Multicolumn sorting example (wihout native indicator support) none

Description Stefan Lötscher CLA 2006-03-24 09:43:12 EST 
Hi

There is already support for sort indicator for one column. It should be possible to have the same for multi-column sorting. The sorting order must not be visualized in table. This can be done by the otherwise.

Multicolumn sorting example (wihout native indicator support)

Visualization of multi column sort indicator not done in table itself. Order of columns in drop-down indicate the sort order.

Not sure what this is.  Is it a request for a popup menu?

No, it has nothing to do with a popup menu. The screen shot is just an example how we visualized the order of the sorting if you have more than one column sorted a the same time.

The thougt is that we need an interface on the Table class that looks as follows to support multi column  sorting with native sort indicators.

<code>
public TableColumn[] getSortColumns();
public void setSortDirection(int sortDirection, int columnIndex);
public void addSortColumn (TableColumn column);
public removeSortColumn (TableColumn column);

Ok, I understand.  VI or SSQ, which platform had the restriction that there could only be a single sort column?

Basically I agree, but I strongly suggest that at least
additional a setter

void setSortColumns(TableColumn[] columns);

is provided. This is much more powerful than add/removeColumn
and history shows that usually such a request will follow
later. Just have a look at StructuredViewer#setFilters compared
to StructuredViewer#addFilter/StructuredViewer#removeFilter.

May I ask if there is any progress on this?
