LocatorAutoCreate

LocatorAutoCreate
is an option for LocatorPane, Manipulate and related functions which specifies whether new locators should be created when clicking away from existing locators.

MORE INFORMATION

The following settings can be given:

	True	create a new locator with any Alt+Click
	{min,max}	allow between min and max locators
	min	allow anything more than min locators
	All	create a new locator with any mouse click
	{All,{min,max}}	limit the number of possible locators

With LocatorAutoCreate->True, any Alt+Click that does not hit an existing locator will cause a new locator to be created at the position of the click. Alt+Click on an existing locator deletes the locator.

With LocatorAutoCreate->{min, max}, any Alt+Click that would decrease the number of locators below min or above max will have no effect.

LocatorAutoCreate->All specifies that any mouse click that does not hit an existing locator should create a new locator. Alt+Click deletes a locator.

When a new locator is added, its coordinates are placed at the end of the list of coordinates for the enclosing LocatorPane or other object.
