NAME ^

Win32::GUI::Textfield - Create and manipulate textfield controls

DESCRIPTION ^

[TBD]

METHODS ^

Common methods apply to most windows, controls and resources.

new

new(PARENT, %OPTIONS)

Creates a new Textfield object; can also be called as PARENT->AddTextfield(%OPTIONS). Class specific %OPTIONS are:

  -align         => left/center/right (default left)
      aligns the text in the control accordingly.
  -keepselection => 0/1 (default 0)
      the selection is not hidden when the control loses focus.
  -multiline     => 0/1 (default 0)
      the control can have more than one line (note that newline
      is "\r\n", not "\n"!).
  -password      => 0/1 (default 0)
      masks the user input (like password prompts).
  -passwordchar  => CHAR (default '*')
      The specified CHAR that is shown instead of the text with -password => 1
  -lowercase     => 0/1 (default 0)
      Convert all caracter into lowercase
  -uppercase     => 0/1 (default 0)
      Convert all caracter into uppercase
  -autohscroll   => 0/1 (default 1 (0 for a multiline Textfield))
      Automatically scroll to right as text is typed past the right
      margin;  If 0 for a multiline Textfield, then wrap to the next
      line.
  -autovscroll   => 0/1 (default 1)
      For a multiline Textfiled automatically scroll down as lines
      pass the bottom of the control.
  -number        => 0/1 (default 0)
      Allows only digits to be entered into the edit control
  -prompt        => (see below)
  -readonly      => 0/1 (default 0)
      text can't be changed.
  -wantreturn    => 0/1 (default 0)
      when dialogui => 1 is in effect, stops the <ENTER> key
      behaving as a click on the default button, and allows the
      key to be entered in a multi-line Textfield

The -prompt option is very special; if a string is passed, a Win32::GUI::Label object (with text set to the string passed) is created to the left of the Textfield. Example:

    $Window->AddTextfield(
        -name   => "Username",
        -left   => 75,
        -top    => 150,
        -width  => 100,
        -height => 20,
        -prompt => "Your name:",
    );

Furthermore, the value to -prompt can be a reference to a list containing the string and an additional parameter, which sets the width for the Label (eg. [ STRING, WIDTH ] ). If WIDTH is negative, it is calculated relative to the Textfield left coordinate. Example:

    -left => 75,                          (Label left) (Textfield left)
    -prompt => [ "Your name:", 30 ],       75           105 (75+30)

    -left => 75,
    -prompt => [ "Your name:", -30 ],      45 (75-30)   75

Note that the Win32::GUI::Label object is named like the Textfield, with a "_Prompt" suffix (in the example above, the Label is named "Username_Prompt").
