REQUIREMENTS

Curses::Widgets

DESCRIPTION

Curses::Widgets::TextMemo provides simplified OO access to Curses-based single line text fields. Each object maintains its own state information.

METHODS

    new (inherited from Curses::Widgets)



  $tm = Curses::Widgets::TextMemo->new({
    CAPTION       => Memo,
    CAPTIONCOL    => blue,
    COLUMNS       => 10,
    MAXLENGTH     => undef,
    LINES         => 3,
    MASK          => undef,
    VALUE         => ,
    INPUTFUNC     => \&scankey,
    FOREGROUND    => white,
    BACKGROUND    => black,
    BORDER        => 1,
    BORDERCOL     => red,
    FOCUSSWITCH   => "\t",
    CURSORPOS     => 0,
    TEXTSTART     => 0,
    PASSWORD      => 0,
    X             => 1,
    Y             => 1,
    READONLY      => 0,
    });



The new method instantiates a new TextMemo object. The only mandatory key/value pairs in the configuration hash are <B>XB> and <B>YB>. All others have the following defaults:



  Key           Default   Description
  ============================================================
  CAPTION         undef   Caption superimposed on border
  CAPTIONCOL      undef   Foreground colour for caption text
  COLUMNS            10   Number of columns displayed
  MAXLENGTH       undef   Maximum string length allowed
  LINES               3   Number of lines in the window
  VALUE                 Current field text
  INPUTFUNC   \&scankey   Function to use to scan for keystrokes
  FOREGROUND      undef   Default foreground colour
  BACKGROUND      undef   Default background colour
  BORDER              1   Display a border around the field
  BORDERCOL       undef   Foreground colour for border
  FOCUSSWITCH      "\t"   Characters which signify end of input
  CURSORPOS           0   Starting position of the cursor
  TEXTSTART           0   Line number of string to start
                          displaying
  PASSWORD            0   Subsitutes * instead of characters
  READONLY            0   Prevents alteration to content



The <B>CAPTIONB> is only valid when the <B>BORDERB> is enabled. If the border is disabled, the field will be underlined, provided the terminal supports it. The <B>MAXLENGTHB> has no effect if left undefined.

    draw



  $tm->draw($mwh, 1);



The draw method renders the text memo in its current state. This requires a valid handle to a curses window in which it will render itself. The optional second argument, if true, will cause the field’s text cursor to be rendered as well.

HISTORY

1999/12/29 — Original text field widget in functional model
