[flexcoders] Loading Image files
I have a series of images in a viewstack. The stack changes its index using a timer and I have applied a fade effect between changes. The problem I am experiencing is that there is an interruption in the first fade effect as the image is being downloaded to the user's pc since they are not embedded images. Is there a way to preload an image before I try to display it so there is no gap in the fade effect?
[flexcoders] Re: Race conditions when event handlers triggered from different targets
--- In flexcoders@yahoogroups.com, Gordon Smith gosm...@... wrote: Yes, that is what Alex is saying. Handler B will not begin before handler A finishes. Event handlers don't get paused. Furthermore, when you (or the Player) calls dispatchEvent(), all the event handlers listening for that event execute before dispatchEvent() returns. I really want to believe this assertion, and I hate to belabor the point, but I'm troubled by the observed behavior in the Debug Player under IE8. In this case, a run-time error was thrown by the handler of a network event and the standard dialog was displayed. This condition exposed a problem in our network message parser, which caused subsequent network events to also display run-time errors. I was unsettled to find that a new dialog was displayed, and a new Windows OS-level thread created with each run-time error, even though I hadn't dismissed the initial error dialog. It appeared that the network event handler code executed and threw a run-time exception with each message received from the network, regardless. This would seem to be an exception to the behavior stated above; does a run-time error dialog cause the execution context to pause and allow other event handlers to be executed? If so, is this only possible in the Debug Player, or do we have to worry about protecting against possible re-entrance in handlers that access global data?

MessageService service = (MessageService)getDestination().getService(); // And even if I could get the service, how do I send it to a specific channel? // And if I send a message how do I hear back from the channel?

It is good enough if you shipped it and got paid J If you want to post the code for a renderer, we can offer opinions on the pros and cons of your implementation. It might be good education for many. I don’t have time to judge dozens of renderers so we can just start with one of yours and discuss it. There is usually a trade-off of ease of programming vs performance and memory optimization. The smaller and faster you want it to be, the more work you have to do.

RE: [flexcoders] Re: Race conditions when event handlers triggered from different targets
IMHO, Once you get the runtime error dialog, all further behavior is undefined. Your code has finished executing and the player is no longer executing its standard workflow.

Handler B will not begin before handler A finishes. Event handlers don't get paused. Furthermore, when you (or the Player) calls dispatchEvent(), all the event handlers listening for that event execute before dispatchEvent() returns. I really want to believe this assertion, and I hate to belabor the point, but I'm troubled by the observed behavior in the Debug Player under IE8. In this case, a run-time error was thrown by the handler of a network event and the standard dialog was displayed. This condition exposed a problem in our network message parser, which caused subsequent network events to also display run-time errors. I was unsettled to find that a new dialog was displayed, and a new Window! s OS-level thread created with each run-time error, even though I hadn't dismissed the initial error dialog. It appeared that the network event handler code executed and threw a run-time exception with each message received from the network, regardless. This would seem to be an exception to the behavior stated above; does a run-time error dialog cause the execution context to pause and allow other event handlers to be executed? If so, is this only possible in the Debug Player, or do we have to worry about protecting against possible re-entrance in handlers that access global data?

[flexcoders] Beginner Questions
Hello. I am very new to both Flash and Flex. I've been programming video games in C/C++ for a while now and thought I'd try something faster to develop. So, I have a few questions, specifically geared towards games development. Do games developers usually use Flex or just raw Flash? Is just using the Flex open source compiler viable or is purchasing the Flex Builder pretty instrumental to effective use of the language? Is there a heavy preference between vector art or bitmap art in flash development? Is the code significantly different between the two? I'm sure I'll have more questions, but I'll kick it off with these. Thanks in advance. -moo

[flexcoders] Label Control Text Value Coming From a Function Call
Hi FlexCoders,
I have a label control where the text value that should be displayed is coming
from a defined function.
For example:
mx:Label id=LabelDay1 text= horizontalCenter=true /
private function setDayName(monthNo:Number, dayNo:Number,
yearNo:Number):String
{
// Make some calculations on the day based on the date parameter passed.
//..
.
//Assuming the day value is returned after parsing the date value parameters.
return 'Monday'
}
Is it possible to assign that the LabelDay1 object would display in the text
the value returned by the function setDayName. Please take note that I have a
lot of instances of the label control which is inside a datagrid column
control's header renderer so placing them in a function outside would be
tedious.
Would this be possible:
mx:Label id=LabelDay1 text={setDayName(1,1,2009)}
horizontalCenter=true /
Appreciate your response. Thanks.

Angelo
[flexcoders] Positioning using the graphics class?
I am using the Graphics class to draw borders on a Canvas. I think I do not understand how the positioning works. For example, I set lineStyle to width of 3 and some color, then I use drawRect and specify x=0, y=0, width = canvas.width and height = canvas.height. I am expecting a 3 pixel border within the canvas. But that is not what I see. Instead, all of the drawn lines are partially clipped by the canvas. With drawRect, what is the relation between the x,y, width, height, and the line width? I am trying to figure this out by trial and error, but have not been able to infer the rules.

[flexcoders] AdvancedDataGrid itemOpen() to resize Container
Hi, I have a Windowshade as a root component; the child is an AdvancedDataGrid. I want the Windowshade to scale as a user expands/collapses a row in the DataGrid. So I trap the itemOpen and itemClose events and I try to adjust the height of the Windowshade like this: this.owner.measuredHeight = grid.height; this.owner.measuredWidth = grid.width; But it does nothing. I thought using measuredHeight and measuredWidth was the way to go when resizing at run-time. Has anyone come across this before? Any tips are, again, very much appreciated.
