如何在不使用选择层以外的任何层的情况下冻结可移植的任何列

Question

I have added DragDetectListener and run doCommand in that. It gives true result but column doesn't gets freeze. my code is :

natTable.addDragDetectListener(new DragDetectListener() {
    @Override
    public void dragDetected(DragDetectEvent paramDragDetectEvent) {
        boolean b = natTable.doCommand(new FreezeColumnCommand(glazedListsGridLayer.getcompositeFreezeLayer(), 0));
    }
});

Adding code of layer stack :

bodyDataLayer = new DataLayer(bodyDataProvider);
        GlazedListsEventLayer<IzSearchResultRowData> glazedListsEventLayer = new GlazedListsEventLayer<IzSearchResultRowData>(bodyDataLayer, eventList);
        bodyLayer = new DefaultBodyLayerStack(glazedListsEventLayer);
        ColumnOverrideLabelAccumulator bodyLabelAccumulator = new ColumnOverrideLabelAccumulator(bodyDataLayer);
        bodyDataLayer.setConfigLabelAccumulator(bodyLabelAccumulator);
        // Column header layer
        selectionLayer = bodyLayer.getSelectionLayer();
        DataLayer columnHeaderDataLayer = new DefaultColumnHeaderDataLayer(bulkDataManager);
        columnHeaderDataLayer.setRowHeightByPosition(0, 35);
        final FreezeLayer freezeLayer = new FreezeLayer(selectionLayer);
        final CompositeFreezeLayer compositeFreezeLayer = new CompositeFreezeLayer(
                freezeLayer, bodyLayer.getViewportLayer(), selectionLayer);
        ColumnHeaderLayer columnHeaderLayer = new ColumnHeaderLayer(columnHeaderDataLayer, compositeFreezeLayer, selectionLayer);

Another Thing : I am getting position coordinates through selection layer. when i am running freeze command as natTable.doCommand(new FreezeColumnCommand(glazedListsGridLayer.getSelectionLayer(), 0));

Its giving false result.

Hard to tell without seeing your layer stack. Maybe you have a more complicated layer composition and the command is lost on the way because of the index-position-transformation. Try to execute the command on the layer for which you provide the position coordinates.

natTable.addDragDetectListener(new DragDetectListener() {
    @Override
    public void dragDetected(DragDetectEvent paramDragDetectEvent) {
        boolean b = glazedListsGridLayer.getcompositeFreezeLayer().doCommand(
            new FreezeColumnCommand(glazedListsGridLayer.getcompositeFreezeLayer(), 0));
    }
});
