      • TOUCHINPUT

        public TOUCHINPUT​(java.nio.ByteBuffer container)
        Creates a TOUCHINPUT instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.

    • Method Detail

      • sizeof

        public int sizeof()
        Specified by:
        sizeof in class org.lwjgl.system.Struct

      • x

        public int x()
        the x-coordinate (horizontal point) of the touch input. This member is indicated in hundredths of a pixel of physical screen coordinates.

      • y

        public int y()
        the y-coordinate (vertical point) of the touch input. This member is indicated in hundredths of a pixel of physical screen coordinates.

      • hSource

        public long hSource()
        a device handle for the source input device. Each device is given a unique provider at run time by the touch input provider.

      • dwID

        public int dwID()
        a touch point identifier that distinguishes a particular touch input. This value stays consistent in a touch contact sequence from the point a contact comes down until it comes back up. An ID may be reused later for subsequent contacts.

      • dwFlags

        public int dwFlags()
        a set of bit flags that specify various aspects of touch point press, release, and motion. The bits in this member can be any reasonable combination of the values in the Remarks section.

      • dwMask

        public int dwMask()
        a set of bit flags that specify which of the optional fields in the structure contain valid values. The availability of valid information in the optional fields is device-specific. Applications should use an optional field value only when the corresponding bit is set in dwMask. This field may contain a combination of the dwMask flags mentioned in the Remarks section.

      • dwTime

        public int dwTime()
        the time stamp for the event, in milliseconds. The consuming application should note that the system performs no validation on this field; when the User32.TOUCHINPUTMASKF_TIMEFROMSYSTEM flag is not set, the accuracy and sequencing of values in this field are completely dependent on the touch input provider.

      • dwExtraInfo

        public long dwExtraInfo()
        an additional value associated with the touch event.

      • cxContact

        public int cxContact()
        the width of the touch contact area in hundredths of a pixel in physical screen coordinates. This value is only valid if the dwMask member has the User32.TOUCHINPUTMASKF_CONTACTAREA flag set.

      • cyContact

        public int cyContact()
        the height of the touch contact area in hundredths of a pixel in physical screen coordinates. This value is only valid if the dwMask member has the User32.TOUCHINPUTMASKF_CONTACTAREA flag set.

        public static TOUCHINPUT malloc()
