enableTouchZoom

Enable or disable touch zooming.
[read/write property] enableTouchZoom([out, retval] VARIANT_BOOL *enabled) enableTouchZoom([in] VARIANT_BOOL enabled)
This property enables (if set to true) or disables (if set to false) the touch zoom event. This is only useful on a Windows system with a touch screen.

If enabled, two-finger "pinch" gestures will trigger the touchZoom event.

The default setting is enabled. Disabling touch zooming can be useful when your application is in a mode that allows selecting or highlighting text, and where zooming would be inappropriate.

IMPORTANT: Setting enableTouchZoom to true only enables the events; it does not perform any zooming. See touchZoom for more information.

VB6:
viewer.enableTouchZoom = False
