Subclass of TPointerEvent created in order to maintain binary compatibility while extending TPointerEvent with new data: (1) pointer number of the pointer whose state change is described by the event, (2) proximity of the pointer to the screen's surface, (3) pressure applied by the pointer to the screen.
These new attributes will be present only on devices that support them, otherwise they will be set to 0.

|---|---|---|
| EDefaultPointerNumber | 0 |
The value used by Symbian OS as the default pointer number for pointer-related event objects which do not contain a pointer number member. WARNING: Enum for internal use ONLY. Compatibility is not guaranteed in future releases. |
| EMaximumWServNumberOfPointers | 8 |
Maximum number of pointers that WServ is able to support. On each particular platform, the number of supported pointers must be less than or equal to this value. WARNING: Enum for internal use ONLY. Compatibility is not guaranteed in future releases. |

Gets the pointer number of the pointer whose state change is described by this event.
from this time it may be re-used to identify another pointer coming into range.
On a particular device, the pointer number is always an integer in the range 0 to HALData::EPointerNumberOfPointers - 1. If the device doesn't provide value for this attribute, it is assumed to be 1.
Please note that in order to receive events from multiple pointers in a window, the method RWindowBase::EnableAdvancedPointers() has to be called for this window's instance before it is activated. Otherwise this window will only receive TPointerEvents from one emulated pointer, which will always have pointer number 0.

| TInt | Pressure | ( | ) | const [inline] |
Gets the pressure applied by the pointer to the screen. Pressure units may vary between devices and may be non-linear. Returned value will be a positive integer as the maximum supported pressure range in Symbian OS is from 0 to KMaxTInt. HALData attributes provide more information about pressure support on particular device.
On platforms without pointer pressure support, pressure is always assumed to be 0.

| TInt | Proximity | ( | ) | const [inline] |
Gets the proximity of the pointer to the screen's surface. Proximity units may vary between devices and may be non-linear. Returned value will be a negative integer as the maximum supported proximity range in Symbian OS is from KMinTInt to 0, where KMinTInt means the highest proximity that Symbian OS can support and 0 means touching the screen. HALData attributes provide more information about proximity support on particular device.
On platforms without pointer proximity support, proximity is always assumed to be 0.

| TInt | ProximityAndPressure | ( | ) | const [inline] |
Gets pressure applied by the pointer to the screen and proximity of the pointer to the screen as one value. This is possible because the pointer is never in proximity to the screen and pressing the screen at the same time.
