Hi,

Please ignore the first email sent by me. I sent it out by mistake.a

I write a custom class which has two NSPopupButtonCells.

The interface looks like this:

@interface CustomCellArray:NSCell

{

NSMutableArray * cells;

}

@end

in this array cells, it contains two NSPopupButtonCells. I embed this custom cell CustomCellArray in the column B of a NSTableView.

It works well to show the two NSPopupButtonCells, and respond to the mouse events.

But I have problems when add accessibility support for this kind of custom cell.

I override the NSTalbeView's - (id)accessibilityHitTest:(NSPoint)point like this. the uiElements is an array hosted in the NSTableView. the FauxUIElement has adopted the NSAccessibility protocol.

- (id)accessibilityHitTest:(NSPoint)point
{
id result = [super accessibilityHitTest:point];
NSPoint windowPoint = [[self window] convertScreenToBase:point];
NSPoint localPoint = [self convertPoint:windowPoint fromView:nil];
NSInteger row = [self rowAtPoint:localPoint];
NSInteger col = [self columnAtPoint:localPoint];

if(col == 1 &&row >= 0) //hit the valid row and the customized column
{
      if(uiElements == nil)
      {
           FauxUIElement * ele1 = [FauxUIElement elementWithRole:NSAccessibilityPopUpButtonRole parent: self];
           FauxUIElement * ele2 = [FauxUIElement elementWithRole:NSAccessibilityPopUpButtonRole parent: self];
           uiElements = [[NSArray alloc] initWithObjects:ele1, ele2, nil];
      }
      NSRect cellFrame = [self frameOfCellAtColumn:col row: row];
      NSRect cell1 = cellFrame;
      cell1.size.width = cellFrame.size.width * 0.6;
      NSRect cell2 = cellFrame;
      cell2.origin.x = cell1.origin.x + cell1.size.width;
      cell2.size.width = cellFrame.size.width * 0.4;

    if(NSPointInRect(localPoint, cell1))   //check whether it hits the first popupcell or the second one.
           return [uiElements objectAtIndex:0];
      else if(NSPointInRect(localPoint, cell2))
           return [uiElements objectAtIndex:1];
}

return result;
}

But when I use the accessibility inspector to check it. the two cells are marked as AXUnknown.

I also wonder is it a right place to override the accessiblityHitTest in NSTableView to achieve this?

Any suggestions?

Thanks.
