[flexcoders] converting to RTF in flex

[george_lui]

Hi,

I have a concept of a "form" in my flex app.  I have this requirement
where we want to export this "form" into an RTF formatted file.  Has
anyone ever done this before?  Do you know of any flex capabilities
that could assist me in implementing this?

Thanx,
George

Before I answer this, let me get some background.

Are you using J2EE security?  If so, FORM or BASIC authentication?

Subject: [flexcoders] Re: How to handle sessions in Flex

thanx for the prompt reply.  I neglected to mention some other
requirements.

The nature of our app can have our users spends a good deal amount of
time filling out the form. There's a save button there to save your
work.  However say the user is filling out the form and doesn't bother
to save the form.  There's a good chance that the session could expire
before he gets a chance to save the form.  Our server session is
usually 30 minutes.

In this scenario, when the session expires, we don't want the user to
lose the data on the form.  We want to somehow "catch" the session
timeout and save the form.

Another scenario we want to catch is, say you logout. The session is
invalidated.  However you could hit the browser "Back" button and have
the previous screen display.  You wouldn't know that the session time
out until you invoke a service call.  Instead I want to go to the
login screen in such a scenerio.

Can this be done? Please advise.

thx,
george

[flexcoders] Re: How to add labelFunc when dynamically creating a DataGrid

[Brendan Meutzner]

Kevin,

As long as the function reference is passed in through your column
object, you should be able to set it like you have already.

Here's an example using your creation method for the datagrid column:


http://www.macromedia.com/2003/mxml";
initialize="initPage()">

RE: [flexcoders] How to read the Drive and place list into Tree?

[Dekayd Media Inc.]

This is possible and pretty easy if you know how.

 

It took me a while to figure out though because there is no specific
documentation that tells you how.

 

 

I am going to assume you know how to use Flex Remote Objects to connect
to a CFC. If you don't it is well documented and worth figuring out.

 

Once you can connect to a CFC make a method in your CFC that looks
something like this:

 

 



  

  

  



 

 

Then you will have to use the query returned as a dataprovider for the
Tree Control.

 

Each time a user tries to open a folder you will have to make another
remote call and use the information returned to populate that folder in the
tree dataprovider.

 

 

Good luck eh

Re: [flexcoders] Re: How to add labelFunc when dynamically creating a DataGrid

[Sreejith Unnikrishnan]

Kevin,

Just replace the piece of code where you try to assign the labeFunction
with this.
The rest should be OK.

column.labelFunction =
Delegate.create(this, displayText);

Regards
Sree

the function, such as "displaySpecificText", so where is the method

Thanks again!

[flexcoders] paginating runtime objects.

[kronos113]

Hello all,

I'm having a bit of difficulty.

I've got a VBox component that is a combination of mxml declared 
components and objects added at runtime.  I need to page this for 
printing.  So I've created a script class that I pass the Container 
and the desired page lenght to.  I return an array of VBox's 
representing the individual pages that will be added to the print 
job for printing.

The issue I'm having.

I get an error #2006 (The supplied index is out of bounds) when I 
add the components to the output VBox's.  I can iterate through the 
children in the following way and print them all out fine.

for(var j:int=0;j pageHeight)
{
aRet.push(vbTemp);
vbTemp = new VBox();
iTotalHeight = 0;
}
vbTemp.addChildAt(child, i);
iTotalHeight += child.height;
 }

Anyone have any ideas?

Thanks
Kent

[flexcoders] Re: How to add labelFunc when dynamically creating a DataGrid

[Brendan Meutzner]

Hey Kevin,

If I understand correctly, how would this work...

//CellrendererClass.as/mxml

public var listOwner:DataGrid;
public var getCellIndex:Function;
public var item:Object;
public function setValue(str:String, item:Object, sel:String):Void 
{
var position:Object = getCellIndex();
var column:DataGridColumn =
DataGridColumn(listOwner.getColumnAt(position.columnIndex));

if(column.labelFunction != null)
{
return column.labelFunction(item);
}
this.item = item;
}


By obtaining a reference for the current column within the
cellrenderer, you can call the labelFunction within the setValue method.

Does this help?


Brendan

You'll need to expire the page with cache headers so that the browser

Thanks everyone for the reply.  That's what I was afraid of.  I was 
trying to avoid generating currency/date pattern for each locale to 
send to the formatter in Flex.  I hear that Flex 2.0 will provide i18n 
support, hopefully they provide Java-like support.

Hi Tracy,Thank you so much`-`I un installed the other version that I had, and installed the one with the "Integrated JRun4".

Flex is a J2EE application, so it must run under some servlet container.  If you are not a J2EE guy, and don't want to become one yet, install flex using the "Integrated JRun" option.  This will give you a working Flex installation immediately.  Your access urls will be: http://localhost:8700/flex/myApp/myAppMain.mxml http://localhost:8700/samples  If/when you find you want to serve Flex from IIS, you must move to some full web server, since the integrated JRun does not support the necessary connectors.

 easy to set up, and seems extremely stable.

Re: [flexcoders] How to create Validator via ActionScript

[Stanislav Zayarsky]

Thanks for the answer Matt,

But actually I have reviewed flex generated as file and now I know how
to create validator via ActionScript in 1.5 version.

Best regards
Stanislav

[flexcoders] How to add labelFunc when dynamically creating a DataGrid

[Kevin Ewok]

Hello all.
 
I have a form where a user enters criteria and chooses from a list box
the columns they want to see in their search results (in the form of a
datagrid). The List of columns is linked to  in a XML file.

I am able to generate the datagrid successfully along with cell
renderers, but I am not sure how to dynamically add a "labelFunc" b/c
there are several columns where I need to process the value before
displaying.

My code looks like this:

// Code to create Datagrid
// Loop through the 'column' objects defined in my xml Model and 
//   call createDataGridColumn method.

/* create column */
function createDataGridColumn(column : Object) : DataGridColumn 
 {
var _dgc:DataGridColumn = new DataGridColumn(column.name);
_dgc.headerText = column.headerText;
_dgc.width = column.width;  
if(column.labelFunction != undefined)
{   
_dgc.labelFunction = column.labelFunction;
//_dgc.labelFunction = "displayText";

}
return _dgc;
}

THE QUESTION OF THE HOUR is that the _dgc.labelFunction line within
the if statement is assigned the text of the method name, for example,
 in the commented line below. So where do I place the implementation
of this method???

The following attempts by me didn't work:
1.) I tried extending the DataGridColumn class and implementing the
method there. 
2.) Implement the method in the class of the code above.
3.) Implement the method in the calling class of the code above.

Thanks in advance for any help!

[flexcoders] Flex Builder 2 panel align

[Andy Johnston]

Hey all just wondering with this constraints based layout for Flex 
Builder 2 is it possible to simply align a Panel to centre of a liquid 
layout? Why can't you set x and y values to a %?

[flexcoders] Data provider for custom component

[kjlinboomer]

Hi all,

I have developed a custom component for use in flex. I have dropped it
into an MXML file and my init(), createChildren() etc functions are
all working and I can pass initial values into in like:



My question is how do I provide an external data provider for this
component?  Do I need to put flex's dataProvider class in the same
package as my component and then refer like this:


  
 {//some action script object here}
  


Not sure how this works...

Thanks!!

Keith
