Changing JTree node text results in "..."
I'm working with a JTree, and I have a problem if I change the text displayed on a node. After changing the node, I call nodeChanged( node ) on the tree model.
What happens is that if the new text on the node is longer than the previous one, the text is cut short and the end replaced by "...". E.g. if the old text was "foo" and the new is "foobar", it turns out as "foo...". This happens even if there is more than enough space in the tree to hold the complete new name, e.g other nodes in the same column with longer names.
I guess somehow, the tree doesn't properly correct the layout of the cell to accomodate the longer text. I feel it is a bug, since I use the proper calls on the tree model to notify of the change.
nodeStructureChanged() will give the exact same behavior.
A solution is to use SwingUtilities.invokeLater().
SwingUtilities.invokeLater(new Runnable(){
public void run(){model.nodeChanged(node);}
});

JTree - node text doesn't fit when shown with icon
When I start off my JTree with a long string text for the node (without any icon...used setLeafIcon( null )... it displays fine. But during the execution of hte program an icon may appear next to a particular node - but when this happens, the icon displays fine and the text of the node is cut off (you just see a couple letters followed by the usual "...").
Any ideas?Thanks for the reply. I am not sure how to use that for what I'm doing...basically I am writing an AIM clone. And when a user sets an away message, I want an icon to appear next to their name, otherwise the icon is set to null.

Hi,
I set the background of a JTree to orange color by:
jTree1.setBackground(Color.orange);
However, the space around text is still in white color. Can anyone tell me how to change it too? Thanks.Hi, you could try -
((JComponent)
yourTree.getCellRenderer()).setOpaque(false);
I've not actually tested this, I'm just in the process
of figuring out the details of using trees.
colinThanks. It works with "yourTree.getCellRenderer()).setOpaque(true);" -

hi,
I have created a JTree node and i want to change the nodes string.
say for example from "child1" to "newchild1". Only the text displayed on the tree shoud be changed and the new value is got from a text box.
umaYou can change the value of a path using valueForPathChanged of the TreeModel:
tree.getModel().valueForPathChanged(path, str); -

Changes in the Text element of Bex Analyzer result Informaton tab
Hi Expert,
How can we make changes in the display of the Text element of the query result in the Information tab and save it? For eg. The User wants to display STATUS OF DATA TO rather than STATUS OF DATA in the Information tab of the query result.
The query is based on Multiprovider so it has Text Element of STATUS OF DATA
In the Workbook its easy to do, how do we do the changes in the query result in Analyzer and save it, so it always displays the chosen text element?
I dont want to create a workbook for the query, so is there any way to replace any of the Text Element with another existing standard Text element.Hi Ray,
Thanks for your reply.
The change is required in the Text element of information tab (once query is displayed there are buttons for Graph, Information), so the changes are required there for the text element and not for Characterstics and KF. -
Change of variable text in BEx selection screen
Hi all,
in our BW system the key users are allowed to create queries and also create variables. In some cases, especially for often used info objects like 0DATE the number of variables is increasing very quickly. The reason for this is, that 0DATE is used for a big variety of meanings e.g. delivery date, order date, invoice date etc.
So the users always create new variables only to have a meaningful description in the BEx selection screen, because they do not want only "date" to be displayed here. As result we have many different varianbles with exactly the same technical settings with only different names.
So my question is: Is it possible to change the diplayed text in the selection screen for each query without having to create a new variable?
Thanek you and best regardsHi Stephan,
Changing the diplayed text in the selection screen for each query is not possible.You have to create a new variable for each query.
Rgds,

E-mail changes to unreadable text when moved to another mailbox folder
Hi,
when moving a correct received e-mail to another mailbox folder, the mail and the attachment will change to unreadable text and it looks like the column below.
On my iPad and iPhone the mail and the attachment is shown correct. If I forward it to my own account again, the mail is also correct shown an my imac27, as long as it resides in the in-box.
On the other hand, there are lots of mails+attachments with "normal" behavier when moved.
Any idea about that?

Xml in JTree: how to not collpase JTree node, when renaming XML Node.
Hi.
I'm writing some kind of XML editor. I want to view my XML document in JTree and make user able to edit contents of XML. I made my own TreeModel for JTree, which straight accesses XML DOM, produced by Xerces. Using DOM Events, I made good-looking JTree updates without collapsing JTree on inserting or removing XML nodes.
But there is a problem. I need to produce to user some method of renaming nodes. As I know, there is no way to rename node in w3c DOM. So I create new one with new name and copy all children and attributes to it. But in this way I got a new object of XML Node instead of renamed one. And I need to initiate rebuilding (treeStructureChanged event) of JTree structure. Renamed node collapses. If I use treeNodesChanged event (no rebuilding, just changes string view of JTree node), then when I try to operate with renamed node again, exception will be throwed.
Is there some way to rename nodes in my program without collpasing JTree?
I'am new to Java. Maybe there is a method in Xerces DOM implementation to rename nodes without recreating?
Thanks in advance.I assume that "rename" means to change the element name? Anyway your question seems to be "When I add a node to a JTree, how do I make sure it is expanded?" This is completely concerned with Swing, so it might have been better to post it in the Swing forum, but if it were me I would do this:
1. Copy the XML document into a JTree.
2. Allow the user to edit the document. Don't attempt to keep an XML document or DOM synchronized with the contents of the JTree.
3. On request of the user, copy the JTree back to a new XML document.
This way you can "rename" things to the user's heart's content without having the problem you described. -

Can I change the standard text for web item 'INFO_FIELD_ITEM'?
Hello experts.
I made a WAD template using web item 'INFO_FIELD_ITEM'. In data binding, I used the 'Last refresh' of general text elements. As a result, in the web browser I can see the last update date & time. (e.g. 'Last refresh: 2007.01.17 17:34:44') Then our customer want to change the default text "Last refresh" as "Working time".
How can I change this?
I tried to change the text symbols for program SAPLRRSV. But it worked only in Bex Analyzer not in the web.
Our server version is Netweaver 2004s and SP10.
Best regards.
JY Park.Hello,
I had the same problem - just wanted to display the values of a variable in an info-field, but not the caption.
I found out, that there's a tag for Info-Field Item called ONLY_VALUES (it's the checkbox under the headers visible checkbox in the properties dialog of the Info-Field Item; in my WAD version, there's no label assigned to this checkbox, so it was not easy to find out what it should be),
You have to set it to 'X' (check it) ; then you get the unformatted value of the variable (no caption anymore).
<bi:INFO_FIELD_ITEM name="INFO_FIELD_ITEM_1" designheight="500" designwidth="350" > <bi:WIDTH value="350" />
<bi:HEIGHT value="500" />
<bi:DATA_PROVIDER_REF value="DP_1" />
<bi:HEADERS_VISIBLE value="" />
<bi:ONLY_VALUES value="X" />
You have to insert the info-field item between span tags so that you can define your own formatting values.
The ONLY_VALUES tag works the same as the tag 'RENDER_AS_TEXT' you have with the text item , see
http://help.sap.com/saphelp_nw70/helpdata/en/e3/e60138fede083de10000009b38f8cf/frameset.htm
There's only one disadvantage: If you have chosen a lot of variable values (multiple selection), the variable string gets very long and no line break is performed, because all blanks in the string are replaced by nbsp's. I solved this with a little Java Script, replacing the appropriate nbsp-s with br tags.
Hope it helps

Parse and display xml doc when click on JTree node?
Ok so here is the code that I have now. You will have to make alot of html files to run the program, but they can be empty for now. What you can do is just put the same exact html file to be displayed in each node element. for example.
DefaultMutableTreeNode n1_node1_b1 =
new DefaultMutableTreeNode(new ModuleInfo("Device", "device.html"));could be changed to
DefaultMutableTreeNode n1_node1_b1 =
new DefaultMutableTreeNode(new ModuleInfo("Device", "status.html"));And just keep adding the status.html page to each one of the nodes.
anyway.
For now when I click on the node, the html file is displayed in the JScrollPane rPane = new JScrollPane(htmlPane); and the htmlPane is a JEditorPane
what I need it to do.
When I click on the JTree node. I would like to go out to an xml file, parse the information in it, and display it to the pane.
I will need to later, be able to add, edit, or delete information on the xml through the pane later.

I can't seem to figure out how to change certain node icons in a JTree due to a 3 letter string. For example 2 nodes one saying "Intro" the other say "Edit - SEC" - the one with SEC has a different icon to "Intro"
MyRenderer class, here the code which is used to check the string of the node......
if(leaf && isSecuredFile(value)) {
setLeafIcon(leafSecuredIcon);
setToolTipText("This file is Secured Access Only");
else {
setToolTipText(null);
return this;
protected boolean isSecuredFile(Object value) {
DefaultMutableTreeNode node = (DefaultMutableTreeNode)value;
NodeRecord nodeInfo = (NodeRecord)(node.getUserObject());
String nodeTitle = nodeInfo.NodeRecord;
if(nodeTitle.indexOf("SEC") >= 0) {
return true;
return false;
}// MyRenderer class
I tried the above piece of code, and it compiles with no errors but when I try to run the applet it comes up not initialised with the following....
java.lang.NoClassDefFoundError: MyRenderer
at firstPanel.<init>(firstPanel.java:99)
at JNavigator.jInit(JNavigator.java:55)
at JNavigator.init(JNavigator.java:40)
at sun.applet.AppletPanel.run(AppletPanel.java:344)
at java.lang.Thread.run(Thread.java:484)
However if I take out this code it works fine but I need to be able to assign different icons depending on the node title string. Therefore I need help.here's the whole class, if thats any help...
public class MyRenderer extends DefaultTreeCellRenderer {
ImageIcon leafIcon;
ImageIcon leafSecuredIcon;
public MyRenderer() {
leafIcon = new ImageIcon("Leaf.gif");
leafSecuredIcon = new ImageIcon("LeafSecured.gif");
public Component getTreeCellRendererComponent(JTree tree, Object val, boolean sel, boolean expand, boolean leaf, int row, boolean hasFocus) {
super.getTreeCellRendererComponent(tree, val, sel, expand, leaf, row, hasFocus);
// sets Icons
setLeafIcon(leafIcon);
setClosedIcon(new ImageIcon("Folder95C.gif"));
setOpenIcon(new ImageIcon("Folder95O.gif"));
// set Expansion icons to + -
ComponentUI treeUI = tree.getUI();
if(treeUI instanceof BasicTreeUI) {
((BasicTreeUI)treeUI).setExpandedIcon(new ImageIcon("minus.gif"));
((BasicTreeUI)treeUI).setCollapsedIcon(new ImageIcon("plus.gif"));
// decides who icon to use
if(leaf && isSecuredFile(value)) {
setLeafIcon(leafSecuredIcon);
setToolTipText("This file is Secured Access Only");
else {
setToolTipText(null);
return this;
protected boolean isSecuredFile(Object value) {
DefaultMutableTreeNode node = (DefaultMutableTreeNode)value;
NodeRecord nodeInfo = (NodeRecord)(node.getUserObject());
String nodeTitle = nodeInfo.NodeRecord;
if(nodeTitle.indexOf("DOM") >= 0) {
return true;
return false;
}
