Members
| Member name | Description | |
|---|---|---|
| AllGestures | Recognizes all application-specific gestures. | |
| NoGesture | Recognizes no application-specific gestures. | |
| Scratchout | This gesture must be drawn as a single stroke that has at least three back-and-forth motions. | |
| Triangle | The triangle must be drawn in a single stroke, without lifting the pen. | |
| Square | The square can be drawn in one or two strokes. In one stroke, draw the entire square without lifting the pen. In two strokes, draw three sides of the square and use another stroke to draw the remaining side. Do not use more than two strokes to draw the square. | |
| Star | The star must have exactly five points and be drawn in a single stroke without lifting the pen. | |
| Check | The upward stroke must be twice as long as the smaller downward stroke. | |
| Curlicue | Start the curlicue where you want an action to occur. | |
| DoubleCurlicue | Start the double-curlicue where you want an action to occur. | |
| Circle | The circle must be drawn in a single stroke without lifting the pen. | |
| DoubleCircle | The two circles must overlap each other and be drawn in a single stroke without lifting the pen. | |
| SemiCircleLeft | The semicircle must be drawn from left to right. The two ends of the semicircle should be as horizontally even as possible. | |
| SemiCircleRight | The semicircle must be drawn from right to left. The two ends of the semicircle should be as horizontally even as possible. | |
| ChevronUp | Both sides of the chevron must be drawn as equal as possible. The angle must be sharp and end in a point. | |
| ChevronDown | Both sides of the chevron must be drawn as equal as possible. The angle must be sharp and end in a point. | |
| ChevronLeft | Both sides of the chevron must be drawn as equal as possible. The angle must be sharp and end in a point. | |
| ChevronRight | Both sides of the chevron must be drawn as equal as possible. The angle must be sharp and end in a point. | |
| ArrowUp | The arrow can be drawn in single stroke or in two strokes where one stroke is the line and the other is the arrow head. Do not use more than two strokes to draw the arrow. | |
| ArrowDown | The arrow can be drawn in a single stroke or in two strokes where one stroke is the line and the other is the arrow head. Do not use more than two strokes to draw the arrow. | |
| ArrowLeft | The arrow can be drawn in a single stroke or in two strokes where one stroke is the line and the other is the arrow head. Do not use more than two strokes to draw the arrow. | |
| ArrowRight | The arrow can be drawn in a single stroke or in two strokes where one stroke is the line and the other is the arrow head. Do not use more than two strokes to draw the arrow. | |
| Up | This gesture must be drawn as a single fast flick in the upward direction.
This gesture is used by Flicks Gestures. |
|
| Down | This gesture must be drawn as a single fast flick downward.
This gesture is used by Flicks Gestures. |
|
| Left | This gesture must be drawn as a single fast flick to the left.
This gesture is used by Flicks Gestures. |
|
| Right | This gesture must be drawn as a single fast flick to the right.
This gesture is used by Flicks Gestures. |
|
| UpDown | This gesture must be drawn in a single stroke starting with the up stroke. The two strokes must be as close to each other as possible. | |
| DownUp | This gesture must be drawn in a single stroke starting with the down stroke. The two strokes must be as close to each other as possible. | |
| LeftRight | This gesture must be drawn in a single stroke starting with the left stroke. The two strokes must be as close to each other as possible. | |
| RightLeft | This gesture must be drawn in a single stroke starting with the right stroke. The two strokes must be as close to each other as possible. | |
| UpLeftLong | This gesture must be drawn in a single stroke starting with the up stroke. The left stroke must be about twice as long as the up stroke, and the two strokes must be at a right angle. | |
| UpRightLong | This gesture must be drawn in a single stroke starting with the up stroke. The right stroke must be about twice as long as the up stroke, and the two strokes must be at a right angle. | |
| DownLeftLong | This gesture must be drawn in a single stroke starting with the down stroke. The left stroke is about twice as long as the up stroke, and the two strokes must be at a right angle. | |
| DownRightLong | Signifies pressing the spacebar. This gesture must be drawn in a single stroke starting with the down stroke. The right stroke must be about twice as long as the up stroke, and the two strokes must be at a right angle. | |
| UpLeft | This gesture must be drawn in a single stroke starting with the up stroke. The two sides must be as equal in length as possible and at a right angle. | |
| UpRight | This gesture must be drawn in a single stroke starting with the up stroke. The two sides must be as equal in length as possible and at a right angle. | |
| DownLeft | This gesture must be drawn in a single stroke starting with the down stroke. The two sides must be as equal in length as possible and at a right angle. | |
| DownRight | This gesture must be drawn in a single stroke starting with the down stroke. The two sides must be as equal in length as possible and at a right angle. | |
| LeftUp | This gesture must be drawn in a single stroke starting with the left stroke. The two sides must be as equal in length as possible and at a right angle. | |
| LeftDown | This gesture must be drawn in a single stroke starting with the left stroke. The two sides are as equal in length as possible and at a right angle. | |
| RightUp | This gesture must be drawn in a single stroke starting with the right stroke. The two sides must be as equal in length as possible and at a right angle. | |
| RightDown | This gesture must be drawn in a single stroke starting with the right stroke. The two sides must be as equal in length as possible and at a right angle. | |
| Exclamation | The line must be drawn first and then the dot drawn quickly and as close to the line as possible. | |
| Tap | Signifies a mouse click. For the least amount of slippage, tap quickly. | |
| DoubleTap | Signifies a mouse double-click. Tap quickly and in as close to the same place for best results. |
Remarks
Application gestures are gestures you can choose to have your application support. Applications that are specifically designed to work with a pen are more likely to use these gestures. For a list containing the shapes of the gestures and their suggested semantic behavior in an application, see Application Gestures and Semantic Behavior.
The Tap and DoubleTap gestures are supported as application gestures and system gestures (system gestures are defined in the SystemGesture enumeration type). This means you can incorporate an application gesture that has a component that may be construed as a Tap or DoubleTap (such as the Exclamation gesture). In this case, enable the Tap application gesture and disable the Tap system gesture in your application. When a user taps, the application gesture is recognized. This allows your application to listen for a single component that can both identify and distinguish a Tap from a Tap within the application gesture.
In addition to the following gestures, Microsoft intends to support many gesture glyphs as part of the Microsoft gesture recognizer. For more information about these unimplemented gesture glyphs, see Unimplemented Glyphs.
For more information about application gestures and system gestures, see Using Gestures.
The default value is NoGesture, which is actually a cutoff line that represents the gesture recognizer's minimum suggested confidence. It does not actually represent a gesture or lack of gesture, just the point at which the gesture recognizer lacks enough confidence in the result accuracy to recommend anything below that point.
For example, assume that a gesture array consists of the following values: Circle, LeftRight, NoGesture, RightLeft, and Triangle. In this case, the gesture recognizer has a great degree of confidence in Circle and less confidence in LeftRight. The recognizer has very low confidence in RightLeft and Triangle because they come after NoGesture in the array order.
The confidence level at which the gesture recognizer returns NoGesture cannot be changed.
If NoGesture is the first element in the array (which means every recognized gesture is below the suggested confidence threshold), then the platform cancels the gesture event by default; otherwise, the platform accepts the gesture by default. To alter the default behavior, capture the InkCollector.Gesture, InkOverlay.Gesture, InkPicture.Gesture, or InkEdit.Gesture event. When a gesture is accepted, the stroke is not added to the Microsoft.Ink.Ink object. When a gesture is canceled, the stroke is added to the Microsoft.Ink.Ink object.
