Hi,
I have to create a table with 3 rows in the column header. Plus having a ColumnGroupHeaderLayer and
ColumnGroupGroupHeaderLayer.
I imagine the ColumnHeaderLayer shall display 3 rows.
What I did so far:
I implement a ColHeaderDataProvider and getRowCount() return 3.
See the attached picture for the result.
Unfortunately it is still only one row in the column header but not 3.
How to implement the desired behavior?
Martin

The grouping is OK in row 0 and 1 of the column header.
Row 2 of the column header is also OK (Name, Type, 9,10,11,0,1,.....)
Furthermore I want a row 3 and 4 of the column header without grouping, just like in row 2 of the
column header.

Thanks Dirk,
Yes the data provider provides data for all 3 rows but only row 0 get called. May be there is an
error in ColumnHeaderLayerStack?
here the code:
public ColumnHeaderLayerStack(IDataProvider dataProvider, BodyLayerStack pBodyLayer) {
DataLayer dataLayer = new DataLayer(dataProvider);
colHeaderLayer = new ColumnHeaderLayer(dataLayer, pBodyLayer, pBodyLayer.getSelectionLayer());
ColumnGroupModel columnGroupModelTrack = new ColumnGroupModel();
columnGroupHeaderLayerTrack = new ColumnGroupHeaderLayer(colHeaderLayer,
pBodyLayer.getSelectionLayer(), columnGroupModelTrack);
columnGroupHeaderLayerTrack.addColumnsIndexesToGroup("Track", 0, 1);
ColumnGroupModel columnGroupModelLine = new ColumnGroupModel();
columnGroupHeaderLayerLine = new ColumnGroupGroupHeaderLayer(columnGroupHeaderLayerTrack,
pBodyLayer.getSelectionLayer(),
columnGroupModelLine);
columnGroupHeaderLayerLine.addColumnsIndexesToGroup("Line", 0, 1);
}
Does this give you any hints of an error?
