I would appreciate any help with the following conundrum-
I have the following classes:
General/CustomView CustomWindow1 CustomWindow2 General/DealWithData
here’s the scenario:
General/DealWithData is the primary class and contains methods for setting the alpha of CustomWindow2
CustomWindow1 is an General/NSWindow that is connected to General/DealWithData by an General/IBOutlet - it is the original window from the original NIB created when I began this cocoa app (I suspect this is significant)
CustomWindow1 contains General/CustomView, which is registered for drags General/CustomView can reference the methods in General/DealWithData through a singleton instance of General/DealWithData
CustomWindow2 is an General/NSWindow that is also connected to General/DealWithData by its own General/IBOutlet CustomWindow2 contains some textviews and other data
What I want is for the calls in General/DealWithData that control window opacity of CustomWindow2 to be activated by a drag event in General/CustomView (which is contained in CustomWindow1).
So what I am doing is as follows: from within General/CustomView, I get the singleton instance of General/DealWithData, and when I get drag events I call [instanceOfDealWithData changeWindowOpacityOfWIndowTwo]
strangely, the events in General/DealWIthData are in fact called (because I have General/NSLogs that get triggered), but the opacity of CustomWindow2 is unchanged. If I create buttons in CustomWindow1 with actions to call those very same functions that were ostensibly called by the drag event, then the opacity changes!
sounds like this problem:
nope, it was a problem with my implementation of the Singleton. First time singleton users: read the entire thread before using it to make sure you understand what is going on. Don’t forget to override -(init) to establish a static instance right off the bat!
