From my main flex mxml, I am trying to detect the size of a rect:Rectangle that I created in my InfoBubble.as class. The info bubble itself is created in my InfoMap.as class. How can I access the attributes of the rectangle I created?
Here is the variable portion of the InfoBubble class:
Code:
public class InfoBubble extends Sprite
{
//public var textField:TextField;

I was working on some blitting code today and after profiling it found that I was creating 1000s of new rectangles. I was shocked because I only had 1 or 2 different new Rectangle() calls or I was using the .rect property of BitmapData.
I started commenting out huge swathes of code until I was left with this code in my sprite class:
canvas.bitmapData.copyPixels(_bitmapData, _bitmapData.rect, destination, null, null, true);
I cached the result of _bitmapData.rect at object creation and my thousand of new rectangle calls were suddenly gone from the profiler.
Why the heck would BitmapData.rect create a new rectangle? Is there a way to check the core libraries or something and confirm this is true?
i was trying to mess around with flash and I was hoping I would use TweenMax to scale up a rectangle (instantiated as rect) on mouse over, and then once it is scaled up I wanted to load an swf file to its center (the swf is called CircularPreloader.swf which is a fake preloader, just for messing around porpuse). Well, I tried but it didn't work cuz I kept getting this
error: TypeError: Error #1009: Cannot access a property or method of a null object reference.

Here's the code:
import gs.*;

I draw a rectangle within another rectangle like this (I use it as a mask):
CanvasBorder.graphics.beginFill(0xf0ff00,0.1);
CanvasBorder.graphics.drawRect(100,100,550, 300);
CanvasBorder.graphics.drawRect((stage.stageWidth/2-Canvas.width/2),(stage.stageHeight/2-Canvas.height/2),250, 150);
CanvasBorder.graphics.endFill();
effectively its a 550x300 box with a 250x150 cutout.
Within one of my functions I need to resize the INNER 'cut-out' box from 250x150 to 150x100 - but keep the OUTER box exactly the same.
Normally when I'd resize a normal rectangle I'd do this:
rectangle .width = 150;
rectangle .height = 100;
I've got a tricky one that's stumping me, could you take a quick look over it I draw a rectangle within another rectangle like this:
Code:
CanvasBorder.graphics.beginFill(0xf0ff00,0.1);
CanvasBorder.graphics.drawRect(100,100,550, 300);

I'm trying to create a custom button with ActionScript 3.0. I'm suing a round rect as background, but I have a problem with it size. This is my custom button class:
[Code]...
I don't know why when I use a size of (40, 20) I get a smaller rectangle than that size.
I have a problem with stage resize.I have a small rectangle on the right bottom of my stage. When I resize the stage, I want my rectangle keep its size (no scale) and position ( always on the right bottom of the stage). Here is my code:
mymc._width = 50
mymc._height = 20
Stage.scaleMode = "noScale";[code].......
I'm trying to change the size of a rectanlge when it is clicked. At the moment, the rectangle increases in size from both the top AND the bottom. I want to have it so that when it is clicked, only the top of the rectangle increases.
View 7 RepliesI'm creating a map that has points of interest. (POI) When a user mouses over the POI an info bubble pops onto the screen and it loads an swf. I can't detect the size of the swf so that my infobubble will size itself to the size of the swf. When I mouse over my swf file, it disappears.

I have a class called shapeC that only creates a rectangle and then addChild(rectangle);. That class is instantiated on the main timeline. Currently, the only way you can see that rectangle is to add the instantiated class to the stage via addChild(shapeC);. My question is, is there a way that the shapeC class can add the rectangle to the root stage without requireing the instantiated class to be added to the stage?

Is it possible to use scrollRect without the flash.geom.Rectangle class?I know the scrollRect can be used like this:import flash.geom.Rectangle; myMC.scrollRect = new Rectangle(10,10,100,100);I need to make a flash which doesn't extends outside the stage (bacause loading it from another flash will expose anything outside the stage area). Using a mask is an option, but scrollRect seems very interesting because it would be easier and give greater performance.But I can not import the flash.geom.Rectangle class (and it seems overkill to import a class just to set x,y,width and height)How can use scrollRect without the flash.geom.Rectangle class?

View 1 RepliesIs it possible in Flex 4's VideoPlayer control (spark.components.VideoPlayer) to detect some attributes of the source video?
In my case, it's a local file. I would need to detect the original width and height of the input source video (an h264 f4v).
I'm writing an application in AS3 on Flex that utilises USB removable storage - SD cards - and I need to display the space available on it in a progress bar.Getting the space available on a drive is straightforward enough using:
flash.filesystem.storageVolume.rootDirectory().spaceAvailable
but to display free space graphically, I need to know the total size of the drive and I can't find anyway of getting that info.For now, I've resorted to guessing the size roughly based on the free space, but this is obviously far from ideal.I've scoured the vast documentation that Adobe provides and googled 'til my fingers ache, but no luck. I'm guessing this may not be possible with the standard framework and may require a custom Native extention to be written.
I have a SWF that's 1100 x 730 (odd size, I know). What I want to do is detect the window size (not screen resolution). If the width of the window is less than 1100, scale the SWF to fit the window. If the width of the window is 1100 or higher, do nothing.

Tried stage.stageWidth and stageHeight on applicationComplete, but for some reason the actual numbers returned do not seem to be accurate - the image always appears off-centered (stageWidth/2 - imageWidth/2). How do you determine the mobile device's actual screen size, to center an object?

View 8 RepliesFor those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you.So I needed to get a Scrollbar, which I got hereThe thing is, it works with Sprites.After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have.
So I tried adding the TextFieldExtended instance to a Sprite instance using addchild.A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it.My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible?

The only thing is, I'd like the registration point to be in the middle (not the top left corner). Is there a way to set up the registration point in the middle of the rectangle, but still have the position of the rectangle be correct?
i.e. not moved over so that the top left corner of the rectangle is in the "middle" of where I want the rectangle to be...

When I use <s:Rect> to create a rectangle, I use radiusX to get rounded corners. Problem is all are the same roundedness. Is there something similar to Rect that lets me control the radius for each corner separately? If not, what's the best way to create this from scratch? graphics library or what?
View 3 RepliesI am trying to convert a rectangle(actually multiple rectangles) to a curved rectangle. I think it should be pretty easy but I guess i am stupid. Basically I would have a start position and stop position (many of these), and they would be converted to curved rectangles and follow in a cicrle around.
View 0 RepliesI would like to create a rectangle inside of a rectangle, starting approximately 15% inward from the right side of the other rectangle.
I know how to create rectangles with:
Code:

newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);
addChild(newHotRect);
But how would I make another rectangle on top of that (the black one pictured) that is approximately 15% from the right?
I toyed around with .right, and .bottomright with no success. Can anyone lead me in the right direction? or even finding the x and y of the upper right or bottom right side of a rectangle?
how to respond when a rectangle hits another rectangle? I already know how to detect the collision, I just don't know how to respond to it.
