I have a display object container and I am trying to add a paste event to it. But the event is not being registered. The documentation at liveDocs mentions that classes that derive from Interactive objects can dispatch paste event but I dont understand why it wouldnt work for me.
View 1 RepliesprintableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
I am trying to figure out how to override the default paste logic in a Flex 4 DataGrid ItemRenderer. Does anyone know how to do this?I am trying to capture the event when a user hits Ctrl-V while a cell in the DataGrid has focus and override the logic there.
View 1 RepliesI am loading an xml configuration file and based upon values obtained from it, I am connecting to an xml socket in the server.
But I can't register for socket.onConnect Function now. I could do it in my old cold in which I didn't use a configuration file. The configuration values are loaded properly. It seems the issue is in the way, socket.OnConnect function is registered.

I'd like to simply scale down a movieclip (that I'm treating as a button) when the user presses their mouse button. When users release the mouse button, I want my button to scale back to it's normal (.scaleX = .scaleY = 1) size. My button also has listereners for a ROLL_OUT event to turn off (.alpha = 0) a highlight movieclip that rests atop movieclips showing the different states the button can be in.
When I roll over the button, the higlight comes, but there is an annoying flicker problem. For some odd reason, when I press the mouse button the ROLL_OUT event handler function is called, yet I didn't scale the movie down enough for the cursor to be off of the actual button itself. I do not want that flicker. I'm not sure why ROLL_OUT is being called even though the event is clearly a mouse down, and within the mouse down event handler I am scaling the button movie clip, but not enough to remove out from under the cursor. In other words, if I click the button at its registration point, a flicker appears.
Here's my code.
//this add all the appropriate listeners to the button private function addMouseListeners() { this.addEventListener(MouseEvent.MOUSE_OVER, mouseOver); this.addEventListener(MouseEvent.MOUSE_DOWN, mouseDown); this.addEventListener(MouseEvent.ROLL_OUT, rollOut); this.addEventListener(MouseEvent.MOUSE_UP, mouseUp); }

why my rollOut function is being called when the mouse button is pressed, and called once more when the mouse button is released.
I'm trying to get a class file from Flash into Builder.Everything in that class sits inside a Sprite called mainContainer. Now I'm trying to get that `mainContainer' which hold the graphics for the class into a Flex Application.This is proving to be a problem as their are many various ways of doing it (it seems going by numerous Google searches).First off I declare an MXML Canvas with an Image inside it (as I read would work):
<mx:Canvas x="268" y="10" width="756" height="680" id="canvas">
<mx:Image id="spriteLayer" x="268" y="0" width="756" height="700" scaleContent="false" autoLoad="true">

Flash says I can only use the Clipboard.getData only in a PASTE event. (CS4 & AS3)
But I don't know how to make a paste event?
I would like to know the internals of that method, in other words what exactly happens when I call that method. If someone can explian it with a list 1,2,3... would be great. including events..
and the addElement method too, if is possible.

View 3 RepliesTextfields currently do not dispatch paste events. When the user is using keyboard shortcuts to paste, there's a way to workaround that shortcoming by listening to various keyboard events in the textfield. Is there a way to detect the paste event when it is originated from a click on the ContextMenu?
View 1 RepliesI see this type of apparent magic in all sorts of AS3 code, but here is a reduced example:
[Code]...
As indicated in the code comment, the loader variable should fall out of scope after the URLLoaderExample constructor. However... it still seems to be kept alive (not garbage collected) somewhere since the onComplete listener/handler is able to receive it cleanly. Where is the magic/hidden/global reference to loader that keeps it alive so that it can complete it's load operation, and then be handed to the onComplete listener/callback? Can this reference be seen somewhere?
To help with context... as a similar example, I know that the loader instance will have the onComplete listener registered. I also know I need to be careful to use removeEventListener at all times (?) to avoid potential memory leaks resulting from stranded listeners. What concerns me is that I don't understand where the magic loader reference is and whether (or when) I need to clean that up.
Our users want to copy and paste some rows from an Excel spreadsheet, or a chart generated in Excel, into a text box within a Flex application.It would be ok for it not to be fully functional, like an ActiveX object, embedded in the flex app. If it converted it to a static image, that would be fine. But I don't know of any Flex component that supports this.

Is it possible to capture rich text when pasting into Flash? Using a Flex TextEditArea, I can paste richly formatted text within Flash itself, but if I try to paste from an external source (say web page, microsoft word, etc) it comes in as plain text. Same for the reverse: if I copy rich text from within Flash, and paste to an external source, it goes out as plain text.
View 2 RepliesI need to disable pasting text in a textinout (flex3) : CTRL+V
View 2 RepliesUsers need to be able to paste the contents of an Excel spreadsheet into a grid in my flex application. I have implemented this using a TextArea with a change event handler that parses the text the the user pastes - splitting it up by newlines and tabs - and adding it to the ArrayCollection that is bound to the grid. However, it makes no sense for users to be able to manually enter text into the TextArea. How can I prevent them from doing so?
View 1 RepliesI know that you can use the context menu using a right-mouse-click in a control to choose to cut, copy, paste, etc. I've also noticed that you can use the windows keyboard shortcuts CTRL-C for Copy and CTRL-V for Paste.
Windows supports native CTRL-Insert (for copy) and SHIFT-Insert (for paste).
However, within Flex, it seems these do not appear to work. Has anyone been able to either allow these keyboard events?
I'd like to add copy and paste functionality to context menu in my Flex application. After creating a separate dummy project for testing, I realize that such options (cut, copy, paste, and delete) are already available in this dummy project without any coding. Both projects are compiled using Flex 4 SDK, run in the same brower (IE) and have the same version of Flash Player (10.2.153.1). However, different context menu are displayed. Here are the difference:
Orig Project: Print, Show Redraw Regions, Debugger, Settings, Global Settings, About Flash Player...
Dummy Porject: Cut, Copy, Paste, Delete, Select All, Settings, Global Settings, About Flash Player...

I'd like to know if is possible to trace the name of a container object using the contained object.Something like:

I'm creating an object that's only purpose is to hold a few other display objects, so all I need is a super class that can hold display objects. I don't want to use the sprite class because it has so many functions and properties that I don't need. if I can't use DisplayObjectContainer as a base class then what class should I use?
View 1 Repliesin ActionScript 3, if I loop through the children of a movie clip, it will return a DisplayObjectContainer, which is a list of DisplayObjects. However, the AS3 typeof cannot identify MovieClip as MovieClip is now an object, instead of a data type. How can I correctly identify MovieClip?I found 3 solutions online: First set the MovieClip name to a specific name, then in the iterate process, check the name of children using child.name.indexOf("specificName") > -1
Solution 2:use child.hasOwnProperty("numChildren") to identify a MovieClip
Solution 3: use 3rd party plug-in like FlashDevelop
I am converting a DisplayObjectContainer as a Bitmap using BitmapData.The DisplayObjectContainer has many DisplayObjects. I want to exclude few DisplayObjects while i tranform into Bitmap.Therefore the bitmap should not have that particular displayobjects alone.

I'd assume from this that there is no correcting done for children with the same name being added to the same parent. I ask this question because I'm creating a structure that needs to mimic the display list and I'd like to keep behavior consistent.
Another question: I'd assume internally the children are saved in something similar to a Dictionary object, does anyone know if this is true? And then getChildByName simply does a foreach loop and returns the first match on a name?
A DisplayObjectContainer's dimensions change based on its contents.
That can be a LOT of contents, many of them with visible = false or masked, thus making them hidden. Is there a way to get only the visible contents of a DisplayObjectContainer similar to a TextField has the textHeight property, which gives you the exact dimension of what you see on-screen.
is it possible to clip children that are part of a DisplayObjectContainer? If I have a parent object with size x 100, y 100, width 100, height 100 and a child that has the coordinates x -50, y -50, width 100, height 100, I can still see the full child staying at x 50, y 50, but I want the child to be cut off by the parent.
View 3 RepliesI have a class which will contain exactly one child, no more, no less, and other classes are not allowed to change that fact.
I could throw error messages every time a child is added or removed by overriding the default properties, but I don't want the object to be treated as if it were a DisplayObjectContainer.
I want it to look like only a DisplayObject, yet I still want to add a child to it in private.
I'm working on a class that let's you use "addChild" to add children to it. In all aspects, it's treated like a regular class, the only difference is that it doesn't really add them. It only draws the BitmapData of them and displays that, which doesn't make a huge difference for the user, but might make a difference for performance, at least the way I am planning to make it.
Now, if users add a regular old Sprite or other DisiplayObject to the container, I have overridden the function to draw the BitmapData of the item, and store the item in an array.The problem is, if the user want to do something like "sprite1.parent", since the Sprite technically isn't on the display list, the parent property will be null. I can't override the passed in sprite's properties, right? Is there any way around this?
