Is it possible to insert/remove table columns dynamically in BIRT? [message #99026]

Hi,

Im trying ( BIRT 1.0.1) to insert columns to a table dynamically, but I
can not find the right method in the APIs.

Is it possible to insert/remove table columns dynamically in BIRT?
If yes how to do that?

Thanks,

Said

I believe you would have to use the Report Engine API which has a handle to
the report desgin.
You would take the handle load the Report using the DE API modify the table
and then reload it in the Engine. This could be done all in memory using
the engine.openReportDesign( InputStream) method.

In order to modify the table Im using this:
// add a new column to table
ColumnHandle colH = table.getElementFactory().newTableColumn();

TableHandle item = table.getElementFactory().newTableItem("tableItem", 3);

Further there is no method in TableHandle object that can add a new
column.

Can you give an example how to do this please?

Try doing this

TableHandle th = factory.newTableItem("test",2);
SlotHandle slot = th.getColumns();
ColumnHandle ch = factory.newTableColumn();
slot.add(ch);
design.getBody().add( th);

The following code creates a new table with two columns instead of add a
column to the existing table.

TableHandle th = factory.newTableItem("test",2);
SlotHandle slot = th.getColumns();
ColumnHandle ch = factory.newTableColumn();
slot.add(ch);
design.getBody().add( th);

What I try to do is this:

table1:
----------------------------
| col1 | col2 |
| | |
---------------------------

add col3 to tabl1:
------------------------------------
| col1 | col2 | col3 |
| | | |
------------------------------------

remove col3 from table1:
----------------------------
| col1 | col2 |
| | |
---------------------------

Thanks,
Said

Adding and Deleting Columns requires worrying about groups and the number of
rows.
I was able to get this to work using the TableHandleAdapter class, which is
used by the GUI.
Might not be the right thing to do, but here is a snippet.

//name of my table
TableHandle th = (TableHandle)design.findElement("test");
TableHandlerAdapter hta = new TableHandleAdapter( th, null);
tha.insertColumn(1, 1);

or

tha.deleteColumn(1);

The class TableHandleAdapter consists of insert/delete column, but it is
not included in the APIs.

How can I use it in mine application?

Thanks,

Said

Said,

If you download the source you can look at the TableHandleAdapter class.
I used it by importing it

import
org.eclipse.birt.report.designer.core.model.schematic.TableH andleAdapter

It is in core.jar.
