ets and sets the configuration for enabling gesture messages and the type of this configuration.
It is impossible to disable two-finger panning and keep single finger panning. You must set the want bits for GC_PAN before you can set them for GC_PAN_WITH_SINGLE_FINGER_HORIZONTALLY or GC_PAN_WITH_SINGLE_FINGER_VERTICALLY.
An inertia vector is included in the GID_PAN message with the GF_END flag if inertia was disabled by a call to SetGestureConfig.
When you pass this structure, the dwID member contains information for a set of gestures. This determines what the other flags will mean. If you set flags for pan messages, they will be different from those flags that are set for rotation messages.
The following table indicates the various identifiers for gestures that are supported by the dwID member of the GESTURECONFIG structure. Note that setting dwID to 0 indicates that global gesture configuration flags are set.
Name

GID_ZOOM
3
Indicates configuration settings for the zoom gesture.
GID_PAN
4
Indicates the pan gesture.
GID_ROTATE
5
Indicates the rotation gesture.
GID_TWOFINGERTAP
6
Indicates the two-finger tap gesture.
GID_PRESSANDTAP
7
Indicates the press and tap gesture.
The following flags are used when dwID is set to 0.

GC_PAN
0x00000001
Indicates all pan gestures.
GC_PAN_WITH_SINGLE_FINGER_VERTICALLY
0x00000002
Indicates vertical pans with one finger.
GC_PAN_WITH_SINGLE_FINGER_HORIZONTALLY
0x00000004
Indicates horizontal pans with one finger.
GC_PAN_WITH_GUTTER
0x00000008
Limits perpendicular movement to primary direction until a threshold is reached to break out of the gutter.
GC_PAN_WITH_INERTIA
0x00000010
Indicates panning with inertia to smoothly slow when pan gestures stop.
Note Setting the GID_PAN flags in SetGestureConfig will affect the default gesture handler for panning. You should not have both dwWant and dwBlock set for the same flags; this will result in unexpected behavior. See Windows Touch Gestures for more information on panning and legacy panning support; see SetGestureConfig for examples of enabling and blocking gestures.
