Hi,

I'm having a problem with a subclass of NSTableRowView I'm trying to implement. 
I have custom NSTableCellView that contains a button. When I press the button, 
I want that row to expand in height. I would like to then place a custom NSView 
into that new space (think of it as a detail view of the cell that was clicked).

I created an NSTableRowView subclass, but currently have no custom code (except 
to trap mouse events and immediately call "super" with them). When the button 
is clicked, I add my custom view as a subview of my custom NSTableRowView, and 
it appears. The problem is that this custom view does not see any mouse events. 
As a simple test, I placed a slider control into the view, but I can't move it.

Stepping through the debugger, I see that my NSTableRowView subclass is indeed 
being used, that it contains no other subviews than all of the NSTableRowView 
instances for each column plus the one I manually added. I put an NSLog 
statement in the NSTableRowView's mouseDown method, but no mouse downs are 
being recorded in the open space created by updating the height of the table. I 
have called "noteHeightOfRowsWithIndexesChanged" when making these changes.

Where are the mouse clicks going!?? This is driving me batty.

Cheers,
Demitri
