I have the following issue. I am trying to reproduce an XCode-like "new project" workflow in a small IDE I build. For this I have a sheet that runs modal in the window created by the doc window controller when user selects "New project". The sheet is inited from a nib and loads several subviews (via view controllers) in a stepwise approach, to set up the project (type -> parameters ... etc) to the point of saving the new project. So far so good.
The problem I have is when I try to cancel the process BEFORE saving. I cannot figure how to close the modal sheet and the doc instance WITHOUT closing other doc instances (aka "projects") that might be opened.
My app has a delegate, a NSDocument class that is controlled via a NSWindowController and several other controllers and nibs. For now, I am thinking of implementing a notification-based approach in the application delegate, but I cannot get to a grip.
I would appreciate if you could point me in the right direction.
Warmest regards,
Tom
You could also call an action method when the cancel button is pressed. This way the action method manages to close the sheet and close your NSDocument subclass instance.
