As of Flex 4, I'm using s:Group instead of mx:Canvas.
With s:Group , show event is not fired when the container is visible like with mx:Canvas. creationComplete event fire only once. How can I detect show event or something alike in Flex 4 or should I just use the mx:Canvas instead ?
I've a custom component where I do some graphics (e.g draw a line) and dynamically add a subcomponent (e.g a label) to it.
If I base the component off Group (which is recommended as per docs since its a spark component) then when I dynamically add a label the graphics part disappears.
However if I base it off Canvas this doesn't happen.
Why is that the case?
Here is the code.
MyComponent.as
public class MyComponent extends Group
{
public var x1:int;

I am working on a grid example in flex using advanced grid control. I know we can easily group data by specifying the field name. At the group node level, other than the gorup name I want to be able to show data in the rest of the cells ( calculated data ) and I am looking for some dataRowBound event or similar to be able to hook some data in it.
Example: Grid displaying list of towns grouped by state. At the group level ( for each state) I want to show the total number of towns in each state. Here how can i show the total number in the town column.
When I create something like the following:
<mx:DataGrid id"myDataGrid"
itemEditBegin="myDataGrid_itemEditBeginHandler(event)" />
When does the event listener for "itemEditBegin" get added and removed? Is this essentially the same as:
<mx:DataGrid id="myDataGrid"
creationComplete="myDataGrid_creationCompleteHandler(event)" />
protected function myDataGrid_creationCompleteHandler(event:FlexEvent):void
{
[Code]...
Basically, I'm wondering where I should add "myDataGrid.addEventListener" if I want to do it programmatically? Should it be in the creationComplete listener function of the object itself, or perhaps in the creationComplete listener function for whatever parent object it resides in?

I have a generalized media player web app that I wish to be able to use flash in. The client uploads the flash to a particular directory, and a webpage is produced automatically that houses that flash file. The output of this process currently looks something like this:

I am trying to get the flash to display using the original canvas size (540 x 400 by default) but every time I load this in chrome I get 300 x 150 and in IE the box is square.

Since flex memory management is poor, objects once instantiated dont die very easily (even when they go out of scope), one would need to check on various properties of components. I am using one such thing to know if the screen (which is a display object) is in current view. For this I am turning on a boolean property (currently visible), and I am setting it true on show event of the display object.
What I need to know is, which event (something opposite of show, e.g left?) could be used when the screen is replaced by another display object?
Something like focusIn and focusOut from dotnet.
Or if there is some property which could directly tell me if the display object is currently in view (hasFocus doesnt seem to be giving me expected results).
Create a tab navigator (or viewstack, whatever) and add a couple tabs. On your tab add a show event handler. Inside the event handler call invalidateProperties() and invalidateDisplayList() on one of the children of your tab. Put a break point on the childs commitProperties() and updateDisplayList(). You'll notice that the updateDisplayList() gets called before commitProperties() which results in incorrect behaviour.
I noticed this problem when setting a DataGrid's dataprovider from inside the show handler. Setting the dataProvider causes the grid to invalidate both properties and displayList, updateDisplayList() will get called first, then commitProperties() which will result in the grid not updating the rows. It appears the root of the problem is that the show event gets dispatched from within LayoutManagers validateDisplayList() loop, so invalidating a child object from within the show handler results in its updateDisplayList() getting called immediately.

I've been using Adobe Flash CS3 & CS4, and I still find it ridiculously hard to navigate around that Program sometimes, mainly when I have to deal with a Pre-made Flash website that needs Editing.Allot of people Label layers, Symbols, etc... poorly, so it's hard to find your way around.I would like to know if these is any Equivalent of "Show Transform Controls" (from Adobe Photoshop), in Adobe Flash CS4
I have loads of Layers to deal with, and the only way I can get to edit the Layer, is by double clicking on them, then I go to it's timeline and settings.Most of the times I can't even see some of these Layers/Buttons, as they appear invisible on the Stage/Preview Screen.How can I more easily Work with my Layers in Flash CS4?It would be allot easier, if I could click on the Layer in the Pallet, and see an outline of where it is on the Stage.Or if I could edit the settings of a Layer, by clicking something in the Layers Palette.
I am also trying to figure out how I can change the color of an image to Black/White, I only know how to do this with the Motion Tween Option, that gradually changes the color over those given seconds. I don't want an animation, just permanent color change.Also when I am moving a Object in one layer,when I exit and view a different layer, I see that the "Shared" object also moved there too, which I do not want.Is there any way to unlink these by chance?
I am using tab navigator. And it has thee tabs "Search", "Show as text", "Show on map" I have a address search box in Search tab. I would like to hide other two tabs if search has not happened yet. So if user hasn't searched any thing other two tabs shouldn't be visible.
View 1 RepliesI am developing a game wherein a gamer has to drag a clip to another clip. I load the destination clip by

What happens is the dragged object is seen beneath the destination clip including other destination clips loaded that way. I need the dragged object to be seen above all other clips. This is something like the Z-index in HTML. Is there anyway how I can do it?
I got a square component inside a canvas which when clicked shows a glow effect-indicating selection-while clicking somewhere else this effect is removed-indicating deselection.The problem is that the canvas always dispatches the "deselect" event, even if the mouse if over the square.I worked around this by defining a circumstantial function which removes the child's width,height from the parent's "clickable" area.Is there a better way to tell the canvas to dispatch his event only if not over the child ?

I am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)
Company Model Year No
GM Chevy 2010 10
GM Chevy 2009 5
GM Pontiac 2010 12
Honda Civic 2009 12
and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).
I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?
