JTextField in JTree - make it editable

断了今生、忘了曾经 提交于 2019-12-04 16:40:06
does anybody have a sample code for a tree with check boxes and text fields? Because now I have a code for check box (only) based tree. I tried to implement also text fields in the tree (with Jlabels ). But I get stucked and I am really confused. I can't get any further and I hoped that you can help me. The issue is. I cant modify the text of JTextFields. The modification doesnt get saved. And I do not know how to add a JLabel in the same line of the JTextField Root | |- Node 1 | - [-] Activate simulation | - [100] Iterations |- Node 2 | - [x] Activate simulation | - [2000] Iterations package

A Table like JTreeTable with editable components like ComboBox, TextArea, CheckBox as Rows

Is there any custom plugin(like JTreeTable with editable java components) in java, like in the above image. I know this can be done by Extending JTreeTable or JXTreeTable Class or using TreeCellEditor etcetera... But, I need a quite exact structure like shown in the above image, Please guide me and Thanks in advance. trashgod Outline , seen here and here , uses the same renderer and editor schema as JTable . For example, to get a column of checkboxes, your RowModel implementation of getColumnClass() should return Boolean.class and your implementation of isCellEditable() should return true for

I have a table with fields category_id, category_name and parent_category_id. And parent_category_id has values from category_id which represents the parent child relationship. I dont have any fixed level of hierarchy, it may go up to 5 levels or 10 levels and there is no limit to that.. I need a code for how to implement this JTree to make thing work for me. I should be able to implement the same for Menu bar as well.. Please help me with this.. After googling I found this, Map<String, Node> idToNode = new HashMap<String, Node>(); //create nodes from ResultSet while ( resultSet.next() ){ Node

Not sure if this is the right spot to ask but I'm having a Java issue. I have some Java code that works in Java 6 but not in Java 7, the error is: java.lang.IllegalStateException: This function should be called while holding treeLock Using Java6 works but a few of our external users are running Java 7. I figured out the error was caused by a call to validateTree() , which works in java6 but in Java7 we need to call validate() . When I test it locally it works. Here's my problem, I started working at a big corporate and they won't let us make any changes to the code until its been very

Change JTree row height resizing behavior when rendering

拜拜、爱过 提交于 2019-12-04 06:55:13
I want to use a custom TreeCellRenderer containing three text fields only when a node is SELECTED, while use the default renderer when the node is NOT SELECTED. The problem is that although I've set an appropriate preferred and minimum size for the panel, JTree does not update the edited row height. On the contrary when I use the same panel as an editor, it is rendered correctly. Can someone explain why this is happening? Is there a recommended way to achieve a rendering resizing behavior similar to that of editing? Is there a method provided by JTree to set it directly or is it necessary to

changing how Nimbus LaF handles JTree node highlighting

I have been working to transition a Java application from WindowsLookAndFeel to Nimbus, largely successfully, despite Nimbus foibles. My users overall like the Nimbus LaF but didn't like some details, some of which I changed by consulting previous questions on this site. Example: I copied the LeafIcon, ClosedIcon and OpenIcon from Windows LaF (which they liked) and use them in the Nimbus version, for a nice combination of LaFs. Stuck on one last (?) problem. I have a JTree with a subclassed DefaultCellRenderer to create the appropriate node displays. This works fine under WindowsLookAndFeel.

Compound JTree Node allowing events to pass through to objects underneath

谁说胖子不能爱 提交于 2019-12-03 20:22:05
问题 I'm trying to create a JTree in which some nodes are compound objects containing a JLabel and a JButton. The Node is representing a server and port shown by the JLabel, the JButton will use the Desktop API to open the default browser and go to the URL. I have read the following already and have followed them as closely as I can. The Node is displayed how I want it (mostly - I can deal with making it nicer later) but when I try to click on the button the JTree is responding to the events, not

JTree: how to get the text of all items?

大城市里の小女人 提交于 2019-12-03 16:37:35
I want to get text of an JTree in format: root sudir1 node1 node2 subdir2 node3 node4 Is it possible? I wrote some code public static String getLastSelectedText(JTree tree) { DefaultMutableTreeNode node = (DefaultMutableTreeNode) tree.getLastSelectedPathComponent(); if (node == null) return null; return node.getUserObject().toString(); } But it get only selected component text. I think about expand tree and handle all nodes, but maybe it bad idea. I think you shouldn't build the string within a single function - but I do not know what exactly you aim at with your question. In order to keep my

updating JTree in java GUI

巧了我就是萌 提交于 2019-12-03 12:16:52
I used a JTree in my GUI and added it to a JFrame. When I want to update it and change it's nodes in another part of my program (while program is running, as an action performed) I try to add new nodes, or remove nodes to it; But my interface doesn't change. Please suggest me a solution. regards In addition to the insertNodeInto suggestion you can also use: DefaultTreeModel model = (DefaultTreeModel)tree.getModel(); DefaultMutableTreeNode root = (DefaultMutableTreeNode)model.getRoot(); root.add(new DefaultMutableTreeNode("another_child")); model.reload(root); You need to ensure that after

Adding and removing nodes from a JTree

徘徊边缘 提交于 2019-12-03 09:51:23
I have a very basic JTree . As I am on a rush, I'd prefer not to use TreeModel if it is not needed. I wrote a SSCCE to expose the problem: Sometimes I add a node. Other times I remove them. When I push Add , a node is correctly added. When I push Remove , it is supposed to remove the node, but it doesn't. Also, if I try adding more than one node, the tree stays with just the first node I added. I wrote an update method for the JTree , where I first erase all the nodes hanging from the root node, and then I look at which nodes and sub-nodes I have to create. What I am doing wrong here, apart
