Curses::Widgets::TextField - Text Field Widgets $Id: TextField.pm,v 1.103 2002/11/04 00:35:44 corliss Exp corliss $ use Curses::Widgets::TextField; $tf = Curses::Widgets::TextField->new({ CAPTION => 'Name', CAPTIONCOL => 'yellow', COLUMNS => 10, MAXLENGTH => 255, MASK => undef, VALUE => '', INPUTFUNC => \&scankey, FOREGROUND => undef, BACKGROUND => 'black', BORDER => 1, BORDERCOL => 'red', FOCUSSWITCH => "\t\n", CURSORPOS => 0, TEXTSTART => 0, PASSWORD => 0, X => 1, Y => 1, READONLY => 0, }); $tf->draw($mwh, 1); See the Curses::Widgets pod for other methods. Curses::Widgets::TextField provides simplified OO access to Curses-based single line text fields. Each object maintains its own state information.

new (inherited from Curses::Widgets)
$tf = Curses::Widgets::TextField->new({ CAPTION => 'Name', CAPTIONCOL => 'yellow', COLUMNS => 10, MAXLENGTH => 255, MASK => undef, VALUE => '', INPUTFUNC => \&scankey, FOREGROUND => undef, BACKGROUND => 'black', BORDER => 1, BORDERCOL => 'red', FOCUSSWITCH => "\t\n", CURSORPOS => 0, TEXTSTART => 0, PASSWORD => 0, X => 1, Y => 1, READONLY => 0, }); The new method instantiates a new TextField object. The only mandatory key/value pairs in the configuration hash are X and Y. 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 255 Maximum string length allowed MASK undef Not yet implemented 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\n" Characters which signify end of input CURSORPOS 0 Starting position of the cursor TEXTSTART 0 Position in string to start displaying PASSWORD 0 Subsitutes '*' instead of characters READONLY 0 Prevents alteration to content The CAPTION is only valid when the BORDER is enabled. If the border is disabled, the field will be underlined, provided the terminal supports it. If MAXLENGTH is undefined, no limit will be placed on the string length. If BORDER is true, the widget will be enlarged to three columns and two more columns to make room for the border.

draw
$tf->draw($mwh, 1); The draw method renders the text field 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. (c) 2001 Arthur Corliss (corliss@digitalmages.com)
