Returns the number of anchor points that a region is using to position itself.
number = MyRegion:GetNumPoints()
Returns
- number
- The number of anchor points used to position a region
- relativeTo
Example
-- a way of looping through all points
for i=1, MyRegion:GetNumPoints() do
print(MyRegion:GetPoint(i));
end
Details
- Returns zero on a newly-created region, or after a call to ClearAllPoints()
- Returns a positive integer after SetPoint() or SetAllPoints(); but the value will not increase further by repeated calls overwriting the same point (ie, setting "TOPLEFT" more than once)
- SetHeight(), SetWidth() and SetSize() do not actually create points and leave this value unchanged
