Hi everyone, I have an NSPredicateEditor, with some standard row templates. I'd like to add a custom row template with three views: a popup button (indicating the attributes this template references), a second popup button (with the operators), and a third popup button that's populated with a list of possible values.
This is very similar to a regular row template, except that the list of possible values is computed at runtime and can change periodically based on system events. I've tried subclassing NSPredicateEditorRowTemplate, overriding -templateViews, and returning my 3 popup buttons (all properly populated). This works once, but after the row is created, I haven't been able to figure out how to repopulate the popup button when the list of possible values changes. I've tried setting the popup button's menu's delegate to an object that will repopulate it, but the delegate methods are never called. I've also seen that when there's only one possible value, my popup button is replaced with a textfield. I suppose that's OK, except that if the list of possible values changes, I need that textfield to change to a popup button. How can I achieve my dynamic popup button in an NSPredicateEditorRowTemplate? Thanks! Dave DeLong
