Width for List component

I create a List component with Strings using addItem( {
label:some_string, data:some_data } ) in a loop. I want to set the
width of the List based on the width of the widest Item. I assume
the labels must be displayed as TextFields but how do I access the
individual TextFields to get there widths?

That will depend on what layout manager you use and what you constrain the list with.

Need help displaying images with List component for Flash CS4 (ActionScript 3.0)

Hi folks:
I am an inexperienced user of Flash CS4 Pro (v10.0.2). I am attempting to use the List component with ActionScript 3.0 to make a different image display when a user clicks each item in a list.
I did find a tutorial that showed me how to make different text display using a dynamic text box and the following ActionScript:
MyList.addEventListener(Event.CHANGE, ShowSelectedItem);
function ShowSelectedItem(event:Event):void {
ListText.text=MyList.selectedItem.data;
...where My List is the instance of the List component and ListText is the dynamix text box. In this case, the user clicks an item in the list, defined by the label value in the dataProvider parameter of the List component, and text displays as defined in the data value in the dataProvider parameter.
However, as I mentioned to start, what I really want to do is make images display instead of text. Can anyone provide me the steps to do this?
I appreciate your help (in advance)!!
Cindy

Hi...thanks for responding! I was planning on using images from the Library, but if there is a better way to do it, I'm open. So far, I just have text in the data property. This is part of my problem. I don't know what I need to put in the data value for an image to display. Do I just put the image file name and Flash will know to pull it from the Library? Do I need to place the images on the stage on different frames? I apologize for the "stupid user" questions, but as you can tell, I'm a newbie.
Appreciate your patience and any help you can offer!

List of dependent requirements of planned order for a component

Dear guru ,
I search a list of dependent requirements of planned order for a component
What do you suggest ?
Thanks.

Hi Cristano,
Go to MD04 transaction, enter comopenet and plant. Then from the list select the Planned order and click on the Order Report from the bottom tool bar available below the list.
You can see the componets details for that planned order.

Setting a fixed width and a changing height for a component within a panel

Alright guys here's my next question. I'm now having trouble trying to figure out how to only resize the height of a JTabbedPane yet keep the width fixed. In other words, as the JPanel its in changes in size, I'd like to have the width of my tabbed pane stay a certain value yet let the height of it adjust to the panel's height as it changes. Is there a way to somehow extract the panel's height into a int or something and then when using the setPreferredSize() function simply implement this retrieved value into the function's height parameter? I've tried messing around with Dimensions and getHeight() functions and the sort but to no success. For instance, within the constructor of one of my JFrames using System.out.println(this.getHeight()); prints 0, when of course this is not the case in reality for the frame's height. The panel's changing size is due to the user resizing the window its in. In one of my previous threads in this forum I learned how to use a GridLayout (it was 2 rows and 1 column in size) to keep the height of the top area in a BorderLayout fixed, yet as the user resized the window, the layout would stretch the area width-wise accordingly. However, that was because I had 2 cells in the layout to control, and I know this wouldn't work with only 1. Any ideas?

You still apparently haven't read the tutorial on using Layout Managers to understand the capabilites of each Layout Manager.
For instance, within the constructor of one of my JFrames using
System.out.println(this.getHeight()); prints 0, when of course this is not the case in reality for the frame's heightComponents don't have a size until the GUI is visible on the screen. That is until you've done a pack(), or a setVisible( true ). You should never be using setSize().
Layout Managers use setPreferredSize() ,setMinimumSize() and setMaximumSize() as suggestions for determining the layout. Although most layout managers don't use all the suggestions, which is why you need to read the tutorial to find out how the layout managers work.
I'm now having trouble trying to figure out how to only resize the height
of a JTabbedPane yet keep the width fixedWell, I don't understand the requirement. The preferred size of a tabbed pane is equal to the preferred size of the largest tab added to the tabbed pane. So I don't understand the concept of artificially changing the vertical height.
Anyway reread the tutorial on "How to Use the Border Layout". Two of the 5 areas respect the width of the component but alter the height to fill all the available space.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.

Creating search field for a list component

i have created a glossary of terms using the list component and populating it via an XML file.
what i would like to do is create a search field that as the user types in the search bar if there are any matching entries in the list, the focus/selection jumps to that particular item in list. i don't want to clear the list just go to the item that matches.
i would like it to be predictive so if i have these entries:
samson
seek
seether
south
and the user types "s" in the search box to the first "s" entry in the list (samson) is selected, if they type "se" the selection jumps to the first entry with "se" in it (seek) if they type "seet" the selection jumps to "seether" and so on.
i have absolutely no idea how to do it, but more importantly...is this possible?
i have attached the sample files that i have been working on.
thanks in advance

You need the lowercase. the keyCode of the keybpardevent returns the key's uppercase charcode. So the A-key allways returns 65. Therefore convert keycode to char and to lowercase before appending after what's allready there in the field.
To have the user not have to type the words with proper casing, convert the label to lowercase before doing the indexOf search.

List component scroller eventlistener for finished scrolling ?

I have a list component which contains an item renderer. I would like to know if it is possible to detect when the scoller that is built into the List has finished scrolling can fire an event. Is there a built in eventlistener ?

Arrghh, not the right one. I am also moving the scroller bar by using a linkbar to tab the scrollbar to different positions. I need to fire an event when the scroller has reached those new positions. The FlexEvent.CHANGE_END only works when you use the scroller manually.

SAP Design Studio 1.2 sp01 Filters logic is required for drop down list component

Hi all,
I am working with sap ds 1.2 sp01,In dropdown list, assume it has X,Y,Z. So defaulty it shows first "X' value in Dropdown list , but in Croos tab from DS_1, it is not related to "x" value, it shows overall Values In formation,but i want "x" value Information.. How can i get in DS?, PLEASE HELP ME OUT.
.below logics i applied in drop down list component.
DS_1.setFilter("Dimension Name", DROPDOWN_1.getSelectedValue());
and below logic in Application on Startup event:
DROPDOWN_1.setItems(DS_1.getMemberList("dimension name", MemberPresentation.INTERNAL_KEY, MemberDisplay.KEY, 10));
Thanks
Thiru.G

Hi,
Try adding "DS_1.setFilter("Dimension Name", DROPDOWN_1.getSelectedValue()); " after
"DROPDOWN_1.setItems(DS_1.getMemberList("dimension name", MemberPresentation.INTERNAL_KEY, MemberDisplay.KEY, 10));"
on startup event too. You should tell the application that you need to filter the data, even if you don't select it manually from the dropbox, in other words ; on startup.

Java.lang.IllegalStateException: duplicate Id for a component

Hi everyone,
please I'm really having a serious issue on the duplicate id for a component in view.
I have a page of which I used the <jsp:include> tag to add to some pages of my application.
The page have the following code snippet in it

<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

                </h:outputLink>
          </td>
         </tr>
      </table>
</f:subview>The problem is that I always get this exception :

      <h:commandButton type="submit" value="Click Me"/>Yet there is no other component in view with the said id "footerView:homeLink".
So I'm really at a loss on what to do.
Any help will be greatly appreciated.

Hi, I have the same issue.
In my case I have a page that includes one page with richfaces components and if another link is clicked, it includes anotherone without richfaces.
But both included pages contain some identical subpages.
Everytime I call the page with the richfaces components and then the other one I get
java.lang.IllegalStateException: duplicate Id for a component webSourceSetupForm:executionTab:executionTable:executionDayList
     org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:442)
     org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:464)This worked fine before I added richfaces....
The id is even different in both cases. in on it is webSourceSetupForm:executionTab:executionTable:executionDayList in the other jdbcSourceSetupForm:executionTab:executionTable:executionDayList
Did you find a solution to the problem?
Anyone has any idea?
Thank you,

In Flash CS4,How can I give a AS3 List Component a suitable horizontalScrollBar

In Flash CS4 when an AS3 List Component has too many rows,it will has a verticalScrollBar automatically. but it will never has a horizontalScrollBar even a part of the content of the list is hidden.
I set the property list.horizontalScrollPolicy="on",and set list.maxHorizontalScrollPosition=200; then the horizontalScrollBar appear
but when I click the item of the list, all the list move to left, half of the list is hidden,
I can only see the right part of the list, the I click the list again,the list move to right,then I can see all the list by move the horizontalScrollBar
How can I give a suitable horizontalBar to the AS3 list component?

Thank you for your help! (sorry,I`m bad in English...)
In fact, it works.
but,I made a mistake,the reason I want to give a list a horizontalScrollBar is:I want to show all content in a list that is not wide enough,
you see,first row can show all content in this list,but in the other rows,the content is too wide to show,I want to give the list a horizontalScrollBar to show all content by draging the horizontalScrollBar to right.
now,set property:
list.horizontalScrollPolicy="on", list.maxHorizontalScrollPosition=30;(the result is the image above),when I drag the horizontalScrollBar to right:
ah ha ,the row can`t show all content too,the horizontalScrollBar is related to the width of all the list, is not related to the width of the content in every row.
now I kown why the horizontalScrollBar is always disable.
but in design,to show a lot of content,we can`t draw a list too wide, it`s not beatiful,so I want to use a horizontalScrollBar to show all content in every row.
and the list is not too wide
ah ah, like the list in Flex4
In fact,ah,I have not studied Flex 4,so,I have to make it by using Flash CS4 Component
How can I do? Please
(so sorry for my bad English,I do my best in it)

Help with a vertical scroll bar issue with a List component

hi. i have a basic <s:list> that uses an XMLListCollection as it's data provider and a very basic itemrenderer. when a row in the list is clicked a function gets the list.selectedIndex then populates some text fields with more xml data. that all works fine.. the problem i have is that the vertical scroll bar on the list seems to be "clickable" - just like a row in the list. the scroll bar scrolls normally but when it's clicked the selectedIndex becomes -1 which is not helpful b/c the value -1 is passed to the XMLListCollection.
any ideas? cheers.

thanks but still problematic...surely the <s:List> component shouldn't return a value when the scrollbar thumb is clicked? i created a very basic list (see below) and made the list dimensions short enough so that there is a vertical scrollbar and found that when the scrollbar thumb is clicked the trace(event.currentTarget.selectedIndex) returns a number. that's annoying b/c i just want a selectedIndex value for a row that is clicked not the scrollbar.
any ideas to get around? cheers

Displaying Text in List Component

I am using AS3 to load data from an XML document into an Array and use the Array as a dataProvider for a List Component. If I addChild the list to the main timeline, everything works fine. All 38 elements show up in the list with readable text. When I addChild the list into a MovieClip, all 38 rows of the list get created, but no text shows up. What the hell is going on? Does anyone know what the fix for this is and why in the world this is happening?
Here's my code:
TOCList = new List();
TOCList.dataProvider= new DataProvider(TOCArray);
TOCList.labelField="theLabel";
TOCList.y=75;
TOCList.width=250;
TOCList.height=350;
addChild(TOCList);
When I change the addChild(TOCList) to navBar.sceneMenu.addChild(TOCList) the list shows up formatted correctly, just no text.

I figured it out with help from another web site's forum and the problem was that the MovieClip that I was loading into was masked, so the font needed to be embedded and my code...
     var myFormat:TextFormat = new TextFormat();
    myFormat.font="Tahoma";
    TOCList.setStyle("embedFonts", true);
    TOCList.setStyle("textFormat", myFormat);
...wasn't working, but I didn't know, because the text wasn't showing.
The fix was actually to use the StyleManager...
StyleManager.setStyle( "textFormat", new TextFormat("Arial") );
StyleManager.setStyle( "embedFonts", true );
...to force all components to this style.
I have no idea why the above code doesn't work. If anybody knows, please tell me!!!

How can I select an item from a list component with a seperate button

This is a repost, I decided it'd probably be better here than
in the general discussion board. I will try to delete the other
one.
Hello Everyone,
This is my first post here. I am trying to figure out how to
select an item within a list component with a button. This button
is calling a function. I have searched for the past 3 hours online
and I can't find anything about it. I thought perhaps I could set
the selectedItem parameter, but that is read only, and I believe it
returns an object reference rather than something like a number so
even if i could set it, it would be pointless. I also found a get
focus button, thought that may lead me somewhere, but I think that
is for setting which component has focus currently as far as typing
in and things like that. I am lost.
Basically I am looking for a way to type this
myList.setSelected(5); where 5 is the 5th item in the list.
Any help would be much appreciated.

Never mind found it. It is the property called selectedIndex
and it is writable
