public Class WGLEXTSwapControl

extends Object
Class Inheritance
Imports
org.lwjgl.system.*
Native bindings to the WGL_EXT_swap_control extension.

This extension allows an application to specify a minimum periodicity of color buffer swaps, measured in video frame periods.

Requires WGL_EXT_extensions_string.

public static int wglGetSwapIntervalEXT()

Returns the current swap interval for the window associated with the current context.

wglSwapIntervalEXTback to summary
public static boolean wglSwapIntervalEXT(int interval)

Specifies the minimum number of video frame periods per buffer swap for the window associated with the current context. The interval takes effect when org.lwjgl.system.windows.GDI32#SwapBuffers or wglSwapLayerBuffer is first called subsequent to the wglSwapIntervalEXT call.

A video frame period is the time required by the monitor to display a full frame of video data. In the case of an interlaced monitor, this is typically the time required to display both the even and odd fields of a frame of video data. An interval set to a value of 2 means that the color buffers will be swapped at most every other video frame.

If interval is set to a value of 0, buffer swaps are not synchronized to a video frame. The interval value is silently clamped to the maximum implementation-dependent value supported before being stored.

The swap interval is not part of the render context state. It cannot be pushed or popped. The default swap interval is 1.

Parameters
interval:int

the minimum number of video frames that are displayed before a buffer swap will occur
