Re: [Flashcoders] Call method by name: A few questions...

2011-01-18 Thread Micky Hulse 
Here is my latest solution:

Document class:

===

import com.foo.util.GoogleMaps;

...

_map.controls = ['PositionControl', 'ZoomControl', 'MapTypeControl',
'ScaleControl', 'OverviewMapControl'];

===


Here's com.foo.util.GoogleMaps:

===

import com.google.maps.controls.*;

...

private function onMapReady($e:Event):void {
for each (var s:String in _controls) {
this['my' + s]();
}
};

...

private function myZoomControl():void {
_map.addControl(new ZoomControl());
};

private function myPositionControl():void {
_map.addControl(new PositionControl());
};

private function myMapTypeControl():void {
_map.addControl(new MapTypeControl());
};

private function myScaleControl():void {
_map.addControl(new MapTypeControl());
};

private function myOverviewMapControl():void {
_map.addControl(new MapTypeControl());
}

...

public function set controls($a:Array):void {
_controls = $a;
};

===

I am sure to all ya'll pro AS3 coders, the above looks pretty silly... :)

I don't think I will actually use the above code in my final
program... I just thought I would share a working solution.

Thanks again for all of the help! I really appreciate it. :)

Cheers,
Micky

Hi All! Many thanks for the replies, I really appreciate the pro help. :)

See inline replies below:

Doh, sorry if my question was a little convoluted and ambiguous. :(

Thanks for tip! In this case, I would like to do something like this:

for each (var s:String in _controls) {
new com.google.maps.controls[s]();
}

Unfortunately, that does not work. :(

> Not if you have a property of the object that is an array.

Ahh, not in this case.

My document class is calling the "controls" setter like so:

_map.controls = ['PositionControl', 'ZoomControl', 'MapTypeControl',
'ScaleControl', 'OverviewMapControl'];

Where each is a class method of com.google.maps.controls.

Based on your feedback, it is sounding like what I am trying to do is
bad practice. Basically, I was just trying to avoid writing a setter
for each type of map control.

Ah, interesting! You know, I come across this function via Google, but
I was not able to grasp how to properly use it in this situation...

This is the class:

com.google.maps.controls

And this is a method of the class (for example):

ZoomControl()

I have tried a few different variations of the below code with no success:


var classRef:Class = getDefinitionByName('com.google.maps');
for each (var s:String in _controls) {
// Test #1:
//var classRef:Class =
getDefinitionByName('com.google.maps.controls.' + s + '()');
//var controls = new classRef();
// Test #2:
new classRef.controls[s]();
}

Nine times out of ten I get this error:

[[

Implicit coercion of a value with static type Object to a possibly
unrelated type Class.

]]

This sounds interesting! Could you clarify a bit further? I am not
sure where I should do this.

Thanks again everyone! I greatly appreciate the pro assists on this one. :)

You must declare each class or they are not gonna be compiled. Just put all
the class names you need separated by comma: ZoomControl, PositionControl,
ScaleControl;

You want the getDefinitionByName function, not the dynamic property 
access syntax.

I'm not sure if this is what you're asking for.

> 1. How to call com.google.maps.controls.* methods by name?

new com.google.maps.controls.ZoomControl();

> 2. Is it bad practice to pass an array to a setter?

Not if you have a property of the object that is an array.

[Flashcoders] Call method by name: A few questions...

2011-01-14 Thread Micky Hulse 
Abbreviated AS3:

==

import com.google.maps.controls.*;

// Setter:
public function set controls($a:Array):void {
_controls = $a; // Array of string method names.
};

private function onMapReady($e:Event):void {
// This works:
_map.addControl(new ZoomControl());
// This does not work:
for each (var s:String in _controls) {
// Call methods by name... But, how?
_map.addControl(new this[s]()); // Gives me error.
// How to refer to the imported "com.google.maps.controls" 
instead of "this"?
}
};

==

I really want to call com.google.maps.controls.* methods by name, but
when I try (see "new this[s]()" line above) I get this error:

[[

Property ZoomControl not found on my.package.util.GoogleMaps and there
is no default value.

]]

Where "ZoomControl" is just one of the possible control methods that I
want to call.

Questions:

1. How to call com.google.maps.controls.* methods by name?

2. Is it bad practice to pass an array to a setter?

3. If #2 answer is yes, would it be best to just have one setter per
"control" method?

Am I making any sense here? :D

Please let me know if I can clarify further.

Thanks!
Micky
