Sadly, not all of us can drive across country to get to WWDC :-\ I am upgrading an app to use bindings (I can see I will eliminate a ton of code, yeah!). I try to bind the window title using a Title with Pattern to include an attribute from an object in the window. If I update said attribute, the window title updates nicely. However, when the window first appears, it has the default window title (i.e. the document title). I even tried putting [self synchronizeWindowTitleWithDocumentName] in windowDidLoad but it has no effect. The only way I can make it work is to also override windowTitleForDocumentDisplayName:. Is there something I am missing?
OK, two stabs at this... 1 - If your window's bound value is null you should bind the "NULL Placeholder", might consider binding the "No Selection" value also.
2 - When you change your window's bound value programmatically you should use the following, um.. structure....can't think of the word right now.
[owningObject willChangeValueForKey:@"windowBoundValueKey"]; // Change value here [owningObject didChangeValueForKey:@"windowBoundValueKey"];
Hope that helps, Lee |
