Attaching property to a property

RK56

Hi,

The subject could be misleading as I dont know the correct terminologies. I have attached some values to CI window to use as global variables.

hiGetCIWindw()~>layer_M1 = (list("M1" "drawing") list("M1" "pin"))

hiGetCIWindw()~>layer_M2 = (list("M2" "drawing") list("M2" "pin"))

 

Now I want to group them into another level of depth like

hiGetCIWindw()~>layerUtils~>layer_M1 = (list("M1" "drawing") list("M1" "pin"))

hiGetCIWindw()~>layerUtils~>layer_M2 = (list("M2" "drawing") list("M2" "pin"))

How to do this? Also what is the correct way to ask this question?

Thanks

Ram

  • Hi Ram,

    Given that properties on window objects are just a reference to a SKILL structure, the simplest approach is to make layerUtils a hash table. Hash tables can be indexed using -> or ~> where the key is a symbol. The alternative is to make it a disembodied property list or a structure (defstruct); the disembodied property list would require you to use -> rather than ~> and the defstruct requires you to pre-declare the structure. Overall I think using a hash table is the simplest. For example (fixing the typos in your code too):

    hiGetCIWindow()~>layerUtils=makeTable('layerUtils nil)
    hiGetCIWindow()~>layerUtils~>layer_M1 = list(list("M1" "drawing") list("M1" "pin"))
    hiGetCIWindow()~>layerUtils~>layer_M2 = list(list("M2" "drawing") list("M2" "pin"))

    You then retrieve the value using hiGetCIWindow()~>layerUtils~>layer_M1 .

    Regards,
