Make An Item Editor In Flex List Component Commit It's Changes?
May 19, 2009
I have a list component and I have an item editor for the items in the list. I would like to have a button that the user clicks once they are done with their changes because I am having them edit multiple pieces of data in the editor and I would also like to validate the data before closing the editor as well. I just don't know what to do on the button's click event to make the item editor close and commit it's changes to the data provider.

I have a regular spark list which is sorted correctly when no item renderer is used. However, when the following item renderer is used, the list shuffles and displays items from previous instances of the list.[code]

I have found something good here. [URL]..The mouseover effect on the list item is good. Any ideas to make this look.. I can infer that this is happening on mouseover of the Image Component. I think this is similar to google image search preview of images. If anyone have come across a component similar to this kindly share it to me and to all.

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

Is it possible to make an item in a List control not selectable? If so, how would this be accomplished?
I've tried one thing so far. What I did was use a custom item renderer that checks for a value in the data property upon a FlexEvent.DATA_CHANGE event. If that value is not set, I tried setting the item renderer's selectable property to false. This, unfortunately, does not seem to work.

I am using a combo-box as a Datagrid ItemEditor (Not just Renderer, my Renderer is a Label, double clicking on a cell makes the combo-box visible, as is the case with all item editors) Now, selecting one of the entries in the combo-box is no problem. But my problem is only when i select the "Fruit", which in turn pops open another layer called "Select Fruit" dialog
Questions: How do i keep item editor, while the focus is on the layer; right now as soon as i click on the fruit, my handler popsup the "Select Fruit" dialog and the focus is on the layer. Once the focus goes out of the editor, the ItemEditor goes away and ItemRenderer label comes back. I want to keep the ItemEditor alive! where do I hook up interms of events like begin/end ItemEdit etc?

I'm trying to intercept the value that is taken from a DataGrid's GridColumn's itemRenderer and applied to the itemEditor, and vice-versa. I need to be able to format this value. However, my project is complex, so I may be focusing on the wrong idea in what I'm trying to accomplish.
I have a Spark DataGrid component (with ID dg) that I am dynamically populating from XML. I create an ArrayCollection from some nodes, and a regular Array from sub-nodes that is added as a property of the ArrayCollection. That ArrayCollection is then used as the dataProvider for the DataGrid.
Here is an example segment of a typical XML node and it's sub-nodes:
<item name="physOrderTable" text="" type="notes">
<cols>
<col id="0" text="Day/Time" />
[Code].....
This is the only method I've been able to use to achieve the desired result. This all works fine, if all I want to do is merely display information. But I need to be able to edit the values in each cell, and apply this back to the dataProvider, as I need to rebuild XML with the updated values later.
I have tried everything I can possibly think of to be able to do this. I built my own itemRenderer, then my own itemEditor, then scrapped them because it felt like I was re-inventing the wheel. But was I? I tried reading through the code for the DataGrid, GridColumn, and related classes, but I couldn't find any reference to the itemEditor beyond it being an IFactory. I have no idea where or how it tells that IFactory to be a text input or whatever it is.
Here is my issue:
When I turn on the DataGrid's editing, and double-click a cell, it takes the entire array of the col dataField for that column's cell, converts that array to a string, and displays the entire string in the edit text box. If I cancel the editing, or save the editing, it sets the string to the .col property. Then the labelFunction tries reading that string as an array, and it crashes. I was able to get the typeof the col dataField and converting it to an array if it's a string, but I shouldn't have to.
I need to have it display just the value of the cell for that particular row and column when the instance of the itemEditor is created. When that value is changed, I need it to apply back to that column's index in the .col array of the dataProvider. So, similarly to how it displays information in the labelFunction, I need to edit the information and send it back.
I've seen lots of custom itemEditors and itemRenderers for GridColumns, but these are hard-coded in the MXML. My grid is almost entirely dynamically created, so that's unfortunately not an option for me, as I won't even know how many columns or rows there will be when the DataGrid is created. I tried using rendererIsEditor, but that only seems to be on the MXML instantiation of the GridColumn, as there's only rendererIsEditable in the ActionScript, and it doesn't seem to work (or I don't know how to use it as intended).

I'm creating a mobile app in which I need to show a calendar with months at the top. The months are part of a component that extends from SkinnableDataContainer (and has some custom scrolling/behaviour - which is why I did'nt use a spark list). I need the months to be shown as a 'trapezium' shaped tab and so I'm using a png image as a mask in the item renderer for the component.
When the mask is not applied, it all works well - the months render, the list/data container selection works when I click on a month and so on.When the mask is applied, it renders well, scrolling and everything else seems to work well - but when I click on a month, nothing happens visually. And from the trace statements in my code, it appears list item selection is not changing. Looks like mouse clicks are not working.
Code:
public class TopCalendarMonthRenderer extends LabelItemRenderer {
[Embed(source="/assets/trapezium_alpha.png")]
private static var TrapeziumMask:Class;
private static var trapeziumMaskInstance:BitmapAsset;
[code]...

In this app that has an inline item editor, if you click on a location cell then press tab, the value in the location cell is wiped out.
focusOut doesn't work, nor could I get this to work in DataGrid itemEditEnding etc.

My application has a tree with a custom item renderer, which depending on the type of data at a leaf uses different components as editors. In one case I am trying to use a datagrid so that the user can choose a row that meets his needs (several columns need to be displayed), ie. similar in concept to a ComboBox.To do this I have a function assigned to be the handler for 'itemEditBegin' (for the tree) in which I'm dynamically creating the datagrid, and then using the popup manager to display it as a (modal) popup. So far so good.
However, if you click anywhere (eg. scroll down button in the datagrid) the popup disappears because the itemEditEnd event is fired - why ?In another scenario, I have a DateField setup as the editor, and the user can click on the icon to bring up a DateChooser, scroll through the months, etc. I looked at the code behind this, and it is using a popup, seemingly in exactly the same way as my code !Here is the 'itemEditBegin' code:
dataGrid = new DataGrid();
dataGrid.dataProvider = mddTable.dataCollection;
dataGrid.editable = false;
[code]......

issue is that when a user clicks a datagrid cell that has a combobox editor and then immediately clicks away from the cell, the text value in that cell disappears. I have an itemEditEnd handler on the datagrid and it shows the value of the property I use as the editorDataField just fine. But the labelFunction (which gets called after the itemEditEnd handler) on that grid column sees it as zero. Why aren't the labelFunction and item editor playing together nicely? Here is the DataGridColumn:

I can still keep the color of selected item even if it's rolled over? In my code, I have specified both the selectionColor and rollOverColor as below:
videoList.selectionColor = "0xCC0033"; //red
videoList.rollOverColor = "0xE9F3FF" //light-blue
It works well except when the selected item is rolled over. When the selected item is rolled over, it changes the color from red to light-blue. I want the selected item to stay red even when it's rolled over, but haven't found a way to achieve this.

I have a data grid with a custom item editor that displays a DropDownList component. When I click the scroll bar in the component, it is firing a focus out event on the list, which is causing itemEditEnd to fire. Why the list is not keeping focus, or how to make it keep focus. I'm using Flex 4.

I have a DataGrid, with itemEditor as NumericStepper in a few columns. When a value in the DataGrid is edited, I would like to update several values displayed on the screen, and so want to call a updateValues() function.First, I added this function to itemEditEnd event of the DataGrid, but the function is getting called before the new value is updated into the dataProvider and hence, the values I have in the function are the old values. Is there any other event that is fired after the values are updated into the dataProvider? or am I missing something?Second, I tried putting this function in the change event of each itemEditor (duh!), but then again, the change event is fired, but the values in the dataProvider are the old ones.Is there any way I can make the function updateValues() be called, every time a value is edited AND updated into the dataProvider, because there's where I am taking the values from?

i have the following code in which im trying to add an item in a List Component which instance has been named "box". That "trace" function used there returns me "_level0.Game.replayMenu.box", so im not pointing to something undefined...
this = _root.Game.ui;
this._parent.attachMovie ("replayMenu","replayMenu",this._parent.getNextHig hestDepth ());
this._parent.replayMenu._x = 450;
this._parent.replayMenu._y = 250;
trace(this._parent.replayMenu.box);
this._parent.replayMenu.box.addItem("blablabla","b lablabla");
The problem is that my list simply doesn�t add any items at all, i've already tried using addItem({label:"blablabla", data:"blablabla"}), but it just don�t work.

I have a list of objects containing an icon, a label, and a tooltip. I want to show only the icon and the label. The tooltips should be visible on mouse over an item.
Is there a way i can achieve this without writing my own mouse-over/out functions?
(notice that dataTips are a different thing as they are displayed only when the label is cut)

When would you want to use removeAll() vs just new ArrayCollection when you want to clear an array collection. Remove all iterates though each item in the list. I can't see a case when I would want to use it.

I have a List with textInput as itemrenderer. Initially the list is loaded with data from a data provider. However since the items are rendered in textInputs, I have the ability to change the value of a particular item.
But when trying to access the value of the changed item using the function below, I still get the old value in my trace:
private function addItem(event:Event):void {
trace(myDataProvider.getItemAt(myList.selectedIndex).label);
}
what I need to do for the new value to be available. My itemrenderer is shown below:

But when I check the value (trace()), the value is [object Object] and I can't seem to access the actual value of the object. Here is what I am doing:
