I'm trying to dispatch MouseEvent for HTML component in an AIR application. This way I want to simulate a click on HTML elements with ActionScript code. Here is my AIR app code:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
<![CDATA[
private function clickHTML(event:MouseEvent):void {
var e:MouseEvent = new MouseEvent(MouseEvent.CLICK,true,false,10,10);
html.dispatchEvent(e);
}
]]>
</fx:Script>
<s:Button label="Click HTML" x="10" y="10" click="clickHTML(event)"/>
<mx:HTML id="html" x="10" y="50" width="100" height="100"
location="page.html" click="trace('html was clicked')"/></s:WindowedApplication>
Here is the code for page.html:
<html>
<body onClick="alert('Clicked!')" bgcolor="grey">
Page loaded
</body>
</html>
When you click HTML element by yourself, there is an alert and MouseEvent, but when event dispatched with script there is only MouseEvent.
How to make it work?
You need directly call JavaScript functions in order to your html content do something.

I am a complete newbie to Flashbuilder, and I need to learn how to 1.) Embed a sound file (mp3) and 2.) be able to play said file.
I looked it up using Google and all the examples seem to be for AS3, I tried to adapt it as follows but cant get it to play (or should I say I can't hear anything?)
bgmusic is imported at the src level
Test.mxml:
<?xml version="1.0" encoding="utf-8"?>

I'm looking to animate a popup window using the effect.
The problem is that the effect is applied to the content of the popup window, not the popup window itself (including the title bar, minimize, maximize buttons etc)
Have a look at the result here..
My code is really simple and logically, should work if it is possible to animate a window.
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
<![CDATA[
import comps.MyWin;
[Bindable]
private var _win:MyWin;
protected function openPopup():void
{
_win = new MyWin();
_win.width = 300;
_win.height = 300;
_win.open();
}
protected function animatepopup():void
{
MyEffect.play();
}
]]>
</fx:Script>
<fx:Declarations>
<s:Move id="MyEffect" xFrom="{_win.x}" xTo="{_win.x + 150}" target="{_win}"/>
</fx:Declarations>
<s:layout>
<s:VerticalLayout/>
</s:layout>
<s:Button label="Open" click="openPopup()"/>
<s:Button label="Animate" click="animatepopup()"/>
</s:WindowedApplication>
I think you need to target the object's NativeWindow instance in order to move and resize the object.
Thus, replace _win.myProperty with _win.stage.nativeWindow.myProperty:
<s:Move id="MyEffect" xFrom="{_win.stage.nativeWindow.x}" xTo="{_win.stage.nativeWindow.x + 150}" target="{_win.stage.nativeWindow}"/>
Then, the animation will affect the NativeWindow and not the internals of the window.
I have not completly understood how custom components work...
Let's assume I have my Main.mxml application
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:local="*">
<fx:Script>
<![CDATA[
private var privateStr:String = "Stringa Private";
public var publicStr:String = "Stringa Public";
]]>
</fx:Script>
<local:AddUser height="100" width="500"/>
<s:Label id="lblText" x="120" y="120" width="418" height="115" text="!!!"/>
</s:WindowedApplication>
And the component AddUser.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
creationComplete="initialize_component()">
<fx:Script>
<![CDATA[
public var btnName:String = "Login";
private function initialize_component():void
{
login.label = btnName;
}
private function doLogin():void
{
//some stuff here
}
]]>
</fx:Script>
<s:TextInput id="txtuser" x="96" y="36"/>
<s:TextInput id="txtpass" x="96" y="66"/>
<s:Button id="login" x="96" y="96" width="128" click="doLogin()" />
</mx:VBox>
I would like that on the Button (login) click I get the publicStr/privateStr that are in the main.mxml...
Am I getting everything wrong? how can I use more components like they are all part of the same application and use the same variables/methods?
It seems like you're having issues with the idea of encapsulation. Child components shouldn't know about parent components, and View components shouldn't do real work, only request work from Controller components. In very simple projects, your top level component can contain the controller logic, but many people prefer to keep it separate even in small projects. How to do this is beyond the scope of this answer.
So, how should the parent and child properly communicate? Child components should expose properties that the parent (or Framework, if you're feeling ready to use a dependency injection framework) can populate with only the data the child components need.
Child components request work from the controller by generating events.
So, doLogin() would containe something like
dispatchEvent(new Event('doLogin'));
and the parent component would be listening for this Event. In its handler, you would perform the login. More than likely, your login would be asynchronous, so you'll need another handler to listen for the login data to come back. When the login data comes back, you will then set the properties on the login View based on the return.
I'm having a weird behavior. I have an HTML link inside a TextFlow. When I set its linkHoverFormat, it starts sending rollOver/rollOut events up the chain. These events say the don't bubble but somehow they do. And I can't seem to stop them from doing so.
Here's an example:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Declarations>
<s:TextLayoutFormat id="linkNormal" textDecoration="none" color="0x556677"/>
<s:TextLayoutFormat id="linkHover" textDecoration="underline" color="0x0000FF"/>
<s:TextFlow id="textFlow1"
linkActiveFormat="{linkHover}"
linkHoverFormat="{linkHover}"
linkNormalFormat="{linkNormal}">
<s:p> <s:a href="http://projects.nunogodinho.com">hover</s:a> </s:p>
</s:TextFlow>
</fx:Declarations>
<fx:Script>
<![CDATA[
// This pair of handlers is triggered by the panel
protected function rollOverHandler(e:MouseEvent):void {
panel.title = "over";
}
protected function rollOutHandler(e:MouseEvent):void {
panel.title = "out";
}
]]>
</fx:Script>
<s:Panel left="10" top="10" id="panel" mouseOver="rollOverHandler(event)" mouseOut="rollOutHandler(event)">
<s:RichEditableText id="ret1"
top="10"
editable="false"
textFlow="{textFlow1}" />
</s:Panel>
</s:WindowedApplication>
If you run this app and move the mouse over the link several times without moving out of the panel you'll see that it still changes the text.
So I decided to try to stop this strange event from bubbling:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"

<s:TextLayoutFormat id="linkHover" textDecoration="underline" color="0x0000FF"/>
<s:TextFlow id="textFlow2"
linkActiveFormat="{linkHover}"
linkHoverFormat="{linkHover}"
linkNormalFormat="{linkNormal}">
<s:p> <s:a rollOver="linkelement2_rollOverHandler(event)" rollOut="linkelement2_rollOutHandler(event)" href="http://projects.nunogodinho.com">hover</s:a> </s:p>

<![CDATA[
import flashx.textLayout.events.FlowElementMouseEvent;
// This pair of handlers is triggered by the panel
protected function rollOverHandler(e:MouseEvent):void {

panel.title = "out";
}
// This pair of handlers is triggered by the <A> element inside textFlow2
// and I hoped it would stop the event from bubbling up to the panel
protected function linkelement2_rollOverHandler(e:FlowElementMouseEvent):void {
e.preventDefault();
e.stopImmediatePropagation();
e.stopPropagation()
}
protected function linkelement2_rollOutHandler(e:FlowElementMouseEvent):void {
e.preventDefault();
e.stopImmediatePropagation();
e.stopPropagation()
}
// I also tried to intercept the event in the RichEditableText but got the same weird
// behavior: the event triggers the panel's rollOver/rollOut intermittently
]]>
</fx:Script>
<s:Panel left="10" top="10" id="panel" mouseOver="rollOverHandler(event)" mouseOut="rollOutHandler(event)">
<s:RichEditableText top="10" left="55"
editable="false"
textFlow="{textFlow2}" />
</s:Panel>
</s:WindowedApplication>
I tried all combinations of preventDefault, stopImmediatePropagation and stopPropagation. It does change the event's behavior but it also ruins the hovering effect on the link.
Then I tried to intercept the event at the RichEditableText but I got the same kind of results.
Once I had a similar problem but I learned that it was because I was using mouseOver/mouseOut events instead of rollOver/rollOut. Since I switched to rollOver/rollOut it worked fine. Until now.
And now I'm clueless.
Please help.
Thanks.
I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that?
Here's my parent:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

<![CDATA[
import pup;
import mx.managers.PopUpManager;
public function showPup(evt:MouseEvent):void {
var ttlWndw:pup = PopUpManager.createPopUp(this, pup, true) as pup;
PopUpManager.centerPopUp(ttlWndw);
}
]]>
</fx:Script>
<mx:VBox>
<local:pup id="pupLove" visible="false" includeInLayout="false" />
<s:Button click="showPup(event);" label="launch Pup" />
<mx:Text id="Ptest" color="black" text="from Parent:{pupLove.dg.length}" />
</mx:VBox>
</s:Application>
And a popup child called 'pup.mxml':
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"

</mx:VBox>
</s:TitleWindow>
</s:Group>
UPDATE: I guess my question can be more easily stated as: "is there a way to call a child's function from the parent without actually loading the child?"
Well, if in your child's function, you don't need to access any of its UI component, then you could instanciate the child in the parent view and call the method.
When you need to display the popup afterwhile, use the PopupManager addPopup method with this existing instance instead of using createPopup
