voidwindowDidResizeNSNotification

voidwindowDidR... appears to be a concatenation of a C-style void return type with a likely window-related callback name. It is not a standard, widely recognized API by itself, but it illustrates a common pattern in event-driven GUI programming: a function that returns no value and handles a window event.

In GUI frameworks, window event callbacks are used to respond to changes in window state or user actions. Such callbacks are typically invoked by the system or the framework when a specific event occurs, such as resizing, moving, focusing, or closing a window. The void return type indicates that these handlers do not compute or return a value to the caller; instead, they perform side effects like updating the user interface or persisting state.

Naming and signatures for these callbacks vary by language and framework. A typical convention is to include a window-related descriptor in the function name, such as windowDidResize or windowWillClose. Parameters often include a reference to the window and details about the event (e.g., new size or position). Examples in different languages might be: in C/C++, void windowDidResize(Window* w, int width, int height); in Objective-C, - (void)windowDidResize:(NSNotification*)note; in Swift, func windowDidResize(_ window: UIWindow, to size: CGSize).

Usage generally involves registering the callback with a window object or event dispatcher, either by implementing a delegate/protocol or by assigning a function pointer. Inside the handler, a program may adjust layouts, save state, or trigger related updates. While "voidwindowDidR..." is not a standard API, the underlying concept—a void-returning callback that handles a window event—is a common one across many GUI environments.
