ChoiceBox and ComboBox

Hi all,
I am using Scene Builder and I have two questions about Choice Box.
1) What is the difference between ChoiceBox and ComboBox? It seems both have same features and functionalities
2) How to change default item1, item2, etc, font style and size on a ChoiceBox or ComboBox from SceneBuilder? I see I can set my own custom items names from FXML file but I would prefer to accomplish from SceneBuilder if possible.
Thanks
Alberto

1) What is the difference between ChoiceBox and ComboBox? It seems both have same features and functionalitiesThe difference between a ChoiceBox and a ComboBox comes down to the method of display: a ChoiceBox uses menus, a ComboBox uses a ListView.
A ChoiceBox well-suited to a small number of choices
A ComboBox well-suited to a large number of choices.

Refresh and combobox

Hi all,
I need to develop a really small add-on for a client. This add on is suppose to handle this action:
When the user clicks on add when he is on the BP master data screen, the add-on will create a project code based on the BP Code and select the new project code in the combox before adding the BP.
Everything is working expect selecting the new project code before adding the BP. One of the issue is that I can't see the new project code until I reload the screen (I tried with a refresh but it does not work).
The second issue is that I don't know how to select my new project code in the combox. Can anyone help me?
Vincent
Here is the code if you think you can help me:

    Case et_ITEM_PRESSED:

You can select an item in the combo box as follows:
Set sboCombo = sboForm.Items("222").Specific
sboCombo.Select "My Project", psk_ByDescription
I think you will not be able to see your new project in the list due to the timing of when the list is populated. It would probably be easier to simply update the BP record using the DI after it has been added to the database. (et_ITEM_PRESSED, before_action = False).

Data Binding using DataSet and ComboBox

Hi guys, hope someone can help me with this. Seems it should
be simple, but it's not, that's why I'm here. I have data loading
into a DataSet component. I have a ComboBox on the stage with
predefined values and lables, so it's not dynamic at all. After
loads into the DataSet I have the value Bound to the the Combobox,
but nothing is being selected. I know the ComboBox is a little bit
trickier, unlike the Textfield or TextInput wich work right away.
Again, hope someone can help.

Thank you !

Hello Huynh,
As I mentioned before, the simplest solution for your requirement is UDO, therefore you don't need to rewrite the code of update, people here rarely rewrite the update logic of the form, instead just reuse the default implemenation of update in B1. The only magic is databind in your form. You can use UDO Form Generator in B1DE to create the form for you. Form/DataBind has been done. Then the browse, update function has been done by B1.
Also think about the flexibility of design, what if the employee has more than 5 children.
1. Create your own UDT and UDO instead of UDFs in OHEM, thus you can use UDO, you don't need to do with Add, Update.
Example: your UDT can be like this
AMI_OHEM : U_EmpID (This field works a link to EmpID in OHEM, just forget the UDFs in OHEM)
AMI_HEM1:   U_Child, U_DateOB, U_*** (Child Table, a matrix of children, support as many as children, just set the valid values for U_***, then it will be generated as comobox in UDO form by UDO Form Generator, by the way the children grid view will be generated as matrix, not grid in the udo form generator.)
2. Use UDO Form Generater in B1DE to generate the form.
3. Open this UDO form when click the view children button in employee master data form.
This is the right way. Hope it is clear
Kind Regards

HTML component blinking cursor and combobox problems

Hi there.
I have a problem using a website displayed with the HTML component in a spark window. In any textfield in this homepage there is no blinking cursor displayed which is not really a problem but is still pretty confusing to the users. Another issue comes up with the comboboxes where the possible choices cannot be clicked with the mouse. Choosing an entry with the keyboard is possible though.
To reproduce this issue, add a html component in a spark window and load for example http://www.ard.de. The cursor is blinking in the search textfield in the top left. After clicking on the combobox on the left side - where i can't choose an entry with the mouse - the cursor in the textfield is no longer displayed.
Is this a known issue?
Best regards

Hi,
I've looked at your example and found the following 2 issues:
1. The cursor not appearing was actually a focus issue and you can fix it by adding an event listener on "windowActivate" in which to re-set the focus to the _htmlWindow. See the code below for more details on "onActivate()"
2. The issue with the dropdown is actually a bug (internal bug id #2721855) and it has been fixed in the next version of AIR which will be released towards the end of this year.

OIM: Question about LookupField and Combobox

Hi,
I have a lookup field and it is configured in the form as a Combobox. This field is optional and so I want to display an empty string as the default selection in this combobox. I am not able to do that as the Lookup CodeKey is not taking empty value/string. Instead the first choice shows up for all such fields and it is really not the right choice. Is there a way to show empty string in combo boxes?
Thanks in advance

there is no way to do that. I had similar issues. The method I adopted was to modify the OIM JSP so that when the values from the bean is extracted, I add the "Select" option to the list and then display to the user.
Which form/resource you want to achieve this functionality so that I can guide with the JSP you need to modify?

Tab with Cellrenderer and Combobox

When using Cellrenderer to display a combobox in a datagrid, there is an issue with using Tab. If you tab through the cells, it will cause the combobox to erase. To fix this the column needs to be set to non-editable. Problem with doing this is that then you cannot tab to the cell where the combobox is.
Does anyone know a work-around this?

Had you RTFA you would have learnt that JTable uses Renderers in the same way you would use a
rubber stamp... thus each header is NOT a seperate Component, but the same component simply
used to paint it....
Following on from this... you may have now what looks very much like an active combo box, this is
just fooling you. It is merely a ghost of a combo box.. some pixels on the screen, nothing more..
First and foremost, before running around in desperate circles - RTFA

Embedded font and Combobox

Hello All,
Scenario of my application: Application have combobox filled with fonts list. When user select font from combobox. Application load font swf from server and apply to text.
I have embedded fonts in SWF using css.
@font-face {
    src: url("assets/fonts/arial.ttf");
    fontFamily: "Arial";
    fontWeight: "normal";
    embedAsCFF: true;
here is code snippet to load font from server.
var eventDesi:IEventDispatcher = styleManager.loadStyleDeclarations2(fontStyleName.@swfURL);
            eventDesi.addEventListener(StyleEvent.ERROR,function(event:StyleEvent):void{
                Alert.show("error while downloading font " + fontStyleName.@name);
            eventDesi.addEventListener(StyleEvent.COMPLETE,function(event:StyleEvent):void{
                fontStyleName.@isDownloaded == "true";
               if(functionToCall != null)
                    functionToCall.call();
Problem:
When I select font arial form combobox all list of fonts,tool tips are get disappear. My primary exploration is combobox has arial font and I am loading again arial and registering it. This may be the cause.
Is there any way to set embeded font to any control?
Thanks,
Vikram

Hi,
Follow this tutorial and use the code below..
http://www.designscripting.com/2011/06/as3-combobox-font-embedding-problem-flash-cs5/
var arial:Font = new ArialFont();
var myFormatBlack:TextFormat = new TextFormat();
myFormatBlack.font = arial.fontName;
myFormatBlack.size = 18;
myFormatBlack.color = 0x000000;
myComboBox.textField.setStyle("embedFonts", true);
myComboBox.textField.setStyle("textFormat", myFormatBlack);
myComboBox.dropdown.setRendererStyle("embedFonts", true);
myComboBox.dropdown.setRendererStyle("textFormat", myFormatBlack);
myComboBox.setStyle("embedFonts", true);
myComboBox.setStyle("textFormat", myFormatBlack);
myComboBox.prompt = "Select State";
myComboBox.width = 248;
myComboBox.height = 25;
myComboBox.x = 100
myComboBox.y = 100
myComboBox.setStyle("textPadding", 1);

About dropbox and combobox widgets and variables

This is a two-part problem.
First, I wanted to use a combo box (or drop box) widget to insert a field that can be populated by choosing one of six options (A through F). The variable that gets populated is called 'a'. On the slide, there is the drop (or combo) box and a button that executes an advanced action. In the advanced action, It goes:
IF variable 'a' is equal to 'A' go to slide x.
ELSE go to slide y.
No matter what option is chosen on the combo (or drop) box, nothing gets assigned into the variable. I tried this with both widgets. I finally ended up using a textbox and asking the user to type the correct option into the text box.
Which leads me to the secont part of the problem. The textbox is associated to the variable 'a'. The correct answer is 'A'. The advanced action is the same as above. However, if I want to make the correct answer lower-case 'a', the advanced action ALWAYS evaluates as false and executes the 'ELSE' action, even if the user enters lower-case 'a' into the field. Regardless of what is entered as the answer in this text field, I simply cannot get a correct answer. Meanwhile, if the advanced action is changed to accept the upper-case 'A' as the correct answer, it works.
What am I doing wrong here? What do I need to do to make use of the combo box (or drop-box) widgets in the first place? Anyone with more experience?

Thanks for the response. it's Captivate 5 (sorry for forgetting).
I went ahead and renamed my variables to something more meaningful. That didn't quite resolve the problem. I went ahead with further investigation. I put five comboboxes, each with six different values and each populating their own variables. To see what's actually being entered into those variables, I put a simple text box on the side and populated it with variable values. My advanced action looked at those variables and and executed one of the two specific actions, depending on what the variables contained ("IF [variables] EQUAL TO [a set of data], then do this; ELSE do that"). However, no matter what they contained, it continued to execute the 'Fail' action, rather than 'Correct'. After a while, I noticed in that textbox that showed variable content, that there was a small space before the text. The space did NOT appear if I chose the first option on the list. This led me to see if the combobox would work if I listed options without any spaces. My original entry was: First, Second, Third, Fourth, Fifth. I changed the entry to: First,Second,Third,Fourth,Fifth. This finally solved my problem!
It seems that the widgets that come with Captivate don't behave consistently. Checkbox widget works properly when options are entered with spaces after commas. Combobox doesn't seem to. I haven't tested dropbox yet (I'm in a rush to deliver), but my guess is it won't allow spaces either.
One way to resolve this would have probably been to modify the action to say: IF [variable] CONTAINS [literal]..., instead of: IF [variable] IS EQUAL TO [literal]...
So, this problem has now been resolved. However, I now have a weird problem that I can't figure out, and it looks like a Captivate 5 bug. I have some 15 advanced actions. For some reason, I can no longer select one of them (no. 7 or so). All others I can select and edit, but this particular one I can't recall at all. The action no longer works correctly, so I re-created it, called it something else, and am now calling this new one. The original one can't be edited or deleted, and I'm just a bit concerned what's happened with that script.
Has anyone encountered this situation before?

[WPF] Editing Template and ComboBox

Hi,
sorry for my more questions about this problem, but I not understand how it works!
This is my code:
<DataGridTemplateColumn Header="{StaticResource datagridScheduled}" SortMemberPath="Type.Description">
<DataGridTemplateColumn.CellTemplate >
<DataTemplate>
<TextBlock Name="dgScheduleType" Text="{Binding Type.Description, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<ComboBox Name="dgCmbTypeOfSchedule"
ItemsSource="{Binding Source={StaticResource DomainDataViewModel}, Path=SchedTypes}"
SelectedItem="{Binding Type}"
IsSynchronizedWithCurrentItem="False"
DisplayMemberPath="Description"
SelectedValuePath="Value">
</ComboBox>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
Where:
1) Type is a Object of my collection with two property: Value and Description;
2) SchedTypes is a Object with two property: Value and Description
The value of TextBlock is shown correctly, but when I select an item of ComboBox it not shown on TextBlock!
Why? :(

Hi Robertino,
Instead of using databinding for your "TextBlock.Text" property, I would suggest you to use "Element Binding" over there.
This is because you already are binding your Type property to your combobox so instead of using the same property binding to your textblock.text use element binding of combobox.text with your textblock.text.
Please see below for your reference.
Change your textblock mark up to something like this.
<TextBlock Name="dgScheduleType" Text="{Binding ElementName=dgCmbTypeOfSchedule, Path=Text, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
This should resolve your problem.
Hope this helps!
Please mark it as an answer if the problem is resolved.

Goto Edit Dialog and ComboBox

I'm trying to make a very flexible and dynamic error handling routine. My goal is to be able to pop up a dialog when an error appears that has basically the same appearance and functionality as the Got Edit dialog which would allow me to go to any step in my sequence if an error occurred. I’m doing this in C#.
So far I am having some success but it really is a pain. I wanted to try to use what is already available but that is an even a bigger pain. i.e. after digging a little I located the CommonSubsteps.dll and all the code for the Goto Edit dialog etc… in
C:\Program Files\National Instruments\TestStand4.0\Components\NI\StepTypes\CommonSubsteps
First I tried to directly call the C++ dll functions from my Error Handling sequence but that bombed. Then I tried to make a C# wrapper class that just uses Interop wrappers around all the native C++ functions. Then I tried to actually make a managed C++ version of the CommonSubsteps.dll. I really can’t get any of these ways to work.
I have managed to make my own ComboBox and grab all the Sequence info from SequenceContext I pass it but there’s a lot of work to do with all the Icons etc…that’s why I started to try to use what was already there.
Anyone tried to do something like this already or have any advice as to how to go about using the native C++ stuff that is already there?

Hi,
Have you considered applying the SequenceView control along with the SequenceFileView Manager? By using this, you will have all of the icons and you should be able to get references to the different steps using the available properties.
Here is the API reference for the SequenceView control:
http://zone.ni.com/reference/en-XX/help/370052F-01/tsuiref/sequenceview/
I think this should get you started in the right direction but please let me know if you have any further questions.

ColorPicker and ComboBox library conflict

I need to use both components in an AS3 project, where components are created dynamically via script, but as I understand I need to put the components into the library anyway. First I add ColorPicker, then when I add ComboBox, I get a library conflict.
If I choose to replace items, and comlipe the project the ComboBox works but ColorPicker starts producing errors, if I choose to use the existing items, the ComboBox produces errors when I click on it.
Does anyone know how to make them work together?
RESOLVED: The conflict was caused by a library movieClip that didn't belong to ColorPicker or ComboBox movieClips but had a matching name

Well I was informed on another forum that I can not jar other jar files in my jar file (this sentence had to much 'jar' in it!). Or at least the class loader will not go search for the required libraries there.
(the other forum is about ANT, so I did not cross post the same question ;)
Basically I am working on a web application that can convert data into PDF using the Apache FOP library. Now I require to add the functionality to convert the data into RTF as well. The new beta version of Apache FOP can do this, but for some weird reason when deployed on JBoss it is not converting my data to PDF. (the current Apache FOP version is still in beta 0.92beta).
Now therefore I decided to provide a temporary solution. That is use the old library when I need a PDF file, and use the new library when I need to RTF file. Then when a more stable FOP comes out I try to combine the two.
(additional information on FOP: FOP has passed from a complete transformation from the last version to this one, therefore at a certain stage I will drop the old code and start working on the new one).
Basically that is my problem in detail. I am trying to come out with solutions, and I do not want to believe it is a deadlock!

Actionscript 3 XML, Data Providers, and ComboBox

So i'm trying to use my imported XML, that I turned into an
XMLList as a DataProvider for a Combo Box.
Must you turn an XMLList into an array to accomplish this?
This code traces my list as an array, which seems ready to be
set as a DataProvider. I've tried setting the DataProvider to the
Array, to the function that creates the Array and also directly to
the XMLList, but so far no luck.
What am i doing wrong?

try:
import fl.events.ListEvent;
var leadloader:URLLoader = new URLLoader();
leadloader.addEventListener(Event.COMPLETE, onLoaded);
leadlist.addEventListener(ListEvent.ITEM_CLICK, openMailClient);
function openMailClient(e:ListEvent):void {
   var request:URLRequest=new URLRequest("mailto:"+leadlist.getItemAt(int(e.rowIndex)).data);
    navigateToURL(request,"_self");
var xml:XML;
function onLoaded(l:Event):void {
    xml = new XML(l.target.data);
    var offlst:XMLList = xml.office;
    for (var i:uint=0; i<offlst.length(); i++) {
       leadlist.addItem({data:offlst.emllink.text()[i],
               label:offlst.officenm.text()[i]});
leadloader.load(new URLRequest("officeleads.xml"));
