Re: [flexcoders] Quickest way to test whether something is an Object not a subclass?
You could use the top level operator provided by Flex. The 'is' operator.
Say I have a object of class ArrayCollection like below:
var tmp:ArrayCollection = new ArrayCollection();
Now I can use the 'tmp' variable in following way:
if (tmp is ArrayCollection)
the result of the above if statement would be true. Same goes with the
Object. If I have a class derived from Object and use the above if statement to
see if the class object is Object, it would return me false. It would return
me true for the class type which extends the object.
Else you have a
getQualifiedClassName
()method in the utils package as mentioned by Alex, to do the same thing.
I hope this might help you.

Amol.

Nope, not for Object
is returns true for every parent class type
Button is UIComponent == true
Button is Object == true
and in your example you will actually find tmp is Object == true
So no that wont work when its Object were talking about..
but getQualifiedClassNa me works just fine

Re: [flexcoders] Scroll Position
Hi, You may use the following properties which all the containers in Flex have to do the set the scroll position. Check out the conainer properties which you would see in the Flex Help. Some of them are below : horizontalLineScrollSize : Number Number of pixels to move when the left- or right-arrow button in the horizontal scroll bar is pressed. horizontalPageScrollSize : Number Number of pixels to move when the track in the horizontal scroll bar is pressed. horizontalScrollPosition : Number The current position of the horizontal scroll bar. The same goes well replacing horizontal with vertical for the vertical scroll control. You can set the scroll value for the verticalScrollPosition property of the Canvas to get the desired output. like... canvasInstance.verticalScrollPosition = 30, where '30' could be your calculated value.

However, I don't want this to always start at the top, but is dependant on the user.

Re: [flexcoders] properties in components..
Hey Paul,
Cool down men. See whenever we write a script in an mxml file you need write
that script in a function.
For example:
Your code was:
mx:Script
![CDATA[
x.label=jim ;
]]
/mx:Script
Put the same thing this way:
mx:Script
![CDATA[
function init() {
x.label=jim ;
}
]]
/mx:Script
and call this function when you load the the mxml on the creationcomplete event
like this:.
this will solve your purpose.
Amol.

Subject: [flexcoders] properties in components..
OK, this is driving me nuts. I'm using Flex Builder 2.01 on a PC.
I have a very simple component (say test.mxml), code below, where I set a
label value on a button using actionscript.
I can get this to compile very simply and we're all happy.
As soon as I edit the main application( main.mxml) to include this component:
comp:test
/comp:test
main.mxml is happy but now I get a compile error (access of undefined
property) in test.mxml saying that the button id is an undefined property.
When I edit the test.mxml code, flexbuilder will happily give me code hints
about the properties after I've put in the button id.
What's going on? Maybe I just need more coffee?

Re: [flexcoders] Getting a Sprite into a Flex Container?
Hey Sascha,
I hope this is what you were looking for.
I have a class which extends Sprite as below:
package {
public class myShape extends Sprite {
.
.
.
.
.
}
}
Now I have my owns custom component class file which I have added as follows:
First in the Application tag of your mxml file, mention a additional attribute
as 'xmlns:greet=com.*'. Here refer to the package where your custom component
class is.
Now use following to add the component to the Flex mxml file:
greet:test id=apiref /
Here 'greet' is the xmlns which we added in the application tag and 'test'
is my custom component class. You have to be careful to extend your custom
component class with the UIComponent class like:
package com {
//import myShape class if not in same package.
public class test extends UIComponent {
..
public function test() {
var shapeObj:myShape = new myShape();
addChild(shapeObj);
}
.
}
}
Now in the test class you can add the earlier Sprite extended class by creating
its object as above.
This should solve your purpose. Now the above mentioned test class can extend
any of the Classes like Canvas, or any container class. But UIComponent
happens to be the base class to all the container classes n so UIComponent
could be best opted choice.
Regards,
Amol.

Hi,
I got a class that extends Sprite that I want to put into a Flex
DisplayObject container (Canvas or any similar custom made component). My
question is:
Is implementing the IUIComponent interface the only way to get this working
or
Are there any other ways around it? A SWFLoader is not what can use in this
situation. Any hints would be appreciated.
Thanks in advance,

I think it's read only with non-editable comboboxes. - Dan On 12/15/06, Paul Hastings paul.hastings@ gmail.com wrote: i can't seem to catch hold of where user input data is going for editable comboboxes. i've tried selectedLabel, selectedItem, cruising the data provider, etc. i guess i'm missing something. do i need an event listener for this? thanks. __ Do You Yahoo!?
