Java 显示列时调整列大小-NatTable
我有一个用于列标题的Java 显示列时调整列大小-NatTable,java,swt,nattable,Java,Swt,Nattable,我有一个用于列标题的VerticalTextPainter，还有一个用于行标题的TextPainter 有些列/行有换行符，所以我想调整列宽和行高以适应内容。这只应在第一次显示列/行时发生一次，以便用户可以在之后更改宽度/高度 当滚动速度相当快时，它有时不会调整列/行的大小 nattable.addOverlayPainter(new IOverlayPainter() { @Override public void paintOverlay(final GC gc, fina
