It’s a bit tricky because of some missing pieces in the underlying Flash focus APIs and because of how Focus events work. Here is my take on how to do it. Usual caveats apply (i.e, code is not supported and may have bugs etc).

You can enable the hand cursor on a MovieClip by defining the following statement

MovieClip.buttonMode = true;

However the solution does not work in-case you have a dynamic textField in that movieclip. To enable hand in this case you have to additionally write the following statement

MovieClip.mouseChildren = false;

The reason is that the mouseChildren property determines whether or not the children of the object are mouse enabled. If an object is mouse enabled, a user can interact with it by using a mouse. The default is true which makes the dynamic textfield interactable and due to the textfield behaviour the flash player does not show the hand-cursor.

The approach followed here is by using the getDefinitionByName utility which interprets the string and convert it into a Class. Then you can use a new syntax with that particular class. Following is a code for the same solution and you can download the source files from here. The “testMC” here is a movieClip in library with the className as testMC and BaseClass as flash.display.MovieClip

import flash.utils.getDefinitionByName;


function addMovieFromLibrary(mcIName:String){
var tMC:Class = getDefinitionByName(mcIName) as Class;
var newMc:MovieClip = new tMC() as MovieClip;
addChild(newMc);
}

private function dgItemClick(event:ListEvent):void{
if (event.columnIndex != 3) //to check if the button has not been clicked
loadItem(event.itemRenderer.data);
}

public function loadItem(dataObj:Object):void{
var str:String = “”;
for (var items:String in dataObj)
{
if (items != “mx_internal_uid”)//this is an extra unique id that Flex assigns by itself
str += items + “:” + dataObj[items] + “\n”;
}
Alert.show(str);
}

4c) Add the property TraceOutputFileName to mm.cfg

OSX -

TraceOutputFileName=MacHD:Users:username esktop:flashlog.txt

Windows -

TraceOutputFileName=C:\Documents and Settings\username\Desktop\flashlog.txt

Create a shortcut to the batch file to set the Command Prompt colors and options

Right-click on the batch file and select “Create Shortcut”

Right-click on the shortcut and select “Properties”

To view the Command Prompt maximized change the pulldown under “Run:”
To change the colors of the Command Prompt select the “Colors” tab
Unfortunately the “Font” tab options are very limited
Under the “Options” tab, select “QuickEdit mode” to be able to easily select and copy and paste
Tip for copying and pasting in the Command Prompt:
Select the text you want to copy and then right-click it, this puts the selected text into the clipboard … now just hit ctrl-v or paste in any other program.

Close out of the properties and double-click on the shortcut to see the flashlog with your colors and options.

General Known Issues in Flash Player 9.0

· Flash Player cannot progressively load files that are greater than 2Gb

· UILoader ignores scaleContent when content is loaded through loadBytes

· Memory utilization could substantially increase when large numbers of bitmaps that are subject to mipmapping are loaded

· Flash Player supports up to 30 frames per second playback for video.

· Opera and Netscape do not allow recursive calls using the ExternalInterface API into the Flash Player. This issue has been reported to Opera and Netscape.

· In certain browsers, full-screen does not render correctly when the window is split between two monitors where one monitor has a higher resolution than the other.

· Socket connecting to port under 1024 throws ioError, not securityError

· When using the Flex profiler, if FlashPlayerTrust is incorrectly created as a file, the Flex profiler will crash. Please ensure FlashPlayerTrust is properly configured as a directory.

· On the Windows standalone Flash Player, empty POST actions are changed to GET.

· Subsequent loads of ActionScript 2.0 SWFs containing components into a parent ActionScript 3.0 SWF may cause some components to break. The components will work on the first load, but loading new, or unloading ActionScript 2.0 components of the same class may exhibit this behavior.

· Developers should not rely on garbage collection if immediate clean up of active objects, such as display objects, streams and media, is expected. Use the appropriate ActionScript 3.0 APIs (close, removeEvent Listener, etc.) to get immediate behavior when cleaning up active objects.

· The delete operator is intended to remove properties of an object, and cannot be used to remove members of a class. For more details on the delete operator, see the ActionScript 3.0 Language Reference.

· Flash Player sound input does not work for OSX Audio MIDI sample rate settings higher than 48Khz. The microphone will either record noise or nothing. Some third party applications and MIDI breakout boxes will change the systemwide Audio settings on launch, and fail to return settings to default on close. To workaround this issue, go to Applications-> Utilities-> Audio MIDI Setup. Select Sound Input and change the properties for the ‘Built-in Input’ and/or ‘Built-in Microphone’ to a setting less than or equal to 48Khz.

· The standalone player cannot self-register SWF and FLV file associations under Vista without administrator privileges. Workaround: Users should launch SAFlashPlayer.exe once with administrator privileges by right-clicking on the EXE and selecting “Run as administrator” so it can correctly set the registry properties.

· Bitmap effects and filters cannot be printed.

· Button label text may not redraw correctly upon exiting full screen mode. User must mouse over the text to force the redraw.

· Transform Matrix transformations are not reflected in respective MovieClip/DisplayObject properties. Properties like scaleX, scaleY, and rotation are not changed as the result of changes to a DisplayObject’s transformation matrix (flash.geom.Transform, flash.geom.Matrix). However, changes to those properties are reflected in the matrix. If you change a property after changing the matrix, the matrix also resets to its original value. Affects ActionScript 2.0 and ActionScript 3.0. Workaround: If using matrix transformations, avoid using scaleX, scaleY, and rotation in favor of their respective matrix transformations.

· Triggering stage.invalidate() during a “render” event listener fails.

· Empty strings passed through External Interface API via JavaScript are converted to null.

· Some users are experiencing sound problems under Windows due to lack of support for WaveOut with drivers for some video cards, such as Realtek and SoundMax.

· Launching the context menu when in full-screen mode may temporarily reduce FLV video playback performance on Macintosh systems.

· Although full-screen mode does not support text input, the text input cursor will display over input text fields. Workaround: dynamically convert input fields to dynamic text fields or disable TextInput components when in full-screen mode.

• Generic Functions: This functionality will add Java-style method overloading to ActionScript. A function must be defined with the keyword generic, but then mutliple methods (with different method signatures) can be used.
• Iterators and Generators: Increased support for iterating over a series of values using a class defined iterator. Both of these items are very Python-like.
• Proper Tail Calls: A function can properly call another function as its last operation – this adds increased support for recursion patterns.
• New Number Types: byte, double, decimal (and the current generic ‘Number’ type would be removed)
• Numeric Suffixes: As in Java, numeric literals will have suffixes to denote their specific numeric type.
• Vector Type: As in Java, there will be a mono-typed array called Vector. Length can optionally be pre-defined at creation.
• Record Type: Describes the details of an object – easier to create than a class. I believe it is dynamic – in that it has required values, but additional properties can be defined per instance.
• Array Type: A type that describes what will be contained within an array. For example – you could say that you will have a 7-element array made up of Strings.
• Union Types: A property (or argument) could be one of a list of types (as opposed to now where a property has to be of one type – or no type). This would give you the ability to have an argument that could be a String or XML – but nothing else.
