배경/전경/글꼴/이미지의 SWT 테이블 셀 데이터 바인딩을 위한 Glimmer DSL

Glimmer은 table의 선언적 양방향 데이터 바인딩을 (비주얼 디자이너/GUI를 사용하지 않고) 한 줄의 코드로 간단한 발표자/모델 컬렉션에 가능하게 하는 최초의 소프트웨어 라이브러리였습니다!

items <=> [@presenter, :contacts, column_properties: [:first_name, :last_name, :email]]

( table items [행]은 :contacts [모든 연락처가 행을 나타냄]의 @presenter 속성에 양방향으로 데이터 바인딩되며 열은 Contact 모델 속성에 매핑됩니다: first_name , last_name 및 email )



글쎄요, 저는 테이블을 데이터 바인딩하는 동일한 한 줄의 코드가 어제 만들어진 최신 릴리스에서 훨씬 더 많은 일을 한다는 것을 발표하게 되어 기쁩니다! Glimmer DSL for SWT v4.24.3.0 에서 해당 코드 줄은 뷰 코드를 변경하지 않고 다음과 같은 추가 테이블 셀 속성도 데이터 바인딩합니다.

테이블 셀 배경색

표 셀 전경색

테이블 셀 글꼴

테이블 셀 이미지

데이터 바인딩된 테이블 행 모델(또는 Presenter)은 이제 규칙에 따라 열 속성의 이름과 일치하지만 다음 접미사 중 하나를 사용하는 메서드를 구현하여 이 데이터를 선택적으로 제공할 수 있습니다.

_background

_foreground

_font

_image

예를 들어, first_name 속성의 경우 모델은 각 모델의 테이블 행에 대한 first_name 셀의 색상을 지정된 RGB 색상. 같은 방식으로 first_name_background , first_name_foreground 및 first_name_font 도 선택적으로 구현되어 필요한 경우 추가 스타일 속성을 지정할 수 있습니다. 물론 문제를 보다 명확하게 분리하기 위해 이러한 추가 세부 정보를 제공하기 위해 모델을 둘러싸는 프리젠터를 구현하는 것이 더 좋겠지만 Glimmer DSL for SWT 소프트웨어 엔지니어의 재량에 맡깁니다.

어쨌든 Hello, Table! sample은 table 데이터 바인딩에 대한 새로운 개선 사항을 반영하도록 업데이트되었습니다. 예약된 야구 게임 테이블 셀을 흰색 전경과 기울임체 글꼴로 녹색으로 표시합니다.
