Prima::EditDialog(3)

NAME
Prima::FindDialog, Prima::ReplaceDialog - standard interface dialogs to find and replace options selection.

DESCRIPTION
The module provides two classes - Prima::FindDialog and Prima::ReplaceDialog; Prima::ReplaceDialog is exactly same as Prima::FindDialog except that its default findStyle property value is set to 0. One can use a dialog-caching technique, arbitrating between findStyle value 0 and 1, and use only one instance of Prima::FindDialog.

The module does not provide the actual search algorithm; this must be implemented by the programmer. The toolkit currently include some facilitation to the problem - the part of algorithm for "Prima::Edit" class is found in "find" in Prima::Edit, and the another part - in examples/editor.pl example program. Prima::HelpWindow also uses the module, and realizes its own searching algorithm.

SYNOPSIS
   use Prima::StdDlg;

   my $dlg = Prima::FindDialog-> create( findStyle => 0);
   my $res = $dlg-> execute;
   if ( $res == mb::Ok) {
      print $dlg-> findText, " is to be found\n";
   } elsif ( $res == mb::ChangeAll) {
      print "all occurences of ", $dlg-> findText,
         " is to be replaced by ", $dlg-> replaceText;
   }

The "mb::ChangeAll" constant, one of possible results of "execute" method, is defined in Prima::StdDlg module. Therefore it is recommended to include this module instead.
