JTree- seperate tooltip for each node

hi,
i would like to have different tooltips for different nodes. in all tutorials they have given the method of assinging tooltip in a general class i.e. setting a tooltip for all leaf nodes etc.. But i would like to have seperate tooltip for each node.
thanx

hi,
Doing both of the above tasks will lead to have a tooltip same for all nodes. But i need all the toltips to be different for different leafs.
However i solved that problem using mouseListeners and getPath() method..
Now i have another problem. when i move my mouse over any leaf node(not necessarily selecting just on moving over the text) i would like to change the color of the text of that particular node to another color. If i use renderer to do this then it may change the color of all the nodes.
how it could be done for only a particular node and not for all. Aren't there any renderers for nodes.
thanx

  • ToolTip for each node of the Tree in JTreeTable?

    Hello! I have the problem that a ToolTip i have set in the TreeCellRenderer would not been displayed! Only one ToolTip will pop up over the JTreeTable with the ToolTipText that was set in the first CellRenderer. Does everybody have an idea?

    OK! Its done! The solution does not help exact, but it gives my the way! With the coordinates of the MouseEvent I can get the Value of the current table row and set the ToolTip text new. Teh ToolTipManager automatically repaints the ToolTip whit the new text and position.

  • Partial Selection in Jtree using checkbox for every node

    I have a application which uses a JTree. For each node in the tree, there is a checkbox attached to the node using a customized TreeCellRenderer. When some items of a node are selected i.e not all children of a node are selected using the chechboxes, how do i indicate using the checkbox of the parent node that only a partial list of nodes is selected. For this, i need to draw a little square in the checkbox indicating that it is partially selected. Any advice on this matter would be very helpful.

    It's a bit complicated. The default cell renderer doesn't actually put the tree nodes on your screen, it just paints the looks of them. That is, you see them on screen, but they are just painted, all mouse clicks etc. are sent directly to the JTree.
    In order to have a button in a tree node, and have that button respond to clicks, I believe you'd have to put the button in a TreeCellEditor. This means users will have to triple click the node to get the Editor in the renderer's place (db click only expands/implodes nodes).
    I have sucessfully used http://propertytree.dev.java.net/ to customize the behaviour of tree nodes, but I never have put a button in there... Have a look, you'll see what methods you need to overwrite.

  • I have multiple computers set up on homesharing under one itunes account. Can I use face time on all of them or do i need seperate accounts for each?

    I have multiple computers set up on homesharing under one itunes account. Can I use face time on all of them or do i need seperate accounts for each?

    I'd suggest you consider a cloud-based file sharing service such as Dropbox for this sort of use. iOS is not designed to be synched with more than one iTunes library at a time, so attempting to use it as you describe, connecting a single iPad to multiple computers, almost certainly won't work as you intend and is likely to cause nothing but headaches.

  • One Corporate Account for multiple departments or seperate accounts for each

    I would like to know if I can have one central account that can be shared among different departments. Or I would need to purchase seperate account for each department.
    Thank you for your help.

    You can have a master paid  account which create forms for each of your departments and have each deparment have their own account (could be a free account). The paid account can create the forms and share each form with the right deparment. This way each deparment have access to their own data only and can't mess up the other deparment forms and data.
    Really though.... I would recommand for each department to have their own paid account so that they are in full control of their forms.

  • XPath expression for each node name

    <DATABASE>
       <TITLE>
          <LANGUAGES>SGML<LANGUAGES>
       <TITLE>
    </DATABASE>Is there a direct way of retrieving xpath expression for each node name other than iterating through each node and identifying the parent node.
    Ex:
    DATABASE
    DATABASE/TITLE
    DATABASE/TITLE/LANGUAGES

    If you set an element ID using the DOM parser you can then look it up using the ID.
    private void setElementIDNode(String tag, String IDAttribute){
            NodeList nodes = doc.getElementsByTagNameNS(docNS, tag);
            for (int i = 0; i < nodes.getLength(); i++){
                Element node = (Element)nodes.item(i);
                node.setIdAttribute(IDAttribute, true);
    Element e  = doc.getElementById(elementID);But at some point you still have to iterate through the document. I believe XML Pull Parsers are a little different but I don't have experience with them.

  • I bought an iphone for my daughter and was unaware that we should have a seperate appleid for each.Now we share an id and get eachothers contacts and face time calls. I recently bought another iphone and want to change ids without loosing items and music.

    I bought an iphone for my daughter and was unaware that we should have a seperate appleid for each.Now we share an id and get eachothers contacts and face time calls. I recently bought another iphone and want to change ids without loosing items and music. How do I do this? The new phone is a 5.

    All purchases are always going to be associated to the ID that was used to purchase/download them.
    If you create an ID for your daughter you will want to check everywhere it is used to make sure you are not sharing messages and stuff. These would be iTunes/app store, iCloud, iMessages, and FaceTime.
    Go thru settings and find all mention of your ID.

  • Set up Virtual IP and Private IP for each node in RAC installation

    I am new to Oracle 10G RAC installation, based on the documentation, I need to assign a public IP, Virtual IP, private IP for each node, I know how to assign public IP for each node, I can assign the IP from the router, but I don't know how to assign the Virtual IP and private IP, since the private network is only connected by a switch, the switch is not able to assign IP to server, should I just go to the host file
    %SystemRoot%\system32\drivers\etc\hosts
    of each node to put IP in the file? what else should I do? I already read through the document from Oracle "Oracle Real Application Clusters, Quick Installation Guide for Oracle Database Standard Edition 10g Release 1 for window".

    I am still keep thinking why each node need a virtual IP address? if each mode has a virtual IP, which IP address the client can be specified? I have multiple application servers work as clients.

    Use a customized TreeCellRenderer:
        class Renderer extends DefaultTreeCellRenderer {
            public Component getTreeCellRendererComponent(JTree tree,
                                                          Object value,
                                                          boolean sel,

  • Tooltip for each record?

    Hi Folks,
    I have a list of names as a contact directory, showing
    contact details for each member of staff at my workplace.
    As some of the criteria are long descriptions, I'd like to
    show a few characters, and then when they hover over the link, it
    shows the whole word as a tooltip.
    Can anyone tell me how I can use query.currentrow to generate
    the triggers dynanically?
    I'm not sure where to start.
    Thanks in advance
