= SDL_DollarGestureEvent =
A structure that contains complex gesture event information.

<<TableOfContents()>>

== Data Fields ==
||Uint32||'''type'''||SDL_DOLLARGESTURE or SDL_DOLLARRECORD||
||Uint32||'''timestamp'''||timestamp of the event||
||SDL_TouchID||'''touchId'''||the touch device id||
||SDL_GestureID||'''gestureId'''||the unique id of the closest gesture to the performed stroke||
||Uint32||'''numFingers'''||the number of fingers used to draw the stroke||
||float||'''error'''||the difference between the gesture template and the actual performed gesture (lower error is a better match)||
||float||'''x'''||the normalized center of gesture||
||float||'''y'''||the normalized center of gesture||

/* <<Color2(col=green,text="Worth changing touchId and gestureId to touchID and gestureID for consistency?")>> */

== Code Examples ==

== Remarks ==
[[SDL_DollarGestureEvent]] is a member of the [[SDL_Event]] union and is used when an event of type SDL_DOLLARGESTURE is reported.  You would access it through the event's `dgesture` field.

'''x''' and '''y''' are in range 0 to 1.

For SDL_DOLLARRECORD only '''touchId''' and '''gestureId''' are valid.
