Interface GLFWCursorPosCallbackI

  • All Superinterfaces:
    CallbackI, CallbackI.V, Pointer
    All Known Implementing Classes:
    GLFWCursorPosCallback
    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 GLFWCursorPosCallbackI
    extends CallbackI.V
    Instances of this interface may be passed to the SetCursorPosCallback method.

    Type

    
     void (*) (
         GLFWwindow *window,
         double xpos,
         double ypos
     )
    Since:
    version 3.0
    • Method Detail

      • getSignature

        default java.lang.String getSignature()
        Description copied from interface: CallbackI
        Returns the dyncall signature for this callback function. [INTERNAL API]
        Specified by:
        getSignature in interface CallbackI
        Returns:
        the dyncall signature
      • callback

        default void callback​(long args)
        Description copied from interface: CallbackI.V
        Will be called by native code.
        Specified by:
        callback in interface CallbackI.V
        Parameters:
        args - pointer to a DCArgs iterator
      • invoke

        void invoke​(long window,
                    double xpos,
                    double ypos)
        Will be called when the cursor is moved.

        The callback function receives the cursor position, measured in screen coordinates but relative to the top-left corner of the window client area. On platforms that provide it, the full sub-pixel cursor position is passed on.

        Parameters:
        window - the window that received the event
        xpos - the new cursor x-coordinate, relative to the left edge of the client area
        ypos - the new cursor y-coordinate, relative to the top edge of the client area
