Accessing the List of Selected Objects

- The Selection object/class is a kind of a specialized collection. Each selected object is a member and can be accessed via enumerating or using the Item property:

// C++ API
Selection sel( Application().GetSelection() );
for( LONG i=0; i<sel.GetCount(); i++ ) 
{
   SIObject obj( sel[i] );
   Application().LogMessage( obj.GetName() );
}
SIObject objByIndex( sel.GetItem(0) ); // Access by index
SIObject objByName( sel.GetItem(L"grid") ); // Access by name

// C# (object model)
CXSIApplication app = new CXSIApplication();
foreach (CollectionItem itm in app.Selection)
{
   app.LogMessage(itm.Name, siSeverity.siInfo);
}
SIObject objByIndex = (SIObject)app.Selection[0];           // Access by index
SIObject objByName = (SIObject)app.Selection["cone"];       // Access by name

// JScript
var e = new Enumerator( Selection );
for( ; !e.atEnd(); !e.moveNext() ) 
{
   var obj = e.item();
   LogMessage( obj );
}
var objByIndex = Selection(0); // Access by index
var objByName = Selection("grid"); // Access by name

' VBScript
foreach obj in Selection
   LogMessage obj 
next
set objByIndex = Selection(0); ' Access by index
set objByName = Selection("grid"); ' Access by name

# Python
for obj in Application.Selection :
   Application.LogMessage( obj.Name )
objByIndex = Application.Selection(0) # Access by index
objByName = Application.Selection("grid") # Access by name

# Perl
for ( my $i=0; $i<$Application->Selection->Count; $i++ ) {
   $Application->LogMessage( $Application->Selection($i)->Name );
}
my $objByIndex = $Application->Selection(0); # Access by index
my $objByName = $Application->Selection("grid"); # Access by name
