Curses-UI
view release on metacpan or search on metacpan
a language module of your own, please send it to
me. I'll then include it in the distribution.
- Changed all year 2001 occurrances in the Changelog
to 2002. Thanks to Mark Overmeer (mr. Mail::Box) for
noticing that I was one year off ;-)
- Made sure that upon deleting a widget from a
container, its subwindows are deleted.
- Created calendar dialog (request made by Ravi Pina).
Also added a little demo to demo-widgets for this
new dialog type. The dialog is accessable via
Curses::UI ($cui->calendardialog).
- Changed the unpacking of mouse events a little
(thanks to William Setzer for the hint on
unpack("sx2i3l", $MEVENT) instead of
unpack("i5", $MEVENT)).
Version 0.70
============
2002-01-31 - After a lot of hacking on the resize code
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
- 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
2002-01-15: - 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

=head1 SYNOPSIS
use Curses::UI;
my $cui = new Curses::UI;
my $win = $cui->add('window_id', 'Window');
my $calendar = $win->add(
'mycalendar', 'Calendar',
-date => '2002-1-14'

my $date = $calendar->get();
=head1 DESCRIPTION
Curses::UI::Calendar is a widget that can be used to create
a calendar in which the user can select a date. The calendar
widget looks like this:
+----------------------+

=item * B<-onchange> < CODEREF >
This sets the onChange event handler for the calendar widget.
If a new date is selected, the code in CODEREF will be executed.
It will get the widget reference as its argument.
=item * B<-drawline> < CODEREF >
This option specifies whether or not a line should be drawn under
the calendar.
