모달 대화 상자를 올바르게 모방하고 입력을 기다리는 방법은 무엇입니까?

Question

Firemonkey에서 Delphi 10.1 Berlin에서 메시지 대화 상자가 변경되었으며 MessageDlg은 새 대화 상자 서비스 사용을 위해 더 이상 사용되지 않습니다. 그러나, 어쨌든, 나는 시스템 대화 상자 (적어도 메시지)를 우회하고 대신 내 자신의 동기식 양식 대화 상자를 사용하고 싶습니다.

이 작업을 수행하기 위해 하나의 양식을 작성했으며 작동합니다. 그러나 매우 지저분하며 특히 어떻게 기다리는 지에 대한 방법입니다. 나는 콜백 프로 시저를 사용하고 싶지 않기 때문에, 보통의 모달 다이얼로그처럼 사용자의 응답을 대신 기다리는 MessageDlg의 자체 버전을 원한다. (. 사실, 난 내 MsgPrompt 전화) 특히

,이 자리에서 다른 일을 수행해야합니다

while not F.FDone do begin 
    Application.ProcessMessages; 
    Sleep(50); 
end; 

을 ... 분명한 이유.

콜백 프로 시저를 사용하지 않으려는 이유 중 한 가지 예가 메인 양식의 OnCloseQuery에서 사용해야하고 사용자가 닫기를 원한다면 사용자에게 메시지를 표시해야하기 때문입니다 . 사용자가 선택하기 전에 OnCloseQuery 이벤트 핸들러가 종료되기 때문에 불가능합니다.

기본 UI 스레드를 차단하지 않고 해당 입력을 동 기적으로 (모달 대화 상자를 모방 한) 적절하게 기다려야합니다. 민감도?
