performance performance and performance

-
Touch and Gesture support in framework
-
Metro app with HTML or XAML—> Gesture event
-
ICoreWindow –> Using point (touch simulate mouse click)
-
Windows Runtime –> PointerPoint with GestureRecognizer
-
-
PointerPoint:
- Whole related point implement is here, HID data also can get using PointerPoint.
-
GestureRecognizer:
-
It just like the Win7 multiple touch support on MSFT, it support kind of gesture such as:
- Tap, Hold, rotate and Scale
-
But more support on Win8 such as:
-
HoldWithMouse?
-
RightTap
-
To simulate with right click on mouse, such your finger about right click here.
-
mmmm….. it should be MSFT patent here for right click.
-

-
For desktop developer, MSFT also support full Windows Runtime about Gesture support –> Great!
-
WM_Point –> the same as usual
-
InteractionContexts –> mirror GestureRecognizer. Don’t forget WM_TOUCH and WM_GESTURE still support here.
-
Pointer device –> identify source device (touch panel, mouse or other.)
