Flex :: Setting A Custom ItemRenderer In A ComboBox On Specific List Items After Combobox Creation?
Nov 8, 2010
I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.
I have a combobox and list component on the stage. The combobox has 3 selections. How do I get it so that each selection triggers the specific xml file to load into the list component? I can't get them to communicate to each other.
I'm using Flash CS3 and want to create a custom ComboBox. I've followed the steps outlined in "Editing component skins in a new document" (http:/[url]...), but every time I get to the step where I drag the ComboBox Assets folder from the HaloTheme.fla library into my library, if I test movie at that point my combobox has become an unclickable white rectangle with no label, button or anything.
I am trying to create a combobox where the items listed in the combobox are font names and each item will display using the font of the item label. For instance, one item label in the list is "New Times Roman" and I want that particular row in the combobox to have the text AND font of "New Times Roman". For some reason, inside of my custom CellRenderer class, I cannot seem to find a way to get the item label that corresponds to the CellRenderer and the CellRenderer.data item always appears to be null!
This is the code I am currently using:
//From the main class, I am creating an instance of the CustomizableComboBox and adding in the font names I am interested in. var comboFont:CustomizableComboBox=new
I have a flex combobox as a datagrid itemEditor. However, after selecting an item in the combobox, its necessary to click out of the combo (i.e. into another cell or elsewhere in the app) for the value to be committed to the combo. Prior to this, the combo sits 'proud' of the datagrid and the value hasnt actually been committed.
Is there a way to force the value to be immediately committed after an item has been selected and for the combo to 'lose focus'?
I need to create a Flex component similar to ComboCheck (by Arcadio Carballares).What I need is a ComboBox with CheckBox and TextInput instead of Checkbox's label.If CheckBox is selected the TextInput is enabled and editable, other way it's disabled.
I have a data grid with an Combobox itemRenderer in it. What I have is a grid with a person id and person name (more stuff in grid but I am struggling with this). In the person name column I have an combobox with all the people on then system's names and id's. What I want to do is when I select a person in the combobox I want the combobox to populate the person name fields (which it does) but I also want to pull out the person id from the combobox and populate the person id column in the data grid as well.
The renderer shows html text properly in the drop down list, but in the top most option (selected item) the whole HTML tag is shown instead of what the tag represents.
I have a Flex list and a custom ItemRenderer. I'd like to be able to have some items in the list use a different ItemRenderer (say, depending on the class of the item). Is this possible?
i am using an itemRenderer in mx:list, it has many text fields and combos, i use this item renderer to edit items in array collection, each item in the arrayCollection is of type Action which comes from BlazeDS remoting as a valueObject.my problem is when i add new item of type Action to the list dataProvider (ArrayCollection) by this code
myList.dataProvider.addItem(new Action());
the new item tooks the same data from its previous item.
I have a combobox that uses a custom itemrenderer to display an image. when scrolling up and down the list the images randomly go out of alignment. How do I stop this?
public class PinRenderer extends UIComponent implements IDataRenderer, IListItemRenderer { private var currentPin:DisplayObject; private var _data:Object; public function get data():Object { return _data; } public function set data( value:Object ):void { [Code] .....

I need to programmatically set the selected item in a combobox. I've got a combobox like this: <mx:ComboBox id="MyComboBox" change="puzzleHandler(event);"prompt="Make a Selection"> <mx:ArrayCollection id="myDP"> <mx:Object id="first" label="Label 1" series="2" pageTitle="Title 1"/> <mx:Object id="second" label="Label 2" series="7" pageTitle="Title 2"/> <mx:Object id="third" label="Label 3" series="9" pageTitle="Title 3"/> </mx:ArrayCollection></mx:ComboBox>
I've got a function that regards deep linking. [URL]. They'll be taken to the appropriate part of the site (without having selected Label 2 in the comboBox). How do I set the comboBox programatically, so that it corresponds with what the user it looking at? In my function's switch statement, I want to set the comboBox to the label that corresponds with the view. If "view=2" then the comboBox should show "Label 2" as selected.
case "view=1": MyComboBox.selectedItem.label="Label 1"; parseUrl(); case "view=2": [Code] ..... I tried this: MyComboBox.selectedItem.label="Label 1" But it's not working.
I need a custom Combobox in flex(as an ActionScript file), where I need to display in dropdown all the data nodes in the dataprovider as comma seperated values and when selecting only display one single node/value in textInput. How can we implemented this.
I've wrote a custom itemrenderer for a List component (Flex 3.5) which is a VBox with a Label and a TextArea wrapped inside. All works fine so far but I want the TextArea in the first itemrenderer to receive focus so that it instantly becomes editable when tabbing onto the List. Is that possible and if how would I achieve this?
I've already added an event listener that selects the item at index 0 but the textArea in it should also be focussed at that moment _list.addEventListener(FocusEvent.FOCUS_IN, onListFocusIn);
private function onListFocusIn(e:FocusEvent):void { _list.selectedIndex = 0; }
I am using the combocheck example from the following site: [URL]
It's a very useful component and works very well.
Now, I need to set the text property of this combo box upon application startup with certain values (which are defined dynamically according to some criteria). The problem is that although I have no problem setting the text property of the combo box at other times of the application run, setting the property at startup seems to have no effect unfortunately.
For example, I want to set the text property of the combobox to "Bob" (which is one of the items in the dataprovider for the combobox) and the "set text" method is called on the combo box. Performing a step-through shows that the "set text" method is receiving the correct value item but not setting the _text property.
I have tried not doing anything until "ApplicationComplete" but no joy there either.
Here is the code (a combination of the code from the URL above and some other changes to it). However, as I've stated above, the codes does work. The problem is that it doesn't work at the application startup. Whenever an event is fired and setComboText is called as a result, the text of the combo box is set correctly.
private function onComboChecked(event:ComboCheckEvent):void { var obj:Object=event.obj; var index:int=selectedItems.getItemIndex(obj);
But the ComboBoxes are being created dynamically with AS3, everything is working except I cant bind the second ComboBox dataProvider to be the XMLList in the first ComboBox's selectedItem.
Trying to set the up and down state icons of a Flex Combobox to images. I see the property for changing the color of the icon, but no property to skin it. How can I do this?
When a combobox is elected in the flex app, there is a quick flicker, then the combobox needs to be selected again in order to get the dropdown to open. After that, the dropdown works as expected, but only while selecting the control subsequent times while on the form. Reloading the form requires the double selection again.
im having some dificulties in the combobox of Flex 3, after defining the dataProvider and filling the combobox, how can i remove the items in the combobox later (without removing items in the dataprovider)? if i set the provider to "" or null, the items in the combobox are still there
I'm using a custom itemrenderer to display a list of photos and need to know how to control the width. At the moment it does this: Which, as I'm sure you'll agree, is eye-bleedingly ugly. The list is created like this:
I am using a List with an ArrayCollection as a DataProvider. The list uses ComboBox as Item Renderer itemRenderer="mx.controls.CheckBox"I would like to bind the values in the List.You have a list with several comboboxes, and those values are loaded dynamically from an ArrayCollection.The ArrayCollection contains Objects with a boolean property for which I should bind the True/False values selected in the comboboxes.

**Warning** The linkage identifier 'ComboBox' was already assigned to the symbol 'ComboBox', and cannot be assigned to the symbol 'GUI MC/Combo Boxes/abc', since linkage identifiers must be unique.**Warning** The linkage identifier 'ComboBox' was already assigned to the symbol 'ComboBox', and cannot be assigned to the symbol 'GUI MC/Combo Boxes/def', since linkage identifiers must be unique.
Both of my ComboBoxes has the same identifier.I could not change the identifier through the properties tab because it is greyed out.
