   5 # 11/28/2003 - Jeff Grimmett (grimmtooth@softhome.net)
   6 #
   7 # o Changed the event binding slightly.
   8 # o There are issues with the GetReplaceText() method of the
   9 #   FindDialogEvent. Must be retested when this is fixed.

  98 FindReplaceDialog is a standard modeless dialog which is used to allow the user
  99 to search for some text (and possibly replace it with something else). The actual
 100 searching is supposed to be done in the owner window which is the parent of this
 101 dialog. Note that it means that unlike for the other standard dialogs this one
 102 <u>must have a parent window</u>. Also note that there is no way to use this
 103 dialog in a modal way; <b>it is always, by design and implementation, modeless</b>.
 104
 105 FileReplaceDialog requires the use of <b>FindReplaceData</b>. This holds the
 106 data for the dialog. It is used to initialize the dialog with the default values
 107 and will keep the last values from the dialog when it is closed. It is also
 108 updated each time a FindDialogEvent is generated so instead of using the
 109 FindDialogEvent methods you can also directly query this object. <b>Care must be
 110 taken not to use this object after the dialog is destroyed.</b> The data within
 111 will be invalid after the parent dialog is destroyed.
