Tooltip for a JLabel of a renderer

Hello,
I'd like to set a tooltip for certain labels (defined both with an icon and text) of a tree cell renderer and a table cell renderer, too (extended of superclasses javax.swing.tree.DefaultTreeCellRenderer and javax.swing.table.DefaultTableCellRenderer, resp.) using a statement like
rendererLabel.setTooltipText(myToolTip);
Unfortunately no tooltip appeared after hovering the mouse cursor over the icon or text of the tree label.
I also tried to set
ToolTipManager.sharedInstance().registerComponent(tree);
before instantiating the renderer - also with no effect to the tooltip behaviour.
Currently I work with Java 1.5.0_16.
What may be the reason, that no tooltip appears?
How can a tooltip be realizied for labels in tree and tablre renderers?
Thomas Wiedmann

The renderer code has this structure:
public class MyRenderer extends DefaultTreeCellRenderer {
     public Component getTreeCellRendererComponent(JTree tree, Object value, boolean isSelected, boolean isExpanded, boolean isLeaf, int index, boolean hasFocus) {
          JTextPanel pane = new JTextPanel();
          pane.setLayout(new FlowLayout(FlowLayout.LEFT, 2, 0));
          if (data instanceof MyDataObject) {
               MyDataObject myObj = (MyDataObject)data;
               JLabel label = new JLabel();
               label.setIcon(myObj.getIcon());
               label.setText(myObj.getInfo());
               label.setToolTipText("MyTooltip");
               pane.add(label);
          return pane;

Tooltip for AttributedString?

Hi all,
I format text in a JTextPane with Styles and Attributes. This works fine and looks like I expected. Is it possible to add a Tooltip to an AttributedString?
I tried to add an AttributeComponent (in this case a JLabel) instead of the attributed string, because I could set a Tooltip for the JLabel. But the JLabel is not shown in my JTextPane. Maybe someone can give me a hint how to add a Tooltip to an AttributedString or how to display the JLabel as ComponentAttribute.
Thank you.

Here's some code for a MouseMotionListener I put on my JTextPane and use to implement a hyperlink cursor over styled text representing a url reference:
class TextPaneMouseMotion extends MouseMotionAdapter
public void mouseMoved(MouseEvent e)
    JTextComponent jt = (JTextComponent)e.getComponent();
    int pos = jt.viewToModel(e.getPoint());
    if (pos >= 0)
      Element el = d.getCharacterElement(pos);
      AttributeSet as = el.getAttributes();
      if (as.getAttribute(urlRef__) != null)
        jt.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
      else
        jt.setCursor(Cursor.getDefaultCursor());
}You can put anything you like into thje style - not just text attributes. Define your own keys (urlRef__ in my case) and if they are present when the mouse is over that part of the text then take the appropriate action.
So in your case may be put the tool tip text into the style against your own well-known key and if its there in the mouse listener set the tool tip on the JTextPane.

Multiline tooltip for JComboBox items.

Hi, As the title suggests I'd like to create a multiline tooltip for items in a combobox list.
I have implemented a multiline tooltip renderer which works perfectly on any component except JComboBox items.
I have also implemented a ListCellRenderer for a combobox that enables tooltips for the combobox items. Also works perfectly, except that they are single line tooltips.
The tooltip text is read from an xml file, therefore I have no control on how long the line of text is. Most of the time the text also contains newlines.
This is the method (overridden from JComponent) added to a subclass of a component so that that component uses the MultiLineToolTip:
    public JToolTip createToolTip() {
        MultiLineToolTip tip = new MultiLineToolTip(this);
        tip.setComponent(this);
        return tip;
    }And this is the ListCellRenderer used on the combobox, so that items have (single-line) tooltips enabled:
    private class ToolTipEnabledComboBoxRenderer extends JLabel implements ListCellRenderer{
         public ToolTipEnabledComboBoxRenderer(){
              setOpaque(true);
         public Component getListCellRendererComponent(JList list,Object value,
                                                          int index,boolean isSelected,
                                                          boolean cellHasFocus) {
              String entry = (String)value;
              if (isSelected || cellHasFocus) {
                   this.setBackground(list.getSelectionBackground());
                   setForeground(list.getSelectionForeground());
              } else {
                   this.setBackground(list.getBackground());
                   setForeground(list.getForeground());
              this.setText(entry);
              if(isSelected || cellHasFocus){
                   if(constraint!=null &&combobox!=null &&
                               constraint.getType() == Constrained.CONTROLLED_VOCABULARY){
                        String tooltip = ((ControlledVocabulary)constraint).getEntryDescription(entry);
                        if(tooltip==null || tooltip.equals("")){
                             tooltip="";
                        list.setToolTipText(tooltip);
              return this;
    }It seems to me that what I have to do is subclass the list used by the combobox and override the createToolTip() method. But how can I set the list used by the combobox? As far as I know the only time I can access the list is in the getListCellRendererComponent() method of the ListCellRenderer, in which the list is a parameter.
Any ideas?

Setting tooltip for columns in a JTable

Hi!
I have a JTable inside a JScrollPane. How do I set tooltip for each columnheader of the JTable?
I have noted that if I don�t have the JTable within the JScrollPane, the columnheaders are not shown.
Regards
Johan

1) You need to set the tooptip text on the renderer for the column (yourTable.getColumnModel().getColumn(...).getHeaderRenderer()).
2) The header is a separate component to the table. When you add a table to a scroll pane it automatically adds the header to the scroll pane too. You can get the component (yourTable.getTableHeader()) and add it to your own container if you wish.

Tooltip for datagrid's cells

I know how to create a tooltip for datagrid and/or its
columns. Is it possible to create a tooltip (or something similar)
for each cell? So whenever the mouse is over a certain cell, a tip
would be shown for that cell that depends on the value of the cell.
Similar functionality can often be seen in web-based database apps:
an Ajax query gets related data from a database on mouseOver.
My need and idea is to
- show a simple text list as a tooltip
- the text would be fetched from a database via a web service
- the fetch would be based on datagrid's (hidden) rowid and
each column's (hidden) column id (which are real database columns)
- the database structure is an n:m relation i.e. one
rowid+colid can refer to several items that are then used in the
tooltip
Use case: A number is displayed in the datagrid. The need is
to display 0-n references related to that specific figure (e.g.
book names, notes etc) in the tooltip. Next cell's tooltip would be
showing different references.
Anybody any ideas or suggestions? Thanks!

Hi,
Did you try creating a custom itemRenderer and handling the
mouse events for that item renderer component. There is also a
property called dataTipFunction, please check that too.
Hope this helps.

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

Setting icons in a JLabel table cell renderer

I am using a JLabel as a renderer for one of the columns in a JTable
Within the renderer class I use the following code to set the icon on the label. The icon is decided on the information for that particular cell which is held in the table model.
<CODE>
URL url = c.getResource("/images/icon.gif");
this.setIcon(new ImageIcon(Toolkit.getDefaultToolkit().getImage(url)));
<CODE>
When the icon gets set for one renderer it gets set for all other renderers as well. This does not happen when I set the text on one of the JLabel renderers.
How can I make it so that the icon only gets changes for one of the renderers.

You need to put this code into the getTableCellRendererComponent method. You should probably store all the possible icons at the class level otherwise you might end up loading an image each time a cell is rendered:
public class MyTableCellRenderer extends DefaultTableCellRenderer
protected Icon icon1;
protected Icon icon2;
protected Icon icon3;
public MyTableCellRenderer()
    icon1 = new ImageIcon(c.getResource("/images/icon1.gif"));
    icon2 = new ImageIcon(c.getResource("/images/icon2.gif"));
    icon3 = new ImageIcon(c.getResource("/images/icon3.gif"));
public Component getTableCellRendererComponent(...)
    if(...)
      setIcon(icon1);
    else if(...)
      setIcon(icon2);
    else if(...)
      setIcon(icon3);
    else
      setIcon(null);
    return super.getTableCellRendererComponent(...);
}Hope this helps.

How to make tooltip for DataGridColumn

Hi, I'm trying to get a tooltip for whenever the user mouses
over a column header in a DataGrid. I've seen some talk about
creating my own ItemRenderer to do this but looking at the Flex
docs, I see that the existing DataGridItemRenderer for a
DataGridColumn has a tooltip attribute but I have been unsuccessful
in getting it to work. Should I in fact make my own ItemRenderer or
is there any way to expose it in the existing DataGridItemRenderer?
Can anyone advise what the best way to do this is? Thanks!

We can do like this:
l_DataGridColumn.headerRenderer=new ClassFactory(YourHeaderItemRenderer);// use custom renderer instead of the default DataGridItemRenderer
And in you class YourHeaderItemRenderer extends DataGridItemRenderer, you can override some method:
override public function set toolTip(value:String):void {
     //set toolTip value here:
     toolTip= "column description";
this one is not dynamic, so if we want to, we can extend the DataGridColumn to add the toolTip field, and use it:
l_DataGridColumn.headerRenderer=new ClassFactory(YourHeaderItemRenderer);// use custom renderer instead of the default DataGridItemRenderer
l_DataGridColumn.toolTip="compute it here";
override public function set toolTip(value:String):void {
     //set toolTip value here:
     toolTip= (data as YourDataGridColumn).toolTip;
Of course in this case, the dataGrid columns must use the YourDataGridColumn instead of DataGridColumn.
All that to have a toolTip for the column, it's sad :-)

How to assign a tooltip for a field in ALV editable grid?

I have to display some instructions ( 50 chars long) for an editable field in alv.
How to do this?
BCALV_DEMO_TOOLTIP tells about assiging tooltip to an icon or symbol.
Thanks,
Ven..

Neither of these two example programs help much in regards to tooltips against any field of any row. Both of these examples use tooltips for Icons. I have also been looking for a single example of tooltips usage outside of these two programs, and have found nothing in SAP, or on the internet, so far.
Having said that, I have tried to implement the same method used by the later example, but have not got this to work. What I think we need is an example of this functionality where these Icons are not used!. I believe.

Jquery tooltip for sharepoint 2013 list (newform.aspx)

I am looking for a simple solution/jquery tooltip for SharePoint list form fields.
Something like below , but this one displays static text for each column and want tooltip text for each of my list column
<script type="text/javascript" language="javascript" src="/wz_tooltip.js"></script><o:p></o:p>
<a href="#" onmouseover="Tip('(This is test tooltip )');" onmouseout="UnTip();">
Thanks in advance!
<o:p></o:p>
Amrita Talreja

When you assign "Description" for every field in sharepoint list.SharePoint by default show this desc in a span just below the field control , like this.
<span class="ms-metadata">This is simple desc</span>
What you can try in jquery/javascript is to -
- Search for this span [class="ms-metadata"] in your form table (table[class="ms-formtable"])
- save its text() in a variable - var txtDesc = $("span selector").text();
- Hide this span -$("span selector").hide()
- Now you have dynamic desc message , you can add this as an "Title" attribute to your field control (textbox and other control)
- $("your field control selector").attr("Title", txtDesc );
Or can add a hyperlink for this -
<a href="#" onmouseover="Tip('"+ txtDesc +"');" onmouseout="UnTip();">
Thanks

Is there a way to have tooltips for every column in a TableView?

Hi there!
I found in documentation that any node and control can show a tooltip ( http://docs.oracle.com/javafx/2/api/javafx/scene/control/Tooltip.html ) but I can't get tooltips to work for TableColumn (a column from TableView).
Do you have any idea how could I have tooltips for each column of the table view?

TableColumn's are neither controls nor nodes, so you can neither set nor install tooltips on them.
You can use cellfactories to set tooltips on cells generated from the factories.
You can use css style lookups (node.lookup function) to get access to table nodes (such as the headers) after the tableview has been displayed on a stage and then manipulate the displayed nodes to add tooltips. It's not a great approach, but it is the only approach I know at the moment that would work.
