Custom with the custom event handling/propagation class
Hello
I m trying to figure out, how we could extend a custom class so that other classes could enter the headphones to this custom class
and will be informed by raising an event in this custom class.
I can´t find any documentation about it. The post of oracle on the management of the event to
http://docs.Oracle.com/JavaFX/2/events/jfxpub-events.htm
doing business only about the event target and the string of events.
But to my understanding, I need to know how this custom class could be extended to be an EventSource?
I could extend my node, scene or window class to get all the things in the event by legacy, but I think that
that is not the right way? Not everything is a node
As indicated in the article
If your control or element of your control is not a subclass of
Window
,Scene
, orNode
, you need to implement theEventTarget
interface for this control or element.
I must apply EventTarget and its method
@Override public EventDispatchChain buildEventDispatchChain(EventDispatchChain edc) { throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates. }
But it is a target? And the source?
I m a bit confused.
Help would be great for a beginner, some shooting events
THX

Would what type of event you like fire? Perhaps using the framework of the event in javafx.event is more you need. What if all you want to do is to inform listeners that some State has changed, you should consider using javafx.beans.Observable or one of the classes implementing this interface.

The onDeactivate event handler does not work in InDesign CC. Why?
Hi guys.
I'm working on a script in Javascript for InDesign CC.
The big problem is that the onDeactivate event handler does not work.
Here is an example that works in InDesign CSx, but not in InDesign CC:
#target indesign var w = new Window ("dialog", "Test onDeactivate"); var et_1 = w.add("edittext", [undefined, undefined, 300, 30], "Lorem ipsum"); var et_2 = w.add("edittext", [undefined, undefined, 300, 30], "Dolor sit amet"); var st = w.add("statictext", [undefined, undefined, 300, 30], "CONSOLE:\r\r", {multiline: true}); et_1.onDeactivate = et_2.onDeactivate = function(){ st.text = "CONSOLE: I left the field with this text:\r\t«" + this.text +"»"; } var b_ok = w.add("button", undefined, "OK"); w.show();
The script displays a dialog with text edit fields window 2: when a field loses focus (by clicking on the other), the "CONSOLE" shows the text of the old domain.
Adobe, please, solve this problem as soon as possible.
Thank you.

Problem with the onChange event
Hello
I am currently facing a problem with the onChange event when you use a datefield entry type.
for example
< cfinput type = "datefield" name = "date_txt" width = "175" mask = onFocus = "date_txt.disabledDays" dd/mm/yyyy"= [0.6]; "tabindex ="1"style =" "text-align: left" onChange = "checkDate (); ">
And then, when I alert the selected date in checkDate function, I still get the old figure.
for example
public function checkDate (): Void {}
Alert ("Date:" + date_txt.text);
}
For example if the date displayed is 05/05/2008 and I select another day (05/02/2008), then when the alert box appears, it still shows 2008-05-05.
Any idea on how to solve this problem?
Is this a bug with Flash Forms?
Thank you and best regards,
Yogesh MahadnacI suppose that the function onchange occurs before the value of text is actually defined.
Use the correct value
Alert ("Date:" + date_txt.selectedDate);Ken

stimulate the touch event handling in PRC?
I want to stimulate the touch event in another application. can someone help me in explaining to me with a code example.
I'll pass on this one, whenever I give you an answer to a topic, change you what you wanted in the first place.
First of all, you wanted to listen to the event:
http://supportforums.BlackBerry.com/T5/native-development/touch-does-not-fire-for-Q10/TD-p/3026980Second, you were finally made in the PRC:
http://supportforums.BlackBerry.com/T5/native-development/touch-event-handling-in-CPP/TD-p/3027043Third, you asked to simulate a key event in this thread I made.
Now, this isn't what you want, you want to simulate a click on a button.
I'll let someone else answer that one.

Problem with the ENTER_FRAME event from a loaded mc
I have a UILoader on the main timeline, then I have to load an external mc with an event ENTER_FRAME inside. When I insert something else, I found that the ENTER_FRAME event still works. Why he is not credited with the mc?
This is as3. all streams, intervals and events which are not dependent on the interaction of the mouse are running.
If you publish to fp 10, you can use the class loader and unloadAndStop(). otherwise, you must stop explicitly all fumes, etc. before unloading.

initialize the PostProcess event handler
Hello world
We develop a PostProcess event handler that loads a choice list values and to do a calculation based on the values of research and the parameters passed.
The Manager will have to face a lot of events, we are a little worried that the execution could get affected too (despite the asynchronous nature of the handlers).
Is it possible to precompute for example loading of research (which is always the same) and other calculations in an initialize() method so that the Manager is not obliged to all over again for each event?
Thanks for your help in advance!
To use the search in initialize the first you must instantiate full LookupOperation API to initialize and create a global variable to use the value during the life cycle of the event handler
It is not recommended "global variables should not initialize in this method.
Initialize method will be called only once during the event handlers loading, IE every time u start the server.
The object created in the initialize method will still be in memory. It depends on the size of your list of choices.
If it contains huge data not recommend you store it in the initialize method. As it will eat your memory.

How to use the zone with the calendar events settings?
After looking through the questions in the time zones, scheduling and synchronization, I still can't my Palm Centro to exploit the way I think it should.
I have a Verizon Centro, use Windows XP with Outlook and Hotsync synchronization manager 7.02 via a USB cable. I do not use Palm Desktop.
I expect events to pass the time in the calendar when I change the time zone, but they did not.
I am preparing for a trip. I enter several events in MS Outlook placing events occur in a different time zone in my calendar at the same time the event happen in my timezone (NY). For example, a meeting of 9-10 am in Los Angeles is put in my calendar to outlook MS as 12-1 PM on the day of the meeting. Then I have synced with my Centro and Outlook for New York time zone. The Centro is set automatically update Date, time, area of the network in New York. The event of the meeting appears as 12-1 PM the correct day.
Then I turn off the Centro phone (IE unplug the Verizon network), change the update time to 'Nothing' - is to say fully manual, change the time zone in Los Angeles and set the time to the exact time in Los Angeles. I expect the meeting to 9-10 AM in my Centro calendar, but it's not! I have try other combinations - let the time on the Date and the automatic time update and change the time zone in Los Angeles, etc.. I think I've tried all combinations. Overall, I leave the Centro phone out of the Verizon network. I can not get the meeting to change his time in the new time zone.
What's the trick? What did I miss?
You might ask why I'm trying this with the phone turned off - it's because I'm really much further that THE and in a GSM network where I will simply use the Center as a PDA.
All advice appreciated.
thepoeta-
Thanks for the reply.
In fact my preference was not established "new events use time zones."
Meanwhile, I had loaded all the applointments of Outlook, about 20 of them,
thinking that I would just manually move along the way.
I'll play with time zone preference, but,.
is it possible to identify the existing appointments in the
Palm as belonging to a time zone that is different, just by using the Palm Centro?
Thank you

Get the user that is executing Action in the Validation event handler
I know you can get UserLogin actor using ContextManager.
I would like to know if there is another for the user who executes the action (the actor) in a validation event handler.
Ideally I'd like the usr_key of the actor.
using the AuthenticatedSelfService api you can do. There is a method

Is it possible to set up the click event handler of reflow
In my view, does not reflow in click events/actions.
Example: I want to hide a rectangle at the click of a button and show it when you click on another. I want to do it on the same page and not imitate this action by loading another page with hidden rectangle.
Hi Sujit-
You are right. Reflow has support for the stationary, active flight and States of implementing at the point, but not clicking. To accomplish what you're looking for, you probably want to add javascript using another tool (Dreamweaver, cleats or one other editor) after you're done with the design of reflow.
I hope that helps and thanks for the use of reflow.

Strange problem with the keyboard event listener
I have a full screen touch app. To close the application, I set an event listener on keyboard for the key "0". I don't want the press user due to some restrictions Alt + F4 key combination. Problems begin when the application loses focus. Here's the code;
protected function onComplete(event:FlexEvent):void
{this.setFocus ();
this.addEventListener (KeyboardEvent.KEY_DOWN, trapKeys, true, 0, true);}
private void trapKeys(e:KeyboardEvent):void {}
If (e.keyCode == 96) {}
This.Close ();
}
Else if (e.keyCode == 48) {}
This.Close ();
}
}When the user change the screen to a different with Alt + TAB application, or any other combination of keys flex app loses focus and does not work when he turns back to my app "0". How can I solve this problem?
Thanks in advance.
Hi, Ahmed.
I have absolutely no problem with the solution you are trying to set up - you use mode full-screen interactive mode of keyboard?
Please consider:
on full add keyboard listener
protected function applicationCompleteHandler(event:FlexEvent):void
{
this.stage.addEventListener (KeyboardEvent.KEY_DOWN, trapKeys);
};
//
protected function applicationActivateHandler(event:AIREvent):void
{
If (this.stage)
{
switch the State to display full-screen when activated
If (this.stage.displayState! = StageDisplayState.FULL_SCREEN_INTERACTIVE)
{
this.stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
};
};
};
//
private var exitHandled:Boolean = false;
on NUMBER_0 | NUMPAD_0 exit-close
protected function trapKeys(event:KeyboardEvent):void
{
If ((event.keyCode is Keyboard.NUMBER_0
|| event.keyCode is Keyboard.NUMPAD_0)
(& this.exitHandled == false)
{
exitHandled = true;
this.stage.removeEventListener (KeyboardEvent.KEY_DOWN, trapKeys);
This.Close ();
};
}
(Note: applicaton of the events 'applicatonComplete' and "applicationActivate" are routed to over managers)
Kind regards

Cannot find the appropriate event handler
In the following code, I create 5 paintings where each canvas behaves like a button. Each canvas contains a text field and each canvas is movable. I want to trigger an event when the user drags on the side of the canvas, but on the contrary it is triggered as soon as I roll on the text field. You will see what I mean if you click on the text, and then drag the text to the side. It will trigger a trace.
It is very important that I have only to raise an event when I drag the canvas, not the text. Is there an event handler that will make thios for me?
Thank you!

GUI - how to block the execution of the parent event handler
Hello
IM learning flex, I did my first http://www.narutogis.appspot.com/ app and have some problems with the events of the controls.
my application is composed of canvas (as a parent) + 4 buttons + image (svg) and now:
- When I click on one of the 4 buttons as their 'click on' events are triggered, but after that it also runs 'click' event of the canvas parent. I don't want this feature can I block sort of parent controls event handlers. SImple click on the button must execute only the button ' click on ' event, nothing more
- When I click on the image it won't run "click event" canvas parent (reverse situation to that at the top) by clicking on the Image cntrol must execute the 'click' event Image and also parent canvas 'click' event
You probably need stopImmediatePropagation()

Communication with the main movie off external class
Hello
Hello, after recognizing that all my problems are as a result of the problem, I just start with AS3, having a litte experience with AS2 and common OOP. So, I try to understand the concept of AS3 on this level.
My problems are mainly in the defined direction how outwardly objects communicate with the main movie.
For example:
(1) can I call a DisplayObject instance out of an external class, if this DisplayObject is defined and added to the display list in the MainMovie?
2) can MovieClipObjects instance within a table, which works like an instance variable? I think that will cause trouble in the cascade of display list:
{should be corner braces: class.} MovieClips {i} = new MovieClip(); -> root.class.MovieClips {1} Point separates it levels in the display list, but also object and attribute.
Thank you
the debugger does not recognize this error message?
and if you want to clear the memory occupied by mc when you use:
var a: Array = [];
var mc:MovieClip = new MovieClip();
a [0] = mc;
use:
If it was added, remove the mc of the displaylist. remove all listeners and other references if there is.
a [0] = null; or a.shift (), if you do not have null in an array element. Use a.splice (i, 1), if you used a [i] = mc;
MC = null;

Rank Selector - how to set the onclick event handler?
I have a set of master-detail forms and would like to respond to the onclick event of the line selector. When I go on the line selector column attributes I don't see anywhere to set the onclick event.
The other elements of tabular presentation have a field 'Attributes of the element' that I use usually, but not line selector. I just missing something?
I'm open to alternatives as well. The reality is, however, I do not need anything either complicated or sophisticated. When the user clicks on the box I collect data from the current row and initiate an AJAX call. I have to submit the page, etc.
Thank you
BrentI think the only way to do this is to use the package apex_item like this:

Add dynamically with the click event.
I introduce several add button programmatically. I have sucessfully Add button but I can't able to get the button click event everything. I always click the last button added.
Event for all I want to separately, click the button.
I use this code for the Add button.
ComponentDefinition { id: mComponentDefinitionSubmitButton Button { id: mButtonID horizontalAlignment: HorizontalAlignment.Center onClicked: { //My Click code. Always detect last button. } } },
var mButton = mComponentDefinitionSubmitButton.createObject(); mButton.text = qsTr(title) mContainerButton.add(mButton)
I did with signal...
function checkClick(button) { console.debug("click..."+ button); } attachedObjects: [ ComponentDefinition { id: mComponentDefinitionSubmitButton Button { id: mButtonID signal click(variant text); horizontalAlignment: HorizontalAlignment.Center onClicked: { click(mButtonID.text); } } } ] ---------------------------------------------------------------- var mButton = mComponentDefinitionSubmitButton.createObject(); mButton.text = qsTr("Button"); mButton.click.connect(checkClick); btnContainer.add(mButton);
