[platform-swt-dev] Table and TableViewer

[Mark Proctor <mproctor@xxxxxxxxxxxx>]

I'm doing some Table and TableViewer development as part of a Worksheet 
application.
1) How do I highlight rows/columns - or is this something I have to 
handle manually by iterating and changing the BG color of each cell?

2) if I want to make cells flash what is the best way to do this?
-Currently I have a Timer which has a HashMap of FlashRequsts(Table 
table, int col, int row) The Timer fires every 1000ms and then uses a 
asyncexec to iterate through the map and switch the colors. However on a 
really large system, 30,000-90,000 cells where only a small proportion 
are visible I'm wondering if I should add in a mechanism to determine if 
the cell is visible - especially as each flash request evaluates and 
expression to determine the cell should flash. In Jtable this mechanism 
is part of the render process where it only tries to render visible 
cells and it intercepts the renderer setting the correct bg color. If I 
should add this machanism, how would I do it?

3) This is really presnetation logic. If I'm going to extend the API for 
row/column highlighting and cell flashing; where is the correct place to 
add the methods. I have a  Worksheet (The model), 
WorksheetContentProvider (IStructuredContentProvider), 
WorksheetLabelProvider (ITableLabelProvider) , WorksheetCellModifier 
(ICellModifier). I think I should extend the Table with methods I need - 
WorksheetTable - I can probably add the boolean isVisible(TableItem 
tableItem, int index) to determine if a cell is visible or not.

3) Is it possible to only render the cell grid for populated cells?

Thanks
