Usage

From source file:SwitchTest.java

protected BranchGroup createSceneBranchGroup() {
    BranchGroup objRoot = super.createSceneBranchGroup();

    double labelScale = 20;

    // flip this boolean to either display all
    // the child nodes or to just display the 3, 6 and 7th.
    final boolean bDisplayAll = false;

    // create the Switch Node
    int nMode = Switch.CHILD_ALL;

    if (bDisplayAll == false)
        nMode = Switch.CHILD_MASK;// w  w w . j a  va 2  s .  com

    Switch switchGroup = new Switch(nMode);
    switchGroup.setCapability(Switch.ALLOW_SWITCH_WRITE);

    switchGroup.addChild(createLabel("Child Node 1", labelScale));
    switchGroup.addChild(createLabel("Child Node 2", labelScale));
    switchGroup.addChild(createLabel("Child Node 3", labelScale));
    switchGroup.addChild(createLabel("Child Node 4", labelScale));
    switchGroup.addChild(createLabel("Child Node 5", labelScale));
    switchGroup.addChild(createLabel("Child Node 6", labelScale));
    switchGroup.addChild(createLabel("Child Node 7", labelScale));

    if (bDisplayAll == false) {
        java.util.BitSet visibleNodes = new java.util.BitSet(switchGroup.numChildren());

        // make the third, sixth and seventh nodes visible
        visibleNodes.set(2);
        visibleNodes.set(5);
        visibleNodes.set(6);

        switchGroup.setChildMask(visibleNodes);
    }

    // finally add the Switch Node
    objRoot.addChild(switchGroup);

    return objRoot;
}
