JTree without expand/collapse icons

I want to be able to hide or change the expand/collapse icon of a specific node, not the entire Jtree.
Is there any way to do that?

How do I remove the "TOC" btn in the playbar WITHOUT removing the TOC "Expand/Collapse" icon?

I am working in CP7 on a project with a Table of Contents that is set to 'Overlay'. The client has requested that I remove the "TOC" button in the playbar, without removing the TOC "Expand/Collapse" icon, so that the user can still hide/reveal the TOC when necessary. The only control I can find is the "Show TOC" checkbox under Project > Table of Contents. However, un-checking this option removes both the "TOC" button AND the "Expand/Collapse" icons. Is it possible to remove just the "TOC" button in the playbar?

If you are using SWF output you can always edit the playbar in Flash and remove it.
If HTML5 you can edit the JavaScript out put to remove the button from the playbar.

How do I remove expand / collapse icon for JTree empty folders

Hi
I am using a JTree as a file system browser. I use DefaultMutableTreeNode nodes.
I have a problem with empty folders.
Empty folders show the expand / collapse icon, leading the user to believe there are sub-directories. When the user double-clicks the folder, the expand / collapse icon goes away. This is a "haha-gotcha" glitch that I really don't want my users to have to continually deal with.
So, how might I get my JTree to not show the expand / collapse icon for empty folders?
Thanks
Wayne

Maybe I can use the FileSystemView isTraversable(File f) method in my TreeCellRenderer class to check if anything is in the directory.
But I still need to know how to disable the expand / collapse icon for such a node.

Show 'Expand'/'Collapse' Icon in Tray

Hi All,
          I have done the following configuration in the portal and the result is confusing, can you please help me understand why?
1. I have created 2 pages, first is a standard portal page and second a webdynpro page in a test folder
2. copied a standard SAP iView to the test folder and added it to both the pages as a delta link
3. opened the iview property from the std. page and set the "Show u2018Expandu2019/u2019Collapseu2019 Icon in Tray" property to NO
4. opened the iview property from the webdynpro page and set the "Show u2018Expandu2019/u2019Collapseu2019 Icon in Tray" property to NO
When i preview the standard page the iView appears without the "Expand/Collapse" icon, but when i preview the webdynpro page the iview appears with the "Expand/Collapse" icon.
Thanks,
Anand

Remove/hide expand/collapse icons

Hi,
I would like to remove/hide the expand/collapse icons and have a fixed navigation iView.
Thanks in advance.
Rgds,
Janvi

Hi Janvi,
Probably to hide the collapse and expand icon you could go about with the theme editor , where u can set the url to these images as some blank image that coincides with ur background colour.
To have a fixed navigation panel without scrolling ,probably you can change the the width of the navigation panel by changing the value defaultExpWidth in the file WAandNAVPanel.js file in the par file com.sap.layouts.framework.par from 220 pixels to a higher value.Later u need to upload the file back and restart ur system.
Hope this helps,

JTree remove expand/collapse cross button...??

Hi all,
I have forbidden tree collapsing (by default it is fully expanded),
and I want to remove expand/collapse cross buttons that actually are used to expand/collapse tree nodes.
Is it possible and can anyone give me advice how i can do this.
Thanks in advance.

I tried extending the BasicTreeUI to return nulls for the collapsed and exapnded icons as shown in the code below. For the most part, it works great! However, one can still expand/collapse the tree by clicking on the point where the vertical and horizontal lines connect.
I guess some one else will take over from here.

Problem with JTree while expanding/collapsing a node

Hi,
I'm using a JTree for displaying the file system.
Here, i want that whenever a node get expanded,
it should show the latest files/directories under that node.
Now, what i'm doing is, getting all the files/dir's using files.listFiles(),
under that node and then creating a new node and adding it to parent (all in expand() method).
But, now the problem is, while doing this whenever the parent node get expanded its adding all the latest files/dirs into the previous instance
resulting the same file/dir is displaying twice,thrice.. and so on, as that node is expanded and collapsed.
i tried removeAllChildren() in collapse() method but then that node is notexpanding at all .
Can anybody help me please...
i got stuck b'coz of this only.
Thanks...

Now what i'm doing is every time expand() get called,
i'm comparing all the children of that node in the
current instance with all the children present in the
file system (because there is a possibility that some
file/dir may be added or deleted)
is this the right wy or not?it certainly is not wrong, but as usual, there is more than 1 way to implement this...
b'coz right now i'm getting all the files/dirs that
are newly added but facing some problem if somebody
deletes a file/dir.
i'm still trying to get the solutionthen you should not just compare all the children of the node with the files/dirs but also the other way round. compare the files/dirs with the children to determine if the file/dir still exists and if not remove the node.
or you could check if the file which a node represents exists and if not remove the node.

Detailed Navigation (disable expand./collapse icons opening tree

Hi,
I would like to adjust the detailed navigation as this site performs with having no action when clicking the +/- icons.
Please can someone point me in the right direction. I have been able to get the detailed navigation.par file out and look at the jsp code, but not sure where this requires a change.
Will reward points for a helpful answer....
Kai

If I am reading your question correctly, you want to create a detailed navigation similar to SDN so that when you click on the expand/collapse icon it doesn't do a server round trip.
Firstly I believe that the standard one performs a round trip to retrieve the nodes underneath the one that you have expanded.
With SDN we created our own detailed navigation iview so that the entire navigation structure is loaded immediately. This is also the same if you use the standard light navigation iview I believe, so you could simply use this iview instead.
I hope this helps

Expand/Collapse a block in a selection screen

Hey Folks,
I have a requirement , where I have a selection screen, with 3 selection blocks. I have a requirement that I need to make 2 of these blocks expandible/collapsible on the toggle of a button.. How can this be achieved.
In case of a normal screen, I would have had to create the blocks as subscreens (one type of screen for expanded state...another for collapsed state) and called it from the main screen. But how do I achieve the same using the selection screens?
I was considering creating the blocks as subscreens in the selection screen and calling them in the PBO of the main selection screen. However, I am unsure if thats a wise thing to do since the screen is generated automatically in case of a selection screen and I do believe its not a good idea to manually alter it.
Does anyone has any pointers on this?
Thanks and Best Regards,
Puja.

Expand/Collapse option in Portal - SP13

Hi everybody!!
We have EP7.0 NetWeaver 2004s and we upgraded the SP from 5 to 13. When SP13 was installed, the icon to expand/collapse doesn't work correctly (Detail Navigation in Navigation Panel in the Light Framework). The icon always send the user to the main and first page. With the SP5 it works well.
Do you have any idea about how can I solve this??
Thanks in advance for any help that you can give me!
Best Regards,
Claudia

Hi Claudia,
Take a look at this thread maybe it gives you some answers...
How to disable automatic loading of iView/Page in detailed navigation?
We have SP13 at this moment and its working "fine":
1. When clicking on the expand/collapse icon (the triangle) the first navigation node in this folder/workset is NOT loaded automatically.
2. When clicking on the text part of the link (the actual url) the first navigation node in this folder/workset IS loaded.
In addition to step 2 you can steer what navigation node is loaded by setting the parameter "Default Entry for Folder" this property is by default set to No.
Also take a look at the property: "Clicking Folder Name Launches First Node" of the Detailed Navigation iView.. Maybe this is by some reason got set properly...
Good Luck,
Benjamin Houttuin

Expand/Collapse function in WAD 7.0

Hi,
I have made a report in WAD using a table and a chart. In the output which I am running on a portal I have a table Report Navigation with in which I have some of the export options and an Expand / Collapse icons are present on the button group and also I have one drop down box calendar year .As soon as I click on the icon Collapse in the above table Report Navigation my drop down should get collapsed and again when I click on the Expand the drop down should be visible
Report naviagtion and Drop down boxes are present in a seperate table where in when I click on the icons( Expand / Collapse ) it should get reflected on the dropdown box which is present on the 2nd table
I have done the above in WAD 3.5 using Java script Code
How can this be done in WAD 7.0
Regards,
Maya

Hi,
After setting the Analysis item properties, just click on the 7th icon on top menu bar, i think its Verify or Check on server. Somthing like that.
Or try re-opening the template after sometime. Close the existing Web window, where you see your output, and execute the template once again. This should work.
If nothing of the above works, theres one more thing. You may have to re-create the Template.
This happens at times when there is no proper connection between the Portal and WAD. I have faced it myself. So, just try something like that.

Trying to override the default af:tree expanded and collapsed icons

Hi,
I initially hijacked a thread from 2010 that was vaguely similar to what I need to ask, but a kind forum moderator split my post out to stand on its own merits.
I am trying to override the default af:tree expanded and collapsed icons I am using the following styles for my af:tree but they are not reflecting any thing on my tree with the styleclass orgType.
af|tree.orgType::expanded-icon {
content: url("../images/ac-expand.png");
cursor: default;
af|tree.orgType::collapsed-icon {
content: url("../images/ac-collapsed.png");
cursor: default;
af|tree::expanded-icon {
content: url("../images/folder_open.png");
cursor: default;
af|tree::collapsed-icon {
content: url("../images/folder_close.png");
cursor: default;
After working for long hours I realized that there is some problem with af:tree and treeTable. They are not taking the styles where as for the other components, every thing works fine. Is there any way to achieve the task. Could you suggest any alternative way to do this. Thanks in advance. Your suggestions for this task can really help me and my team a lot.
Regards,
Krishna Sumanth.

Hi,
do the icons show without the style class reference used in the skin file? If so, then the style class for this component might be rendered differently for the tree, e.g.
.orgType af|tree ...

JTree with XML content expand/collapse problem

Hello all,
I'm having this very weird problem with a JTree I use to display the contents of an XML file. I use the DOM parser (and not JDOM since I want the application to run as an applet as well, and don't want to have any external libraries for the user to download) and have a custom TreeModel and TreeNode implementations to wrap the DOM nodes so that they are displayed by the JTree.
I have also added a popup menu in the tree, for the user to be able to expand/collapse all nodes under the selected one (i.e. a recursive method).
When expandAll is run, everything works fine and the children of the selected node are expanded (and their children and so on).
However, after the expansion when I run the collapseAll function, even though the selected node collapses, when I re-expand it (manually not by expandAll) all of it's children are still fully open! Even if I collapse sub-elements of the node manually and then collapse this node and re-expand it, it "forgets" the state of it's children and shows them fully expanded.
In other words once I use expandAll no matter what I do, the children of this node will be expanded (once I close it and re-open it).
Also after running expandAll the behaviour(!) of the expanded nodes change: i have tree.setToggleClickCount(1); but on the expanded nodes I need to double-click to collapse them.
I believe the problem is related to my implementations of TreeModel and TreeNode but after many-many hours of trying to figure out what's happening I'm desperate... Please help!

              //for (int i = node.childCount()-4;i>=0;i--){
                   expandAll(tp.pathByAddingChild(model.getChild(node,i)));

Hi,
Iam not facing this problem. To CollapseAll, I do a tree.getModel().reload() which causes all nodes to get collapsed and remain so even if I reopen them manually.
Hope this helps.
cheers,
