[flexcoders] Drawing letters -- sprites?
I have a project where I am drawing circles and line and such directly onto a component extending a UIComponent (all actionscript) I've had problems finding examples of drawing letters (or font characters). The best I've been able to come up with is to use IUITextField objects and place those on the stage... but this is terrifically limited. Dynamically changing the font size and such becomes a really big issue. var textField:IUITextField; textField = IUITextField(createInFontContext(UITextField)); textField.text = _value.toString(); Are there any examples where I can draw the sprites for the letters themselves?
[flexcoders] horizontal rule background
I have written a pinstriped background class that extends HaloBorder. It
works great... (as the plainest example) basically I just overrode
updateDiplayList..
You basically end up with a rectangle with a light pinstripe effect.
Nice.
But what I want to do is follow any rounded corners that are being
drawn. I can draw a rounded rectangle (of course) but I don't know how
to clip my lines to the inner boundry of the rectangle. I am currently
drawing line after line for the full width in a loop after the backgound
is filled (see psudo-code below).
All you drawing experts... Is there a way to draw the portion of each
line which intersects with the already drawn rectangle?
the class looks similar to the following:
package {
import mx.skins.halo.HaloBorder;
public class HorizontalRuleBackground extends HaloBorder {
//
\
- //
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void {
super.updateDisplayList(unscaledWidth, unscaledHeight);
// At this point we cannot do rounded corners, so we need to
// flatten the rounded corners no matter what
topCornerRadius = 0;
bottomCornerRadius = 0;
var matrix:Matrix= verticalGradientMatrix(0, 0, unscaledWidth,
unscaledHeight);
var backgroundColor:uint = getStyle(backgroundColor) as uint;
graphics.beginGradientFill(linear, [backgroundColor, backgroundColor],
[1,1], [0,255], matrix);
GraphicsUtil.drawRoundRectComplex(graphics, backgroundLeft,
backgroundTop, backgroundWidth, backgroundHeight, topCornerRadius,
topCornerRadius, bottomCornerRadius, bottomCornerRadius);
graphics.endFill();
var stepSize:int = 3;
var numberOfLines:Number = unscaledHeight/ stepSize;
var borderColor:uint = getStyle(borderColor);
graphics.lineStyle(1, borderColor, .2, true);
for(var i:int=0; iunscaledHeight; i=i+stepSize) {
graphics.moveTo(0, i);
graphics.lineTo(unscaledWidth, i);
}
}
}
}
[flexcoders] removing component height
I have a thing I bump into from time to time and I know there justMUST be a solution for: Sometimes I want to leave a visual component on the screen but set its height to 0 explicitly, so that it takes up no space. Then later I want to say disregard my '0' and measure yourself. How do I (in essence) remove that explicit height setting and allow the component to set its own height? In action script I cannot seem to say component.height = null; component.invalidateDisplayList(); Anyone have a nice simple trick?

[flexcoders] AIR Window and Mouse management
Is there a class or object out there that I can get reference to the mouse no matter where it is? I can't seem to find anything. I have an AIR app with multiple native windows. I want to show things in those windows while the mouse is over them, but not show them when the mouse is elsewhere. I have implemented the normal mouseOver mouseOut stuff but it's very easy to get into a scenario where mouseOut doesn't get called (another non-air window overlapping the air window for example). So I think I need to implement some form of collision detection in reverse. I think running a timer once I show things in the window (with mouseOver) to test to make sure the mouse is still within the boundaries of said window. But I cannot seem to get reference to the mouse without an event. And as far I know events are not broadcast into AIR when they occur outside of AIR (as far as I have been able to replicate at least). Can someone steer me a bit here? I HAVE found the deactivate event on a native window. At least if the user clicks somewhere else then I can handle that...

Please forgive me if this topic have been brought up before, but

forward...
We have no trouble embedding TruType Fonts in our Flex app, but
OpenType Fonts does not compile. Is this simply the way it is -
no
support for OTF in Flex 2 or are we missing something?
For reference, we are using a .css file to embed the fonts. As a
syntax example, the following entry will compile fine
@font-face {
src:url(fonts/gara.ttf);
fontFamily: Garamond;
font-style: regular;
}
However, replacing the font with an OTF font like this
@font-face {
src:url(fonts/AGaramondPro-Regular.otf);
fontFamily: AGaramondPro;
font-style: regular;
}
throws a compiler error:
exception during transcoding: Unexpected exception encountered

reading font file '/U:/bnielsen/init/app/flex/fonts/AGaramondPro-
Regular.otf'
If anyone on the list can offer any advice, it would be much

[flexcoders] Update Progress Bar during processing
This seems like a simple thing, but I have a progress bar that works just fine. The problem is the loop I'm working through is taking all of the resources for the flash container while it works. Put another way: I am processing 1000 records It takes 45 seconds to complete and is invisible to the user While this loop of processing takes place I want to update a progress meter telling the user I'm still working but Since this loop is so intense the whole flash container hangs or apears to pause.

[flexcoders] Re: Can't deploy .swf
John, I'm not certain I can help you here but I can tell you what I know. Maybe something will be useful: source files: I use the Flex Builder environment, so this may not pertain to you: Upon build Flex creates a bin directory where all executable files are located. This is helpful in at least allowing you to FTP an entire directory to your server and not have to pick and choose. In there are the swf and html files you mentioned. I would assume the issue is some other resource in that directory is not being included in your Send to a friend. So, #1: entire bin directory As for #2 this is a tougher issue. Basically, you cannot call off server or into a higher security setting unless you are running the application through the flex builder or there is a crossdomain file on the server you are calling. To state this more clearly: If you put your program on http://www.mybox.com and within the program there are services trying to call any domain (URL) not in the www.mybox.com domain then you will hit the sandbox security problem. This (seemingly) also goes for running it from your own hard drive. Though I swear I have run things from my own machine that accessed everywhere else without it running from the Flex Builder environment, I have also seen it fail. So the last part of even on your own hard drive part is very suspect. The second part of the problem is calling from http into an https environment. That is the second security catch and you will need an extra line in your crossdomain file (secure=false I believe) to allow this kind of communication. Cross domain files are simple, but they have to be on the server you are gathering the data from which can be a problem for something like an RSS reader since you likely won't be reading your own feeds and thus you likely don't own the boxes. A simple way around this sandbox is to write a proxy program on your web server. It can be the program that calls the URL you want and simply returns the data to your flash player -- thereby never having to ask your flash program to talk outside of its own domain. I hope any of this helps. --- In flexcoders@yahoogroups.com, John Buono [EMAIL PROTECTED] wrote: This might sound to trivial, but it is frustrating. i have just gotten Flex 2.

I'm sure just getting the first idea of how this works will be enough. Thanks
[flexcoders] Re: User Authentication
You will, no doubt, get much better answers from others as I am working on the same things over here. But Flex plays in your browser's session management like anything else. In other words, it sends the same headers the browser would send when requesting something from the server. If you already have a logged in state on your website I'd say just host your flex application on a secured page. That will inherit the same authentication you use for everything else. If you want flex itself to be the application that does the user logging in -- i.e. having a login form in flex. Then you will have to build that in the application. As far as I can tell, the easiest way to force this log-in is to have a viewstack on your main page (application perhaps) that stops on the login form first, then switches the stack to the application after talking to the servers to verify the user's info. I know that's all over the place, but I hope something rings a bell for you. --- In flexcoders@yahoogroups.com, pioplacz [EMAIL PROTECTED] wrote: Hi!

That's all fine and good (though more than I want to do for 30 columns
really.
First, can I set something that takes the padding off of the cells?
If not, can I abstract the itemRenderer above into a new component that
is virtual? I'm having troubles with the theValue you see above. If I
just put out data in an abstracted component it does not peer into the
object for the dataField=theValue as defined in the line as:
mx:DataGridColumn dataField=theValue
itemRenderer=renderers.DataGridCellTiny/
All that comes out of that is [Object], so short of creating an
abstracted component per column I don't see how to pass the itemRenderer
any references to tell it what field to get out of the object.
Wow, that was much simpler in my head.
[flexcoders] Array Inefficiencies??
I sure as heck hope someone out there has an answer for me on this
one...
Has anyone else seen inefficiencies with arrays?
I have a file with 1000 rows that looks
this,that,other,etc,etc
again,this,is,another,row
I load that into an Array called values splitting on ,. That all
works fine. The array builds happily and quickly. But when I populate an
object from that array (see below) it's slow as Christmas.
Here is an example of what I am doing:
if(false) {
// 1000 @ 2 seconds : 50k Rows in 1 min 40 sec
val1 = new String(123456);
val2 = new String(12/12/2005);
val3 = new String(12/13/2005);
val4 = new String(asdfjklmsd mjnklsdf);
val5 = new String(asdfjklal alamjnklsdf);
val6 = new String(aasd9asdf;lj asdf);
val7 = new String(aaa2a6236523);
val8 = new String(IP);
} else if(true) {
// 1000 @ 8 seconds : 50k Rows in 6 min 20 sec
val1 = values[0];
val2 = values[1];
val3 = values[2];
val4 = values[3];
val5 = values[4];
val6 = values[5];
val7 = values[6];
val8 = values[7];
}
Notice that the top if is putting in hard-coded values and the bottom
one is using the values array I created. It's 4 times slower.
This makes using files over 5,000 rows very painful. And certainly puts
an upward limit on how much data I can slurp in.
Mind you that this is not a result of reading the file (very very fast)
nor creating the values array for each row. I am creating the values
array in both scenarios above. So that's included in the time.
Someone please tell me I'm being an idiot here somehow. Maybe I should
be using an ArrayCollection, or referencing values via the index of an
array is terribly slow... something obvious?
[flexcoders] Percentage based width in ActionScript
Yikes, I am creating a component in ActionScript and adding an HBOX to it as a child. I want that hbox to fill 90% of the width of this. I see on this page http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Partsfile=0518.html a comment about percentHeight, percentWidth In MXML tags only... Come on, really? This seems a very troubling shortcoming. I just know one of you gurus has figured out a simple fix for this, right?
[flexcoders] Determining VDividedBox heights
I'm trying to remember the height at which someone sets a vertically divided section. I am using a VDividedBox and have set a listener to the dividerRelease event. When I get in there I can trace out the height of the top component within the VDividedBox but it gives me the pre-resized value. I am assuming that the drop event happens before the redraw. Okay, not a shock. But what is confusing is that the VDividedBox object itself doesn't seem to have any getters nor properties for the size of the two boxes it is in control of. Am I missing something? I believe I can use the delta property on the event that is thrown and add that to the pre-resized value of the top box. I'm thinking that is a workaround, but am I missing something? Thanks
[flexcoders] Re: ItemRenderers and Events
Wonderful reply Tracy. Thanks. Bubbling the event, that's the perfect tip. As for not being able to walk the items in the list, that seems counter intuitive to me, but okay. As long as I know the behavior I can find a way and stop pulling my hair out wondering why I can't do what Flex doesn't do in the first place. Thanks a ton for the clear and very helpful reply. -M@ --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: If you are using dispatchEvent(new Event(change,true)) the second argument tells the event to bubble and you should be able to listen for it anywhere in the displayList, including the List, and Application. However, it sounds suspiciously like you are not having your checkbox renderer update the dataProvider. This is required. You cannot walk any array of elements inside the list You must look at the dataProvider only. The visual elements, including the checkboxes cease to exist when they are scrolled.

[flexcoders] AS Help
I have a hard question to ask as I don't know the terms to use for it.
Basically, I want to use a string variable to set what member variable
to pull from another object
How can I make something like the following work:
function fun(inString:String):String {
return preExistingObject.eval(inString);
}
[flexcoders] Re: AS Help
So, what I'm hearing is every member of an object is also added to an
associative array in that object by name? That's great news. I didn't
expect that level of DOM-type support from AS... I am learning every day
that these AS guys got a LOT right!
Thanks!

That would be equivalent to

For the current object, use this[inString].

[flexcoders] Content Clipping, how is it supposed to work?
I am trying to make a canvas (with rounded corners) clip the content inside of itself. It flat doesn't work. The clipping occurs, but the rounded corners are not taken into account, so the content inside is clipped to the square canvas. I have source below. Copy and paste that into the Flex Online Compiler http://try.flex.org/index.cfm (link: http://try.flex.org/index.cfm ) between the application tags to see what I am talking about. Is this a described behaviour? You will notice that I also put clipContent=true on the canvas in hopes that would actually help. Is there another way to produce the behaviour I'm looking for? mx:HBox width=100% height=100% horizontalAlign=center verticalAlign=middle mx:Canvas cornerRadius=25 clipContent=true backgroundColor=#FF borderStyle=solid width=150 height=200 horizontalScrollPolicy=off mx:HBox backgroundColor=#FF mx:Label text=This is text long enough to get clipped/ /mx:HBox /mx:Canvas /mx:HBox
[flexcoders] backgroundGradientColors on something other than Application
I was wondering if there were other elements (canvas, hbox, panel, etc) that can suport the backgroundGradientColors gradient properties? I see that there seems to be no support by default, is this simple to change?
