The TTMSFNCFindDialog is a component with predefined specifiers for searching a text. It also supports auto history, closing if a text was found and has an extended view.


To show the dialog, call the Execute method.

procedure TForm1.Button1Click(Sender: TObject);

Use the OnFind and OnFindPrevious events to handle the search. Each events have an AFound parameter that can be set to True if a match was found. If AFound is set to True and the "Close if found" checkbox is enabled, the dialog will automatically close.

procedure TForm1.TMSFNCFindDialog1Find(Sender: TObject; AFindText: string; var AFound: Boolean);
  c: Boolean;
  c := fdoCaseSensitive in TTMSFNCFindDialog1.Options;
  if DoMyOwnSearchLogic(AFindText, AMyOriginalText, c) then
    AFound := True;

More/extended view

When the more/extended view is enabled, "More" button will appear in the bottom right corner. This button can toggle between the single and multi-line search fields. If the multi-line search field is visible the single-line will be disabled. The same events are triggered for both views.
