mred:get-text-from-user

• (mred:get-text-from-user message caption default-value parent x y center?) -> string or #f
      message : string
      caption = "Input text" : string
      default-value = "" : string
      parent = current active frame : wx:window% object or null
      x = -1 : small integer
      y = -1 : small integer
      center? = #t : boolean

  Pops up a dialog box with title set to caption, message message, and a default value default-value. The user types in text and presses ``OK'' to return this text or ``Cancel'' to return #f.

  If center? is not #f, the message text (which may include new line characters) is centered, otherwise the message is left-justified.

  The dialog box's width is determined by the width of the message.

  This function uses a mred:edit%, not a wx:text%, and it function returns #f, not null when canceled, unlike wx:get-text-from-user.
