Re: [flexcoders]PHP and Flex questions
When a Flex application in a browser communicates with a php page for the first time a session is created. This is the same behavior as user receiving a PHP page in their browser. - true , but the session is created only if the php installed in your server is configured to auto start a session or you manually start the session in your scrip. - This session that is created last indefinitely with Flex applications because Flex keeps the connection open / session alive on the server. I am not sure if this is 100% true , but i believe by default , the http headers send Connection: Keep-Alive, so sessions remain alive. In my application it works okay, session doesn't expire while flex application runs. However, I believe if you send custom HTTP headers this behavior can be lost. - Flex keeps the connection alive by periodically pinging the server. same as above - Sessions will never timeout due to this behavior. same as above - When the user navigates away from the Flex application the session will timeout on the server. true , it will timeout in the time specified in your php.ini To manually timeout a session on the server call a page or function that executes this code " session.destroy( );" <-- not sure what the recommended method to clear the session on the server. - true , depending on your php session you will call the correct function to destroy the session Hope this helps. - Original Message From: dorkie dork from dorktown <[EMAIL PROTECTED]> To: flexcoders@yahoogroups.com Sent: Tuesday, April 3, 2007 8:37:15 PM Subject: [flexcoders]PHP and Flex questions Can someone tell me if these statements are true or false and if false what is the correct answer? - When a Flex application in a browser communicates with a php page for the first time a session is created.

Re: [flexcoders] getChildren
only objects that inherit the Container class have this functions. When i have
a situation like yours, I usually do something like :
if ( obj is Container)
{
//code here
}
and it works fine. It is possible not to work if your object
was originally an Object , and you further created your
object using a class reference.

Re: [flexcoders] Drawing primitives in MXML
You can not use mxml to draw basic shapes because you have no components for these shapes. You have to use action script and draw into components graphics object.

I've been trying to get my head around Flex using Flex builder/Flex 2. Previously I've been working with SVG. So far, I've been unable to figure out how you draw primitive shapes (circles, rectangles, roundedrects etc) in MXML. I can see how to do it in ActionScript and append them to a Canvas that's been declared in MXML, but not how to create them declaratively in the MXML itself. This seems such a basic thing to want to do I can't imagine it is impossible, but so far can't find a way to do it. Is this possible? If so, how? Or am I thinking about this all wrong?

Re: [flexcoders] [Flex2] Binding an image using @Embed...
You also must check your build file for the 'use-network' flag. Quote :"A SWF file can access one type of external resource only, either local or over a network; it cannot access both types. You determine the type of access allowed by the SWF file using the use-network flag when you compile your application. When the use-network flag is set to false, you can access resources in the local file system, but not over the network. The default value is true, which allows you to access resources over the network, but not in the local file system.".This one skipped me when I first tried to display dynamic images , it gave me a headake , I was looking everywhere but not where I was supposed for the documentation .

Re: [flexcoders] Dynamically adding components to a panel?
Check the manuals , developers guide and building flex components , there is plenty of documentation.However , for your particular case , just add a click listener to the button , and on it do something likevar foo:Button = new Button();container.addChild(foo);for the shape thing , for each shape or object you want make a component. .Flex knows about dragging , on mouse down just call startDrag and on mouse down call endDrag , and create a new instanceof that particular component you want to place and init it's x and y properties with contentMouseX and contentMouseY.Hope this helps.- Original Message From: jack_freud <[EMAIL PROTECTED]>To: flexcoders@yahoogroups.comSent: Wednesday, October 4, 2006 9:48:01 PMSubject: [flexcoders] Dynamically adding components to a panel?

Ultimately I want to make a kind of toolbar or palette, where I could drag a shape from the palette into the workspace, and a copy of that shape would remain where I performed the drop.

Re: [flexcoders] Re: tabbing in flex
Thanks for your reply. I think you agree it's not clear enough in the documentation. It requires less time tolook in the source code than parsing the documentation. I have been trough theflex getting started , flex developer's guide, developing flex application documentations and I now have a general ideea about Flex , I have imagined going trough the API's is enough. A lot of custom componentsrequire focus , I dont't think it is an advanced topic. If you think about it , the UIComponent class documentation really gives you the impression focus is enabled by default . At least a note should be added there imho. Anyhow , your note is usefull for the next steps in my application , I now have an answer to my question , thanks .- Original Message From: stephenmartin2 <[EMAIL PROTECTED]>To: flexcoders@yahoogroups.comSent: Monday, September 25, 2006 8:42:40 PMSubject: [flexcoders] Re: tabbing in flex There is some mention of implementing IFocusManager in the doc.
