widget level.

## rtable with scrolling ##

## Boolean buttons use "variable" not "text_variable" ##

That was a misunderstanding. Checkbutton, Toggle and Radio use "variable" which 
updates or gets updated by any changes.

frmincr200901011300.tgz
* * *
**2008-12-31 23:46**
## Variable modifications ##

Had to move to get_value and set_value so that Variable could support a hash or array without
anything else changing.
That means if a set of checkboxes and radio buttons are based on one Variable which is a Hash,
they will continue working as before, since they always pass t heir name as a second parm to set_value 
(whch is used as a key, if Variable is a hash).
Earlier i was using value= but that does not allow 2 params.
In the case of a hash, even retrieving requires the widgt name as key.
So seeing how many params are coming in does not work. Thus moving from value() and value= to get and set value.

Currently, its there as RVariable. Will be moved to Variable in a day or so.

**2008-12-23 23:49**
## Migrated buttons to mnemonic and ampersand for hotkeys ##

Unerline will result in underline, overriding that created by ampersand, but not register key.
mnemonic will register alt-key and underline first occurence
Using ampersand will register and underline given occurrence.

## Added observers to events ##

An object can listen in to events of another. Could be a hack.
Helps if user creates an object which further creates others. User binds actioon to top level object.
But we want internal objects events to also fire action.

frmincr200812231337.tgz
* * *
## Multiple bindings for each event ##

Each object can bind its actions without fear of overwriting each other.
Variables update_command also stacked.

## CheckBoxMenuItem ##

Implemented a checkbox menu item, works but i am not pleased, quite dirty.

Widgets are tied to a form, for ease of construction.
In the case of menus they are not, and menus print in a different manner.

Submenu should also have been a class, perhaps.

## sqlpopup and keymapper ##


We have a much simpler than VER keymapper. Code is small. 
      - Uses keyboard.rb from VER project to give us ESC and meta/alt keys.
      - We use same syntax for configuring such as class.let :mode do etc.
      - Provided:
               - single keys combinations
               - a mode with its set of keys
               - dual keys such as C-x C-c or C-x p etc which do not change mode.

frmincr200811120036.tgz
* * *
**2008-11-11 23:40**
## sqlpopup our own modes and key ##

allows cx mode with its keys
but its looks okay for a mode
for a multiple key we would prefer to say : C-c C-x
and not create a separate context./mode.

SIMPLE view has column name and data per row.
ALTERNATING has name followed by data in next row.

A lot of stuff has gone into Field, valid, default, postproc
This happens on get_value, set_value and field_term.

## email multiline format ##

This was having to be called by the user in form_post_proc
Now before save, heightwill be checked.

Howevr, this should happen auto. Added get_value and set_value in FIELD. and maybe thats 
where it shouldhappen.
But we have to use it, too. We are using @current.

## Edit DSL ##

Finally got the email program running from a DSL.
One job pending still ... update_current_values.
Some things could be generated at generate time, setup observers, rather
than at load time.

Still then need to start getting a  proper datasource into place.

## C-c ##

1.  Now getting c-y, c-z, c-s and c-q
2.  We seem to have lost C-c
    The trap is eating it up totally.
    Finally i am trapping and doing an ungetch for which had to open the Ncurses class
    and fix.
3. Also allowing user to bind_key and use the REQ_ values
4. Fixed bugs so that keys_handled is called in rbeditform.

## highlighting field ##

Some cute coding, and we've got the current field label hightlighted.
Sadly Message Text shows that : after it ;-(. That's the default.

Now to get the silly keylabels functional.

## Edit screen ##

More refactoring on editapplication and rbeditforms.
Moved a lot iinto form. App should have less. Form should not keep calling into app.

Also this version has fields centered abd reverse video. I am now going the alpine way.

## gen4.rb EDIT FORM ##

I have the old gen2.rb redone into a datasource, rbeditform, editapplication.
Just about coming up!
Still many errors de to references from form to app.

Totally unclear here as to what the app is doing, and should it have all thefunctinolity
in it or not. Too much calling from form to app.

Its quite a mess and needs a major overhaul.

I also need to make changes so that rt_hashes and rt_fields dont have to be passed.

Application should only have what is required by the main app for setting up and cleaning ==
not all the stuff for regular work. 

Form should contain all else.

## MENU ##

Updated menu.skel so it generates a class that inherits from menuApplication.
It generates a menu class.
It is working !

## running from menu ##

1.  Got the menu program working after all the changes in base classes.

2. Got programs running from menu. Apparently, some panels were not being 
   destroyed, so there was a BUS ERROR in update_panels.

3. There was a warning of BOTTOM_WIN_WIDTH already defined that was messing the screen
   and i could not see it clearly, so it bugged me a long time.

All's okay but the skel programs have to be updated. The menu DSL minp1 has to be rerun to see
if it gives correct output as per menu1.rb.
Basically, panels have to be returned with windows so they can be destroyed.

Can view files using padreader using view_file(filename).
Have not put buttons, and headers like in panelreader yet.

## form specific key labels - wip ##

It is working but not standard
Need to simplify it.
qapp returns keylabels but does not support a keys_handled
tapp has keyhasharray but does not generate its labels.
we should junk app labels. that complicates things.

## tab and enter behaviour in query apps ##

Tab moves between fields in query form
Tab in table moves back to query form.
Enter in table runs query as b4, but now also moves focus to table

## HELP ##
Using __FILE__ in  constructor of major programs to determine a name for file
to check for help when user presses ?
Application.rb checks for this.

## panelreader ##
deleting panel in ensure otherwise previous screen wuld be scr00d.

## help ##
Added a generic application_key_handler in Application.rb which shows
page specific help. Currently, i have to work that out. Application should
define a page. It by default pops up TODO !

More polishing on panelreader.rb
But cannot get the line numbers correct.
Also if I display line # on top, then cursor remains there.
If i put the print statemnet at beg of loop, the line number is wonky.
It is correct at end of loop, but then the cursor is stuck on top.

**2008-10-09 13:34**

panelreader and editor
so i can pop it up and view or edit content or a file

## datasource class ##

  Made this more reusable. Lots of silly stuff changed.
  * now it has a constructor.
  * does not do any work other than init.
  * more reusable than earlier.

## handling of cursor and selection in subseq queries ##

especially if:
  
  *  fewer queries returned in second query
  *  no queries returned in second query

  Now cursor will always be in row one after a fresh query when you tab.
  Can't tab in if no rows.

* * *
**2008-10-08 17:51**

## get_curr_index bug ##

this was returning one more (base 1) so some users were doing -1
Some methods were getting wrong curr_item like the handle_? methods.

User cannot tab into table if no data.

Issue of wrong header count if no rows also fixed.

**2008-10-08 14:48**

Moved stuff to Datasource class.
Also checked out more stuff from DSL
Added keys_handled to DLS and tested it.

**2008-10-07 22:40**

1. based on datatype, aligning fields in table 
2. based on datatype, using = in search query for integer and real and smallint
