Subject: [flexcoders] Catching graphics update on UIComponent
I have a UIComponent that is a component made up of a label and a background
image. I am running a loop to update the component, change the label and copy
the resulting bitmap to a standard image. My result is that I get the image
without any updates. The add function just pushes the counter of the label up 1
and updates the .text field of the label. The code looks like...
I know invalidatedisplaylist just adds a flag to a future update but how should
this be built.
var curX :int = 10;
var curY : int = 70;
var anImage : Image;
var imageBitmapData:BitmapData ;
while (curY this.height) {
bbMain.add(1);
if (curX this.width) {
curX += 60;
} else {
curY += 60;
curX = 10;
}
this.invalidateDisplayList();
// Copy into new image
anImage = new Image();
anImage.width = 54
anImage.height = 54;
anImage.x = curX;
anImage.y = curY;
this.addChild(anImage);
imageBitmapData = ImageSnapshot.captureBitmapData(bbMain);
anImage.source = new Bitmap(imageBitmapData);
}
Re: [flexcoders] newbie question : putting a semicolon in a mxml property
Not if there is just a single line of script within the quotation marks. If you wanted to do something like this though, mx:Button label=some label click=t1.text = t2.text; doSomethingElse(); t3.visible = false; / Then you do need the semi-colons. Most people just have the semi-colon there out of habit from when they write AS in .as files or within the mx:Script tags (they are needed in those cases). 2009/7/12 ew6014 ew6...@yahoo.com: hi guys i was reading the flex documentation and i noticed a ; inside a mxml property let me give you an example mx:Button label=some label click=t1.text = t2.text; / ive tried removing the semicolon ; and also tried leaving it there and there was no error of any kind. so im just wondering if this will cause issues or is something going on that i do not know thank you guys in advance -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Alternative FAQ location: https://share.acrobat.com/adc/document.do?docid=942dbdc8-e469-446f-b4cf-1e62079f6847 Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.comYahoo!

[flexcoders] flash button in flex issue
I got another problem.
In flex I can only reference the flash button by its ID property.
Most of the time I can't know its ID. I need cover it to a super class like
MovieClip Instead of that.
How can I fix this ?

[flexcoders] Image control reports wrong size
My app needs to display an image inside a VBox, with content auto-scaled to fit
the width of its container, and the VBox height adjusted to accommodate its
children.
The problem arises when the loaded image has content width VBox width, i.e.,
when the image content is scaled to fit --VBox appears to be using he original,
unscaled height of the image, rather than its scaled-down height, so I end up
with extra whitespace below the image.
Similar behavior when I put the image in a Canvas, so it's not the container,
but the image that is reporting incorrect height after scaling. I've posted an
example to demonstrate the issue, at: http://data.uniontrib.com/ScaleTest/
(view source enabled).
I came up with an unsightly work-around that computes the proper height of
the image once it has loaded and scaled, and assigns this to a bindable var
that sets the height of the image... e.g.:
mx:VBox id=myVb width=100
mx:Image id=myImg scaleContent=true source=fx.jpg
width=100% height={properHeight}
complete=computeProperHeight()/
/mx:VBox
...
[Bindable] private var properHeight:Number;
// run on complete of image load
private function computeProperHeight():void
{
properHeight = (myImg.width/myImg.contentWidth)*myImg.contentHeight;
}
If anybody has a better idea, I'd love to hear it.
RE: [flexcoders] BrowserManager not working
Hi. Thanks for your response.
After some more troubleshooting the problem is the following:
the URL is returned correctly by the following code:
import mx.managers.BrowserManager;
import mx.managers.IBrowserManager;
import mx.utils.URLUtil;
import mx.utils.ObjectUtil;
private var bman:IBrowserManager;
private var url1:String;
bman = BrowserManager.getInstance();
bman.init();
url1 = URLUtil.getServerNameWithPort(bman.url);
trace(url1);
but then I do this:
if (true) {
var u:URLRequest = new URLRequest(url1);
navigateToURL(u,_self);
}
Basically I want to reload the original URL on certain conditions.
This time when the page loads the bman instance is null.
So the URLRequest object does not contain the information that
BrowserManager needs.
Would this be to do with the request headers...?
How can I solve this...?
Thanks
Kr.

if you just did dataGrid.selectedItem then that would be the selected row. add
[columnname] to get to the column, so:
dataGrid.selectedItem[columnname]
it's not the label, it's the data column name.

[flexcoders] Trying to change Flex 3 ToggleButtonBar dataprovider on user or admin log in
Hi all,i'm trying to change Flex 3 ToggleButtonBar dataprovider on user or admin log in..I'm trying to use 2 viewstack,one for user,one for admin and i got a component where the login form is in the component..What should i do to define the dataprovider on the mainbased on user log in??Thanks a lot...
[flexcoders] Re: This is not as easy as it seems ... apparently...
Ok... In the parent component to the datagrid I used an initialize event:
public function initDg():void {
if(dgOrdExt.selectedItem[Kind]==LONG)dgOrdExt.Profit.dataField=Profit;
if(dgOrdExt.selectedItem[Kind]==SHORT)dgOrdExt.Profit.dataField=ShProfit;
}
it does not work. but if I replace the code with dgOrdExt.dataField=Profit;
which just sets the dataField without referencing the other column the code is
all working...
I also tried creationcomplete event and that did not work either.

You can't use selectedItem because there is no selectedItem. You haven't
clicked a row. Try looping through the grid.
In the end, I really don't understand why you don't do this in the
dataCollection, or even in the source data.
for (var i:Number = 0; i mygrid.numChildren; i++) {
if (mygrid.getChildAt(i)[Kind] ==

mygrid.getChildAt(i)[Profit]

yes the datagrid is bound to an array collection.
I don't want to select any item, I want to change the value of a column's
DataField to a one of two values based on the value of another column's output.
I don't want to have to 'selecteditem' but I can try that code below are you
suggesting that I use it in the labelfunction of the datagrid column that I am
trying to change?

I can not figure out how to access the value of the Datagridcolumn. I
have tied using event listeners, etc.. which did not work. Please let

now we're getting somewhere! but will this update the value of the col2 or the

Can I use:

That'll update the value of the cell.
You can't do what you're trying to do. You can't have a column with a
different dataField per row. The dataField for the column is the same for
every row.
Is this data coming from a database, through a view? You really should do this
there. You can set up a view column with an if/then that returns the column's
value you want.

[flexcoders] Loading External wysiwyg editor
Hey All, I have been playing with some options to try and get a better editor to work in Flex. As we all know, the RTE that comes as a standard control in Flex is a but limited, and I thought to try and get one of the javascript based editors to load. Does anyone know if it is possible to load lets say TinyMCE into a Flex app? If not, is anyone aware of a way to extend the functionality of the supplied Flex RTE to allow for additoinal html formatting? Thanks! Jonathan
