Setting Selection of JTree?

I have a TreeSelectionListener that calls a method for reading in data, when clicking on a treenode (The Method-call is in valueChanged() ).
I'd like to select the selected node in another part of my program to read in the data again. (Like a reload in an Internet Browser)
I tried the following but without success:
tree.setSelectionPath(tree.getSelectionPath()); //this code has no effect
tree.repaint();
Thanks for any help!

The setSelectionPath() method will only call the listener method if there is a change in the path. Since you are passing the same selected path as the new selection path, there is no change in the path, hence no call to the listener method.
Just as a workaround, you might just do the following and try out:
Treepath path = tree.getSelectionPath();
tree.setSelectionpath(null);
tree.setSelectionPath(path);
tree.revalidate();
tree.repaint();
Hope this helps!!

How to set selected file in FileChooser showSaveDialog to default file name

Hi,
How do I set selected file in JavaFX 2.0 FileChooser showSaveDialog, so I can prompt the user with a suggested default file name?
I am converting a Java Swing application I wrote a few years ago to JavaFX 2.0.
In the Swing application, I use setSelectedFile() as follows:
JFileChooser jFileChooser = new JFileChooser();
jFileChooser.setSelectedFile(new File(backupfile));
jFileChooser.setCurrentDirectory(new File(outputDirectory));
FileFilter filter = new FileNameExtensionFilter("Comma Delimited (*.csv)", "csv");
jFileChooser.addChoosableFileFilter(filter);
jFileChooser.setFileFilter(filter);
filter = new FileNameExtensionFilter("XML Document (*.xml)", "xml");
jFileChooser.addChoosableFileFilter(filter);
jFileChooser.setAcceptAllFileFilterUsed(false);
jFileChooser.setDialogTitle("Export File");
int returnVal = jFileChooser.showDialog(jFrame, "Export");
This would show a file chooser with the file name text field pre-populated with a default backup file name.
I can't find an equivalent in JavaFX.
Also, in the Swing application, I was able to determine which extension filter was selected at run time using getFileFilter().getDescription() as follows:
String extension = jFileChooser.getFileFilter().getDescription();
if (extension.equals("XML Document (*.xml)")) { ...
I can't find an equivalent in JavaFX.
Thanks,
Barry

You can use the open sequence file method on the application manager (then you only need to wire the file path)

How to set selected all checkboxes in all dataTable's rows?

Hi there,
I'm trying to perform this simple task: having a dataTable with a column containing checkboxes, how can I allow (with a button, a "super" checkbox or so) to simultaneously set selected all checkboxes in all rows?
And - is it possible to do so without calling the submit of the page?
Thanks to everyone!

Yes, the paging for <h:dataTable> works pretty good, it manages the task through four methods created in the java code -- DataTable1_firstPageAction(), DataTable1_previousPageAction(), DataTable1_nextPageAction(), DataTable1_lastPageAction() -- without adding any javascript in the jsp page.
Maybe I could test if a java script similar to the <ui:table>'s one fit also the dataTable...
thanks

Set selection range in Inbox of Interaction Center Winclient

Hi Gurus,
Does anybody know how to change the set selection range (dates) of the Planned Activities in the Inbox nail of the Interaction Center Win Client.
Thanks.

Hello,
I would like to add a side-question to this topic. My client is using CIC0 on CRM 4.0 to create sales orders, complaints and some customers. The functinality is limited (low number of orders & customers created like this, most are created in R/3 directly) but still it is there: customer-specifc IC WinClient profile, workspace, class etc...
My client wants to upgrade to CRM 5.2 and then CRM 2007 (SAP recommends ot do it in 2 steps), would that mean that the transactions wil not function anymore? Or would that mean that the transactions will function but will not be changeable anymore?
Thanks a lot.

How to set selected radioButton

Hi,
There are tons of examples on the websites to show you how to detect selected radioButton or click event. But It is not easy to find aone example to show you how to set selected radioButton.
Here is my code, but not working, Is it not well handle on it for Flex?
[Bindable]
private var selectedRadioButton:RadioButton;
private function initSelect(): void {
        selectedRadioButton = rb1;
<mx:RadioButtonGroup id="rbg" selection="{selectedRadioButton}"
                   change="rbg_change(event);" />
                <mx:HBox>

                      label="Lock" group="{rbg}" />
</mx:HBox>
Thanks

it's simple set its selected property true. For instance

How to set selected text on JTextPane ?

I need to set selected text on a JTextPane. I used setSelectionStart(); and setSelectionEnd(); but it doesn't work.
Can anybody help me?

I'm not sure if this is what you are looking for, but the following code sample was revised from the tutorial TextSamplerDemo.java. It will hightlight the word "selected" in yellow in the JTextPane.

        JScrollPane paneScrollPane = new JScrollPane(textPane);
        paneScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
        paneScrollPane.setPreferredSize(new Dimension(250, 155));
        paneScrollPane.setMinimumSize(new Dimension(10, 10));
        Container pane = getContentPane();
        pane.add(paneScrollPane);
    private JTextPane createTextPane() {
        JTextPane textPane = new JTextPane();
        String[] initString =
                { "This is the ", //regular
                  "selected",     //selected
                  " text. "       //regular
        String[] initStyles = {"regular", "selected", "regular"};
        initStylesForTextPane(textPane);
        Document doc = textPane.getDocument();
        try {
            for (int i=0; i < initString.length; i++) {
                doc.insertString(doc.getLength(), initString,
textPane.getStyle(initStyles[i]));
} catch (BadLocationException ble) {
System.err.println("Couldn't insert initial text.");
return textPane;

//Initialize some styles.
Style def = StyleContext.getDefaultStyleContext().getStyle(StyleContext.DEFAULT_STYLE);

JTree custom renderer setting selection background color problem

Hi,
I have a JTree with a custom icon renderer that displays an icon. The JTree is part of a TreeTable component. Iam having a problem setting the selection background uniformly for the entire row. There is no problem when there is no row selected in the JTable.
My present code looks like this:
Iam overriding paint in my renderer which extends DefaultCellRenderer.
     super.paint(g);
        Color bColor = null;
        if(!m_selected) {
             if(currRow % 2 == 0) {
                  bColor = Color.WHITE;
             } else {
                                                bColor = backColor;
        } else {
             bColor = table.getSelectionBackground();                  bColor = getRowSelectionColor();
     if(bColor != null) {
                       g.setColor(bColor);
         if(!m_selected) {
               g.setXORMode(new Color(0xFF, 0xFF, 0xFF));
         } else {
             g.setXORMode(new Color(0x00, 0x00, 0x00));
              I have a color I arrive at using some algorithm that I want using method getRowSelectionColor(). The other cells in the row have this color. But the cell containing the tree node shows different color. Iam not able to arrive at the right combination of the color to set and the xor color so my tree node also looks like the other cells in the row.
It is not a problem really as the table still looks good. Its just that the tree node looks like it has been highlighted and this might cause a problem when a table cell is highlighed later on in the application ( two cells in the row would be highlighted causing confusion).
Any help would be appreciated.

vidyut

Hi Camickr,
Thanks for the reply. Iam sorry I didn't include the sources the first time around. There were too many of them. I have created a small, self-contained, compilable program that demonstrates the problem and including it herewith. Still there's quite many files but they are all needed Iam afraid. The only one you will have to concern yourself fior this problem is the file IconRenderer.java. The treenode background and the other cells background are not in sync when table row is not selected in this example though. But they are in my real program. I just need them to be in sync i.e have the same background color when the row is selected.
Your help would be very much appreciated.
These are the files that are included below:
1. AbstractTreeTableModel.java
2. Bookmarks.java
3. BookmarksModel.java
4. DynamicTreeTableModel.java
5. IconRenderer.java
6. IndicatorRenderer.java
7. JTreeTable.java
8. TreeTableExample3.java (contains main)
9. TreeTableModel.java
10. TreeTableModelAdapter.java

How to set selected JTree from outside?

I have a JTree for example
-A
-a
-b
-c
-B
-a
-b
-c
-C
-a
-b
-cif the tree is All expand , it is easy to select the the tree by setSelectionRow(5), the result is "B.a", but how to select the the tree if all collap
-A
-B
-C
{code}
let say i want to select "B.c", it can't use setSelectionRow(7) becouse the row between 0-2. So how to select the tree if the tree is *collap*?

Multiple Selection in JTree, Drag & Drop

Hi everybody,
I was wondering if anyone knows how to implement Multiple Selection Drag and Drop in a JTree. I know that there used to be a bug in jdk 1.3 that would allow it, but I suspect 1.4 fixed that. I've implemented Single-selection just fine, but I'm trying do Multiple selection by drawing a selection rectangle and selecting whatever nodes are contained within that rectangle. So far I've implemented it by adding a MouseListener to my JTree, finding which rows are intersected by the rectangle and calling addSelectionRow() to add the TreePaths.
Is there an easier way to multiple selection now that the bug of 1.3(I hope) has been fixed?

Okay, now I've implemented the changes in the DragGestureListener, DragSourceListener and DragTargetListener in order to make Multiple Selection possible, however I want to select multiple items the same way Windows Explorer does by:
1. pressing the left-mouse button & dragging a "selection" rectangle which selects all the nodes contained within that rectangle.
2. then drag and drop is accomplished by pressing one of the selected nodes and dragging it (along with it's other selected siblings) to the destination.
In order to accomplish this I added into the Constructor of my JTree extending class this code:
public class MyTree extends JTree {
private static int x1, y1, x2, y2;
public MyTree(DefaultMutableTreeNode rootNode){
// Other Constructor stuff...
this.addMouseMotionListener( new MouseMotionListener() {
public void mouseDragged(MouseEvent e) {
x2 = e.getX();
y2 = e.getY();
repaint();
public void mouseMoved(MouseEvent e){ }
this.addMouseListener(new MouseAdapter(){
boolean dontRelease = false;
public void mousePressed( MouseEvent e){
x1 = e.getX();
y1 = e.getY();
int[] rows = getSelectionRows();
boolean dropSel = true;
if (rows != null){
for (int i = 0; i < rows.length; i++){
Rectangle rect3 = getRowBounds(i);
if (rect3.contains(x1, y1)){
dropSel = false;
dontRelease = true;
if (dropSel){
for (int i =0; i < rows.length; i++)
removeSelectionRow(i);
public void mouseReleased( MouseEvent e){
x2 = e.getX();
y2 = e.getY();
repaint();
if (dontRelease == false) {
Rectangle rect2 = new Rectangle(Math.min(x1, x2),
Math.min(y1, y2), Math.abs(x1-x2), Math.abs(y1-y2));
int rowCount = getRowCount();
for (int i = 1; i < rowCount; i++) {
Rectangle rect3 = getRowBounds(i);
if ((rect2.contains(rect3)) || (rect2.intersects(rect3))){
addSelectionRow(i);
dontRelease = false;
repaint();
The idea was that for every press of the mouse the 1st set of x,y coords. are taken to be the starting corner of the "selection" rectangle, and every point passed over while dragging would be the ending corner of the rectangle (so that in paintComponents, you could actually draw the rectangle).
Once the mouse is released it will check to see if the selection rectangle had contained or intersected any of the rows (basically I find how many rows are being shown in the tree and go through each one to see if there is intersection/containment). If a row is contained it becomes selected.
The remaining code in MousePressed is used if node(s) were previously selected it goes through and checks to see if this mouse press is at the location of one of the previous selected nodes - if it is then you can drag that node along with all of its siblings to their destination. However if your mouse press is not on one of the selected nodes - all the nodes should be deselected (like in explorer if you press away from your selection, you lose it). If you select and begin to drag your selection dontRelease should not allow the creation of another "selection" rectangle to occur during the drag-n-drop process.
-That's how I thought this code should work. Unfortunately as it does most of these things it does not correctly implement rule #2 of Windows Explorer (2. only by dragging one of the selected nodes can you drag them, otherwise you lose them)...currently as long as something is selected you can do a mouse press and drag from another location and as long as that location does not contain a node (like it is a blank area in the JTree), you can drag everything to the destination from when you start dragging.
I looked around and saw that perhaps it is due to the BasicTreeUI interferring with it's own MouseInputHandler() so I wrote MyTreeUI that extends BasicTreeUI, basically changing only the MouseInputHandler to contain the functions above, and I blocked /**/ those functions from my MyTree Constructor.
Then in my main class (the one of instantiate my MyTree and my DefaultMutableTreeNodes), I wrote:
try
String myTreeUI = "MyTreeUI";
UIManager.put( "MyTreeUI", myTreeUI );
UIManager.put( myTreeUI,
Class.forName( myTreeUI ) );
} catch( ClassNotFoundException cnfe ) {
System.err.println( "My Tree UI class not found" );
System.err.println( cnfe );
...thinking that that would be all I needed in order to set MyTreeUI as the JTree's UI, LooknFeel, etc. and although I did not get that ClassNotFoundException when running the program, it did not have any of the functionality that I had written ( I even wrote a System.out.println() in my MousePressed() function in MyTreeUI so that it would let me know that it is working and it never appeared). It was as if the MyTreeUI was not loaded or attached to the JTree. I also called:
System.out.println("this is UI: " + jTree1.getUIClassID() );
to see which UI my MyTree instantiate was using and it would printout TreeUI, not MyTreeUI. So I'm wondering what it is I'm doing wrong, I think I am very close to having this thing working but I want to know if anybody here would be able to let me know what I'm doing wrong or what would be the best way to go about implementing this Windows Explorer Multiple Selection JTree.
Sorry for the long-winded explanation,

ComboBox - Setting Selected Values from data

I am running into a problem in Flex 3 that seems to be
different from Flex 2. Maybe someone can help.
I have a function for setting a combobox selected item for a
location for a value when the titlewindow completes loading. The
value is a prior value from a prior save. In other words to set the
combobox a value from a prior session.
The locations xml file is loaded from a remote object
oncreationcomplete of the titlewindow. The setselectedvalue
function worked perfectly in Flex 2 but now only works in Flex 2
after the titlewindow is loaded. We tested this by running the
setselectedvalue function from a button click after loading.
The dataprovider length is showing 0 in our debugging. After
titlewindow up on screen the length is showing correct ( 35 ) - in
this case. Our viewxmlobject function is showing no xml. Shows xml
correctly after up on screen.
I have set the creationpolicy to "all". That did not help
either.
Any suggestions? Anyone. This is killing me. Spent two days
now trying to get back to working state.
private function SetSelectedValue_cbLocation(): void {
var xLocID:String = eLocationID.text;
//viewXmlObject( cbLocation.dataProvider )
for (var i : int = 0; i < cbLocation.dataProvider.length
; i++) {
//Alert.show( cbLocation.dataProvider
.locid, 'Location DataProvider', Alert.OK);
if ( xLocID == cbLocation.dataProvider.locid ){
cbLocation.selectedIndex = i;
break;
The combobox has the dataprovider set at design time.
<components:is2ComboBox id="cbLocation" x="585" y="4"
width="196" dataProvider="{xmlLocations.Record}"
labelField="locname" dataField="locid"
change="changeLocation(event)" disabledColor="#004080" prompt="1.
Please select location"></components:is2ComboBox>

Hard to say without seeing the code. Is the application
opening a pop-up window (the title window)? If so, where is the
combo box located? In the main app or the titleWindow? What calls
the SetSelectedValue_cbLocation() function?

Set select one of the cell in subtotal row in ALV report

Dear all,
I have a ALV report that has subtotal amount by Vendor ID.
I want to set the selection at vendor ID column (same row with subtotal).
I tried both set_selected_cell() and set_current_cell() methods, the cell selected is incorrect. It doesnt seem to be able to select any cell at the same row of SUBTOTAL.
lr_selections = ref_table->get_selections( ).
      lt_current_cell = lr_selections->get_current_cell( ).
      lt_current_cell-row = lt_current_cell-row.
      lt_current_cell-columnname = 'LIFNR'.
      lr_selections->set_current_cell( lt_current_cell ).
Please help. Thanks.

HP should provide tested recovery DVD every note book user. along with note book.
That is solution

How to set selected field in one choice

Hi,
I am using ADF 11.1.1.3 and dynamic tab shell.
In my application i create a question based on different subjects.
This subject is a drop down and the value of this drop down is coming from a VO.I dropped that VO as Select One Choice on my page fragment.
And create question.But when i go to edit that question i want to show the subject ( which was selected at the time of question creation) as selected and the other options in drop down.
For Example-
While creating i had 3 subjects
A,B,C .I selected B and created a question.
When i tried to edit the question i fetch the selected subject from one VO (VO to fetch the quetsions detal) and the list from another one.
The option i tried to resolve this is -
I drop the subject VO on edit page as select one choice and in in value of select ites i set the subject from questiondetailVO
*<af:selectOneChoice*
label="Subject:"
shortDesc="Select the program description"
*binding="#{backingBeanScope.backing_fragments_Ques.existingSubject}"*
*id="existingSubject"*
*showRequired="true"*
*unselectedLabel="Select Subject"*
*value="#{bindings.Subject_DESC.inputValue}"> (selected SUbject fom questionVO*
*<f:selectItems value="#{bindings.SubjectVO1.items}"*(Subject list from Subject VO)
*binding="#{backingBeanScope.backing_fragments_Ques.selectItems10}"*
*id="selectItems10"/>*
*</af:selectOneChoice>*
Any idea why this is not wokring or what is the correct way to achieve the same?

Hi,
I used following code
OAMessageLovInputBean lovbean=(OAMessageLovInputBean)webBean.findIndexedChildRecursive("AssetNumber");
OAMessageChoiceBean Choicevalue=(OAMessageChoiceBean)webBean.findIndexedChildRecursive("EamWrPriority");
if (pageContext.isLovEvent())
String lovInputSourceId = pageContext.getLovInputSourceId();
if(lovInputSourceId.equalsIgnoreCase("AssetNumber"))
if(lovbean!=null)
String slovVal=(String)lovbean.getValue(pageContext);
String prValue = getPRValue(pageContext.getApplicationModule(webBean).getOADBTransaction(),slovVal);
//String prValue = "1";
Choicevalue.setValue(pageContext,prValue);
}// end of processFormRequest
private String getPRValue(OADBTransaction con,String slovVal)
// System.out.println("In WorkRequestDffCO.getContextValue.organizationID" + organizationID);
String prValue = null;
String sql = "select decode(ml.meaning,'AC1',1,'AC2',1,'AC3',3,'AC4',3,null) from FND_LOOKUP_VALUES_VL ml ,mtl_serial_numbers msi where ml.lookup_type = 'MTL_EAM_ASSET_CRITICALITY' and msi.ASSET_CRITICALITY_code = ml.lookup_code and msi.serial_number = 'slovVal' ; //'30AC-TR002B'"
Statement st = null;
ResultSet rs = null;
try
st = con.createStatement(1);
rs = st.executeQuery(sql);
if(rs.next())
prValue = rs.getString(1);
catch(Exception e)
e.printStackTrace();
finally
try
if(st != null)
st.close();
if(rs != null)
rs.close();
catch(Exception e)
e.printStackTrace();
return prValue;
Query is executing but no value is retuning, if i use hard coded value in where condition like '30AC-TR002B' it is tt's returning value .

SelectBooleanCheckbox read-only after setting selection

Hello!
I'm trying to set the selection of an adf selectBooleanCheckbox!
When I set it by the pull-down menu (true, false) in the Property Inspector, everything is ok!
But when I set the selection depending on an ADF binding, the value is set correct,
but the checkbox is read-only and a change of the selection is impossible!
Here's the very simpel code of the Box:
<af:selectBooleanCheckbox
label="myLabel"
value="#{bindings.SomeValue.inputValue != null}"/>
Can anyone help me, how to enable the checkbox for selection?
Thank you very much!
Sebastian
PS: I'm using JDeveloper 10.1.3.3!

hi..
the previous error is ok now..
below is the script, the status is when click on 'Add new row' button, it will pass status = 'ADD_ROW' and set the startdate read only = False.
my question now is...
e.g i've a multiple rows (can display up to 10 rows) display in table form in the page....i query 3 rows of records, then i click 'Add new row' button,
how to make sure the 3 rows queried early is having startdate read only = Yes and for the new row startdate read only = False?
with the below codes it will set all rows startdate read only = False (including those queried data)... pls help...
public void setReadonly(String status)
OAViewObjectImpl vo = (OAViewObjectImpl)findViewObject("SeaoeAutoMosPVO1");
OARow row = (OARow)vo.first();
OAViewObject SeaoeAutoMosSummaryVO = (OAViewObject)findViewObject("SeaoeAutoMosSummaryVO1");
OARow SeaoeAutoMosSummaryRow = (OARow)SeaoeAutoMosSummaryVO.getCurrentRow();
if (status=="ADD_ROW")
row.setAttribute("StartDateRender", Boolean.FALSE);
