treenode

So I have a TreeView in a C# windows form app. What I need is for some nodes to be "locked" so that they cannot be checked (or unchecked), based on a parameter. What I am doing now is this: private void tv_local_BeforeCheck(object sender, TreeViewCancelEventArgs e) { TNode node = (TNode)e.Node; //if a part node, cancel the action. if (node.Type == "Part") { e.Cancel = true; } //if a locked node, cancel the action if (node.Locked == true) { e.Cancel = true; } } This code works great on a single click of the checkbox, but if the user double clicks on a checkbox, it still checks/unchecks. I have

I have a TreeView and each of it's Node.Text has two words. The first and second words should have different colors. I'm already changing the color of the text with the DrawMode properties and the DrawNode event but I can't figure out how to split the Node.Text in two different colors. Someone pointed out I could use TextRenderer.MeasureText but I have no idead how/where to use it. Someone has an idea ? Code : formload() { treeView1.DrawMode = TreeViewDrawMode.OwnerDrawText; } private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e) { Color nodeColor = Color.Red; if ((e.State &

I want to set for each node in my JTree a different icon, actually I'm loading each node from a data base, with a "while", I set each icon like a root, leaf or parent. Like this: All my declarations are global: private ResultSet myResultSet; protected DefaultTreeModel treeModel; private DefaultMutableTreeNode rootNode,childNode,parent1,parent2; And this is the code where I set my nodes: myResultSet=rtnNodes(); /*Method that returns a RS with my nodes*/ while(myResultSet.next()){ switch(myResultSet.getInt(1)){ /*The first column is the type of node: root, parent, leaf...*/ case 0: treeModel =

I would like using my own Node class to implement tree structure in Java. But I'm confused how to do a deep copy to copy a tree. My Node class would be like this: public class Node{ private String value; private Node leftChild; private Node rightChild; .... I'm new to recursion, so is there any code I can study? Thank you! try class Node { private String value; private Node left; private Node right; public Node(String value, Node left, Node right) { this.value = value; ... } Node copy() { Node left = null; Node right = null; if (this.left != null) { left = this.left.copy(); } if (this.right !=

Gretings. I'm making an interface to edit scenarios for a game. Basically it consists of events, which have nested conditions and actions. So, i planned using two treeviews - one for selecting the event, and other for selecting the condition/action inside the event to edit. Now, you see, if i select an event (in left treeview) and then try to select something in the right treeview, the left treeview will stop showing the blue selection rectangle. This is obviously bad because now the user doesnt know which event is he editing! The only way i found to retain some sort of information about what
