[SOLVED] Problem with ColumGroupHeaderLayer and SortHeaderLayer [message #1062217]

Hi,

I just migrated from NatTable SF-2.3.1 to the new Nebula 1.0.0 release.

Now, when sorting the first column in a ColumnGroup, the sort icon gets painted on the GroupHeader as well (see screenshot - unfortunately i can't include the image in the post directly).

The problem seems to be SortHeaderLayer#getConfigLabelsByPosition which also adds the "SORT_UP"-Label to the GroupHeader.

My configuration is:

columnHeaderLayer = new ColumnHeaderLayer(columnHeaderDataLayer, bodyLayer, selectionLayer, false);
columnHeaderLayer.addConfiguration(new MyColumnHeaderLayerConfiguration());
columnGroupHeaderLayer = new ColumnGroupHeaderLayer(columnHeaderLayer, selectionLayer, columnGroupModel,false);
columnGroupHeaderLayer.addConfiguration(new MyColumnGroupHeaderLayerConfiguration(columnGroupModel));
sortableColumnHeaderLayer = new SortHeaderLayer<T>(columnGroupHeaderLayer, sortModel, false);

I tried a different ordering of ther layers, but with any different order the ColumnGroupHeader dissapears. Anyone has an idea what i am doing wrong?

Hi,

have you tried the following layer composition?

ColumnHeaderLayer
SortHeaderLayer
ColumnGroupHeaderLayer

This way the label should be only applied to the cells in the ColumnHeaderLayer as the SortHeaderLayer is not aware of the ColumnGroupHeaderLayer.

Hi,

thank you for your quick reply. Unfortunately, I tried this composition already. Then the ColumnGroup is not painted anymore. The ColumnGroupHeaderLayer constructor expects a ColumnHeaderLayer so I suspect that inserting a SortHeaderLayer in between isn't supported. I also tried composing both the SortHeaderLayer and the ColumnGroupHeaderLayer on top of the ColumnHeaderLayer (i.e parallel), but that does not work either.

For the time being I just subclassed the SortHeaderLayer overriding getConfigLabelsByPosition:

public LabelStack getConfigLabelsByPosition(int columnPosition, int rowPosition) {

LabelStack underlyingLabelStack = getUnderlyingLayer().getConfigLabelsByPosition(columnPosition, rowPosition);

if (underlyingLabelStack.hasLabel(GridRegion.COLUMN_GROUP_HEADER)) {
	return underlyingLabelStack;
}

return super.getConfigLabelsByPosition(columnPosition, rowPosition);
}

That's wrong! The ColumnGroupHeaderLayer constructor expects an ILayer as underlying layer. The parameter is named columnHeaderLayer which leads to missinterpretion!

Of course this isn't working because the layers are stacked!

When I'm building my layer stack up like following, everything works as expected:

DefaultColumnHeaderDataLayer dataLayer = new DefaultColumnHeaderDataLayer(dataProvider);
ColumnHeaderLayer columnHeaderLayer = new ColumnHeaderLayer(dataLayer, bodyLayerStack, bodyLayerStack.getSelectionLayer());

SortHeaderLayer<T> sortHeaderLayer = new SortHeaderLayer<T>(
	columnHeaderLayer, 
	new GlazedListsSortModel<T>(
		bodyLayerStack.sortedList, 
		columnPropertyAccessor,
		configRegistry, 
		dataLayer), 
	false);

ColumnGroupHeaderLayer columnGroupHeaderLayer = new ColumnGroupHeaderLayer(
		sortHeaderLayer, bodyLayerStack.selectionLayer, model);

Of course in the code above I register the SingleClickSortConfiguration() aswell:

natTable.addConfiguration(new SingleClickSortConfiguration());

I just inspected my code some more and found that the FilterRowHeaderComposite registered on top of the SortHeaderLayer. So even when I tried your suggested composition, the FilterRowHeaderComposite would register on top of the SortHeaderLayer an thus disabling the ColumnGroupHeaderLayer. Thanks for your patience and pointing me in the right direction.
