Hi!
I want to rearrange node position in JTree according to the id which has been saved in each node.
For example:
Node A has 3 children: B(id=9), C(id=2), D(id=5)
the displayed tree should be: A has 3 children: Node C at index 0, node D at index 1, Node B at index 2.
could anyone please help me?
thanks a lot,
Mia

Hi!
I'm using drag and drop method for my JTree. I got problem with the cursor image.
When i'm dragging one node to another node, the cursor image is changing . Although the position of droping the node is correct,the cursor still display image that actually indicates that the position is not correct(circle with line cross)

How can I change the cursor image so that the user will not confuse about it?
thanks

Hi Michael,
thanks for the explanations, it really helps

Hi!
I need help in using JFileChooser.
1.
I want to set the file type so that when the users want to open a file, they can only see <.dat> file.
This is my code:
JFileChooser fc = new JFileChooser();
fc.addChoosableFileFilter(new MyFilter());
fc.setAcceptAllFileFilterUsed(false);
class MyFilter extends javax.swing.filechooser.FileFilter
{
public boolean accept(File file)
{
return file.getAbsolutePath().endsWith (".dat");
}
public String getDescription() {
return "*.dat";
}
}
Problem: file type column has been set in the dialog box, but file chooser can't browse the folder(can't go inside directory and show the desired file).
2.
how to set the save dialog so that user only need to write file name but it is saved by adding the extension also.e.g fileName.dat
Thanks
