[flexcoders] Re: cursor manager bug
This is a fact-of-life of how security in loaded SWFs works.
Assets in subordinate SWFs are not available to the top-level SWF,
but the cursorManager only can work in the top-level SWF.
The easy workaround is to put a DividedBox in the top-level movie and
hide it.
The more sophisticated workaround is to embed the assets you need in
the top-level SWF.

Well, if you are in no-source-code hell, then you have to hack your way out. If you know the internal structure of the loaded SWF, you can try to find the place the loadVars is done and try to grab a load event on it, or set a timer and check to see if the loadVars is complete.

[flexcoders] Re: Filesize generated swf's
An empty Application tag should come in at about 128Kb. Not sure why you got 263Kb. You sure you didn't have any custom theme attributes on the application tag? At any rate, starting from 128K, you'll hit your 150K limit really quick. However, I encourage you to consider the following: 1) Broadband is here. The main reason for a 150K limit is download time. More and more people are accessing your site over fast connections where 150K only represents 1/2 second or less 2) Flex/Flash is streaming media. The user will see the download progress bar, which you can customize, very quickly, long before the app has been fully downloaded over slow links, so you can present something to the user faster than you could trying to get one 150K HTML page parsed and rendered 3) Flex is not page-oriented. Thus once you get the SWF downloaded you don't have to go back to the server for the next screen full, it is already there. This is often much better than having to make the user wait as you go get the next 150Kb HTML page, and the one after that. Flex is a new paradigm. It will require you to think a little differently and design your apps differently, but you will probably find that there's a payback in terms of usability and productivity on the part of your users that is not achievable in the HTML paradigm. -Alex --- In flexcoders@yahoogroups.com, Joost Nuijten [EMAIL PROTECTED] wrote: Hi, We are working on a Flex-based website.

[flexcoders] Re: FlashPaperLoader.mxml - contentPath property
FlashPaperLoader is not an out-of-the-box Flex Component. Where did
you get it, from the Macromedia site? You imply that it is an MXML
file so it must be an example somewhere. I'll bet Manish thinks
you're talking about mx:Loader.
My guess is that it only has a contentPath variable and isn't written
to support run-time changes. However if you have the source, it
should be easy enough to do. Basically the contentPath property
needs to be a getter/setter pair so that the rest of the code can
receive notification of a change to that property's value and
execute another load sequence.

A Tree consists of TreeRows and cell renderers. The TreeRow places the open/close icon and the icon for the row and then its cellRenderer. If a Checkbox is the cell renderer then you'll get see the open/close then the folder/leaf icon then the checkbox then the checkbox label. Have you considered just replacing the folder/leaf icon with a checkbox icon and writing code to handle it being clicked?

[flexcoders] Re: Flash V2 Components and Flex Compatibility
You'll probably have to provide more details about how the List is being used, but in general, we don't promise that Flash V2 modules drop into Flex. One of the main issues is that Flex is entirely dynamic. It instantiates all of the components on-the-fly. In Flash one can easily place components on the stage or in other symbols. If you did that, it probably won't run in Flex as that is non-dynamic and the instantiation sequence in that case is not supported in Flex. Now, if you haven't done that, that implies that your app is pretty muc script-driven, in which case the best option is probably just to copy the script into .as files and compile them from MXML. --- In flexcoders@yahoogroups.com, Dennis Baldwin [EMAIL PROTECTED] wrote: We're in the process of porting some of our existing RIA functionality from Flash to Flex.

I originally had this as a repeater and it worked great, but now I
need it as 2 columns of data and thus the TileList is a good
solution.
Here is the code:
mx:TileList id=groupList cellRenderer=selectableGroupList
dataProvider={myGroups} width=100%
height={distributionTab.height*.20} itemWidth=350
itemHeight=20
columnCount=2/
CellRenderer Code:
?xml version=1.0 encoding=utf-8?
mx:VBox xmlns:mx=http://www.macromedia.com/2003/mxml; width=100%
height=100%
mx:Script
![CDATA[
var singleGroup:Object;
]]
/mx:Script
mx:CheckBox id=groupID label={singleGroup.groupname} /
/mx:VBox
Here is a sampling of the Array of Objects that is the variable:
myGroups
[0] (object #3)
b_fname: Jeremy
b_lname: Bruck
g_buyercid: 18946
groupname: Bearing Cage Coders

[flexcoders] Re: Memory Useage with Flex
Start commenting out portions of the app and see if you find a subsection that is sucking up the memory. Make sure you've optimized the number of layout containers used. Should you be using a Grid instead of a network of VBox/HBox? Are you using Repeaters? They can be memory hungry. Consider Lists with custom cell renderers instead. Is your app resizable? If not, and you're really desperate, take out the layout containers and use a single Canvas and your own layout logic.

Subject: [flexcoders] Contract between DataProvider and ComboBox
or
DataGrid
Hi,
I'm struggling to figure out the implied contract between
DataProviders and their users like ComboBox or DataGrid. When
either
a ComboBox or DataGrid first uses a DataProvider they seem to
make
numerous calls to:
public function get length():Number
and
function getItemAt(index : Number)
but it isn't obvious what the logic is behind these calls.
I was expecting to see a call to get the length followed by a
series
of calls to getItemAt starting at index 0 and running to index
length-
1, but that's not what I see.
Has anyone run across any good discussions of DataProviders and
their
users?
Thanks,
Randy

[flexcoders] Re: Tree dataProviders backingObject
Ah yes, the ol' convert arrays to children problem. The TreeDataProvider is guilty of trying to hard to figure out which parts of a complex object are children. I can only think of two ways to deal with this: 1) write your own implementation of TreeDataProvider that doesn't munge your data. 2) convert your data into the TreeNodes by using addTreeNodeAt then adding the arrays later.

if (cellEditor.hitTest(pt.x, pt.y))

// if comboheight 30, then dropdown is visible
if (cellEditor.combo.height 30
cellEditor.combo.dropdown._visible
cellEditor.combo.dropdown.hitTest(pt.x, pt.y))
return;
}
super.onMouseDown();
}
The the cell renderer watches for the close event on the combobox and
destroys its dropdown.
function close() {
size();
combo.dropdown.removeMovieClip();
combo.mask.removeMovieClip();
}

[flexcoders] Re: Tree change event
Yeah, looks like a bug. Don't see any obvious workarounds either. One questions: Do you even want to allow de-selecting a row? It might be possible to block that by overriding the onPress handlers in the SelectableRows in the Tree. Yahoo!

[flexcoders] Re: Panel Mouse Down Problem
There are some idiosyncracies when objects appear and disappear under
the mouse. In general, by listening to all mouse events (down, up,
over, out) you can see a pattern that you can look for (you may see an
over instead of a down for example).
In other situations, this can be remedied by not changing the object
under the mouse in response to a mouse event, which can be done by
taking the functionality in the mouse event, wrapping it in a function
and calling it via doLater.
function showAlertLater()
{
Alert.show(...)
}
mousedown=doLater(this, 'showAlertLater')
No guarantees, but we've worked around these kinds of issues
successfully.

[flexcoders] Re: Disabling individual list items
Unfortunately, there's no built-in API for disabling a row. There's no official API to get at individual rows either. You could set an enabled property on a row using setPropertiesAt, then have a custom cellRenderer look for it and disable itself. Yahoo!

[flexcoders] Re: Serious corruption in Flex-generated SWF
In the original post, I see that things are collapsing horizontally, and in two of the three pictures I see a horizontal divider. My guess is that there is a timing issue where the width of the divided box comes up 0 at the time of the layout, then pops back to the right size later, but does not layout the children again. I'd be adding some trace statements to the app to see if that's true. If there's an effect controlling the divider that can contribute to the problem. You might need to delay component instantiation until the effect ends. Could you be seeing something similar? To stick in trace statements, you can listen for move and resize events on various components and examine the parent and grandparent width and height values. Yahoo!

[flexcoders] Re: Image not being resized in mx:Image tag
Smells like a timing issue. What are you loading? JPG? SWF? I think you've replaced the example on your site with another thread's example so I couldn't see what you're talking about. If you load SWFs there is a timing issue where, once the SWF is loaded, we wait one frame and then ask the SWF for its size (_width/_height) then use that to calculate the stretch. If the SWF is multi-frame or code-driven, it can finish its rendering and alter its size after we took the snapshot of its size and then it won't look right. Manish proposes the right code, but you probably have to come up with a more sophisticated way to find out the true size of the SWF and run the Manish's fix at a later time. Yahoo!

[flexcoders] Re: cell render problem
The main reason is isn't working is an issue of types. You are setting the dataProvider to an array of XMLNodes. So, go back and set the dataProvider on the result of the webservice, then let's get the cells to display the right thing. You have proven that it works if you set the dataProvider to an array of strings. However an array of XMLNodes does not have properties on it like label. Instead it is attributes.label. So you have to use labelFunction instead, or a custom cell renderer that picks apart the XMLNode and find the attributes.label. Yahoo!

[flexcoders] Re: Custom Component Help
I could be wrong, but I think you are trying to specify data for a
component in xml. The only way I know to do this is to specify a
property of type XML then assign it and pick it apart. Here's a mini-
example:
Test.MXML
alexButton
xmlData
mx:XML
node name=Barney /
/mx:XML
/xmlData
/alexButton
alexButton.as
class alexButton extends Button
{
function init()
{
super.init();
label = foo;
}
var __data:XML;
function get xmlData():XML
{
return __data;
}
function set xmlData(data:XML)
{
__data = data;
invalidateProperties();
}
function commitProperties()
{
if (__data)
{
trace(setting label for + this + +
__data.firstChild.nodeName);
label = __data.firstChild.attributes.name;
}
}
}
In theory you could drop your entire XML structure where my node
name=Barney is and then write more code in commitProperties to
initialize the component.

[flexcoders] Re: DataGrid.labelFunction
The DataGrid has a labelFunction property that it inherits from its base classes, but it does not use it. Instead each column has a labelFunction property that you want to set. Yahoo!

[flexcoders] Re: combobox selectedIndex
The code snippet worked fine for me if the intervals property is an array of strings. Is it possible you are initializing intervals from a web service call? If so, you have a timing problem in that the selected index was set long before the data arrived (actually it thought it had zero rows of data). In such a case you should reset the selected index when the data arrives. Yahoo!
