How to expand showDetailItem children
Hi All -
I am facing issue in expanding showDetailItem children when there are more than one child items.
In showDetailItem when I drop my task flow as region it expands well. But when I put one more taskflow region it creates panelGroupLayout containing both the taskflow regions and does not expand completely and shows scroll bars instead.
Could anyone please suggest how can I expand both the regions?
I also tried creating panelStretchLayout inside showDetailItem and putting taskflow regions in its center facet, but here again it will have panelGroupLayout, which is not expanding.
Please note: At a time only one taskflow region will be visible.
Regards -
Rohit
Hi -
I could figure it out. I used the panelSplitter and put one taskflow region in its first facet and other in second. As only one region will be visible at a time both expanded completely.
Thanks for the views :)

How to expand the folder via applescript?
Dear apple experts,
How to expand the folder via applescript?
Manually we are using command + option + right arrow, but how we handle this in applescript?
Thanks in advance,
Velladurai.GHello
Finder's container's "expanded" and "completely expanded" properties have long been marked "NOT AVAILABLE YET" under OSX:
Finder.sdef > Containers and Folders suite
container n [inh. item] : An item that contains other items
elements
contains items, containers, folders, files, alias files, application files, document files, internet location files, clippings, packages.
properties
entire contents (specifier, r/o) : the entire contents of the container, including the contents of its children
expandable (boolean, r/o) : (NOT AVAILABLE YET) Is the container capable of being expanded as an outline?
expanded (boolean) : (NOT AVAILABLE YET) Is the container opened as an outline? (can only be set for containers viewed as lists)
completely expanded (boolean) : (NOT AVAILABLE YET) Are the container and all of its children opened as outlines? (can only be set for containers viewed as lists)
container window (specifier, r/o) : the container window for this folder
A way to expand a given folder is to use keystroke command of System Events to invoke the keyboard shortcut in Finder. Something like the following script.
kLeftArrowCharCode = 28,
kRightArrowCharCode = 29,
kUpArrowCharCode = 30,
kDownArrowCharCode = 31,
--set f to (path to downloads folder from user domain) -- target folder e.g.
set f to (choose folder)
tell application "Finder"
reveal f
tell Finder window 1
set cv to current view
if cv = column view then return -- do nothing
if cv = icon view then set current view to list view
end tell
my _keystroke(it, character id 29, {option down, command down}, 0.2)
end tell
on _keystroke(_app, _key, _modifiers, _delay)
reference _app : application reference
string _key : character(s) to be keystroked [1]
list _modifiers : list of modifier key to be pressed; enumerations are
command down
option down
shift down
control down
number _delay : post-delay amount [sec]
[1] Character must be present on the current keyboard layout. Otherwise, it is replaced by 'a'.
tell _app to activate
tell application "System Events"
tell (process 1 whose bundle identifier = (_app's id))
keystroke _key using _modifiers
end tell
end tell
if _delay > 0 then delay _delay
end _keystroke

How to expand the hierarchy column automatically when delivery reports by a
Hi Experts,
In OBIEE 11.1.1.6.0,how to expand the hierarchy column automatically when delivery reports by agent?
For example:
In SampleLite RPD, when we drag "Time Hierarchy" and Sales column into the report , and sent it by agent ,it will only display "Total" sales, not show all level value,such as Year,Month,Day.So how to expand the hierarchy column automatically when delivery reports by agent?
If we expand all levels and save them, it will be ok, however, when we add new data, it will be collpased automatically and not show the lowest level data, requiring Users or Developer to modify this report for expanding the hierarchy. We think it is very trouble, is there any good suggestion or method for achieving our requirement?958054 wrote:
Hi Dpka,
Is it any difference? I look at the result is same.
Firstly, you said it is 'Add member of ',
Now, you said it is 'Keep member of'
Could you please tell me which options I must select ? Thanks very much.Here is some notes from the documentation to make a better sense of how those two options would work:
•Selection steps — When you create selection steps, you can add a group or a calculated item in a step. Subsequent Keep Only or Remove steps might reference members that were included in the group or calculated item.
◦A group list is affected by members that are kept or removed in subsequent steps, but the group outline value remains the same. For example, suppose the MyNewYork group contains Albany and Buffalo and its value is 100. Suppose Albany is removed in a later step. The value of the MyNewYork group remains at 100, but Albany is no longer listed with the group.
◦A calculated item is not affected by members that are kept or removed in subsequent steps, because removals can affect the components of the formula.
•Groups and calculated items — A step can include a group or calculated item. Groups and calculated items can be used only with Add steps; they cannot be used in Keep Only or Remove steps. -
How to Expand the Screen of Windows Server 2003 on VMware Server 2 ?
Folks,
Hello. Because Windows 7 is not compatible to be installed PeopleSoft PIA, I have to install VMware Server 2 and then install Windows Server 2003, that is compatible with PIA, on the virtual machine.
But when I open Windows Server 2003 on the virtual machine, the screen of Win2K3 is very small, and its size is about 1/4 of the screen of my computer screen. This is not comfortable to work for a long time.
Does any folks know how to expand the screen of Windows Server 2003 on VMware Server 2 virtual machine so that its size covers the entire screen of my computer ?
Thanks in advance !
LucyDid you already installed the VMWare tools onto your VMWare guest OS ? Generally, it helps a lot to be able to redefine a larger screen definition.

I login B2B and click the document link.
The Document Protocols are listed but are not expanded. I have to click the + icon to view the docu I have created and discard the change.
How to expand them?B2B version is 11.1.1.2
I am new in B2B and learing the B2B sample (b2b-101-custom-generic-file.pdf) download from Oracle.
I create Custom (version 1.0 and import the schema file) Document Protocol.
Then, I turn off the PC.
After I trun on the B2B, I find all protocols are not expanded. I need to view the document protocol which I have not finished.
I have to click the Add icon (+). Then the Custom protocol is expanded. But I have to discard the change.
What I want to do is I want all the protocols are expanded automatically after the page is loaded. -
How to set up children usage on my computer?
how to set up children usage on my computer?
First you need to have at least 2 accounts on the computer, yours will be the admin account and each child will have a normal account. While logged in on your admin account, launch System Preferences select the Parental Controls tab. There you'll select each child account and then configure the settings you want to set.

How to add ShowDetailItem to PanelAccordion at runtime (Programatically)?
Hi,
I am creating a PanelAccordion in a popup programatically.
I have add & delete CommandButtons in popup, using which i am trying to add and delete ShowDetailItem from PanelAccordian.
I tried to call a ActionListener on CommandButton to add showDetailItem to Accordion at runtime. But its not working.
This is how i am trying to implement:
RichPanelAccordion contactsContainer = new RichPanelAccordion();
public void BuildUI(){
RichPanelGroupLayout parentContainer = new RichPanelGroupLayout();
// Adding button
RichCommandButton addContact = new RichCommandButton();
addContact.setText("Add Contact");
MethodExpression addEx =
adfUtils.resloveMethod("#{pageFlowScope.contactsBean.addNewContact}",
Object.class, new Class[] { });
addContact.setActionExpression(addEx);
// Adding Accordion
RichPanelAccordion contactsContainer = new RichPanelAccordion();
contactsContainer.setId("contactsContainer");
parentContainer.getChildren().add(addContact);
parentContainer.getChildren().add(addContact);
public void addNewContact() {
RichShowDetailItem contact = new RichShowDetailItem();
contact.setText("New Contact");
contactsContainer.getChildren().add(contact);
System.out.println("::: Add Contact :::" + contactsContainer.getChildren().size());
RequestContext.getCurrentInstance().addPartialTarget(contactsContainer);
}While creation of PanelAccordion, i added couple of ShowDetailItems to it.
After calling addNewContactMethod, its not getting updated with new one.
I tried to get the children of panel accordion while adding. It is showing zero. To access this PanelAccordion in outside, i initialized panelAccordion globally. I think thats y its showing children zero.
How to achieve this requirement? Looking for some ideas.
Thanks in Advance.
Thoom..Hi Thoom,
First of all, debug your code, and try to pay attention if each request you're doing is creating a new RichPanelAccordion (watching the id of instance). If yes, verify your MB scope (pageFlowScope is better) and test your instance before add:
public RichPanelAccordion getContactsContainer(){
if (contactsContainer == null)
contactsContainer = new RichPanelAccordion();
return contactsContainer ;

I have created a PDF exporting the document from word and made it into a form to fill out. When I have created a text box I would like it to expand when there is more words than there is space rather than the text box going into scrolling mode and not showing all the text when printed.
Does any one else have this problem.
Thanks
AvelineWe have tried to manually resize it however it is reliant on the author and how much they would like to put into the document. I will try and set the text to auto and see if that works!
Thank you for your help! -
How to expand a tree at a specific node/item?
Hi,
we have a tree and the nodes/items were binded to context with this code
lo_nd_nvccmp = wd_context->get_child_node( name = wd_this->wdctx_nvccmp ).
lo_nd_tree = lo_nd_nvccmp->get_child_node( name = wd_this->wdctx_tree ).
lo_el_tree = lo_nd_tree->bind_structure( new_item = ls_tree set_initial_elements = abap_false ).
We want that the tree is expanded at a specific node/item?
The structure has the field is_expanded of type WDY_BOOLEAN. I think that if the field of the right structure is 'X' then the tree should expanded. How can we find the right structure in the context and change this field to 'X'?
Code is appreciated.
Thanks, regards
SusanneOh, apparently if you try that call right after you create
the Tree, it will throw a null reference exception. That might
count as a bug in the flex api...
If you create a Tree, and give it's dataProvider some xml
data, and then add it to the stage (addChild), and then you call
expandItem or expandChildrenOf() right after, you will get a null
object exception. You have to wait... for something. I don't know
what.
I even tried calling _tree.invalidateList() before the
expandItem, but it will still throw the error...
I wonder what the Tree needs to wait for? Is this a bug for
Adobe to fix? -
Hi,
I want to expand a MC (talking about the size) from the
middle.
To be more clear.
I have a mc with these properties
_width : 100
_height : 100
_x = 50
_y = 50
I want when I use a rollover function, to change its
properties like this :
_width : 200
_height : 200
_x = 50
_y = 50
The _x and _y have the same values just want to change the
_width and
_height.
And of course, I would like to the tween effect.
How to do this with actionscript ?
Thanks in advance.
StanHi Dave,
I ve tried your bit of code, it seems that it works.. but, as
you ve
mentionned if I want to expand from the center I have to set
-50 to _x and
_y..
In fact, I don't know how to do it.
Here's my code. (it's not pure :-) I m a newbie).
import flash.filters.ColorMatrixFilter;
import mx.transitions.Tween;
import mx.transitions.easing.*;
System.security.allowDomain("mydomain");
var startScale = 100;
var endScale = 200;
var speed = 10;
this.createEmptyMovieClip("my_mc",10);
my_mc.createEmptyMovieClip("container_mc",99);
var mcl_obj
bject = new Object();
mcl_obj.onLoadInit=function(target_mc:MovieClip):Void{
target_mc._height=86;
target_mc._width=115;
target_mc._x=100;
target_mc._y=100;
var myElements_array:Array=[0.3,0.59,0.11,0,0,
0.3,0.59,0.11,0,0,
0.3,0.59,0.11,0,0,
0,0,0,1,0 ];
var myColorMatrix_filter:ColorMatrixFilter=new
ColorMatrixFilter(myElements_array);
target_mc.filters=[myColorMatrix_filter];
target_mc.onRollOver=function(){
this.filters=undefined;
this.onEnterFrame = function () {
if (this._xscale < endScale) {
this._xscale += speed;
this._yscale += speed;
} else {
this._xscale = endScale;
this._yscale = endScale;
delete this.onEnterFrame;
target_mc.onRollOut=function(){
this.filters=[myColorMatrix_filter];
this.onEnterFrame = function () {
if (this._xscale > startScale) {
this._xscale -= speed;
this._yscale -= speed;
} else {
this._xscale = startScale;
this._yscale = startScale;
delete this.onEnterFrame;
var my_mcl:MovieClipLoader = new MovieClipLoader();
my_mcl.addListener(mcl_obj)
my_mcl.loadClip("mydomain/image.jpg");
PS :
The image that I load from the loadClip has a size 640x400
pixels.
That's the reason I resize it to 115x86
My need is :
Display the image with a size of 67x50 Pixels and when the
rollover is
active expand it (from the center) to 115x86.
Any help ??

}you really don't need to post all that code, few people will read it, or try to compile/run it.
just a tree in a scrollpane in a frame is all you need, then add the method/problem to the basic,
and post that so its only 20 to 30 lines long.
here's your basic tree/scrollpane/frame, with an expandAll()
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Testing
public void buildGUI()
JTree tree = new JTree();
expandAll(tree);
JFrame f = new JFrame();
f.getContentPane().add(new JScrollPane(tree));
f.pack();
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
public void expandAll(JTree tree)
int row = 0;
while (row < tree.getRowCount())
tree.expandRow(row);
row++;
public static void main(String[] args)
SwingUtilities.invokeLater(new Runnable(){
public void run(){
new Testing().buildGUI();
}so, is your problem with the expandAll(), or with reading the properties file? -
How to expand rows in a table by calculated value of a field
Hi,
I'm trying to set the rows of an expandable table to follow the calculated value of a field.
The calculated field comes from two date fields that calculate the number of days and I want my table/row to expand based on that number..
Is is possible? Right now I have a button that does add an instance "Admin_Use.Table3._Row1.addInstance(1);" but I want it to be triggered by the calculated field instead...
Thank you so much!!!!Hi Niall,
Thank you for your reply. I'm still a bit puzzled as right now I have this code in my calculate field (see below) under the calculated event and I'm not sure how to insert the code you sent me as I keep getting syntax errors. Any help will be greatly appreciated!!!
if (HasValue(Nights.FirstNight) & HasValue(Nights.LastNight) ) then
if (Date2Num(Nights.LastNight, "YYYY-MM-DD", "en_IE") >= Date2Num(Nights.FirstNight, "YYYY-MM-DD", "en_IE")) then
$ = Date2Num(Nights.LastNight, "YYYY-MM-DD", "en_IE") - Date2Num(Nights.FirstNight, "YYYY-MM-DD", "en_IE") + 1
else
xfa.host.messageBox ("The first night cannot be after the last night", "Nights Covered", 0)
Nights.LastNight.rawValue = null
endif
else

Does anyone know how to expand a backdrop background?
I had a photo shoot for a recital recently and used a cloth backdrop. In some of the images, not everyone was able to fit within the backdrop area. Wanted to know how I could expand the backdrop area in Photoshop so that the images don't look funny. Please help!!
Thank youNot that this will help now, but my first impression when i look at that image is you could have very easily took 2 photos off the wall and used that as your background and cloned out the rail in an instant. next time prepare yourself a little better and have a plan b in place for situations like this. your backdrop looks like it could stretch another 6 ft if the rod was bigger. your composition is not bad,but you should have known you were not going to fit that many on such a small area. maybe change the wall color to more closely match the fabric to downplay the transition.
