[flexcoders] Re: Should I follow this recommendation when it comes to Flex learning curve?
That recommendation has some merit, but the use of Flex in no way depends on HTML, PHP, or CSS (though it helps). Flex is a front-end GUI builder, since it uses actionScript it would be helpful to have some background in other ecmaScript languages (like javaScript), but it isn't required. Flex is limited in being able to connect to Databases and does require a little knowledge of php and sql (or whatever your back-end language is) in order to get and store data. I develop in Flex and php, I never used php before October, but it was simple to learn enough to connect my Flex app to a database. I guess what I'm saying is that your friend is neither right or wrong. It really depends on you. Did you learn to swim by starting in the shallow end and working your way into the deep? Or did you jump right into the lake? --- In flexcoders@yahoogroups.com, fred44455 fred44...@... wrote: I already know some html and CSS .

I'm a little curious why you're jumping straight into advanced stuff and skipping the basics completely. Start with HTML and CSS. Those are literally the building blocks of the web. If you don't know them, it doesn't really matter if you understand OOP, because you'll never be able to format the output for the web. Then I'd move on to something like PHP... get a good solid grounding in basic programming logic used on the web. THEN jump into ActionScript/Flash programming and Flex.

[flexcoders] Re: XMLListCollection Filter - Viewing a single child branch
The Flex framework has awesome XML functions, even straight up querying of XML.
I use this all the time: var myXML:XML = XMLVar.node.node.(@nodeID == 5) which
will give you just this section of your XML
node nodeId=5
node nodeId=6
node nodeId=7/
node nodeId=8/
node nodeId=9/
/node
/node
I'm not sure if this solves your problem exactly, but its pretty powerful stuff.

I'm glad I got to this before anyone spent their precious time on it.
Unfortunately, the problem was not with my code but stemmed from my
fundamental understanding (or misunderstanding) of an XMLListCollection.
Turns out XMLListCollections aren't magical gateways into hierarchal
data. As far as I can tell, they are essentially flat structures that
hold a reference to a list. I'll explain my failed attempt and hope
that it will help somebody avoid the same mistake. Here's roughly what
my data looks like:
node nodeId=1node nodeId=2node nodeId=3/node
nodeId=4/node nodeId=5node nodeId=6node nodeId=7/node
nodeId=8/node nodeId=9//nodenode
nodeId=10//node/node/node
I was trying to apply the following filter function on the
XMLListCollection to view a single child branch:
public function viewBranch(xmlItem:XML):Boolean {return
xmlItem.descendants()@nodeid == selectedNodeId; // where selectedNodeId
corresponds to the appropriate nodeId }
The problem with this is there is only one object in the
XMLListCollection and it is either filtered out or it is not. Since
the single list contains all values for nodeid, any proper value for
selectedNodeId will result in the entire list being included in the
view. Ah well, live and learn.
I've since moved away from XMLLists, but if anyone has an idea of how to
perform the original task with XMLListCollections I'd love to hear it.
Cheers,

Howdy everyone,
I'm struggling with an XMLListCollection filter function. My xml is
similarly structured to this:
node

node/

node
node/
node/
/node
node
It consists of a root node, with zero or more child nodes. The child
nodes could also have zero or more child nodes. Basically it's your run
of the mill xml. =P
I'm looking for a filter function which allows me to view a single
child branch. In other words filter out all but a particular child node
and it's children. Effectively it would turn the view into this:
node
node/
node/
/node
The goal is to keep the original xml unaltered, while creating a view
of a child node that appears to be the root. The view will then be
applied to several components. Although I've struggled with with it, a
filter seems like the simplest way to go. I'd greatly appreciate any
suggestions.

[flexcoders] How can I automatically scroll a VBox when an item is drug near the top or bot?
I have a VBox containing a bunch of panels. I have implemented dragging and
dropping but I need to be able to scroll automatically when the item is drug
near the edge. I am having mixed results. I can get it to work, but not well.
My example is below. It works if the user bounces their mouse around a little
near the top or bottom edge, but I want it to work if they just hold the mouse
there. Any suggestions?
On Mouse down (I'm doing several other things but this is one of them):
VBox(di.parent).addEventListener(MouseEvent.MOUSE_MOVE,autoScrollSection,true,500);
On dragDrop
VBox(evt.currentTarget.parent).removeEventListener(MouseEvent.MOUSE_MOVE,
autoScrollSection,true);
Here is the autoScroll function:
private function autoScrollSection(evt:MouseEvent):void{
var tempVBox:VBox = VBox(evt.currentTarget);
if(tempVBox.mouseY50){
tempVBox.verticalScrollPosition += -50;
}
if(tempVBox.mouseY int(tempVBox.height-50)){
tempVBox.verticalScrollPosition += +50;
}
}
So if they are within 50px of an edge then it should scroll by 50px. I've
exaggerated the numbers just to get an affect.
[flexcoders] Re: How can I automatically scroll a VBox when an item is drug near the top or bot?
Heres how I solved it:
[Bindable] public var timer:Timer = new Timer(50);
private function autoScrollSection(active:Boolean,cont:VBox):void{
if(active){
timer.addEventListener(TimerEvent.TIMER,function():void{
if(cont.mouseY50){
cont.verticalScrollPosition += -20;
}
if(cont.mouseY int(cont.height-50)){
cont.verticalScrollPosition += +20;
}
})
timer.start();
}else{
timer.stop();
}
}
Then changed the calls in mouse down and drag drop to this respectively
autoScrollSection(true,VBox(di.parent));
autoScrollSection(false,VBox(evt.currentTarget.parent));
It works, but feels like a bit of a hack. I welcome any better suggestions.

Our application works ok, but sometimes the CPU skyrockets suddenly, we
see the jsvc process uses 100% CPU and our Livecycle server hangs..
When the livecycle server hangs, the debug logs start showing the
following messages over and over again.
Apperently there is a deadlock or infinite loop... what could be the
cause of this ? What exactly does this message mean ?
Thanks for your help !

I don't have time to look it up right now, but I'm pretty sure you catch the Tab key down, then check if the shift key was down at the same time.

[flexcoders] Drag and drop, custom cursor during drag not working
I have a datagrid that I want the user to sort the rows on. To make it obvious
that it's sortable I am implementing some custom cursors. But I'm having a
problem when I actually drag an item. Can anyone help me out?
Thanks
here's a psuedo demonstration of the problem
Application = normal cursor // fine
Rollover datagrid = open hand cursor // good so far
mousedown on datagrid = closed hand cursor // good
dragging item around = closed hand cursor // switches back to normal cursor (if
I move it around real fast I can see my custom curser for an instant)
mouse up on datadrid = open hand cursor // not sure, after I drop it goes back
to open hand but if I mouse down, dont move and mouse up I have a closed hand
rollout of datagrid = normal cursor //good
datagrid code:
mx:DataGrid id=sectQuestionsDG x=10 y=204 width=558 height=277
headerHeight=0 selectable={editMode}
dragMoveEnabled={editMode} dragEnabled={editMode} dropEnabled={editMode}
dragDrop=sectQuestReOrder(event); rollOver=over(); mouseDown=down();
mouseUp=up(); rollOut=out();/
functions:
public function over():void{
CursorManager.setCursor(grabCursor,CursorManagerPriority.LOW,0,0);
}
public function down():void{
CursorManager.setCursor(grabbingCursor,CursorManagerPriority.HIGH,0,0);
}
public function up():void{
CursorManager.setCursor(grabCursor,CursorManagerPriority.LOW,0,0);
}
public function out():void{
CursorManager.removeAllCursors();
}
[flexcoders] Re: Drag and drop, custom cursor during drag not working
OK, That helped a little bit, I'm now doing this on rollOver var styleSheet:CSSStyleDeclaration = StyleManager.getStyleDeclaration(DragManager); styleSheet.setStyle(moveCursor, grabbingCursor); CursorManager.setCursor(grabCursor,CursorManagerPriority.LOW); This is giving me the correct rollover and correct drag, but if I try to add any function to rollOut it screws up again, so now I'm stuck with the grabCursor. It seems like when I set a rollOut on the dataGrid it's firing for each row, same with mouseOut, is there any way to avoid that? ~Thanks --- In flexcoders@yahoogroups.com, Chris zomgfore...@... wrote: Just a thought, as I haven't tried the method you described. What about setting the styles of the cursor on mouse down? var styleSheet:CSSStyleDeclaration = StyleManager.getStyleDeclaration(DragManager); styleSheet.setStyle(moveCursor, grabCursor); or styleSheet.setStyle(copyCursor, grabCursor); And you could set it back on mouse up. Just a thought because maybe DragManager is setting things back to what it has set in its styles.

[flexcoders] Re: Prevent inset/shifting of text in selected tabs
I couldn't even notice it before, but now I can see it shifting about a pixel. It looks to me like it defaults to being vertically aligned to center, and the selected tab has no bottom border, so the space to center the text in is slightly bigger. There is no vertical-align style for selected tab or any tabs for that matter. Maybe an itemRenderer is the solution.

Amy, I know I answered you privately when the group was down, but I wanted to throw the answer in here in case anyone was searching for it: When I came across this problem I found that it was a known bug.

[flexcoders] Re: Flex Builder 3 - Crashes
Had this prob with another program, it was a major software conflict, something like a windows BSOD so bad that it couldn't even do a BSOD. Tracing this problem is a nearly impossible task for a normal user. It could be a conflict with almost any installed software, my issue only occurred when I had MS Office IEX (the crashing app) installed, then it only occurred when I resized a window by clicking and dragging the lower right corner, not a side, top, bottom, or any other corner. Re-installing is not going to help because the conflicting software is still installed. What may make the difference is where the conflict is occurring so try closing the app in different ways. Assuming you're using windows, try clicking the [X], file-close, right clicking and selecting close from the start bar, and even using the task manager.

So I am going to assume you are using a loop, and lastLabel is a variable set to the last label created in the loop. You're code's going to break on the first iteration since it can't divide a null value by 2. You need to either set an initial value for lastLabel before the loop or not process that line on the first iteration, instead setting the position. That is probably what you really want to do since you would want your first label to be at a fixed position and the second to base it off of that.

apply sortfields to an AC) and then you apply that new sort to your AC.

RE: [flexcoders] [SPAM] Re: Passing an object to a rendererProvider
My understanding of it all is pretty negligible. I found an example similar
to what I wanted to do online, then modified it just a little to make it
work. My problem was I needed the Summary rows to display text
(templateType), but I also needed them to sort based on a different field
(templateTypeID). I couldn't figure out how to tell it to sort on one, but
display the other. My little hack works, but if I could somehow send the
text to the renderer along with the int, or still have it sort on the int
and only send the text I would at least feel like I'm doing it the right way
instead of duct-taping it.

[flexcoders] Passing an object to a rendererProvider
So I need to pass additional information (an object like an associative array) to my renderer provider which is stored nicely in a component, but I can't access any variables in my parent application from the component, only children. As a work around, I parsed the object variable to text, put it in an invisible mx:Text control, and parsed it back into an object in my component. I feel like a hack because I know this is horribly inefficient and there has to be a better way, but I couldn't come up with one. Thoughts anyone? ~Mike PS, I did this because I'm using a summary row in an advancedDataGrid to divide it into sections, but I don't want to sort by the lable of each section (which seems to be the default) but by an ID. My solution was to pass it the ID which will sort it correctly then pull the correct lable text out of my object with that ID. It works perfectly like it is but does anyone know the Right way to do this? -- View this message in context: http://old.nabble.com/Passing-an-object-to-a-rendererProvider-tp26396466p26396466.html Sent from the FlexCoders mailing list archive at Nabble.com.

Re: [flexcoders] Problem sorting advancedDataGrid after dataprovider updated
My app isn't crashing at this point, maybe it's a difference of which SDK we are running, or more likely some specific issue of environment, but when I click another tab it runs the HTTPService and repopulates the Grid. It's only after that repopulation that I loose the ability to sort the data. Thanks for looking into it though. valdhor-3 wrote: It looks like you have a bug. When I click on the Enterprise Library tab, the HTTPService is invoked and the data is returned. Then inside your getTemplates_result function it crashes with a null object reference when you try to do gc.refresh(). I would check why the app crashes here (I don't have time to debug your code). -- View this message in context: http://old.nabble.com/Problem-sorting-advancedDataGrid-after-dataprovider-updated-tp26326531p26378551.html Sent from the FlexCoders mailing list archive at Nabble.com.
Re: [flexcoders] Problem sorting advancedDataGrid after dataprovider updated
Ok, we are running the same SDK. Lets try to explore what you are identifying. Please forgive me as I am pretty new to FLEX and AS. gc is the id of a GroupingCollection of a dataProvider. refresh() is a built-in public method to GroupingCollections. How can that be a problem unless it's a bug in the FLEX SDK itself? Further more, it runs fine on the initial call that populates the data the first time. It's the exact same function running with different data when the tab is clicked, why would it not cause a problem the first time but does all subsequent times? I'm not doubting that this may be the problem, but if it is, I have no Idea where to start to fix it. Thanks again. valdhor-3 wrote: I am running SDK 3.4. I still believe that is the crux of the problem. You can't sort because the gc.refresh() is not working properly. -- View this message in context: http://old.nabble.com/Problem-sorting-advancedDataGrid-after-dataprovider-updated-tp26326531p26379293.html Sent from the FlexCoders mailing list archive at Nabble.com.
Re: [flexcoders] Problem sorting advancedDataGrid after dataprovider updated
If I remove the whole mx:dataProvider tag and add the dataProvider
attribute to the mx:advancedDataGrid tag with the value of
{xmllTemplates} then I can sort, change tabs and am still able to sort, so
It does seem to be something about the groupingCollection.
I have no idea how I would monitor the collectionEvent.CHANGE event. I tried
to google up some examples on it, but anything I could find was WAY over my
head. Is there some simple way to do this?
Thanks again for taking the time with me, I know you probably have better
things to be doing.

So, if you try it without the grouping collection, does it work?
Are you monitoring the collectionevent.CHANGE event? What happens when the
collection changes?

Re: [flexcoders] Problem sorting advancedDataGrid after dataprovider updated
Problem Solved... I guess. I was turning my HTTPService result into an XMLList. I just switched it to an arrayCollection and I no longer loose the ability to sort when I refresh the data. Maybe there is some limitation when using an XMLList, I wish I could have found out for sure, but at least I have a working product now. Lesson Learned: use arrayCollection, it's apparently a superior veriable type.

[flexcoders] Problem sorting advancedDataGrid after dataprovider updated
Anyone know about this?
My data comes in, and I can sort just fine, I refresh my dataProvider (pulls
a different query) and then I can't sort anymore, even if I go back and pull
the original data again. I have been searching and searching for a post on
correcting this issue but can't find one.
Here's the code, I hope someone can help me.

Re: [flexcoders] Flex Data Grid Question
Apologies for resurrecting a somewhat old thread, but since my searches
turned me up here and I spent several hours today working on this issue I
thought it would be appropriate.
Here's is the code I came up with that mostly solves this.
My source data is just a basic XMLListCollection.
The renderer colSpanningHeader is a basic label component. I did nothing
but make it align center

I find one problem with this, I can't completely get rid of the first
column. It makes my grid look a little tacky.
Anyone out there know how I can get this same method of grouping without
showing the first column? I don't want a folder tree, I just want a header
row for each group.
Thanks

Re: [flexcoders] Flex Data Grid Question
I'm not sure how to group in the way you're wishing it, but I am sure that it
can be done. I think the trick is with the item renderers. Which is
something I just learned about. Here's my entire code, Sorry I can't release
the entire http service since it's to a protected site, but it pulls back a
basic XML file formatted like so:
rows
row

otherother value/other
