Getting a TreeNode with its Children

Hi Guys
DefaultMutableTreeNode node = (DefaultMutableTreeNode)tree.getLastSelectedPathComponent();I'm using the above statement to get the selected node ofa JTree, the problem being the node returned does not contain any children and it definitely has children below it in my JTree.
Any Ideas.
Thanks

Try:
DefaultMutableTreeNode parentNode = (DefaultMutableTreeNode)(node.getParent());
                                                 for (int i = 0; i<parentNode.getChildCount(); i++)
                                                      DefaultMutableTreeNode childNode =(DefaultMutableTreeNode)(parentNode.getChildAt(i));
                                                      Object fileChildNode = childNode.getUserObject());
                                                                                                       }Where node is the current selected child node

Yes.
On their iOS devices, under Settings>iTunes & App Store, they should use your Apple ID. When they log into iCloud, iMessage and Facetime, they should use their personal Apple IDs.

If you are referring to Activation Lock, the password for the Apple ID signed into the device is required, there is no way around this. If you do not have the information and cannot contact the previous owner, the device is useless.

The best thing you can do is turn the phone over to your local law enforcement as a lost/found device.

Drag a container and its children

Hi,
How do i drag a container and its children?
I see you can drag something and its parent, but i don't see how you can get the child from the draginitiator.
Thanks

I've had a chance to play with this now and I had a pop at using the JLayeredPane, throwing a component to the top which is a MouseListener and KeyListener and consume()s all the events. Works fine for the most part, until there's a JButton within the component - they manage to carry on handling events despite the consuming component over the top of them. Hover over them and they repaint, they're clickable, and so on. Hmm.

Working in Logic 9, how do I use a drum loop WITH ITS PRESET EFFECTS? I can drag and drop the loop but it plays dry in timeline. thanks

Working in Logic 9, how do I use a drum loop WITH ITS PRESET EFFECTS? I can drag and drop the loop but it plays dry in timeline. thanks

Here's the short-cut solution:
Green Apple tracks are MIDI files (so to speak). If you drag one from the loop browser (Capitol C Orchestral hit, as you mentioned in this exable) directly into the arrange page it creates the MIDI file and the instrument to play it back on.
HOWEVER.If you create and audio track first, THEN drag the green Apple loop onto that track, the loop will get "bounced" with the reverb in tact and you'll have the exact sound that you heard in the preview.
Make sense?
