How to find that layer has group

[DeepAlone]

hi,

while writing my own plug-in, I need  to know that group name of  layers i.e.

which layer belong to which group. And whether the  selected element is layer or group

because layer and group can have same name.so that there must be a way to identify this.  

I used the following  code to know whether layer has group or not --

    SPErr         error           =  kSPNoError ;

     Boolean      isGroup      =  TRUE ;

     error = PIUGetInfo (classLayer, keyGroup, &isGroup, NULL) ;

code is executing normally sicne I got error = 0.But isGroup is always being 0 (FALSE) regardless of selection

of group or layer.

Can anybody suggest me how solve this issue.

Thank You,

DeepAlone.

You need to look at the entire layer stack and look to see if your layer is between a group start and group end marker. Run the getter plug-in on your document and you will see the layer group start and layer group end keys on the layer information. A layer does not have a key specifically saying that it is part of a group.
