I need to be able to modify the behavior of my tableview. When I click on a row, i would like it to be selected but show now signs of being selected. I may in the future want to just draw a frame around the selected row - but for now I would just like it to do nothing. In other words I want to disable the blue highliting when a cell is clicked. The row does need to be selectable however because the cells are editable and one of the columns consists of NSPopUpButtonCells. I have subclassed NSTableView and NSTableColumn. Help with this would make my week! Thanks in advance.
