Hi,
Any tips on how to make a smooth preloader on Flex for an SWF, without
the big jumps. Or instead is there a away to check if a SWF is already
in cache?
i'm trying to use this, but the problem is that when the ProgressEvent
stops the animation is not complete:
percent -= (percent-((evt.bytesLoaded/evt.bytesTotal)*100))*.25;
if (percent 99)
{
fpProgressBarMC.bar.width = Math.round (761 * percent / 100);
}
else
{
fpProgressBarMC.bar.width = 761;
completeTimer.start(); //animOUT but wait on complete

Re: [flexcoders] Viewstack showEffect and hideEffect playing at the same time
That's right. I couldn't remember what the documentation said. I had to
create my own viewstack component because I wanted to insert a resize effect
in between the show and hide effects.

Re: [flexcoders] Viewstack showEffect and hideEffect playing at the same time
I don't think you can. I've had to write my own viewstack-like component in
the past to achieve a series of animation effects. In my case it was a fade
out, resize, fade in.
You might have to write your own component as well if you can't live with
the effects that you come up with using a regular ViewStack.

Re: [flexcoders] Compile CSS to SWF problem

Re: [flexcoders] dragProxy as image dosen't show image
Instead of loading the image for a second time you could just copy the raw bitmap data of the loaded image using something like this: http://www.flex2components.com/f2cblog/2006/05/18/flex2-dnd-bitmap-copy/ I follow this approach when creating drag proxies in order to get a copy of the item being dragged.

Re: [flexcoders] Re: What is the correct way to detect activation of a Canvas in a ViewStack?
If you need to run this code each time your view gains focus as you put
it, then I think using the show event is fine because that should be
triggered each time the viewstack sets a new child to be visible. If this
code really only needs to run once, why don't you have your component just
listen to its own creationComplete or initialize event?
view:MyComponent initialize=handleInit()
mx:Script
private function handleInit():void
{
}
/mx:Script
/view:MyComponent

Re: [flexcoders] Re: What is the correct way to detect activation of a Canvas in a ViewStack?
Ok, I wouldn't feel wrong about this approach. We use a similar approach
within an application at work where a custom viewstack is setting one of its
children to visible, thereby causing the show event to fire. We rely on
this to trigger some code that sets up the view properly based on changes
that might have happened when the view was hidden.

On 3/26/07, wdsnapper [EMAIL PROTECTED] wrote:
It does need to be run each time this Canvas gains focus. The short
explanation is, one canvas has merchandise items available for sale.
An item is marked as in cart when it is added do prevent a user from
adding an item multiple times that is only allowed to be in the cart
once. The cart lives on another Canvas in the stack. A user could
choose to remove an item from the cart and then select that
merchandise Canvas again and the button needs to be reactivated and
have its label and style changed.
Therefore the only way I knew to make this happen within the Flex
model is to use a show event that triggered and caused the Canvas to
update itself.

Re: [flexcoders] Repeater Refresh
You need to use something like ArrayCollection which dispatches events. Your
repeater should then pick up the changes and add the new item.

On 3/24/07, Jeffry Houser [EMAIL PROTECTED] wrote:
I've done this with an ArrayCollections, but never with an Array. The
code would be something like this:

public function addItem():void{
myArrayCollection.addItem('test4');
}

/mx:Script
mx:VBox
mx:Repeater id=rp dataProvider={myArrayCollection}
mx:TextInput id=myRepeat /
/mx:Repeater
mx:Button label=click me click=addItem(); /
/mx:VBox
A few caveats...
a) I didn't test this code
b) In my situation, I wasn't adding from the same component that was
displaying things, so the 'add' and 'display were never shown at the same
time. There could have been other code that made the refresh work, but I
don't remember anything explicit.
c) When accessing a repeater element you use currentIndex when it is
repeating, but repeaterIndex after the fact. I haven't found a simple way
to switch between the two of them, but my solution was something like this:
try{
return myArrayCollection.getItemAt(loop.currentIndex );
}
catch (e:Error){
return myArrayCollection.getItemAt(loop.repeaterIndex );
}
I imagine there must be a better way
