JTree changing Icons of leaves of a node

I have a Jtree with root node as "Project"
I have nodes as "color", "sports", "food" which in turn have leaves.
I have to set an Icon "Icon1" for all the leaves of node "color"
I have to set another Icon "Icon2" for all leaves of node "sports"
and have to set another Icon3" for all the leaves of node "food"
How do I go about doing it? Thanks.

Take a look at the Swing Tutorial, specifically http://web2.java.sun.com/docs/books/tutorial/uiswing/components/tree.html#display. This gives a straightforward example of changing icons (or anything on the node) by using a cell renderer.

Change icon of a non selected node in JTree

Hello
I have a swing application contening a JTree.
I'd like to know how to change the icon of a non selected node in my tree. I have the information about the node and its path. I try to change userObject information and the icon of the node with the setIcon of (DefaultMutableTreeNode), and reload the node (DefaultTreeModel) but it doesn't work.
Do I have to set the change in my CellRenderer ?
Any advice will be welcome
Anne

If you carefully look at the java tutorial tree, the change is made for all the leaf icon. What I want is to change the icon of a not selected node of my tree while I do other stuff with the other nodes like select, display their contents, drag them ...
the operation of a not selected node is independant from the selection in the tree.
So I still ask how to force a node to reload and take care of the change of his icon.

I have created CustomCellRenderer and i'm calling this class as follows
tree.setCellRenderer((TreeCellRenderer) new CustomCellRenderer(true));
The boolean value for the constructor (in this case it's true) will be set to
a local variable in the CustomCellRenderer class. Then upon clicking a node in the tree the boolean value (true) is set and the icon for that node should be changed as specified in the CustomCellRenderer class.
When i click on a node all the icons of that tree are disappearing.
Can any one help me in this issue

Cannot change icon UI property on node in hGrid's tree

Hi,
I created region of style hGrid (ID HGridRN).
Under HGridRN I created region of style tree (ID TreeRN).
Under TreeRN I have members and I want to set some dynamic property for nodeDef2 member.
HGridRN
__TreeRN
____members
______nodeDef1
______childNode1
________nodeDef2 <- I want dynamic icon on this node
________childNode2
I try to use next sequence of statements:
OAHGridBean hGridBean = (OAHGridBean)webBean.findIndexedChildRecursive("HGridRN");
OAWebBean treeBean = hGridBean.findChildRecursive("TreeRN");
*if (treeBean != null) {*
*..OATreeDefinitionBean nodeDef2 = (OATreeDefinitionBean)treeBean.findChildRecursive("nodeDef2");*
*..nodeDef2.setAttributeValue(ICON_ATTR, new OADataBoundValueViewObject(nodeDef2, "NodeIconAttr", "ComplectVO1"));*
Setting ICON_ATTR attribute doesn't change the icon in hgrid.
If fact I can even write nodeDef2.setRendered(false); but the node still exists in UI.
How to get reference to nodeDef2?

Hi,
It looks like, that yout context node V_HOME.1 has no elements ( = no data ), try to fill your context node by some data ( by supply method for example). Or you can try change cardinality of your V_HOME.1 node to 1..n.

JTree leaf icon

Hi,
I am doing a sort of explorer, with a JTree.
I know how to change icons for leafs, but sometimes my leafs are indeed branches but without nothing in it (an empty directory).
so the tree displays it as a leaf. But I would like that the tree displays it with the directory icon (but without the "+" sign).
How can i do this ?
Sylvain.

I haven't such problems...
Ok. You have to create your custom TreeCellRenderer and set it to the tree.
IconRenderer myRenderer=new IconRenderer ();
tree.setCellRenderer(myRenderer);
class IconRenderer extends JLabel implements TreeCellRenderer
public Component getTreeCellRendererComponent(JTree tree,
Object value, boolean sel, boolean expanded, boolean leaf,
int row, boolean hasFocus)
setText(value.toString());
//process value (value represents you tree node content)
if (!leaf) {
if (expanded)
setIcon(new ImageIcon("images/expanded.gif"));
else
setIcon(new ImageIcon("images/collapsed.gif"));
else {
setIcon(new ImageIcon("images/text.gif"));
MyObject myObj=(MyObject)value;
if (myObj.isBranch()) {
setIcon(new ImageIcon("images/branch.gif"));

Folder icon display at richfaces tree node

Hello All,
I would like to use richfaces tree structure.
But the issue with that is the folder icon display at each tree node.
For some reason i don't want the folder icon at the tree node.
Is there anyway to get rid of that?
I tried to change the image (iconFolder.gif) to some 1X1 pixel image in the richfaces jar file.
But when i added the new jar with new image for icon, that image is not loading.
I'm using Jboss4.2 as my application server.
Please help me to remove the folder display at tree node.
Thanks in advance.
Regards,
Elizabath

Hi,
I could see the icon attribute to specify the folder icon at the node. I placed a 1x1 pixel image as the iconfolder image. But that results in a blank pixel at the node. I wish to get rid of that.
Also i wanted to change the navigation images too. i would like to have the + and - sign images instead of arrows.
Any suggestions?

NM changes icons

Yes, I checked the forum and saw lots of comments about NM changing Icons. Well I uninstalled NM from all machines but it appears that NM uninstaller leaves a lot of junk. I reinstalled it after I turned off all my other machines and to my supprise it showed all the machines that were turned off and the one with the incorrect Icon. Well if all the other machines were turned off I would suppose that they should not show in the map.
I am stumped and guess it was a poor idea to install NM and expect it to show correctly.
Thanks Any way
Frank
Kenmore, WA
Solved!
Go to Solution.

Well hows this. When I starter up my system (2 workstations, 2 cameras, 1 server and one wireless device) all reported correctly by NM. Its as if the entire system reverted back to the orginial systerm and my first installation of NM. I have changed nothing in the system or NM.
Bugs or gremlins in the software?

Add change Icon in the Table Control tool bar.

Hi Abapers,
I need to add "change" icon in the table control. I added it but when I click on it is not working.
My requirement is that when I run my custom report, all the fields should be shown is in display mode. Then when I click on the "change" icon, all fields should be enabled for change.
I have already referred to the standard progs BCALV_* but it does not have the "change" icon.
plz give me any reference prg or sample code.
Thanks
Nani.

Hi Nani,
Track the function code of change icon in user command. if it is clicked then put a flag eq X.
check that flag in PBO, if it is eq X then screen-input = 1 or vice versa.
try this code:
in PBO:
LOOP AT SCREEN
IF WS_EDIT = 'X'
SCREEN-INPUT = 1
ELSE
SCREEN-INPUT = 0
ENDIF
MODIFY SCREEN
ENDLOOP
Hope it will work fine

How to change icon of a Folder-track?

By Folder-track I mean the Folder in Arrange window that is created from "packing reions". Is that even possible in LogicPro7 - to change it's icon?
I mean I know how to change icons for my audio tracks, audio-instrument tracks. And it would be nice if I can assign different icons for different Folder-tracks.
I did not find how to do that

It is possible... use option-command-hold on the icon of the folder in a track in the arrange and up pops the many icons to choose from.
You can set the icon to something other than the folder.
To make different folders I guess you would have to do some image editing
and make your own icons but that is pretty easy.
Put your user create icons here...
~/Library/Application Support/Logic/Images/Icons
and logic will load your numbered image file instead of the default ones that
Logic would normaly use.
Note: 1.png is the file name of the regular folder icon.

Change icon for file type

how to change icon for all of the tile type? not just one, but all!

Changing the file icon will not enable Quicktime to play Matroska files. Changing the file suffix might.
It could be a 'difficult' form of Matroska file. FYI Matroska is just a container like MOV or AVI, and some mkv have the video encoded with Real Video Codec (RV9 RV10). Perian+QT can't decode this, but VLC will play .mkv files just fine on OS X, as long as they don't use H.264!
It's a bit of a lottery until Matroska decide to support the Apple platform. I have found this:
http://mkv4mac.free.fr/index.php?lang=en&p=lec
which may help.
But there may be another workaround: 1. Get Info the mkv file
2. Change to extension to wmv. Save as wmv and that could work better.
Or this link may be helpful:
http://www.squidoo.com/mkv-converter-mac
Recently, a poster (ZachP14) suggested this:
"There's a program called Plex that runs .mkv files awesome on my 2.0 ghz macbook."
http://www.plexapp.com/
Maybe worth a try?

Change Icon missing in the existing SC in ITS URL

Hi Gurus
User is trying to change some details in existing SC, user is able to find the SC in Check status and clicked the details button it will display the document item details, but the Change Icon is missed for the user.
Until last week, user was able to make changes before the cart was approved, also I verified the change details in SU01D, and nothing has been changed.
Also I verified my user ID in testing client, I am able to see the change Icon .
Please advice
Thanks & Regards
Sada

Hi,
Please check the value of the parameter BBP_WFL_SECURITY in trascn PFCG for the EMPLOYEE role. See whether that is set to value low/medium/high so that the employee sees the CHANGE button.

Trouble changing icon in any application, file, etc etc

I've followed the instructions to change an icon and have done it before with success. But it's not working anymore? Here are the steps i'm doing.... Am I missing something?
1. right click on icon that i want to use as the "new icon"
(i believe this is the problem... preview.app is opening the icon. with in get info, the "icon" at the top is just your generic "jpeg" icon. In the "preview" window towards the bottom shows a picture of the icon)
2. select get info
3. right click on "icon" at top of preview window
4. cmd c to copy (also tried copy from file drop down)
5. repeated step on target app to chang icon
6. cmnd v to paste (also tried to paste from file drop down)
doesn't change the icon on the target app or file etc etc....
signed.... confused?

OK, try doing both a SMC and PRAM reset and see if either takes care of the problem.

SMC & PRAM Resets
There are a couple of things you can do before heading off to the Apple store, a SMC and PRAM resets. To do these:
_SMC RESET_
• Shut down the computer.
• Unplug the computer's power cord and all peripherals.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
_PRAM RESET_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
If it still doesn't work then try restarting in Safe Mode, this will clear out some caches which have become corrupted. http://support.apple.com/kb/HT1455

Changing Preferred Language leaves Mail.app's FLAGS menu showing the last non-English language

After changing the System's Preferred Language to FRANCAIS, then back again to BRITISH ENGLISH, I've found that the FLAGS menu of MAIL.APP will not change back to ENGLISH.
e.g.
- I change the Preferred Language setting to FRANCAIS,
- I restart Mail.app.
- I change the Preferred Language setting to BRITISH ENGLISH
- I restart Mail.app.
The Flags menu is still in FRANCAIS. Every other menu is using the correct language
- I then change the Preferred Language to ESPANOL
- I restart Mail.app
- I change the Preferred Language setting to BRITISH ENGLISH
The Flags Menu is now in ESPANOL.
It seems I can change the FLAGS menu to anything other than ENGLISH or BRITISH ENGLISH.
Rebooting between changes and/or leaving Mail.app open or closed seems to make no difference.
It's quite annoying as I make extensive use of keyboard shortcuts to flag emails....!
Any clues?

I should point out that every other menu is changing correctly to reflect the Preferred Language. It is just the FLAGS menu that is not changing to english.

I had to change the visibility of a context node (ZActivityH) to public (it was private) in the context to access it in the method DO_HANDLE_EVENT. I used transaction BSP_WD_WORKBENCH. I verify and activate it.
As a result of changing the visibility, I have this error:
Class      CX_SY_REF_IS_INITIAL
Text:      Dereferencing of the NULL reference
Program:      ZL_CRM_IC_IRECREASON_IMPL=====CP
Include:      ZL_CRM_IC_IRECREASON_IMPL=====CM00C
Source Text Row:      8
The new source code in method DO_HANDLE_EVENT is:
DATA category TYPE STRING.
category = ztyped_context->ZActivityH->GET_CATEGORY( ATTRIBUTE_PATH = '' ).
Any idea about the problem? Can I modify the visibility of a context node?
Thank you very much for your help.
María José

Thanks a lot, Patrick,
My context node is null, but I don´t know why.
I have:
In Class: ZL_CRM_IC_IRECREASON_IMPL
Attribute ZTYPED_CONTEXT     type ref ZL_CRM_IC_IRECREASON_CTXT
In class: ZL_CRM_IC_IRECREASON_CTXT
Attribute ZACTIVITYH      type ref ZL_CRM_IC_IRECREASON_CN10
In class: ZL_CRM_IC_IRECREASON_CN10
Method GET_CATEGORY
In method CREATE_CONTEXT_NODES:
model = owner->create_model(
      class_name     = 'ZL_CRM_IC_IRECREASON_CN10'
      model_id       = 'ActivityH' ).                       "#EC NOTEXT
activityh ?= model.
In view Im filling the context node:
Regards,
María.
