Setting background color to just the root node in a tree
How can I set a background color to just the root node in a tree? I got the node in the followig way in the renderer method.
IconNodeClass parentIconNode = (IconNodeClass)((IconNodeClass)value).getRoot();
Then how can I set the background for just the root node? Thanks.
You need to write ur own treeCellRenderer for that to be done

I would like to have a gray color to the root node before even I selected the root node.
Can I do that by setting the background color?
With the below code I am unable to set the background color to the root node even when I selected it. what else can i write to set the color to the root node?
if (((IconNodeClass)value).isRoot()) {
c.setBackground(Color.blue);
setIcon(null);
return c;I gave the following on your advice. But the background color is set to all the nodes. I want it to be set it to only the root node. How can I do that? Thanks.
if (((IconNodeClass)value).isRoot()) {
setOpaque(true);
c.setBackground(Color.gray);
updateUI();
setIcon(null);

Here i will get two outputs in same excel with different spread sheets,
now i want to set background color for headers i
ex:PARTY_ID,PARTY_NAME,AGENT_ID,TYPE_LOOKUP_CODE are the headers,in excel output i want background color as blue.
Please do need full help,its urgent req.Hello,
open the file in Excel and save it, just to ensure that Excel writes all the additional stuff it thinks is necessary.
Now change the background colour of the header and save the file again but with a different name.
Open both files in a text editor and look at the differences. That's what you need to change in your code.
Alternatively you can use packages like xml_spreadsheet or ExcelDocumentType, both write the same file format that you use in your code and you don't have to reinvent the wheel.

Could set background color of scrollbar?
Hy
is it possibile set background color of scrollbar?
thanksFrom my experience on this - yes, setting the colour (or the Visual Attribute) of the Block object will determine the background colour of the scrollbar. As far as I can see, it doesn't affect anything else.
I've had to ensure all my Blocks have a background colour set (to r88g88b88), because if it's left as <unspecified>, then the background of the scrollbar will be transparent. In Client-Server 6i, this isn't too bad, as the scrollbar still has a visible 'edge', but in 10.1.2.0.2 WebForms, this edge isn't present, meaning the background of the scrollbar isn't visible at all, just the two ends and a disembodied drag button. Not the end of the world, but some users thought it looked funny. -
GRC 10 LDAP query issue at the root node
Hello,
We are unable to do a search based on root node after successful LDAP integration but if we add a particular OU within the base entry then we are able to search the users for that specific OU. Specifying a specific OU is not the right solution as we have different OU for North America, Europe,
Latin America etc. regions. We need to specify the root node so that it will search for all the users in different region. We are getting the below operation failed error when we don't specify OU in the base entry.
Operation failed
Message no. LDAPRC001
Diagnosis
This is an error message that is triggered by the directory server.
It is not possible to analyze the error in the SAP system.
Procedure
Check the log files for the directory server (if they exist), to see if they
contain more information.
Please let us know if you guys have faced this situation and what was the resolution.
Thanks,
Gautam.We just have one LDAP server/connector set-up and it is working fine if we specifiy OU within the base entry along with the domain but it doesn't work if we remove OU and leave the base entry with the root node/domain. I have checked with our Basis team and we have only one forest..going to check with our AD team for the same. Since specifying OU in the base entry is pulling result from Active directory within LDAP t-code in GRC 10 system, I believe everything is fine from LDAP configuration standpoint and also SPRO configuration in GRC 10 system will come into scope when we try to retrive/populate those field in ARQ/CUP configuration in NWBC.
Below is the structure of our AD. If we leave the base entry with the root node/domain (DC=NR,DC=AD,DC=NEWELLCO,DC=COM) then it doesn't work and give the operation failed error message but if we add OU (OU=EMEA,DC=NR,DC=AD,DC=NEWELLCO,DC=COM) along with the root node then it does provide us with the result.
I'm going to follow up with the AD team but let me know if anyone got any ideas to resolve the above error.
Thanks,
Gautam. -

A couple of things...
Thats SQL - not PL/SQL
That is not a valid SQL statement, I'm surprised its not giving an error. Please post the exact region source.
When posting code on the forum, put {noformat}{noformat} (with the curly brackets and the word code in lowercase) above and below your code like this...
{noformat}{noformat}
SELECT *
FROM emp
{noformat}{noformat}
It will then appear like this... SELECT *
FROM emp
Cheers

How to set background color in JTF GRID
Is it possible to set background color in JTF GRID ?
Hello Pavo,
it's also possible to take the code from ebitar and use the expression within styleClass instead of inlineStyle.
E.g. you can define a custom style "StyleClassEmptyText" in your skin and set this styleclass if af:inputtext is empty.
By using style classes you can have the same style in the whole application and you are able to change this style on a single point(in the styleclass) for the whole application.

How do i get to display the nodes under the root node in a JTree?
In my JTree there is a root node.This root node has 4 child nodes.Each child node in turn has nodes under it.What i need to do is just display the child nodes under the root node i.e., the four child nodes and keep these child nodes in a collapsed state.How do i go sbout this?
Please try this:
tree.expandRow(0);
SwingUtilities.invokeLater(new Runnable(){
public void run(){
tree.setRootVisible(false);
});If you want to show the RootHandles:
tree.setShowsRootHandles(true);If you want to keep nodes in collapsed state (not expandable):
tel = new TreeWillExpandListener() {
public void treeWillExpand(TreeExpansionEvent event) throws ExpandVetoException {
throw new ExpandVetoException( event, "Don't want" );
public void treeWillCollapse(TreeExpansionEvent event) throws ExpandVetoException {
tree.addTreeWillExpandListener(tel);Some reading material:

Eyedropper Tool sets Background color instead of Foreground
Q: Why does the Eyedropper Tool set the Background color instead of the Foreground color when I click in my image?
A: The reason for this is that the Background swatch is "targeted" to accept the color information passed on by the Eyedropper Tool when you use it to sample a color. You can reset the behavior by clicking on the Foreground swatch in your Colors Palette/Panel. See the image below:
http://forums.adobe.com/servlet/JiveServlet/downloadImage/2-1902897-1946/Eyedropper-Focus- Infographic.png
No matter which swatch is targeted, you can choose to temporarily sample color into the other swatch by holding down the Option key (ALT on Windows) while you sample with the Eyedropper Tool.
If you'd like to have the current Foreground and Background colors (as displayed in your Toolbox) switch places, simply tap the 'X' key on your keyboard.
Finally, to reset the Foreground and Background swatches to their default of black and white, simply tap the 'D' key.Click on Windows and color. There is a setting there to change from
foreground to background. The one with the box around it is the default setting. -
