//
// This is a bit of a trick: The Cells in the NSOutlineView bind to the "objectRef" property of TreeNode,
// and their NSTextFieldCell instances have different `tag` values set (first col is 0, the other is 1).
// This function below gets called when the NSCell is set up, and it gets the bound value passed here,
// i.e. the value from TreeNode.objectRef, which is the TreeNode itself. We then pass it to our
// SSDPDocument class which can decide which string to assign to this NSCell's objectValue.
//
- (void)setObjectValue:(id)objectValue {
	if ([objectValue isKindOfClass:TreeNode.class]) {
		// we want to replace the string with an attributed string if there's a search filter set
		id docHandler = self.controlView.window.delegate;	// we blindly assume this is of the SSDPDocument type
		objectValue = [(SSDPDocument*)docHandler highlightedObjectValue:self node:objectValue];
	}
	super.objectValue = objectValue;
