Hello,
In my program, I have created tree for the directory structure available on a particular location say C:\MyDirectories.
Its woking fine, but tree shows the node as EXPANDABLE i.e. [ + ] even there are no subdirectories/files inside that node.
i.e. If the node is empty, then tree should not show the '+' ( EXPANDABLE sign) behind that empty node.
Regards
Does getChildCount work correctly for your nodes?
I am not using getChildCount.
this is the sample code I have written.
DefaultMutableTreeNode makeNewTree(File f, DefaultMutableTreeNode root)
{
DefaultMutableTreeNode root1 = new DefaultMutableTreeNode(f.getName());
File f1[] = f.listFiles();
for(int i = 0 ; i < f1.length ; i++ )
{
if(f1[i].isDirectory())
{
root1 = new DefaultMutableTreeNode(f1[i].getName());
makeNewTree(f1[i], root1);
root.add(root1);
}
}
return root;
}
Above is the recursive method which first creates the tree and then returns the node which is displayed.
If anything unclear, please ask.
Thanks and regards.
How can I remove the handle i.e [+ sign] behind the folder [node of the tree], if that folder doesn't have any sub folders. When I expand that node [which is empty] , Its [+ sign] gets removed.
Thanks and regards
