[flexcoders] When $height != height...
I've got a component called ItemContainer that extends UIComponent. Inside it has a TextArea. I want ItemContainer's height and width to update to match the height and width of the TextArea when the TextArea's are changed (I've got a resizer class that lets you drag a widget to change the width/height of the TextArea). What's happening is that the .width and .height of the ItemContainer are being set properly, but when I do a getBounds on that same ItemContainer the $height and $width from mx_internal are different. They are the same values as the previous time they were committed. I am not well versed in overriding updateDisplayList or commitProperties, so I'm wondering what order I need to do things in to make the internal $height and $width the same (ie, valid). This is also not an intra-frame ordering issue... the difference between $height and height persists until I manipulate it again which can be any number of frames later. Any thoughts on this would be great. -b
[flexcoders] Disappearing content/Platform Differences...
I have been developing on an XP SP2 box and a Macbook, bouncing back and forth. Tonight I started having a problem where a remoting call was throwing an error on the PC but the Mac was fine. So I decided to grab my wife's laptop and see how the app did on hers. I was shocked and saddened to see that some functionality that works fine on the other two machines goes bad on hers. Specifically, content that I do a startDrag() on seemed to disappear. I have no idea what is going on, but in order to sleep tonight, I wanted to ask... a) Is this common in Flash land? I picked this platform because I thought I'd be able to avoid this. b) When you run into cases like this, what do you do? First thing that came to mind was to do a remote debugging session off of her computer. FWIW, her machine is a Dell Inspiron 640m. I tried updating the Intel gfx drivers, but no luck. Any insight would be great.
[flexcoders] Resize Effect Plays Twice?
Here is a really simple example that is bringing up some buggy behavior. This little app will let the user flip between a few different "trays". There is a resizeEffect on the ViewStack that holds the trays and a show and hide effect slides them. The resizeEffect is making the move effects play twice for some reason. If you disable it the tray move effects play just fine. Has anyone found a workaround for this? http://www.adobe.com/2006/mxml"; layout="absolute" backgroundGradientAlphas="[1.0, 1.0]" backgroundGradientColors="[#ADA4A4, #ADA4A4]">

[flexcoders] Debugging who changed data...
I have a property that is getting changed and I'm having a really hard time figuring out where it's happening and who is doing it. The debugger is walking me pretty far into the SDK and events are firing off and ultimately it's hard to tell. Anyone have any tricks for this?
[flexcoders] htmlText resets formatting... why?
I'm having an issue that maybe someone has run into before. I've made a simple rich text editor which edits a "model" that has an htmlText property as a string. The model is bound to a textArea and the "editor" which sets the properties of a textRange derived from the selection on the textArea. The editor provides formatting controls but no typing area, and the textArea is just for typing text. So the binding looks like this Editor <-> Model <-> TextArea Anyway, what I'm seeing is that the first time I create some formatted htmlText, it all sets properly through the chain. The bug is where I then simply add or remove letters without changing any formatting. That causes all formatting to reset. However, if I alter the formatting in any way, it propagates through alright and all formatting is preserved. Seems like some flag is being set when formatting is changed, yet that flag is not set when it's just a text change. Does this ring a bell for anyone?
[flexcoders] Re: htmlText resets formatting... why?
So, to follow up with myself... I ended up fixing this by unhooking bidirectional binding and instead use a regular Event.CHANGE listener on the textArea. There was some wack binding that was getting fired off right around where UITextField's validateNow() method was getting called. Unhooking the bind and only having the textArea update the model when it is typed in made it work properly. --- In flexcoders@yahoogroups.com, "bithroop" <[EMAIL PROTECTED]> wrote: > > I'm having an issue that maybe someone has run into before. > > I've made a simple rich text editor which edits a "model" that has an > htmlText property as a string.

[flexcoders] Events and Non-Display Objects
General question here... I understand Event flow with objects in the display list. They flow either up (bubbling) or down (capture) between parent and child. Maybe an oversimplification but my question really is about how to handle events with objects that are not in the display list. How do you pass events from them? Like for instance, I've got this situation here... I have an MXML that is just an . It's MXML because I'm defining some remoteObjects in it and that's just way more fun to do in MXML than in AS. So anyway, regardless, the methods inside are static and I don't want to draw the thing. It just needs to hang out and be available so I can make these remoting calls. So there's the rub. How can this MXML talk back to where it was called from? Can I use events for this or do I need to send a callback function? Any wisdom here would be awesome... this has been befuddling me for a while. -b
[flexcoders] Re: Events and Non-Display Objects
Thanks for the responses so far. I need to clarify what I'm asking I think. I realized after I wrote my post that since I had extended mx:object with MXML that I wouldn't be able to dispatch events from it. That really wasn't my issue though. Let's back up and say that I had extended EventDispatcher, or for that matter, something that _could_ be a display object but isn't in the display list, like mx:Canvas. What I'm really wondering is who can hear events dispatched from instances that aren't in the display list (have been instantiated but not addChild'd). Can any object at all? Can I direct who can hear them? My impression is that if an instance is not in a display list then it is effectively deaf and mute as far as events are concerned. This seems wrong, but I don't know how else it should work. --- In flexcoders@yahoogroups.com, Jehanzeb Musani <[EMAIL PROTECTED]> wrote: > > You can adopt the following two options to achieve > your requirements. > > 1.

[flexcoders] Re: Events and Non-Display Objects
Jehanzeb - first, thank you for the detailed response! I really appreciate it. In the code you provided, the CustomEventDispatcher was instantiated within the mx:Application object. So from what I've seen, yes Application will be able to hear CustomEventDispatcher's events. However, my sitation is more like: Application | |-->ContainerC->ContainerD | |-->ContainerA->Custom AS class not in display list->CustomEventDispatcher. And I want CustomEventDispatcher's event to be heard by Container D. Right now I have my listener on Application, and then Application is calling a method on ContainerC, which is then calling a method on ContainerD. This seems to be ugly and bad form. So instead, will this work? (see below pseudocode) --- inside ContainerD addEventListener("testEvent", someHandler, true) //is capture needed? inside CustomEventDispatcher dispatchEvent(new Event("testEvent")) //is bubbling needed?

[flexcoders] Styling extended Flex Components... simple misunderstanding?
I think I'm not understanding something... My app has a bunch of .mxml classes that extend TitleWindow (singletons in a UI). I want them all to be styled the same EXCEPT for I want each one to have a custom background color. Here's how I'm attempting this... -begin external css file--- TitleWindow { borderAlpha: 0.9; borderThicknessLeft: 4; borderThicknessTop: 0; borderThicknessBottom: 16; borderThicknessRight: 4; roundedBottomCorners: false; headerHeight: 20; backgroundAlpha: 0.33; highlightAlphas: 0.29, 0.02; headerColors: #ff, #cc; footerColors: #e7e7e7, #c7c7c7; dropShadowEnabled: true; backgroundColor: #ff; } ExtendedTitleWindowA { backgroundColor: #ff; } ExtendedTitleWindowB { backgroundColor: #00ff00; } -end external css file--- So... this doesn't work. What is happening is that everything that extends TitleWindow looks the same and the custom backgroundColors are not taking. The css is linked via the top level application. Can someone set me straight? -b

[flexcoders] How can I overlay a UIComponent on top of my application?
Trying to figure out the best way to do this... I have an image in my UI which is small. I want a larger version of it to draw, attached to the mouse cursor, when the user rolls over it. Kinda like a tooltip but moving along with the cursor. (Mixbook does this if you've ever seen it) I have it mostly working but my main issue is that I know I always want the zoomed version of the image to draw on top of the entire UI. These small images can be in any number of different types of containers, so I can't addChild the UIComponent to the small image or to its parent... needs to be something like a popup or tooltip. Peeked a bit at SystemManager for this since that's what PopupManager talks about... anyway, anyone have any insight on this? Should I make it a cursor?
[flexcoders] Re: How can I overlay a UIComponent on top of my application?
Heh, well funny part Tracy is that in looking at my app, I have a ViewStack that is the child of the app, and it is what is driving the horizontal layout. The app is set to horizontal, but it is doing nothing (except for eating cycles "laying out" its one container). Anyway, I set the app to absolute, put the overlayed component to Application.application, and it's all good.

[flexcoders] Component rendering inconsistency once placed...
Are there any common issues to look for when facing this situation: I've made a new mxml component that is an arrangement of standard UI elements inside a Panel container. The panel renders fine on its own, but once it's placed inside another component or app, the layout goes bad. I've cleared all explicit widths and heights as far as I can tell, but I'm having trouble with this one. Any ideas? -b
[flexcoders] Re: Drag and Drop Problem
I did something similar, but I took an element of one type from a list and dropped it onto a canvas and then converted it to another type. This was done by just accepting the data type that gets dropped in the doDragDrop function and converting it in there before adding it. The odd thing is how it's in the "items" list. I believe that hung me up for a while. Anyway, check out the code, which I think is pretty much a rip from the docs. This code is from my receiving canvas. private function doDragEnter(event:DragEvent):void { var dropTarget:Canvas = event.currentTarget as Canvas DragManager.acceptDragDrop(dropTarget); } private function doDragDrop(event:DragEvent):void { var dropTarget:Canvas = Canvas(event.currentTarget); var items:Array = event.dragSource.dataForFormat("items") as Array; if (!(event.dragSource.hasFormat("items"))) { trace("stop"); } for (var i:int = 0; i wrote: > > I am running into problems using drag and drop in Flex.
