2.5 Methods and Properties

After creating an object, the next step is to use it. This is primarily done through method calls and property accesses. To call a method of the object, do it as if the method was a function stored in a Lua table whose key is the method name:

-- Here we call the method 'Show' of the COM object
myobj:Show()
-- A method with a return value
result = myobj:CheckState()
-- A method with parameters
file = myobj:LoadFile("test.xyz", 1)
-- A method with output values
x, y = myobj:UpdatePosition(x, y)

To read or write simple properties, one must simply use them as if they were normal table fields.

-- Reading properties
value1 = obj1.Value
value1 = obj2.Value
-- writing a property
obj3.Value = value1 + value2

Automation includes support to parametrized properties. These can be accessed (or written) using accessor functions.

value = obj:getMatrixValue(1,1)
value = value*0,125
obj:setMatrixValue(1, 1, value)
