[flexcoders] Re: problem with cell renderer in ComboBox
Just sharing the solution I got for this with Flex Support. I
basically just used the labelFunction attribute.
mx:Script
function formatName( item ) : String {
return item.firstName + + item.lastName;
}
/mx:Script
mx:ComboBox id=employeeComboBox labelFunction=formatName
dataProvider={ModelLocator.employees}
/
I still wondering why the cellRenderer solution didn't work.
cheers,
George

quite surprising this didn't work for you. i took this idea from
Peter Ent's weblogs. check out the cellrenders section
http://weblogs.macromedia.com/pent/archives/2004/12/index.cfm
the code can be downloaded and there is a sample test app to see it
in action. its very good.

Re: [flexcoders] Re: problem with cell renderer in ComboBox
As far as I recall, dropdown object can be
"dropped" and recreated when the data model and other things change. If you do
not reassign cellrenderer at that time it will be gone. It would make sense to
me to subclass the object and override getDropdown function to assign
cellrenderer on each call or at least when dropdown was not defined at the time
of the call.
Thank you,
Anatole

Re: [flexcoders] Re: problem with cell renderer in ComboBox
Bod,
We are actually supporting our
DGComboBox as a standard object in our framework. As far as Flex 2, it is also
supported - just implementation is different - listItemRenderer is dynamically
created instead of grid. So there is no code changein the application -
just internal implementation is different.
However, if you are "starting fresh" with Flex
2 and do not want 3rd party components this will do:
mx:ComboBox labelField="fname"
dataProvider="{..}"
width="200"
mx:listItemRenderer
mx:Component verticalGap="0"mx:HBox xmlns:mx="http://www.macromedia.com/2005/mxml"
xmlns="*" verticalGap="0" hScrollPolicy="off"
vScrollPolicy="off"
mx:Label text="{dataObject.fname}" width="50%" /mx:VRule
height="20"/
mx:Label
text="{dataObject.lname}" width="50%"/
/mx:HBox
/mx:Component
/mx:listItemRenderer

Re: problem with cell renderer in ComboBox
Ill file a request for the dropdown
but I dont know the reasons behind its structure. You can at least
use ComboBase as a starting point if List wont cut it for you. As
for introducing more interfaces, we had them at one point and I think we found
that it was getting out of hand without much value. The source is going
to be available so you should be able to copy and modify for the ones that
dont work out exactly as you need.

Matt,
Is it possible to downgrade
ComboBox::dropdown property in the next beta/final release to ListBase so the
subclassing/ability to show more complex dropdowns is possible? Also, what are
the chances of relaxing base types of the internal properties of the controls a
bit (when it does not affect performance) from strongly typed to lower
levels/split them to interfaces.
Without code decoration/polymorphism in
the base objectsthe current architecture is much more code and time
consuming forcontrol development and can be showstopper for 3rd party
controls.

Here, ModelLocator.employees is an array of custom vo objects. How
do I access the individual attributes of each vo object in this
scenario?

Subject: [flexcoders] problem with cell renderer in ComboBox
Hi,
I had a cellrenderer that was originally used in datagrid cell.
I've
since replaced the datagrid with a comboBox. I'm trying to reuse the
same cellrenderer in the combo using the code below.
mx:ComboBox id=employeeComboBox
creationComplete=
event.target.getDropdown().cellRenderer='com.sf.sfv4.view.sharkfin.Full
NameRenderer';
event.target.getDropdown().variableRowHeight=true rowCount=10
mx:dataProvider { ModelLocator.employees } /mx:dataProvider
/mx:ComboBox
The FullNameRenderer cellrenderer I have just takes the first and
last
name of a user vo and concatenates it.
However this isn't working for the combobox. I get and set the
cellrenderer of the combobox's dropdown property as stated in this
group by another member, but it doesn't work. Instead I get the
user
vo object displayed.
I'm confused, I'm using the same dataProvider and cellrenderer in
the
combobox as I did in the datagrid. I think there's a difference
between the two widgets, but I just don't know what it is.
Please advise...
TIA,
George

[flexcoders] Re: problem with cell renderer in ComboBox
why dont you simplify things a bit. put your FullNameRenderer into
the same folder location as your ComboBox mxml application.
and do this
mx:ComboBox creationComplete=test(event)
function test(event){
event.target.dropdown.cellRenderer = FullNameRenderer;
}

[flexcoders] Re: problem with cell renderer in ComboBox
i would also like to see the dropdown property made into
a 'Read/Write'.
i had to override the getDropdown() method which gave me problems
when going from flex1 to 1.5 (i know this method is not in the api)
other technologies such as PowerBuilder is not an issue.

Re: [flexcoders] Re: problem with cell renderer in ComboBox
You can make the property writeable in 2.0 - just
add setter method in the inherited class. The issue is thatmost of
thetimes you access the property, explicit typecasting is made by compiler
-causing exception if you are using "unrelated"
datatype.
Oneapproach to solve this issue would be to
have another compiler keyword that bypasses type checking with dynamic
resolution on the variable level like
override dynamic var
dropdown;
That would obviously cause serious update to the
typecasting statements making them "quiet" - basically 1.5 behavior that is not
advertised, but available for hackers - probably would be banned by archtects
and remain unused by corporate developers.
Other well-defined approach is to seriously
reevaluate extensibility of the product and extend it with tons of interfaces.
Has been tried number of times with Java, never (to my best knowledge)
commercially successfully with front-end large scale tool. In the
end/maintenance stage, I always had to do "fine tuning" by using
Javascripting products like beanshell.
That leaves the third approach I like most. I am
glad you (presumably unconsciously due to similar problem) remembered
PowerBuilder scripting language.PB also had single inheritance and no
decorations. At a certain maturity level they decided to do strong type checking
and optimization at the expense of "scripting power tricks". The problem was
that they had significant user base at the time of the change and could not
afford to loose early adopters.
However, they solved this problem with simplicity
and pragmatism that always win the users appreciation. They allowed method call
modifier "dynamic". For simplicity I will switch PowerBuilder typeANY to
Object :
class a { function test(x:int){ return "a"}}
classb { function test(y:string){ return
"b"}}
//example of usage
var o:Object = new a(); o.dynamic test(5);o.invoke("test",
5);
var o:Object = new b(); o.dynamic test("abc");o.invoke("test",
"abc");
They also made sure that events (seldom called as response to user
interaction/internal changes) are staying dynamic - no strong type checking
there - no need for endless switch/case statement typecasting the event type and
missing the new ones as thecontrols baseis extended.
The "legacy" code was saved by trivial replace of non-compiling statements
with dynamic calls, the "core" run-time code base by using similar trick
retained higher percentage of the previous versions tested code that continued
to work. Main objective - giving application developers more "strict"
intellisense environment eliminating typos while allowing for more dynamic
coding when needed worked very well.
Hope it can be integrated in the current version of the compiler.
Thank you,
Anatole Tartakovsky
P.S.
It would be interesting to get feedback from the current Flex developers
who have production applications in 1.5 on the chances/effort of the conversion
from 1.5 to 2.0. That very well might give an indication of importance of the
language changes - it very well might be just my imagination. That of course is
only important if those applications have to be upgraded to 2.0.
Some other scripting languages are also subject for review as the
integrationsimplicity and power of those keep driving the users trends - PHP and
Phython is a good example what integration model can do to the environment by
enabling 3rd parties.
