AutoScrollMethod Property

Description

Enables the viewer's automatic mouse pan/scroll and mousewheel zoom.

Property type

A mcAutoScrollMethods enumeration.

Syntax

object.AutoScrollMethod [= value]

The AutoScrollMethod Property syntax has these parts:

Part	Description
object	An expression evaluating to an object of type McView.
value	A mcAutoScrollMethods enumeration, as described in settings.

Settings

The settings for value are:

Constant		Value	Description
	mcasmNone	0	no auto scrolling or auto zooming is done
	mcasmScrollWhenMouseDown	1	auto scrolling occurs only when the left mouse button is down.
	mcasmScrollWhenMouseLingers	2	auto scrolling occurs when the mouse lingers close to a border, whether the left mouse button is down or not.
	mcasmZoomWithMouseWheel	4	or this bit in to enable zooming with the mouse wheel when the Ctrl key is pressed.

Remarks

The McView window can be auto panned or scrolled when the mouse gets near a border (this can be limited to only occur when the left mouse button is down), and the Magnification can be automatically zoomed in or out when the mousewheel is rotated. The AutoScrollMethod enables or disables these features.

By default, auto pan/scroll is enabled only when the left mouse button is down, and mousewheel zoom is enabled (i.e. both mcasmScrollWhenMouseDown and mcasmZoomWithMouseWheel bits are set).
