In one of the application I am working, List has been used. I am required to display items in the form of tiles. I do not want to change the component as of now. Is there any way to achieve this layout in list only.

need to fill a grid with tiles that will be of different sizes,but all multiples of the stage size - something like this:I want to randomize number of tiles placed into the grid without having any tile overlap. It will then place a tile at a random position on the grid, but not in any grid cells that have already been covered by a tile. And...also I want the grid/tiles to be dynamic enough to scale if the stage is resized.
View 14 Repliesi have made a list control. i want to display the name of the objects in it in a text control box
the code i am using here is
public function add(event:MouseEvent):void
{
var str:String;
str = mylistcontrol.dataProvider.getItemAt(0).toString();

The problem with this code is i am using index value of 0. however i want to display the name of object on which i have clicked or which is highlighted.
I need a List that resizes to exactly fit its content, unless that height exceeds its (dynamically sized) parent container. My requirements are as follows:
The component extends List, or at least acts similarly. variableRowHeight and wordWrap both equal to true. The height of the list cannot be less than minHeight (roughly 32px for scrollbar arrows). The height of the list cannot be greater than the height of the parent container .
Note that the parent container can be resized dynamically.
The height of the list should be updated as the size of both the contents and parent container changes.
Live updating would be preferable but not necessary.
There should be no scrollbars if the content height is less than the parent container height (sounds obvious, but I've had trouble with this too).
The trouble is that with variableRowHeight and wordWrap, it's very hard to know the size of the content at any given time. If the parent container's width is reduced, a line wrap may occur in the list which will change the height of the content. I know I can measure the height of the list content using measureHeightOfItems() + viewMetrics.top + viewMetrics.bottom, but when should I calculate that? What events should I listen for? And the thing I've had the most trouble with - when should I calculate it to set the size initially (i.e. just as the content has finished populating)?
Flex 3 List control had a itemRollOver event. Flex 4 List doesn't have it. Is there an equivalent or a workaround for this issue?

(i couldnt find any in the api) is there a method that can be overridden by extending the tilelayerbase class

View 12 RepliesI am having this very weird behavior with a mx:List control not scrolling properly.Here is a snippet:
<mx:List itemRenderer="customerRender" x="19" y="257" height="68" width="290" id="orderStatusHistoryList" color="#CCCCCC" rowHeight="35" ></mx:List>
The custom render creates a vBox that is 35 pixels high with some labels in it.Now, my dataProvider, set in the script block,is returning 3 items for the list (say item1, item2 and item3). Because of the height of the list control, only 2 are shown initially.Now for the weird part, when I scroll down the list to see the next item it is all messed up.
Initial display:
Item 1
Item 2
Display after clicking the scroll down button:
Item 2 (expected)
Item 1 (What the ?, this should be item 3)
Display after click the scroll down button one more time:
Item 1 (all wrong)
Now, if I increase the height of the list control,so it has enough room to display all three items, it displays fine.Also,I put a trace statement is the item render and flex is rendering all three items with the correct data.
I have a list in flex mobile project which contains multiple rows. I want to set color of specific rows based on some logic.
View 1 RepliesI'm building a mobile app, using spark list control. When user tap on a list item, i want it to navigate to that correspondence page

how do i code it so that when user tap on item label="Page One" it will navigate to PageOneView.mxml and if it tap on "Page Two" it will go to PageTwoView.mxml and so on.
I am trying to implement a drag and drop function between a list control and a columnchart in Flex3. List items should, when dragged and dropped on the chart, be displayed raphically in the columnchart.Alas, dropping the listitems on the chart does not seem to result in a proper graph.Here my code till so far with regard to the drop part:
private function doDragDrop(event:DragEvent):void{
var ds:DragSource = event.dragSource;
var dropTarget:ChartBase=ChartBase(event.currentTarget);

I have a s:List where I've defined my own itemRenderer, and would like to insert a horizontal line separating items, similar to the way the mx:LinkBar works. I don't want to have a line at the top or bottom of the list, so I can't just include an upper or lower border in the itemRenderer. I was hoping the itemRenderer could be made aware of its index in the list, but I don't see how.
View 2 RepliesThe following code display a list of comments using List control. The item height set to a fixed value (150), so it seems working: if the content is too long, the scrollbar shows. However, what I really want is not to set the height but let it to change according to the content size. Is there any way to accomplish this?
<mx:List id="commentList" width="100%" dataProvider="{commentSet.commentArrayColl}" rowCount="{commentSet.commentArrayColl.length}" >
<mx:itemRenderer> <mx:Component>
<mx:VBox width="100%" height="150" >
<mx:Text text="{data.commentContent}" />
<mx:Text text="{data.username} ({data.modified})"/>
</mx:VBox> </mx:Component>
</mx:itemRenderer> </mx:List>
To be more clear, I don't want to set the itemRenderer's VBox height to "150" or any other fixed value - but it'll only show one line of the text if I don't do it. So I'm looking for a way out of this. (If the VBox is not inside the itemRenderer, it'll auto adjust height as Text field string length grows - that's what I want.)

View 1 RepliesI created a list control at runtime as following:
[Code]....
//Where myDataArray is an ArrayCollection consisting of my Custom ValueObjects. When i execute the code it displays my list with custom item renderer, which is fine. But when bring my mouse over it, it doesn't give any colour highlight which means it is not selecting. Secondly, when i click on any of the list item, it doesn't dispatch any change event. I tried a lot but couldn't understand it.
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 have a spark List control. it has a dataProvider that shows reply from twitter search.i have created a function for change handler like this:
protected function list_changeHandler(event:IndexChangeEvent):void
{
ta.text = coverflow.selectedItem.title;
}
so, whenever i select each of the items in the List i will see the message(ta.text)but now, instead of me manually clicking the first time, i want it to automatically click/select the first item and see the first message(ta.text)how do i do it?
I have a list control and i want the user to be able to select many items at a time. Thus I want it to act that if the control key is pressed while he is clicking. Eg if he clicks on a selected row it should become unselected and if he clicks on a unselected row it should become selected.
View 1 RepliesI am trying to make a generic list control that has x buttons in it so that users can remove items from the list by clicking the x button. However, this list control needs to support item renderers while still standardizing the layout of items placed next to x buttons.
So I figure the best approach would be to extend the list control and use a renderer that draws the x button and combines that with what ever renderer the user supplies. Unfortunately I cannot figure out how to do that.
I tried overriding newInstance method from the IFactory interface and used that to create an HBox that contains my button and inserts the newInstance result from a user supplied renderer, however it wasn't complete. It displayed as I expected, but the mouse over effect only worked on the user supplied renderer portion and not the entire HBox that my custom renderer made.
I am using a spark list control to display certain items with my custom Item Renderer. I am trying to achieve the following: (1) show a separating line between rows in my list control (2) even when not a single row has been added, I want a horizontal grid lines to be displayed in the background
I am not sure whether (1) and (2) can be achieved in one go. I can solve (1) by modifying my item renderer to have a border, I guess. But I want to know whether there is a better or more conventional way.
Is there a direct way to get the item index of the data inside an itemRenderer? I need to display the item number against each item. I am currently doing a workaround and won't allow reuse of my itemRenderer component.
var index:int = model.dataColl.getItemIndex(data) + 1;
itemNo = index.toString();
This is what i am using now, it works, but the concepts of component reuse and data abstraction are compromised.

I am trying to display a list of items in a datagrid from a XMLList.
<Series no="1">
<file>
<filenum>1</epnum>
<prodnum>4V01</prodnum>
[code]...
My current code allows me to retrieve every Series into an XMLList and then i have a nesteddatagrid class that allows me to do things like.
<classes:NestedDataGrid width="100%" height="100%" id="gridFiles" dataProvider="{filesList}" >
<classes:columns>
<mx:DataGridColumn headerText="Season" dataField="@no" width="60"/>
[code]...
However this displays the datagrid with two rows, the first row has 1 in the Series column and then the two files crammed into the second cell in the same row. The second row is the same but has the number 2 in the Series column and the two series #2 files crammed into the cell next to it.If i do not use the nested data class i can pull the files using Series.file instead and all 4 of the files list correctly, however i do not get the Series number for each...
I have an embedded image asset (with a scale9 grid), and I'm trying to get the bitmapdata when it's resized, but I can't seem to do this without adding it to the display list.
I try this:
spriteAsset.setActualSize(w,h);
spriteAsset.width = w;
bmd.draw(spriteAsset);
But when I then draw out the bitmapdata with graphics.beginBitmapFill(), I just get the original un-stretched image.
Or do I need to take 9 separate BitmapData images and make 9 separate bitmap fills?
