 Subject: [flexcoders] problem with a for each loop
 
 
 
 Hi, I got a problem with a for each loop.
 
 I have a class (B), B has a long inheritance chain where the oldest
 ancestor is class A.
 Class A does not declare an extension of any other class therefore I
 take it that it extends the Object class:
 
 All classes that don't declare an explicit base class extend the
 built-in Object class.
 http://livedocs.macromedia.com/flex/2/langref/Object.html
 http://livedocs.macromedia.com/flex/2/langref/Object.html 
 
 Somewhere in my code I'm trying to use a for each loop in order to
 explore the members of B.
 
 [code]
 var obj = Object(instanceOfB);
 
 for each(var prop:Object in obj){
 //do some thing (my code never gets here)
 } 
 [/code]
 
 The problem is that although B (and instanceOfB ) has a number of
 members the for each loop ignores them all and never goes in side
 the loop.
 (I used the casting in order to demonstrate that I'm actually using an
 inheritor of the class Object)
 
 What am I doing wrong here?





[flexcoders] Re: problem with a for each loop

2006-12-12 Thread leo4beer
i have another question:

when I do the following:

for(var prop in instancOfB){
 //gets here only once as if instancOfB has only one member
}


bur if I do the following: 

for each(var prop in instancOfB){
//will show the values of all props
}

the problem is that for each will not give me the prop name but only
the value. a simple for gives me a name and value but fails to show
all props.

[flexcoders] Canvas – getting the topmost viable pixel

2006-09-03 Thread leo4beer
Hi, I'm using flex 1.5.

I have a canvas with a scrollbar; the canvas content may be resized or
scrolled, each time it's resized I'd like to know the number of the
topmost pixel that is viewable.

I know this number exists and is used when extracting vPosition,
according to the docs vPosition is equal to the distance (in pixels)
between the top edge of the scrollable surface and the topmost piece
of the surface that is currently visible., what I'm looking for is
the topmost piece of the surface that is currently visible.

Any ideas?

Thanks.

 Sorry, I see that you said Flex 1.5. You would override draw()

[flexcoders] Accepting MXML attribute's width in percentage on a custom component

2006-05-15 Thread leo4beer



Accepting MXML attribute's width in percentage in a custom component

Hi, I have a component I've created by inheriting UIObject class

In my mxml I have the following lines used for initiating my component:

my:comp width=400….

In my AS code I can trace the value of __width, in this case the
result will be 400.

My problem is that when I set the value as percentage:

my:comp width=100%….

In this case the value of __width is undefined

What should I do in order to get the correct value when setting the
width in percentage and not in pixels??

Thanks

[flexcoders] Source code for Macromedia Flex 1.5 components?

Hi, I was wondering where the source code for Macromedia Flex 1.5
components could be found.

I have the classes that can be found in FlexForFlash.zip distributed
with MX2004, I've also found Flex classes in Flash 8 folders.
Both versions seem to be identical; they also seem to be compliant
with Flex 1.0 and not Flex 1.5.
 
I was wondering if anyone knows where I can get the source of Flex 1.5
components.

Thanks.

[flexcoders] Best practice for building AS components for Flex

2006-05-05 Thread leo4beer



Hi, I need to make a number of features to be included in a Flex 1.5
application.
These features are relatively complicated and therefore should no be
coded in MXML.

for instance on of the features is a fully functional gahnt chart,
users may be able set session and events using that chart.

I can think of a number of methods for doing this:

1. extend one of the relevant Flex components like the Chart
component, add additional components as children.
2. extend a container component and code the entire feature using AS,
add additional components as children.
3. Use the Flash IDE and prepare an application by dragging and
dropping Flash for Flex components, make the relent code changes and
compile everything as a Flash component.

So far I've been aiming for option 2. I've been using an article
titled Developing Flex Components and Themes in Flash Authoring from
Macromedia.

Do you think this is the right approach?
What would you do?
Are there any other options available?

Thanks in advance,
Leo.

[flexcoders] scrolling inside an AS based component

2006-05-04 Thread leo4beer



Hi

I'm building an AS component for Flex (using as only).
My component will contain a dynamic nap loader which the users may be
able to scroll.
Obviously I will need to combine a scroll component inside my

does not consist this class (I guess Flex has better alternatives)
What should I use in order to enable scrolling with pure AS component?

 The easiest option is to make your component a *container* by
 extending mx.core.Container. Lay out the children in
 'updateDisplayList' (you probably have only one child at 0,0) and the
 scrollbars should show up automatically if the child is larger than
 the container's area.
 
 There's a difference between containers and controls. If you strictly
 want your component to be a control, then you could also extend it
 from mx.core.ScrollControlBase and calling the 'setScrollProperties'
 method in your 'updateDisplayList' implementation. See a recent thread
 on this forum about this topic.


Thanks, I also will check that thread...

 Not sure which version you are using, but in Flex 2 Beta 2, I also have

 When you say you are using the drawing API, I presume you are doing 
 something like this:
 
 this.graphics.clear();
 this.graphics.beginFill(0xff);
 this.graphics.drawRect(-25, -25, 50, 50);
 
 One thought is that you may not be setting the line color or line
width. 
 Is that a possibility? Make sure you have something equivalent to this:
 
 c.graphics.lineStyle(1, 0xff);

 Hmm...
 
 Then you'll have to settle for masking. There's plenty of examples on
 the web of how to use a mask.

[flexcoders] Re: scrolling inside an AS based component

2006-05-04 Thread leo4beer



Sorry Manish but I don't think I follow you...

I know what setting a mask means, my problem is making my content
respond to a scroll bar. in Flash I would do this using the scroll
pane. how would I do this in a Flex application using AS code only?

Thanks again for your time and sorry for my ignorance :) , I've been
developing for Flash for many years now, I switched to Flex and still
trying to learn the diffrences.

Leo.

 Setting a mask does not affect scrolling. So scrolling will work as it
 does normally.

[flexcoders] Re: Embedding the fonts of a Tab Label.

Thanx for the reply, I'll be using icons and not text labels.

 Have you made sure the font is truly embedded, using one of the
 techniques mentioned in the docs?

 Embedding the fonts of a Tab Label...
 
 Hi, I'm extending the TabBar class in order to make a vertical tab
 bar...
 When I rotate a tab the fonts must be embedded otherwise they will not
 appear.
 Currently my main problem is embedding the fonts. 
 
 I've tried embedding the font in various ways:
 
 
 //child is a tab, I'm referring to it in a loop when overdding the
 base class layoutChildren() method
 child.labelPath.labelField.embedFonts = true;
 //or
 child.labelPath.setStyle(embedFonts, true);
 
 both methods did not work and I'm unable to view the text...
 
 Any ideas?
 
 Thanks in advance.

[flexcoders] Strange ComboBox problem

2006-04-11 Thread leo4beer
Hi,

I've ran into a bug I'm unable to trace, I was wondering if anyone
here encountered this (so far I could not find anything on the web)

I'm extending a Flex control, in my new class I'm attaching a ComboBox
to the control. The problem is:

When I change the CB selection for the first time the selection is
ignored, instead it gets back to it's default selection.
This will happen only on the first time and after that the CB behavior
is normal.

Any ideas??

Thanks.
