Re: [JAVA3D] Switch Node behavior with removals...

[Luis Villablanca]

Hi,   I also noted this.  In order to avoid the shifting, instead of removing the child node I insert a phony empty BranchGroup node and maintain a parallel list of the available (deleted) switches.   regards --- Luis   ----- Original Message ----- From: JP Lee To: [EMAIL PROTECTED] Sent: Thursday, March 07, 2002 10:35 AM Subject: [JAVA3D] Switch Node behavior with removals... Hi:   I've just discovered that when a child node is removed from a Switch node, the successor elements are shifted one place, to remove any nulls that may exist within the element range (Switch uses a Vector to hold it's children). This causes problems with selection - child indices are now changed but not published to clients! Is there a way to deal with this other than forcing me to maintain a parallel structure to keep track of the actual index of Switch children in light of this feature of deletions?   thanks, jp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ John Peter Lee, Sc.D.                   (781) 839-4575 (office) Discovery Information Systems      (781) 839-4580 (fax) AstraZeneca R&D Boston              [EMAIL PROTECTED] Waltham, MA 02451                     www.astrazeneca-boston.com/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
