I have list of many locators in my Manipulate:
{{listoflocs, listoflocsinit }, Locator, LocatorAutoCreate -> True }
And I have a slider there:
Slider2D[Dynamic[ slid ], {{0, -2}, {15, 15}}]
I want to freeze this slider (disable it) if any locator from listoflocs
is moved by user.
How can it be done?
