jtree

I have a JTree with a custom TreeModel and a custom TreeRenderer. The Tree Model contains a bunch of objects of different types. One of these types is displayed differently than the others: The displayed text is a concatenation of two fields of the object. When i edit the cell, I want to update one of these fields with the edited text. So far i got it working pretty well. My Problem: It is confusing when the text, which is displayed while editing, is the complete concatenated value of 2 fields, even though you're in fact just editing one of the fields. So i want to display only the content of

Basically I edit an attribute private string status="OK" in the UserObject() of a DefaultTreeNode() . I have a CustomRenderer which implements DefaultCellRenderer , which sets the Icon by rendering the "OK" attribute of UserObject of a TreeNode . Originally, when I select a node, the icon changes. I am using Tree.revalidate() & Tree.repaint() , and the change is being reflected. However, I am not sure if this very efficient. What would be the proper way of doing this? I tried doing TreeModel.nodesChanged(new DefaultMutableTreeNode(myUserObject)) but the TreeNodeChanged event will not fire. So

I want to make text editor with file browser so when I start my application I want to my program add nodes on JTree so it shows me all files and folders for example in My Documents folder, and to give me ability to access to those files and folders (especially to folders). I tried to figure out how Andrew Thompson did that from this example but I failed. I managed to create nodes for all files and folders from My Documents using this example . But thats all, I can't figure out how to generate nodes for other files and folders when clicking on one of nodes which represent folder. This is what I

Often, when using JTable or JTree user writes and assign it is own specific cell renderer. It is very common to inherit user's component from DefaultTableCellRenderer , and implements the renderer method getTableCellRendererComponent . It turns out that DefaultTableCellRenderer in fact inherits from JLabel, thus returns himself (this) when called to super (at the render method) and thus user's renderer can similarly returns himself (this) as well. And it all works well. My question is how can it be? Each time this method is called by the table, it is given different parameters, and the output

I know how to set custom leaf icons in JTree I know how to set custom closed/open icons for all group nodes But I can not set custom open/closed icons based on the group node names, for example of node could be called Emails (so it is nice to have an envelop icon) or one group may be called tasks and so on. I tried to do this by overriding the getTreeCellRendererComponent method of class DefaultTreeCellRenderer But changing the icon for the current node will affect for the next node only! How to set custom open/closed icons for individual groups? Please take a look at my code: Employee.java

I was looking for a a JTree implementation, that contains checkboxes and which: When you select one node, all its successors in the tree are automatically selected When you unselect one node, all its successors in the tree are automatically unselected When a parent node is already selected, and the selection was removed from one of its successors, the node color will be changed, to make it intuitive that although this parent node is selected, not all of its successors are selected (Like when you select components to install in common installers) A click on a node leads to (No need to hold

I want to build JTree which has nodes that contain check box + icon + data and tree selection algorithm. This is full example that demonstrate how to add checkbox to Jtree node. I used JTree with nodes based on File system content. I usesd also AddCheckBoxToTree.CheckTreeManager class to manage selection or semi selection options. Use public AddCheckBoxToTree.CheckTreeManager getCheckTreeManager() { return checkTreeManager; } method to play with selection tree path. for example: // clear all selected path in order TreePath[] paths=getCheckTreeManager().getSelectionModel().getSelectionPaths();

Problem Applying filtering on a JTree to avoid certain nodes/leaves to show up in the rendered version of the JTree . Ideally I am looking for a solution which allows to have a dynamic filter, but I would already be glad if I can get a static filter to work. To make it a bit easier, let us suppose the JTree only supports rendering, and not editing. Moving, adding, removing of nodes should be possible. An example is a search field above a JTree , and on typing the JTree would only show the subtree with matches. A few restrictions: it is to be used in a project which has access to JDK and SwingX
