Curses-UI-0.63

Changes for version 0.63

2001-01-16: - Added a CLASS HIERARCHY section to the documentation of each Curses::UI class.
- All focusable objects now have the following event callbacks: -onfocus / onFocus() -onblur / onBlur()
- The Curses::UI::Calendar widget now fully supports the years 0 - 9999, including the transition from the Julian to the Gregorian calendar (september 1752). This beats the use of timelocal/localtime (which would currently only support 1900 - 2038 IIRC).
- Added intellidraw() method to Curses::UI::Widget. If this method is called, the widget is redrawn, but only if it's visible (not hidden and in topwindow) and if intellidraw is enabled (-intellidraw data member has a true value).
  - This routine can be used to be able to redraw widgets on a status change, without having to figure out yourself if this wouldn't clutter up the screen. The -intellidraw option is meant for widget builders (see for example the Checkbox code).
- Incorporated intellidraw() method in:
  - Curses::UI::Window
  - Curses::UI::Label
  - Curses::UI::Calendar
  - Curses::UI::Buttonbox
  - Curses::UI::Listbox (+ descendants)
  - Curses::UI::Checkbox
  - Curses::UI::Popupbox
  - Curses::UI::Progressbar
  - Curses::UI::TextEditor (+ descendants)
  - Curses::UI::SearchEntry
- Added a little example application to demonstrate the new intellidraw feature: examples/demo-intellidraw
2001-01-15: - Changed the displaying of the calendar widget a little. The topbar showing a date is only highlighted if the cursor is on the selected date.
- Renamed some widgets (now we still can). I think there are too many capitals in them...
  - Curses::UI::ListBox renamed to Curses::UI::Listbox
  - Curses::UI::CheckBox renamed to Curses::UI::Checkbox
  - Curses::UI::MenuBar renamed to Curses::UI::Menubar
  - Curses::UI::MenuListBox renamed to Curses::UI::MenuListbox
  - Curses::UI::PopupBox renamed to Curses::UI::Popupmenu
  - Curses::UI::ProgressBar renamed to Curses::UI::Progressbar
  - Curses::UI::ButtonBox renamed to Curses::UI::Buttonbox
  - Curses::UI::RadioButtonBox renamed to Curses::UI::Radiobuttonbox
  - Curses::UI::Dialog::FileBrowser renamed to Curses::UI::Dialog::Filebrowser
- Added event callbacks to:
  - Curses::UI::Calendar (-onchange / onChange())
  - Curses::UI::Listbox (-onchange / onChange())
  - Curses::UI::Checkbox (-onchange / onChange())
  - Curses::UI::TextEditor (-onchange / onChange())
  - Curses::UI::TextEntry (-onchange / onChange())
  - Curses::UI::PasswordEntry (-onchange / onChange())
  - Curses::UI::Popupmenu (-onchange / onChange())
- The options that can be passed to the new() methods, are case insensitive now. So it is perfectly okay to write:
  - $win->add( 'cb', 'Checkbox', -Label => 'Demonstration widget', -onChange => sub { exit() } );
