Description
Finds and returns a child property of this group, as specified by either its index or name.
A name specification can use the same syntax that is available with expressions. The following are all allowed
and are equivalent:
m y l a ye r . p o s i t i o n
m y l a ye r ( " p o s i t i o n " )
m y l a y e r . p r o p e r t y ( " p o s i t i o n " )
m y l a ye r ( 1 )
m y l a ye r . p r o p e r t y ( 1 )
Some properties of a layer, such as position and zoom, can be accessed only by name.
When using the name to find a property that is multiple levels down, you must make more than one call to
this method. For example, the following call searches two levels down, and returns the first mask in the mask
group:
m y L a y e r . p r o p e r t y ( " A D B E M a s k s " ) . p r o p e r t y ( 1 )
Parameters
Returns
PropertyBase object or null if no child property with the specified string name is found.
