NatTable中可调整大小的行/列标题

问题描述

我有带有列和行标题的NatTable，并为其使用CornerLayer.如何使行和列标题可调整为与其他任何列或行一样的大小?

I have NatTable with column and row headers, and use CornerLayer for it. How to make row and column headers resizable like any other column or row?

推荐答案

您需要注册对标头区域的必要绑定

You need to register the necessary bindings to the header regions

gridLayer.addConfiguration(new AbstractUiBindingConfiguration() {

    @Override
    public void configureUiBindings(UiBindingRegistry uiBindingRegistry) {
        uiBindingRegistry.registerFirstMouseMoveBinding(
                new ColumnResizeEventMatcher(SWT.NONE, GridRegion.ROW_HEADER, 0),
                new ColumnResizeCursorAction());

        uiBindingRegistry.registerFirstMouseDragMode(
                new ColumnResizeEventMatcher(SWT.NONE, GridRegion.ROW_HEADER, 1),
                new ColumnResizeDragMode());

        uiBindingRegistry.registerFirstMouseMoveBinding(
                new RowResizeEventMatcher(SWT.NONE, GridRegion.COLUMN_HEADER, 0),
                new RowResizeCursorAction());

        uiBindingRegistry.registerFirstMouseDragMode(
                new RowResizeEventMatcher(SWT.NONE, GridRegion.COLUMN_HEADER, 1),
                new RowResizeDragMode());
    }
});
