Creation of a Popup Menu for a Tree Node

Hi Ppl,
I need to create a Pop-up Menu for a tree node in WebDynpro Application, please give me a "How to .." sort of material or a link which would have same sort of information...
Also, My requirement is to call the pop-up on the right click of mouse on the tree node, please let me know on which event handler I can call it ? Do I require a custom event handler for it ?
Thanks in advance

Hi Anish,
You simply add a Tree UI element, and then right-click the tree UI element and insert a TreeNode element.
To the TreeNode element you can add a menu, and then to this menu you can add menu items. When the user right click the tree node, the menu item is displayed. If the user clicks the menu item, the action for the menuitem is run.
Hope that helps.

Queue for Binary Tree Node

I need to create a simple Queue class for Binary Tree Node. The class consist of only enqueue and dequeue, I cannot use the Collection Interface though. But I have no idea how to do it. Below is my Binary Tree Node Class.
public class BTNode {
     private customer     item;
     private BTNode     left;
     private BTNode     right;
     public BTNode() {// constructor
          item = null;
          left = right = null;
     public BTNode(customer newItem) {// constructor
          item = newItem.clone();
          left = right = null;
     public void setItem(customer newItem) {// set methods
          item = newItem.clone();
     public void setLeft(BTNode newLeft) {
          left = newLeft;
     public void setRight(BTNode newRight) {
          right = newRight;
     public customer getItem() {     // get methods
          return item;
     public BTNode getLeft() {
          return left;
     public BTNode getRight() {
          return right;
public class Queue1 extends BTNode {
    public Queue1() {
        super();
    public void enqueue(BTNode newItem) {
    public void dequeue() {
}

public class Queue1 extends BTNode {Why do you think that the queue should extend BTNode?
You probably want to aggregate a List.

I did an extensive search in this forum, but i cudnt find the answer i am looking for.
I am using Normal Dialog screen in which user validate the screen and hit the save button.
I need to show this values in Pop-up ( I have called the FM reusee alv_grid_display).
In the display one of field is editable and i am showing F4 help for the editable field.
User clicks any value from F4help, i need to store the value selected in my custom table .
User command does not register that event.
How to register that event when user clicks the f4 help, i am getting F4 help already and able to select the value too.I
need to store that selected value.
Please dont recomment using OO already i have used the classed for display and again calling nornal diaglog screen and for validation i need to call pop-up in same screen ( Used alv FM screen ).
Please let me know your answer ASAP.

Thank you very much,
during testing I have recognized, that the buttons in the toolbar are new functions, because of the edit mode.
So I have put all the new button into the excluding list. It worked!
Thanks again!

Possible Issue with help for "disable property node"

Hi, In Labview version 9.0 (32-bit) there seems to be a conflict between help info for the Enum constant as applied to the disable property node . If I right click on a control variable and select create-> property node -> disable. If I then right click on disable -> help for disable, the help lists the following interger assignment 0 - Disable, 1- Disable and Greyed, 2 Enable. If however, I right click on the generated Enum constant and select properties -> Edit Items, the listing order is as follows; 0- Enable, 1- Disable, 2- Disable and Greyed. The latter assignment is how the Enum constant actually works. It appears that the help information may be incorrect.
Regards,
Pat
Solved!
Go to Solution.

Hi,
I compared it with 8.2.
In 8.2 creating a constant, indicator or control by right clicking on the "disabled" property node gave an object of type U8, which operates in accordance with the "help for disabled", ie
0=Enable
1=Disable
2=Disable/grey
In 9.0/2009 right clicking and creating on the property node gives an Enum (of datatype U8) with names/values in agreement with 8.2, and operation as in 8.2, BUT the "help for disabled" message says
0=Disable
1=Disable/grey
2=Enable
Thus I would agree that this is a documentation error, and the LabVIEW is correct.
N.I. Can we have a CAR please?
P.S. I do think that it is a good idea to have made the disabled property an enum, whilst maintaining compatability with previous code. I always wondered why it wasn't that way in earlier revisions.

Need coordinate for particular tree node as currently expanded

Hi All,
i am working in flex for the past two months,currently i am
working on the drag and drop on a tree , where i am able to drag
one tree leaf node to another another tree leaf node and i am able
to draw a line between the two leaf node indicating that this has
been dragged from the previous tree of a particular node to the
current node of the tree.
The problem which i am facing is that when i collapse the
expanded tree , the line which i have drawn is not able to
synchronize with the tree expand or collapse (the line remains in
the same position even when the particular leaf node move down coz
of expansion of the above tree node.)
any help will be appreciated.

there is a private function in the tree.as class:
private function getVisibleChildrenCount(item:Object):int
that I can use by multiplying how many children there are by
how tall each item "physically" displays on the screen as, but I
want to get that publicly. I don't want to go about hacking the
tree.as code, that's poor form in the highest. Does anybody else
have any ideas...
please?

Setting Background Color for a tree node

I have the following code
====================================================================================
public class IconNodeRendererClass extends DefaultTreeCellRenderer {
//* getListCellRendererComponent

public Component getTreeCellRendererComponent(JTree tree, Object value,
boolean sel, boolean expanded, boolean leaf,
int row, boolean hasFocus) {
Component c = super.getTreeCellRendererComponent(tree, value,

ImageIcon icon = ((IconNodeClass)value).getIcon();
if (((IconNodeClass)value).isRoot()) {
c.setBackground(Color.blue);

====================================================================================
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);
}

JTREE request edit mode for one node

hello,
my jtree is editable
tree.setEditable(true); // double click on a node and it goes in "edit mode"
I would like to set a specific node into "edit mode" (just like when you create a new folder in windows - new folder appears in edit mode - you just have to type the name of the folder)
//set the node selected
setSelectionPath(new TreePath(newfolder.getPath()));
// set the node in edit mode - does not exist ???
setEdit((new TreePath(newfolder.getPath())); ????
Second question:
how can I avoid a specific node from being editable ?
// set all the nodes editable !!
tree.setEditable(true);
thanks a lot !

Lightroom: in edit mode capabilities disapeared?

Lightroom: in edit mode capabilities to modify disapeared: firs to do the sharpening and then contrast… ? How can I get all functions back?

Dear Larry and Terence,
Love you guys!
Okay, I now understand that iPhoto is continually re-modifying my portrait shots, following the flags my camera is applying. So the real test of whether going into Edit Mode modifies JPEGS comes with landscape images. So, I do this:
1) Choose a definitively un-modified landscape JPEG
2) Open it in Edit Mode
3) Zoom
4) Click Done and return to View Mode
5) Check for the "Revert to Original" option
6) Find it is not enabled
7) Breath sigh of relief
8) Bow to the wisdom of the Mac Gurus
Hooray! As it should be, no degradation of JPEGS here. I'm still annoyed that I have to go into Edit Mode to zoom in on images in the first place, but then I'm annoyed by having to watch my calories to avoid getting pudgy, so I can't blame Apple for all my problems.
Thank you again. Oh, and I'd love to give you both "solved" points, but I can't, so I gave Larry a "helpful" first and will give Terence a "solved" now. Not fair, Larry, I know. Sorry. But you know you both rule.

How to get out of tex edit mode with a single button?

Hey,
Is there a way to escape from text edit mode with a single click or button?
So far I always hit CTRL+Enter, then V and then I click away from the canvas so that the paragraph ain't higlighted no more. But thats a pain in the butt! Cant there be a single button for this?
Thaks

Something interesting I just noticed: Double-clicking outside a text box can have different effects according to context.
With the Pointer tool selected, double-clicking on a text box allows you to edit the text. In this "quick edit" mode, double-clicking outside the text box will return you to the Pointer tool.
If the Text tool has been selected manually, double-clicking outside a text box will create a new text box.

Search Help for Hierarchy Node in SAP BW 7.3

Hi Experts,
We were previously using SAP BW 7.1 system and we had a table which used to be maintained through SM30 which has a customed search help on one of the fields for a hierarchy object. And it was working perfectly.
However, one of our systems have just been migrated into 7.3 version and the above functionality is no longer working.
This is what is happening now:
- User selects a hierarchy and after selection nothing is being displayed on field on the table.
We have tried to debug this customed search help in both environments to distinguish what is wrong. We have noted that a standard function module (RRSV_IOBJ_VALUE_OUTPUT) is not behaving similarly. In 7.1 system, the C_T_DATA table is being filled whereby in the 7.3 system, it is empty.
Do you think this is the issue?
Please do advise and propose what can be done to make it work. Or any idea on how to create a new search help for a hierarchy node in 7.3?
Thanks in advance.

hi,
one more thing i will like to add here is in BW 7.3 you get a new security admin feature that allows you to make mass changes to authorizations instead of one-by-one. This can be done by cut-and-paste in a worklist, hierarchy nodes, and you can also add users to multiple analysis authorizations.
The u2018newu2019 authorizations has both the data value and hierarchy restrictions. You can still build using the u201CRSECADMINu201D transaction
Also make sure that all objects are in the TLIBG library and they will be 'shielded' during the upgrade.

So how can I programmatically start editing?
Thanks a lot, DreamiX.

ALV GRID edit mode keyboard issue

Hi,
I have created a program that displays an ALV GRID.
From the Layout I said to edit in edit mode the ALV Grid.
In the menu toolbar I exclude the button 'cut - copy -paste and delete line'.
When I run the program I see that these buttons are not displayed --> OK.
BUT my problem is: if I use the keyboard then the ALV Grid manages these actions.
For instance. I select some lines and press the key DELETE on the keyboard --> the lines are removed and that is not that I expect because I removed this action from the toolbar.
For the cut - copy and paste it's the same.
Do you have a solution for me --> intercept an event or change the function keys or ....
I would like that the ALV Grid does not manage the keys delete, CRTL-C, CRTL-V in edit mode.
Thanks,
Stevie,

Hi Steve
I was not aware of this. So, I recommend you to try this:
At the event "before_user_command" you can terminate the process by resetting the ALV user command.
e.g.
 CASE e_ucomm .
 WHEN '&INFO' .
 CALL METHOD gr_alvgrid->set_user_command
 EXPORTING i_ucomm = space.
 ENDCASE .
This code within the event overrides the '&INFO' function and terminates its process. For cut and copy, you can find out ucomm values by putting a break point inside the event and tracing the value of "i_ucomm".
For some relevant issues, you can inspect the tutorial <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/an%20easy%20reference%20for%20alv%20grid%20control.pdf">"An Easy Reference For ALV Grid Control"</a>.

Can't get my audio clip to work in Keynote except in edit mode. I've followed Help instructions to the letter. Any suggestions?

Can't get my audio clip to work in Keynote except in edit mode. I've followed Help instructions to the letter. Any suggestions?

Hi Gary - thanks so much for your help. I'd already done that, but finally stumbled across the answer for my situation. I'm new to iMac and this is the first time I used Keynote, so maybe this info will help someone else along the way - I still haven't found this in any of the Keynote documentation or forums I've read.
My slides were all set up with at least one text box in which the text was animated. The sound was the last thing I added to each slide, exactly following the info in Keynote Help re: adding audio. The audio would work when I tested it in Inspector mode, and also if I switched to soundtrack instead. But not if sound was added to each individual slide. Hmmm. After I submitted the question above, I was running through the (auto) slide show one final time to check text, animation, etc. when I noticed that on just one single slide the sound effect came through, but at the very tail end of the slide. Hmm again. Why?
Through trial & error, the answer was in the animation section - not very intuitive re: audio. The steps to correct the issue were: 1) click on the sound icon embedded in each slide, 2) click on the animation tab in Inspector. 3) There's a drop-down menu there that allows you to reposition the audio clip to the #1 spot (if it was added after other "animation"). This allows the sound to begin before the text animation begins on each slide. Before doing this, I guess the sound was in there but the slides were transitioning before it had a chance to play.
Since this is the first time I've used Keynote and it's the most recent version, I'm not sure if this is a new feature to allow users to choose where within a slide to play a sound effect, but I'm guessing that might be why was unable to find any info on how to solve it. Hopefully this will help others who get stumped.
Thanks again for jumping in to help! I really appreciate it.
