How to set different Icons for Jtreenode

How to set different Icons for Jtreenode,i want to set icons for jtreenode,not only for leaf,open,closeicon,i hope that each node has a different icon.Thanks!

you need to check for the node value within a renderer, then assign an icon based on what you expect to get back.

How to set different icon for different type of document

Hi,
In my repository, we have different kinds of document (crystal report, word document, excel, jpg ...) and we wanna show specific icon for each kind. In my used ResourceRender I cann't see where to change (rnd:icon?)
Could someone tell me how to achieve that? Thanks
Ray

Hi Ray Li,
in KM icons are mapped to mime types. You can add a mapping or change an existing one as follows:
1. Go to Systemadministrarion - System Configuration - Knowledge Management - Content Management - Utilities - Icons
2. Add your mime mapping or change an existing one. To determine the correct mime type of your documents, just have a look at the details dialog in KM.
3. The path to the icons points (by default) to following directory on your KM server: usr\sap\SID\SYS\global\config\cm\etc\public\mimes\images
Here you can replace images or add some new.
Hope this helps,
Carsten
Seems like somebody thought the same thought bit faster than I did. Would like to delete my answer that does not contain any additional info. But dunno how to.

How to create a Platinum,Gold and Silver Customer and how to set different price for a single material based on customer?

Hi All,
How to create a Platinum,Gold and Silver Customer and how to set different price for a single material based on customer?

A good place to start is http://www.javaworld.com/javaworld/javatips/jw-javatip34.html
Also, do a search in this forum on HttpURLConnection. That class allows you to use POST method to send form data to a web server.
"Hidden" variables are only hidden in HTML. The HTTP that gets POSTed to the web server doesn't distinguish between hidden and not hidden. That is, the content you would write to the HttpURLConnection.getOutputStream() would be something like:
hidden=1&submit=ok(Of course, the variable names would depend on what the web server was expecting from the form.)
Also, be sure to set the Content-Type request parameter to "application/x-www-form-urlencoded"

How to set the icon for the entire application with JFrame.setIconImage

I set the icon on the main frame using JFrame.setIconImage(). The icon is shown properly in the main frame.
If more JFrames are opened from the main frame, the newly opened JFrames also show the icon.
However if JDialogs are opended, in some cases the icon set on the main frame is shown and in other cases the coffee cup.
What is JFrame.setIconImage() expected to do? Setting the icon for a single JFrame or the entire application?
How can I set the icon for the entire application?
How can I set the icon for JDialogs?
Thank you

In order for your dialogs to use the same icon as the frame, you must parent the dialogs to the frame which has the custom icon.

How to set different sounds for different events?

Hello I had Xiaomi Mi2s before and I could set different sound for every email account I had, for sms, for facebook and so on. How do I do it on my Xperia? Of course that for example SMS is more important then some facebook comment, so I would like to hear what happened because not every time I want to reach my phone.

How to Use different icons for JTree in the same level

Hi guys, i come cross a problem with JTree. The module need a JTree which need to represent items in the same level using different icons. For example:
[Icon for Root]Root
|
|_____________[Icon for Table] TABLES
|
|_____________[Icon for Index] INDEXS
|
|_____________[Icon for Views] VIEWS
As i know, the default behavior for JTree is using the same icon for all leaves and
the same icon for all node that has children. How can i achieve that?
Thansk a lot!

subclass DefaultTreeCellRenderer. if you overwrite the method below, then you can set the icon to whatever you want....!
    public Component getTreeCellRendererComponent(JTree tree, Object value,
                                boolean sel,
                                boolean expanded,
                                boolean leaf, int row,
                                boolean hasFocus) {
     String         stringValue = tree.convertValueToText(value, sel,
                           expanded, leaf, row, hasFocus);
        this.tree = tree;
     this.hasFocus = hasFocus;
     setText(stringValue);
     if(sel)
         setForeground(getTextSelectionColor());
     else
         setForeground(getTextNonSelectionColor());
     // There needs to be a way to specify disabled icons.
     if (!tree.isEnabled()) {
         setEnabled(false);
         if (leaf) {
          setDisabledIcon(getLeafIcon());
         } else if (expanded) {
          setDisabledIcon(getOpenIcon());
         } else {
          setDisabledIcon(getClosedIcon());
     else {
         setEnabled(true);
         if (leaf) {
          setIcon(getLeafIcon());
         } else if (expanded) {
          setIcon(getOpenIcon());
         } else {
          setIcon(getClosedIcon());
        setComponentOrientation(tree.getComponentOrientation());
     selected = sel;
     return this;
    }

Jtable: set different icons for selection/deselection

Hai,
I have designed a Jtable, I would like to set a column that has to show different icons when selected/deselected that row. To be specific when you click for the first time, it has to show ICON1 and if you click again it has to show ICON2. Any ideas ???
Thanks,
Bala.

I haven't tried this - so take it with a grain of salt. In your table model, you can define the getColumnClass for the column as ImageIcon.class. In the getValue for that column, you would return the icon.
In order to get the cell to act like a button .. so you can alternate between the icons ... is a little more complex. There is a book on Advanced Swing by Kim Topley that gets into making cells act like buttons. This part works because I have tried it -- but I wasn't displaying icons.
good luck!

How to set different font for numbers in headings and TOCs

Hi,
I've noticed some people use a different font for numbers in headings and TOCs to get some extra magic. Is there any way to automate such use of fonts in the paragraph styles?
Oh, and any suggestions on what fonts would be good for numbers?
Thanks!

I was merely continuing on the original theme -- any digit in any character style. It was only later revealed that (a) the OP needed old style figures, and (b) those were available in his font from the start.
The negative lookahead is the answer to his question (copied in full now)
Based on the above InDesignSecrets tutorial, does anyone know what to do if some of the numbers end with a dot or a comma?
Like the Norwegian date format: 13. mai 2009
Or the Norwegian way of pricing items: 2900,-
and my example shows it can be done, but with an added caveat. If digits are to be set in red, using the exceptions the OP asks for, my example sentence will come out as
"Think of a number between 1 to 10, but don't use 9."
rather than the (here) intended
"Think of a number between 1 to 10, but don't use 9."
