Package overrungl.glfw

Interface IGLFWWindowSizeFun

All Superinterfaces:

Callback

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface IGLFWWindowSizeFun
extends Callback

IGLFWWindowSizeFun relies on preview features of the Java platform:

• IGLFWWindowSizeFun refers to one or more preview APIs: FunctionDescriptor, MemorySegment.

Programs can only use IGLFWWindowSizeFun when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

This is the function pointer type for window size callbacks. A window size callback function has the following signature:

@Invoker(IGLFWWindowSizeFun::invoke)
void callbackName(MemorySegment window, int width, int height);

Since:

0.1.0

Finds the method handle from the given method handles lookup.

Specified by:

handle in interface Callback

Parameters:

lookup - the lookup
