Combobox selection
Hi
I have a combo which is populated with some items. When I drop down and keep scrolling and, on my mouse movement over the listed items I should get a tool tip text and not when an item is selected.
My getSelectedItem works fine only when a selection is made with the click of the mouse and my setToolTipText is working fine after the getSelectedItem(), which is not all I want !
All I want is... Tool tip should be displayed before a selection is made by the click of mouse, i.e. when a drop down is made !!
Kindly help me out before I pluck every hair of mine
Thanx in advance

In Handeling Events on a ComboBox in
http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html
It is recommended that we do not listen for low-level events like MouseEvents on ComboBoxes which are compound components. Low-level events are look-and-feel dependent.
See Concepts: Low-Level Events and Semantic Events in
http://java.sun.com/docs/books/tutorial/uiswing/events/generalrules.html

Runtime loading of XML file off a ComboBox selection
I need to load an XML file at runtime based on a ComboBox
selection that has the XML file path as its data.
I figured out how to load an XML file at runtime by defining
an HTTPService
<mx:HTTPService id="stocksXML" url="xml/StockList.xml"
resultFormat="e4x"/>
and setting the <mx:Application
creationComplete="stocksXML.send();"
But when I now try to set the HTTPService url dynamically in
the ComboBox change event handler
private function loadData_changeHandler(event:ListEvent):void
stocksXML.url = event.target.selectedItem.path;
stocksXML.send();
no data gets retrieved and the stocksXML.lastResult is null.
What am I missing here? Why doesn't that work?
Thanks in advance for any pointersI suggest adding a resultHandler to the HTTPService and check
the results there. Also add a faultHandler so that you will know
what the error was. -
Change Data Provider Based on ComboBox Selection
Complete noob using Flash CS5 for Macs. I have a ComboBox component and a TileList. I want the ComboBox selection to change the data provider for the TileList. I've used a sample script from the Adobe website at the bottom, but it is not working in this context. Google returns no better examples. Can anyone point me in the right direction?
import fl.controls.ComboBox;
import fl.data.DataProvider;
import flash.display.DisplayObject;
import flash.display.MovieClip;
import fl.events.DataChangeEvent;
// Combo Box ("aCb")
var aCb:ComboBox = aCb;
var Choices:Array = new Array(
{label:"Artist Resin", data: "resin"},
{label:"Ceramic", data: "ceramic"}
aCb.dataProvider = new DataProvider(Choices);
// TileList ("aTl")
aTl.columnWidth = 110;
aTl.rowHeight = 130;
aTl.setSize(110,150);
aTl.move(20, 150);
aTl.setStyle("contentPadding", 5);
// TileList Content
var i:uint = 0;
var resinitems:Array = [
{label: "Image 1", source: "http://www.helpexamples.com/images/montreal/images/IMG_5057.jpg"},
{label: "Image 2", source: "http://www.helpexamples.com/flash/images/gallery2/images/IMG_1592.jpg"}];
var resin:DataProvider = new DataProvider();
for(i=0; i < resinitems.length; i++) {}
var ceramicitems:Array = [

{label: "Image 4", source: "http://www.helpexamples.com/flash/images/gallery1/images/pic14.jpg"},];
var ceramic:DataProvider = new DataProvider();
for(i=0; i < ceramicitems.length; i++) {}
addChild(aCb);
addChild(aTl);
// Code to Change Data Provider for Tile List
aCb.addEventListener(Event.CHANGE, changedataProvider);
function changedataProvider(event:Event):void {
aTl.dataProvider = event.target.selectedItem.data;Thanks for your answers.
I have already checked those links.
Now th problem what I am facing is,
I am not able to call the function ChangeLanguage through javascript.
I have created a dropdwon using Hovermenu and added English and German.
Now when I click on these the function should be called.
Please help me in getting how setClientSideScript() can be used to call a function.
or any other way to call the function after clicking on Hovermenu Item.
Thanks in advance,

How set margin/padding top to combobox selected value
Hi,
Again I am facing new problem with combobox component, i need to set margin/padding top to combobox selected data using external AS file.
I have tried the code --> combo_box.setStyle("marginTop", 5); and also used similar styles but its not working.
Need your suggestions and help.
Thanks.Hi,
i strongly urge you to read some book about CSS and forget using deprecated HTML tags like FONT.
Why am i saying that?
Well, you don't want to change a page template or a report definition every time the user complains about the size of a font or the space between lines, do you?
CSS is all about presenting the page the way you want, setting margins, spaces, fonts and so on.
You should focus on the content, the data, leaving the task of formatting to one or more CSS stylesheet linked in the HTML header.
I recommend reading some articles first, at least to have a general idea of mainstream techniques:
http://www.alistapart.com/articles/goingtoprint/
http://webdesign.about.com/cs/css/a/aa042103a.htm
Or you can google around searching for "css formatting printer friendly" to get a bunch of pages.

Changing variable with combobox selection - simple problem!
Hi there,
I have a search field when you click on search.
I want to make it so i can change which field in a datagrid
you search for depending on the choice in the Combbox. I'm not sure
how to set the object name correctly depending on the combobox
selection.
I tried it like this, to no avail
private var acOrder:ArrayCollection
private var currentOrder:Object;
///////////////this is incorrect. What should i use instead
of Object?//////
private var whichArray:Object
private function makeid():void
whichArray = "orderid"
private function makeemail():void
whichArray = "email"
private function filterByOrderid(item:Object):Boolean
if (item.(whichArray) == filterTxt.text)
////I want this result to either be if (item.orderid ==
filterTxt.text)
///or if (item.orderid == filterTxt.email)
return true;
else
return false;
private function doFilter():void
if (filterTxt.text.length == 0)
acOrder.filterFunction = null
else
acOrder.filterFunction = filterByOrderid;
acOrder.refresh()
i think answer is very simple. i just need to pass the name
of the item inside the object correctly
thanks very much for any helpHi,
Try declaring whichArray as String and try this
item[whichArray] instead of item.(whichArray).
Hope this helps. -
Combobox Selection Takes Action
I am trying to learn how to use a combobox selection (two items in the list) to take and action such as changing the color of boxes I have acting as a border around my form or, better yet, possibly to hide or view a button. I am asking for help in devleoping a generic code into which I can insert the names of my fields I wish to hide or view. Can anyone help? I know NOTHING about Javascript. Thanks in advance.
Richard PThe code below should work. Each OPTION in each case is the name of your drop downs for the combobox. You place the code in format under custom keystroke. Everytime you choose one of the dropdowns it will run whatver code you placed for the case. this.getField("YOURFIELDNAME").display = display.hidden should work for hiding, replace hidden with visible and voila.

Iam creating the combo boxes as follows from another source file.
private AutoSearchComboBox indexTagCombo,indexValueCombo
//The following function is called for loading the comboBoxes.
private void loadInitialIndexTagValues()
indexTagCombo.removeAllItems();
//Getting values to be fiiled in the comboBox.
Set tags = this.model.getAvailableIndexTags();
// Iterating over the elements in the set
Iterator tagIter = tags.iterator();
while (tagIter.hasNext()) {
indexTagCombo.addItem(tagIter.next());
//Loading index values.
String currTag = (String)indexTagCombo.getSelectedItem(); //Selection problem 1
The statement above returns me null & the follwing code doesnt fill the other comboBox.
Set values = model.getAllValues(currTag);
indexValueCombo.removeAllItems();
Iterator valIter = values.iterator();
while (valIter.hasNext()) {
indexValueCombo.addItem(valIter.next());
Have added an "itemListener" to the indexTagCombo as follows:
indexTagCombo.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent e)
indexTagSelection(e);
private void indexTagSelection(ItemEvent e) {
if (e.getStateChange() == ItemEvent.SELECTED)
//The "getStateChange" is never ItemEvent.SELECTED,so that it never gets in to this loop.//Another problem
//code goes Here
There is some problem with the defined "AutoSearchComboBox" with selection.When I change the privately defined "AutoSearchComboBox" to JComboBox and make it editable,all the selection problems are gone.
In short all the "getSelectedItem" from the "AutoSearchComboBox" and the "itemstate" events defined are not going to the "ItemEvent.SELECTED"
What should I fix in the "AutoSearchComboBox" so that the selections work.
Any help is greatly appreciated.
Thanks
PHi Smita,
When you create the Transaction code either thru Se80 or thru Se93... please see that you are giving the screen number asked there as 1000, which is the default screen number for the selection screen.
Also, please see if the checkboxes for the GUI Support are ticked. I think it iwll solve you problem.

Set PHTML ComboBox Selected Value in JavaScript?
I've created a combobox as follows:
<phtmlb:comboBox id = "sdm_cnis"
selection = "<%= L_CIP_DETAILS_WA-GBSCIND %>"
table = "<%= l_cnis %>"
readOnly = "<%= l_display_mode %>"
width = "50px"
nameOfKeyColumn = "VALUE"
nameOfValueColumn = "NAME"
onClientSelect = "javascript:sdm_toggle_required();return false;"
behavior = "DROPDOWNSELECT" />
Based on the selected value of another dropdown combobox, I want to use JavaScript to select the value of this comboBox. For example, if the user changes the first comboBox, I want to automatically select the first option in this combobox. I really do not want to use dropdownListBoxes because they are not used anywhere else in our application. I also do not want to make a round trip to the server in order to resolve this issue as our uses will complain too much about that.
Some other things I've learned/tried:
I know I can get the selected value as follows:
sapUrMapi_ComboBox_getSelectedKey('sdm_cnis');
I have also tried to do the following, which sort of sets the value, but when you pull the list it appears as though the old selected value is still selected:
window.document.getElementById('sdm_cnisKEY').value = cnis_key;
window.document.getElementById('sdm_cnis').value = cnis_value;
Any help is appreciated.
RickManaged to come up with a solution:
window.document.getElementById('sdm_cnisKEY').value = cnis_key;
window.document.getElementById('sdm_cnis').value = cnis_value;
var o=sapUrMapi_ComboBox_getObject("sdm_cnis");
o.txt.setAttribute("k",cnis_key);
o.txt.setAttribute("ks",cnis_key);
I'm not sure, but I would imagine that this solution is not supported by SAP and any patches or service pack upgrades could potentially break the code, so if you use it, be cautioned about this.
I have tested it on our server, and it works for my current scenario. That said, if there is a better way to do this in JavaScript, I'd love to hear it. For now, I'll leave the question open and assign full points if someone can come up with something that I feel is better than this (i.e. a JavaScript solution that is supported by SAP).

2007A - Problem with Combobox.Selected with an empty value
Hi all,
I 've tried to launch my add-on created with SBO 2005 SP1
on 2007 client.
I've a problem when I try to do
myCombobox.Selected.Value
when the valid value is empty.
Selected is null and I've an error.
So I must test each Combobox by doing this :
if( myCombobox.Selected is null)
But I've hundreds of this case in my code.
Does an another solution exists?
Thanksyou have the same problem in every business one version.
you first have to check if the property is not null/nothing
the only other way is that you use try / catch
value = oform.Items.Item("cmb1").Specific.selected.value()
Catch ex As Exception
value = ""
End Try
but the effort is the same for you -
Losing comboBox selection in JTable
I have a JTable where one column consists of comboBoxes. It is possible to add and remove rows from this table using the associated buttons.
Unfortunately if I have made a choice from a comboBox, yet not selected another cell in the table, then I use the 'add' button to add a new row, I lose the selection just made in the comboBox.
If I first select another cell in the table this is not a problem and it works fine.
Any help much appreciated....thanks for that, but I'm afraid it was no help.
I'm using Java 1.1.7 and the getCellEditor(int, int) method doesn't exist. doing the same with getCellEditor() doesn't produce the required results.
The comboBoxModel is updated when a new selection is made, but the cellEditor isn't updated until you click on another location in the table. Unfortunately I don't know how it goes about doing this, so I can't imitate it in my 'add' method -
I have an application that populates combobox2 based off of the selection made in combobox1. When a selection in combobox1 is made, I call a function that connects to a database and gets a list of all compatible parts for the selection in combobox1 from the MySQL table. I read the result set into a vector. I then pass the vector to combobox2 and it displays the list. Everything works perfectly.
The columns in MySQL are: sku, manufacturer, speed, cores, fsb, cache, l1,l2, compatible. I am puling out everything but the sku and compatible, and adding them to each row of the vector.
The problem I have is that after the user picks the option they want and it is time to submit the form, I want to get the sku number associated with their selection. Unfortunately, I can't go back to the database, as the manufacturer, speed, cores, fsb, cache, l1 and l2 might match hundreds of records. (I am using the column called "compatible" to determine which records go with which combobox1 selections).
What I can not seem to grasp, is what data structure I need to use to store the sku and the manufacturer/speed/cores/fsb/cache/l1/l2 so that they can be related to one another inside the combobox. I don't want to display the sku to the user, as that is unnecessary information.
There is a way in VB.net to set a value for a selection in the combobox, so that what is selected and what is sent to the system can be different. I don't know if something like that exists in Java. I don't know if something like an ArrayList would be better.I may have just answered my own question. I can still go back to the database and pull the sku based on description, I just have to remember to include a check against the compatible list.(There should never been two rows with the exact same description for the exact same system.) However, that will require me to break out my string. See, when I read the a row into the vector I do:
optionsVector.add(rs.getstring("manufacturer" + "speed" + "cores" + "fsb" + "cache" + "l1" + "l2");
So in reverse I would have to break out the line "Intel, 2.5ghz, 4 cores, 800mhz, 8mb, 512k, 512k" into the original format and then search. Should be easier with the commas as delimiters. Still, seems like there should be an easier way. -
Dear all,
I'm newbie of javafx and I'm working on my first application.
I found several issues, for now it doesnt' seems to me a very productive environment, due to lack of components and documentation.
Now I stopped on a very basical question, but I can't go on.
Iìve a combobox and I want to implement selection changed logic, that is basing on selected value some logic must be run.
I didn't find any event like selection changed.
Can you help me with some code or links?
Thanks,
RegardsI guess you actually want to use a ChoiceBox (there is no ComboBox class in JavaFX :p).
The best way I have in mind is binding the ChoiceBox.selectedItem to a variable and set an onreplace trigger on it. Like that:
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.control.ChoiceBox;
var choiceBox: ChoiceBox;
var currentItem = bind choiceBox.selectedItem on replace{
println("{currentItem} selected!");
Stage {
title: "MyApp"
scene: Scene {
width: 200
height: 100
content: [
choiceBox = ChoiceBox {
items: ["Item1","Item2","Item3", "Item4"]

Help with ComboBox Selection Update
Hello,
I am trying to make this application display all its labels in a different language depending on which locale the user picks from the ComboBox. The variables are being read from the ResourceBundles correctly (see command-line debugging statements) but I cannot get the pane to 'refresh' when the item is selected. I've tried everything I can think of! Please help! :)
(This assignment was to internationalize a program we wrote for a previous assignment, so this program wasn't originally written to do this. I am trying to add this functionality to my existing project, so it's not ideal).
Thank you for any advice, help or hints you can give!

From the Communiy Rules in the Welcome section....
Objectives of Lenovo Discussion Forums
These communities have been created to provide a high quality atmosphere in which users of Lenovo products and services may share experiences and expertise. While members from Lenovo may participate at intervals to engage in the discussions and offer advice and suggestions, this forum is not designed as a dedicated and staffed support channel. This is an informal and public forum, and Lenovo does not guarantee the accuracy of information and advice posted here -- see important Warranty information below.
No amount of ranting is going to get you anything more than you will achieve with a clear exposition of your issue... so you might want to try doing that instead of ranting and assuming that everyone already knows what you know etc etc.

Binding textbox to combobox selected value when the selected value is blank
I have a simple form that binds data to a combobox and when one of the values in the combobox is selected it fills a textbox with the corresponding column in that table. However, if that combobox value is empty(meaning that table cell is empty) then
the textbox will not fill with the correct value. I am finding this hard to explain so I will lay it out.
The table[COA] is as follows:
ID
Fund
Fund Description
Bus Unit
Bus Unit Description
Obj
Obj Description
Sub
PEC
1
2789
Account Refund
10000
General Fund
1500
ASC Voucher
10
2
2789
Account Refund
10000
General Fund
1500
Voucher
The following is my code:
private void subComboBox_SelectedIndexChanged(object sender, EventArgs e)
pECTextBox.Clear();
using (SqlConnection connection = new SqlConnection(@"Data Source=MARYANNEBORJA\SQLEXPRESS;Initial Catalog=jdeDatabase;Persist Security Info=True;User ID=Jordan;Password=*****"))
SqlCommand command = new SqlCommand("SELECT * FROM [COA] WHERE [Bus Unit]='" + bus_UnitComboBox.Text + "' AND [Obj] ='" + objComboBox.Text + "'AND [Sub] ='" + subComboBox.Text + "'");
command.Connection = connection;
connection.Open();
SqlDataReader read = command.ExecuteReader();
while (read.Read())
if (!read.IsDBNull(8))
pECTextBox.Text = (read["PEC"].ToString());
else
pECTextBox.Text = "";
obj_DescriptionTextBox.Text = (read["Obj Description"].ToString());
read.Close();
I fill my combobox with Sub values based on the Bus Unit and Obj. Since the Bus Unit and the Obj in both rows are the same the combobox is filled with 10 and "".
Here is where the problem occurs. When I select "10" in the combobox I want a textbox to fill with correct Obj Description field. So selecting "10" would give me 'ASC Voucher' in the textbox and selecting "" should
give me 'Voucher' in the textbox, but this is not the case. I can only get 'ASC Voucher' to fill the textbox. When I select "" it keeps the textbox at 'ASC Voucher'.
My guess us that is has something to do with the value being empty in that table cell because when I am selecting other values it works.
Any guess as to what I should do?Hi objectifyThat,
When Your subComboBox.Text is null, you should use "Sub is null" in your SQL like below.
private void comboBox3_SelectedIndexChanged(object sender, EventArgs e)
pECTextBox.Clear();
using (SqlConnection connection = new SqlConnection(@"Data Source=MARYANNEBORJA\SQLEXPRESS;Initial Catalog=jdeDatabase;Persist Security Info=True;User ID=Jordan;Password=*****"))
string cmdstring = "SELECT * FROM [COA] WHERE [Bus Unit]='" + bus_UnitComboBox.Text + "' AND [Obj] ='" + objComboBox.Text + "'AND [Sub] ='" + subComboBox.Text + "'";
if (string.IsNullOrEmpty(subComboBox.Text))
cmdstring = "SELECT * FROM [COA] WHERE [Bus Unit]='" + bus_UnitComboBox.Text + "' AND [Obj] ='" + objComboBox.Text + "'AND [Sub] Is Null";
SqlCommand command = new SqlCommand(cmdstring);
command.Connection = connection;
connection.Open();
SqlDataReader read = command.ExecuteReader();
while (read.Read())
if (!read.IsDBNull(8))
pECTextBox.Text = (read["PEC"].ToString());
else
pECTextBox.Text = "";
obj_DescriptionTextBox.Text = (read["Obj Description"].ToString());
read.Close();
If you have any other concern regarding this issue, please feel free to let me know.
