How to populate struts2 combo with string array - combobox

statesList is ArrayList that contains String object.
String[] states = new String[2];
states[0] = "CA";
states[1] = "California";
statesList.add(states);
//---
<s:select list="statesList" headerKey="" headerValue="Select State" name="state" listKey="?" listValue="?" />
What to mention in listKey and listValue??

Your statesList is ArrayList that contains String[] object, instead of String.
With this said you can change your code to:
Map<String,String> statesList= new HashMap()<String,String>;
statesList.put("CA","California");
<s:select list="statesList" headerKey="" headerValue="Select State" name="state" listKey="key" listValue="value" />

.NET WPF set combobox selected item

I am setting items in a combobox with this:
Dictionary<int, string> myItems = await resp.Content.ReadAsAsync<Dictionary<int, string>>();
myCmb.Items.Clear();
myCmb.ItemsSource = myItems;
myCmb.SelectedValuePath = "Key";
myCmb.DisplayMemberPath = "Value";
Then I want to select item by Key (for example, select item with Key=5) in another part of the code. How can this be done?
myCmb.SelectedItem = myItems.FirstOrDefault(n => n.Key == desiredKey);
You can do it this way but you will need to have myItems accessible from the another part of code.

How to retrieve field from custom master object?

I am trying to write a custom object and have to retrieve one custom related field from custom object Course Master(master) to detail object Training deals. This code is showing error
List<List<String>> strList = new List<List<String>>();

AS3 Separating Arrays for different items

I have a function that creates a new value inside an associative array.
var array:Array = new Array(new Array());
var i : int = 0;
function personVelgLand(evt:MouseEvent)
{
for(i = 0; i < personListe.dataProvider.length; i++)
{
if(txtPersonVelg.text == personListe.dataProvider.getItemAt(i).label)
{
personListe.dataProvider.getItemAt(i).reise = array;
personListe.dataProvider.getItemAt(i).reise.push(landListe.selectedItem.land);
}
}
}
What happens is that the 'array' array which becomes 'personListe.dataProvider.getItemAt(i).reise' applies to every item in the list. I want it so that each time the function runs that the .reise only applies to the item chosen and not all of them.
EDIT:
I did this:
personListe.dataProvider.getItemAt(i).reise = new Array(array);
And now they are not the same but now each item in the list can not have multiple .reise values...
EDIT 2: dataProvider is nothing it would work just as fine without it. .reise is created in the function I originally posted it creates .reise in the object getItemAt(i).
personListe is a list which the users add their own items to by the use of a input textfield. It is given by this function:
function regPerson(evt:MouseEvent)
{
regPersoner.push(txtRegPerson.text);
personListe.addItem({label:regPersoner});
regPersoner = new Array();
txtRegPerson.text = "";
}
EDIT 3 : The user can register names which turn in to labels in a list. There is also list with 3 countries, Spain, Portugal and England. The user can then register a country to a person they select. Thats when I want to create the .reise inside the "name" items in the first list which contains the countries they have selected. I want every name to be able to select multiple countries which then will be created in the element .reise inside the item that holds their name. This would be easy if I could use strings. But later I plan to have the user type in a country and then something that would show every user that have selected that country. That is why the countries need to be stored as arrays inside the "name" items..
You should first create a class for the User data that you are modelling. You already know all the properties.
The user can register names
The user can then register a country to a person they select.
able to select multiple countries
Such a class could look like this:
package
{
public class User
{
private var _name:String;
private var _countries:Array;
public function User(name:String)
{
_name = name;
_countries = [];
}
public function get name():String
{
return _name;
}
public function get countries():Array
{
return _countries;
}
public function set countries(value:Array):void
{
_countries = value;
}
}
}
Now create a DataProvider, fill it with objects of that class and use it for the list as described here:
import fl.controls.List;
import fl.data.DataProvider;
var users:List = new List();
users.dataProvider = new DataProvider([
new User("David"),
new User("Colleen"),
new User("Sharon"),
new User("Ronnie"),
new User("James")]);
addChild(users);
users.move(150, 150);
In order to get a label from a User object, define a labelFunction
import fl.controls.List;
import fl.data.DataProvider;
var users:List = new List();
users.labelFunction = userLabelFunction;
function userLabelFunction(item:Object):String
{
return item.name;
}
users.dataProvider = new DataProvider([
new User("David"),
new User("Colleen"),
new User("Sharon"),
new User("Ronnie"),
new User("James")]);
addChild(users);
users.move(150,150);
This way you do not have to add a label property that you don't want in your class.
Selecting a name means selecting a user. The list of countries associated to the name should show up in a second List.
The DataProvider of that List remains constant, a list of all the available countries.
import fl.controls.List;
import fl.data.DataProvider;
// list of users
var users:List = new List();
addChild(users);
users.move(150,150);
users.labelFunction = userLabelFunction;
function userLabelFunction(item:Object):String
{
return item.name;
}
users.dataProvider = new DataProvider([
new User("David"),
new User("Colleen"),
new User("Sharon"),
new User("Ronnie"),
new User("James")]);
// lsit of countries
var countries:List = new List();
addChild(countries);
countries.move(550,150); // adjut position as desired
countries.dataProvider = new DataProvider([
{label:"a"},
{label:"b"},
{label:"c"},
{label:"d"},
{label:"e"},
{label:"f"}]);
Now all you have to do is to wire it all up. If a user is selected, select his countries in the countries list. If a country is selected, add that to the currently selected users list of countries. That could look somethign like this:
users.addEventLsitener(Event.CHANGE, onUserSelected);
function onUserSelected(e:Event):void
{
countries.selectedItems = users.selectedItem.countries;
}
countries.addEventLsitener(Event.CHANGE, onCountrySelected);
function onCountrySelected(e:Event):void
{
users.selectedItem.countries = countries.selectedItems;
}
The full code could look like this. I did not test this, but you get the idea.
// list of users
var users:List = new List();
addChild(users);
users.move(150,150);
users.labelFunction = userLabelFunction;
function userLabelFunction(item:Object):String
{
return item.name;
}
users.dataProvider = new DataProvider([
new User("David"),
new User("Colleen"),
new User("Sharon"),
new User("Ronnie"),
new User("James")]);
// list of countries
var countries:List = new List();
addChild(countries);
countries.move(550,150); // adjut position as desired
countries.dataProvider = new DataProvider([
{label:"a"},
{label:"b"},
{label:"c"},
{label:"d"},
{label:"e"},
{label:"f"}]);
// events
users.addEventLsitener(Event.CHANGE, onUserSelected);
function onUserSelected(e:Event):void
{
countries.selectedItems = users.selectedItem.countries;
}
countries.addEventLsitener(Event.CHANGE, onCountrySelected);
function onCountrySelected(e:Event):void
{
users.selectedItem.countries = countries.selectedItems;
}
From what I understand this seems to work except for the fact that the names are already provided when the program starts. What I want is that the user adds the name themselves while the program is running.
You can add new items with the methods provided by the DataProvider class, like addItem() for example. Just add new User objects.

Qooxdoo form elements and getSelection()

Here's my code:
var sb = new qx.ui.form.SelectBox();
sb.add( new qx.ui.form.ListItem("English") );
sb.add( new qx.ui.form.ListItem("Nederlands") );
sb.add( new qx.ui.form.ListItem("Deutsch") );
sb.add( new qx.ui.form.ListItem("français") );
sb.add( new qx.ui.form.ListItem("Српски") );
How do I use setSelection() to select "Deutsch", and what if the items are numeric values? Can I also set values for these labels or is SelectBox() limited to labels?
For example:
value: en, label: English
value: de, label: Deutsch
etc.
Take a look at the example code below.
You can specify a model with each ListItem for storing additional information. It can act as value property on form items for example. See http://demo.qooxdoo.org/1.0.x/apiviewer/#qx.ui.form.ListItem
var selectBox = new qx.ui.form.SelectBox();
selectBox.add( new qx.ui.form.ListItem("English", null, "en" ));
selectBox.add( new qx.ui.form.ListItem("Nederlands", null, "nl" ));
var defaultItem = new qx.ui.form.ListItem("Deutsch", null, "de" );
selectBox.add(defaultItem );
selectBox.add( new qx.ui.form.ListItem("français", null, "fr"));
selectBox.add( new qx.ui.form.ListItem("Српски", null, "ru"));
selectBox.setSelection([defaultItem]);
selectBox.addListener("changeSelection", function(e) {
//Read model data from listitem
this.debug("changeSelection: " + e.getData()[0].getModel());
});
Maybe this example will be useful for you too:
var sb = new qx.ui.form.SelectBox();
var a = ["English", "Nederlands", "Deutsch", "Français", "Српски"];
var model = new qx.data.Array(a);
var controller = new qx.data.controller.List(model, sb);
controller.setSelection(model.slice(0,3));
At last line model.slice(0,3) returns subarray of model with three elements: from "English" to "Deutsch". And last element in this subarray will be "selected" by default.
See "Data Binding" in qooxdoo's manual for details.
