1.11.2 Programming finger gestures
gesture_event tag
Note
This tag is only executed if the operating software's gesture control has been activated.
If the operating software recognizes a finger gesture, the parser provides the gesture
information in the $gestureinfo variable and executes the gesture_event tag. The variable
possesses the GestureInfoStruct data type and contains the following attributes:
Attribute Value Meaning
type 3 Pan gesture
4 Zoom out gesture
5 Tap gesture
flag 1 Scaling factor changed
2 Angle of rotation changed
state 1 Started
2 Updated
3 Completed
item_data Identification of the active control
-1 The gesture is not assigned to a control
!= -1 The gesture was executed in a control to which this
value was assigned during creation
point Position of the gesture
point.x X position of the gesture
point.y Y position of the gesture
delta Difference between the start of the gesture and the
current event
<Scaling difference> When scaling factor is changed
<Angular difference> When angle of rotation is changed
These attributes are predefined in the struct_def.xml file.
