스윙에서 테이블 모델 또는 GUI 새로 고침 Java

Question

내가 작업 해본 프로그램에서 새로운 데이터로 테이블을 새로 고침해야합니다. 현재 GUI를 처음 접한 이래로 새로운 GUI로 전체 GUI를 새로 고칠 예정이었습니다. 내 프로그램에서이 작업을 수행하지만 이전 GUI에서 빌드를 마칩니다.

프로젝트를 계속 진행하고 다시 빌드 할 수있을 때까지 진행하려면 두 가지 중 하나를 수행하고 싶습니다. 이전 GUI를 무효화하거나 새 GUI를 사용하거나 테이블 모델을 편집하십시오. 지금은 JTable으로 생성 한 이후로 DefaultTableModel을 사용하고 있습니다. 세 키 파일은

AppGUI에서 무효화 및 다시 그리기를 수행하거나 티커 검색을 실행할 때 테이블 모델을 업데이트하는 방법은 무엇입니까? (나는 GUI 새로 고침이 이상적이지 않을 수도 있음을 알고 있지만 버전에 대한 최소한의 재구성으로 계속 진행하고 싶다.) 누군가가 나를 따라 프로젝트를 움직일 수있는 통찰력이 있다면 그것은 위대 할 것입니다. 추신 : 두 번째 gui가 이전 gui에서 어떻게 새로 고쳐 졌는지 보려면 창을 최대화해야합니다.

Answer 1

테이블 모델을 수정하기 만하면됩니다. 뷰 자체를 새로 고침 할 적절한 이벤트를 발생시킵니다. 예를 들어, 새 행을 추가합니다 :

DefaultTableMode model = (DefaultTableModel) table.getModel(); 
model.addRow(newRow); 

가 javadoc of DefaultTableModel 가능한 모든 작업을 알고 찾습니다. 그리고 tutorial about JTable을 읽으십시오.
