Table with no row header [message #1066823]

Hello,

I'm trying to create a table which doesn't have a row header (so simply a column header and a data section). I initially started with a GridLayer, but this layer always display the row header.

So, I changed to a CompositeLayer and created the column layer and body layer, but now my table is not editable anymore (which was the case when using a gridLayer).

Here is a code snippet:

		EventPropertyBodyLayerStack bodyLayer = new EventPropertyBodyLayerStack(
				eventType.getProperties(), propertyNames);

		// Column header
		DefaultColumnHeaderDataProvider columnHeaderDataProvider = new DefaultColumnHeaderDataProvider(
				propertyNames, propertyToLabelMap);
		ILayer columnHeaderLayer = new ColumnHeaderLayer(
				new DefaultColumnHeaderDataLayer(columnHeaderDataProvider),
				bodyLayer, bodyLayer.getSelectionLayer());

		CompositeLayer compositeLayer = new CompositeLayer(1, 2);
		compositeLayer.setChildLayer(GridRegion.BODY, bodyLayer, 0, 1);
		compositeLayer.setChildLayer(GridRegion.COLUMN_HEADER,
				columnHeaderLayer, 0, 0);

		final ColumnOverrideLabelAccumulator columnLabelAccumulator = new ColumnOverrideLabelAccumulator(
				bodyLayer.getDataLayer());
		bodyLayer.getDataLayer().setConfigLabelAccumulator(
				columnLabelAccumulator);
		registerColumnLabels(columnLabelAccumulator);

		IConfigRegistry configRegistry = new ConfigRegistry();
		natTable = new NatTable(this, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL,
				compositeLayer, false);
		natTable.setConfigRegistry(configRegistry);
		natTable.addConfiguration(new DefaultNatTableStyleConfiguration());
		natTable.addConfiguration(new EventPropertyEditConfiguration());
		natTable.configure();

Any idea what I might be doing wrong ? If some additional code is needed, I can provide it.

Thank you,
Cédric

Have you ensured that the edit binding configurations are added in your edit configuration?

Yes, I'm pretty sure that this is correct, since if I replace the code with my previous code (which was creating a grid layer instead), then it works fine.
I didn't touch anything in the registerColumnLabels method and the EventPropertyEditConfiguration class.

I had a look at the GridLayer to see what it did and I saw that there was this piece of code which overrides the CompositeLayer behavior:

	@Override
	protected boolean doCommandOnChildLayers(ILayerCommand command) {
		if (doCommandOnChildLayer(command, getBodyLayer())) {
			return true;
		} else if (doCommandOnChildLayer(command, getColumnHeaderLayer())) {
			return true;
		} else if (doCommandOnChildLayer(command, getRowHeaderLayer())) {
			return true;
		} else {
			return doCommandOnChildLayer(command, getCornerLayer());
		}
	}
	
	private boolean doCommandOnChildLayer(ILayerCommand command, ILayer childLayer) {
		ILayerCommand childCommand = command.cloneCommand();
		return childLayer.doCommand(childCommand);
	}

Is this maybe related to the problem ? I tried to implement the same functionality in my case by it still didn't work.

Again, are you sure that the DefaultEditBindings are included in your edit configuration? By default it is added in the DefaultGridLayerConfiguration, which you don't have as you don't use the GridLayer. So if you don't add it manually, it wouldn't be there!

Hello Dirk,

Sorry for my beginner questions, I just started to use the control, so I'm sometimes a bit lost...

Ok, I misunderstood your previous reply, I thought that you were talking about the way to configure the edit properties like shown in the examples (specifying which columns are editable, adding combobox cell editors, ...).

Indeed, I didn't do that. So, now if I add that configuration (in fact I add DefaultEditBindings and DefaultEditConfiguration) to my CompositeLayer, I can edit my fields in the table. However the selection is now behaving in a very strange way: it always disappear. So if I edit a cell and conform (for instance by hitting enter), then the cell selection disappear (which means I can't navigate my table using keyboard anymore).

Here is what I do:

		CompositeLayer compositeLayer = new CompositeLayer(1, 2);
		compositeLayer.setChildLayer(GridRegion.COLUMN_HEADER,
				columnHeaderLayer, 0, 0);
		compositeLayer.setChildLayer(GridRegion.BODY, bodyLayer, 0, 1);
		compositeLayer.addConfiguration(new DefaultEditBindings());
		compositeLayer.addConfiguration(new DefaultEditConfiguration());

Do I add the configurations on the correct layer ?

Yes it should be the correct layer. Not sure what happens on commit. Are you doing some special stuff on commit? Is the NatTable refreshed or does it lose focus on commit?

Oh yes, I have a listener on my model which refreshes the table when the model changes (this allows undo/redo for instance). I'll have to find another way of doing that.

Thanks for the help !
