JTree custom icon help

Hi, i am trying to get custom icon for specific nodes of a tree. In my customTreeCellrenderer that extends the default predecessor, i have this function. The problem is that, the icons are not set to the node i want but the node after that node. Anyone got any suggestions as to what i am doing wrong ?
Thanks, Dave
     public Component getTreeCellRendererComponent(JTree tree, Object value, boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus) {
          ImageIcon error = new ImageIcon("illegal.gif");
          super.getTreeCellRendererComponent(tree, value, sel,expanded, leaf, row,hasFocus);
          DefaultMutableTreeNode node = (DefaultMutableTreeNode) value;
          GroupNodeObject obj = (GroupNodeObject) node.getUserObject();
          if(node.getUserObject() instanceof GroupNodeObject){
               if(obj.isIllegal()){
                    this.setLeafIcon(error);
                    this.setClosedIcon(error);
                    this.setOpenIcon(error);
               }else{
                    this.setLeafIcon(getDefaultLeafIcon());
                    this.setClosedIcon(getDefaultClosedIcon());
                    this.setOpenIcon(getDefaultOpenIcon());
          return this;
     }

may be the next node is instance of GroupNode!!
just incase, check the code if the error is assigning the nodes!
This code looks ok.

Jtree leaf custom icons

I created my own class that extands DefaultTreeCellRenderer and overrided the function getTreeCellRendererComponent.For now I see the customed icon on the leaf,but when I touch with the mouse the panel the vision of the leaf comes back to default.I tried to do repaint it's doesn't help me
May be you have any suggestions?

ok I did the following code in a previous project to handle a similer requirement

Help, how to make Finder to refresh custom icon programmatically

Hi
I have two file both are same name, e.g. 1.rtf, but with different custom icon.
When I copied the first 1.rtf to an USB drive, the custom icon was displayed correctly.
However, when copied the second file to the USB drive to replace the first file, Finder still showed the custom icon of the first file.
How can I solve this issue and how can I make Finder to refresh the custom icon programmatically.
Thanks

Hi KT, thanks your reply & help
but result is same. The following is my experiment
STEP 1: copy 1.rtf to USB drive, the result is OK.
STEP 2: copy another 1.rtf to USB drive, Finder still showing the 1st file icon and a little bit blurred
STEP 3: copy 3rd file without custom icon, the result is OK
STEP 4: using following code to set its custom icon, the result is still show the custom icon of the 1st file
[[NSWorkspace sharedWorkspace] setIcon:image forFile:[filePath stringValue] options:nil];
It seems that Finder will has some cache to store file's custom icon. If use "Force Quit" to relaunch Finder, it become correct but how can I use program code to refresh it without "Force Quit"?

Help my buddies custom icons dont show up only the aim guy does

idk y but my buddies custom icons dont show up anymore only the aim guy does eomoen plzzz help me

If you have more than one iChat account, like a mac and an AIM screen name, each of them only displays the buddies and their details that you have added whilst logged in with that account. You can check quickly if your other account displays the list as you were expecting by selecting the iChat drop down menu>accounts and check if you have more than one.
If not, please post again.
This is always handy to trouble shoot:

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.

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
The copyright and javadocs information has been stripped for clarity.

Mystery of the Disappearing Custom Icons

iMac 2.66; 10.6.4
I create simple custom icon labels for the docs & folders in my dock. I type a filename in TextEdit, take a screenshot of it, open the screenshot in GraphicConverter, and copy & paste it into the getinfo window of the doc or folder. Then I drag it to the dock. Now and then, with no pattern or seeming cause, the custom icons on one or more disappear. Some never disappear. Sometimes it'll be weeks with no problem, sometimes hours. I repair permissions twice a week without fail. I have no other issues going on. Anyone know why this is happening? I've searched the fora but can't find similar problems.

Trouble with some documents: no custom icon, only generic appears

I tried anything: rebuilt launch servcice, permission repair, daily, weekly, monthly scripts (using maintanace, onyx, etc...) BUT all the documents associated with Openoffice have no custom icon. I also tried reinstalling oo with no success. It happens with textedit and keynote (using "get info", open with, apply to all) and don't know why?
Can anybody help me?
Thanks!

You could create a new admin user and move the data within each of these folders to the corresponding folder on the new account: Desktop, Documents. Library, Movies, Music, etc. You can di it most easily IMO, by copying your Home folder to DVD first. Alternatively, you could use Users/Shared for the data.
But it would really be best to sort this issue in your present user.
It would be a good idea to test with a new user though to see if the problem exists there.
Create a new account, name it "test" and see how your OO & TE work in that User acct? (That will tell if your problem is systemwide or limited to your User acct.) This account is just for test, do nothing further with it.
Open System Preferences >> Accounts >> "+" make it an admin account.
Let us know and we'll troubleshoot this further.

Custom icon lost from dock when clicked.

Hello.
I'm currently running OS 10.6.1 on 15" MBP w/ 2.4 Ghz Intel Core 2 Duo, 4 GB RAM. I experienced this same issue in Leopard, but was hoping Snow Leopard would fix it. I thought it did, but it just happened again.
I keep several documents in the dock that I use very frequently (three MS Excel workbooks, 1 FM Pro database). For some reason, when I click on any of the Excel docs, the custom icon I have assigned to it is lost. Even when I reveal in Finder, the icon has just been removed, and the standard Excel icon shows.
The funny thing is that the custom icons, when replaced, seem to last for several clicks, then for some reason, they just go away when the doc is clicked.
Has anyone experienced this issue? Any help would be awesome.

Hi eye sean,
The program icons on your Dock (App Store, System Preferences) are alias links (shortcuts) and not the programs themselves. You can't delete them by removing them from the Dock. Now, if somehow they were accidentally removed from the /Applications folder then that's a bigger issue. I take it neither of the programs or in that folder?
If that's the case there's two things I'm aware of worth trying:
Run a repair Disk Permissions from the installation disc that came with your computer
Reinstall the Operating System via the installation disc
If System Preferences (the application) is completely gone, then it's option #2. If it's corrupted the disk permissions may resolved it. I'd say you could make a new user to see if a preference pane that's specific to your current user is causing problems, but without System Preferences access that's not really a valid option.

Custom Icon Not Appear in iTune

I am ready to submit my apps but I am stuck because of one simple problem that I cannot solve.
When I go through Project > Export Release, the custom icon does not show up in iTune, but they are shown in my iPhone, iPod and iPad
The default icon appears in the iTune but not the one I designed.
I have already included the all the different size icons to your build (29, 48, 57, 72, 114, 128 and 512) and see if that solves your problem but this did not solve the problem.
Please help me!
Thank you very much.

Hi,
I have tried setting 512x512 image in the app.xml and i was able to get the icon image in iTunes.
If you are using the same icon file in AIR and embedding it to set it dynamically at runtime then you might have an issue. In this case, please create a copy of same image and use it in app.xml file.
Let me know if this helps.

Custom Icon for application file

I can make director allow me to have a custom icon for appliacation file.
In director I have attempted this several times where I have tried to have my appliaction file have an icon. I have purchased two icon program Candy Bar and Fastincs trying to remedy this problem.
As you see here I am using an ins file created in Fastincs. Now here is an image to the path and the icon itself Applipcations/ Adobe Director 11/3 HorseLogo.mac.ins
So there is the setup now when I complile for my program file I get this.
See the grey Director icon I don't want that I want the three horse logo.
I also tried to assign the logo after publishing the file.
then I drag my icon file in
The program created in director still wont see the icon file.
If I use Candy bar (icon application) I get a different result. The icon works
in both finder and on the task bar
This is exactly what I want.
I works until I try to move the entire package into an installer program I am using BitRock. When I compile the installation program then try to run the application I get the following message
If I choose ignore the install continues. But I have no icon.
I am desperate , weeping , screaming , and almost a lost cause, any help any help at all I could really use.
Thanks
Robin aka innish

Hi Robin,
I'm more of a PC person rather than Mac. I would recommend you look at the Resource and Icon Editor page at:
http://collab.directorforum.com/Resource_and_Icon_Editor
It may fix your icon issue from Director.

Custom Icon problem

I had a friend make me a Custom Icon of an Apple and a custom Firefox logo blended together and i wanted to use it to show as my Firefox App Icon.
I went to get info on the FFox App. and made the exsisting Logo area turn BLUE as in selecting it and dragged the new 256x256 icon to that area. The icon went in ( the Green Plus was showing ) and when I checked it was an Icon of PREVIEW's Icon now I can't get rid of it. I even took the new icon and put it in the FFox Resourses folder and named it firefox.incs, re-named the old one by just addig a 1 to it's name. Then I re-booted and still the same old PREVIEW's icon is still there . How can I get the Icon I want to go there ? I even used Candybar icon changer. I need HELP with this PLEASE, it's driving me nuts. OH Yeah, I'm useing Snow Leopard 10.6.7 on a MBP laptop.

Hi, Mike -
Instead of dragging the icon you want to the icon box in Get Info, use Copy/Paste.
First copy the new icon to the clipboard:
• if it's already an icon for a doc or folder, do a Get Info on that, click the icon in the Get Info window (at the top, not in the Preview section) to select it, then select Copy from the Edit menu (or press Command-C).
• if it is in an image file, open that file and select the image, then select Copy from the Edit menu (or press Command-C).
Then do a Get Info on FireFox, click the icon in the upper part of the window to select it, then select Paste from the Edit menu (or press Command-V).

Custom Icon can be loaded from search directory

Currently Custom Icon can only be placed under
C:\Users\Public\Documents\National Instruments\TestStand 2014 (32-bit)\Components\Icons
and
C:\Program Files\TestStand 2014\Components\Icons
and also from
search directory option for icon (New Idea)
If icons can also be loaded in path mentioned search directory, It help a lot in handling things among a large ATE Team (50 Test Developers)

I made the zip file with WinZip in the same directory as the class file,
as directed by the previous thread, and uploaded it to my server.
It still does not load the applet.
Here is my webpage:
http://www.geocities.com/shaolin_bi/scopeApplet.html
Can someone please take a look and tell me what I am doing wrong?
Thanks.

Black Boxes Behind Icons– HELP!

Hi! I like making my own icons and then taking IconComposer (Developer tool) and having it make me a icns file. It works great, except anytime, yes anytime, I put any kind, ANY kind of custom icon on anything, instead of the background of the icon being transparent (alpha channel,) I see a big black box behind everything. If there isn't something on every one of the 32 or however many pixels in my icon, black shows up. HELP!!!!

OOPS! I must not of turned voice over to "off" as previously suggested. All situations resolved.
