NAME ^

Curses::UI::Common - Common methods for Curses::UI

CLASS HIERARCHY ^

 Curses::UI::Common - base class

SYNOPSIS ^

    package MyPackage;

    use Curses::UI::Common;
    use vars qw(@ISA);
    @ISA = qw(Curses::UI::Common);

DESCRIPTION ^

Curses::UI::Common is a collection of methods that is shared between Curses::UI classes.

METHODS ^

Various methods

Text processing

split_to_lines ( TEXT )

This method will split TEXT into a list of separate lines. It returns a reference to this list.

scrlength ( LINE )

Returns the screenlength of the string LINE. The difference with the perl function length() is that this method will expand TAB characters. It is exported by this class and it may be called as a stand-alone routine.

text_dimension ( TEXT )

This method will return an array containing the width (the length of the longest line) and the height (the number of lines) of the TEXT.

text_wrap ( LINE, LENGTH, WORDWRAP )
WORDWRAP ( )
NO_WORDWRAP ( )

This method will wrap a line of text (LINE) to a given length (LENGTH). If the WORDWRAP argument is true, wordwrap will be enabled (this is the default for WORDWRAP). It will return a reference to a list of wrapped lines. It is exported by this class and it may be called as a stand-alone routine.

The WORDWRAP and NO_WORDWRAP routines will return the correct value vor the WORDWRAP argument. These routines are exported by this class.

Example:

    $this->text_wrap($line, 50, NO_WORDWRAP);

Reading key input

CUI_ESCAPE ( )
CUI_TAB ( )
CUI_SPACE ( )

These are a couple of routines that are not defined by the Curses module, but which might be useful anyway. These routines are exported by this class.

get_key ( BLOCKTIME, CURSOR )

This method will try to read a key from the keyboard. It will return the key pressed or -1 if no key was pressed. It is exported by this class and it may be called as a stand-alone routine.

The BLOCKTIME argument can be used to set the curses halfdelay (the time to wait before the routine decides that no key was pressed). BLOCKTIME is given in tenths of seconds. The default is 0 (non-blocking key read).

Example:

    my $key = $this->get_key(5)
