   3 # o Updated for wx namespace
   4 #
   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.

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