Check Box Node Tree
Frage
I have been trying to construct a checkbox node tree .
My specification is that i need the parent node to also be a checkbox and not a folder like icon .
I have realized that the default check box node tree will be a folder icon for a parent node and check box for a leaf node .
Any suggestions as to how i can achieve it ?
Lösung
Hi i think you need like followng image where node also contains the check box
you can achieve it as follow:
String[] strs = {"swing", // 0
"platf", // 1
"basic", // 2
"metal", // 3
"JTree"}; // 4
CheckNode[] nodes = new CheckNode[strs.length];
for (int i=0;i<strs.length;i++) {
nodes[i] = new CheckNode(strs[i]);
}
nodes[0].add(nodes[1]);
nodes[1].add(nodes[2]);
nodes[1].add(nodes[3]);
nodes[0].add(nodes[4]);
nodes[3].setSelected(true);
JTree tree = new JTree( nodes[0] );
tree.setCellRenderer(new CheckRenderer());
tree.getSelectionModel().setSelectionMode(
TreeSelectionModel.SINGLE_TREE_SELECTION
);
