DesignGridLayout 경계선이 벗어납니다

Question

내 문제는이 코드가 스윙 GUI를 생성하고 내 랩톱의 디스플레이 범위를 벗어납니다. 왜? 레이아웃 라이브러리로 DesignGridLayout을 사용하고 있습니다. Why does my components go out of boundaries, please help me to align it with the necessary code

글쎄, 왜 안 :

이

는 코드는 답변에서 가져옵니다?

pack() 프레임이 원하는 하위 크기를 모두 표시하고 크기/최소 제한을 충족하는 데 필요한 크기가되도록 프레임을 표시하거나, 표시 할 항목이 많거나 해상도가 충분하지 않은 경우 창이 화면 밖으로 벗어날 수 있습니다. 말하자면 프레임이 최대화되면 이는 놀라운 문제입니다.
