ActionScript 3.0 :: Mouse Events Lost In UIComponent?

Nov 1, 2008

I have an AS 3 class that extends UIComponent. In that class I dynamically add several sprites, that are also AS 3 classes that
extend from Sprite.So, in my UIComponent extended class, I added these listeners:

this.addEventListener(MouseEvent.MOUSE_DOWN,mouseDownHandler);
this.addEventListener(MouseEvent.MOUSE_MOVE,onMouseMoveHandler);
this.addEventListener(MouseEvent.MOUSE_UP,mouseUpHandler);

I added trace messages inside each of these event handler functions. The problem is that, whenever I try to dispatch these events starting from one of the children sprites from the UIComponent (let's say I click one of the sprites and the mouseDown event starts) the sequence works perfect. However when I try to do the same in the "blank" area of the UIComponent (which is just a

graphics.beginFill(0xffffff);
graphics.drawRect(0,0,this.width,this.height);
.graphics.endFill();) nothing happens. The events are never
"listen" by the UIComponent.

Actually if I run the app and click on the white area, the trace messages are ok, it triggers the mouseDown event, but only one time. I a click again, nothing happens.I tried adding another sprite, to have this one holding all the other sprites, and tried to add the listeners to it...same effect. I can't get that UIComponent to listen and react, only it's children sprites...

What I'm trying to implement at the end is a multiple drag selection of the children items of the UIComponent, but I have to be able to start the drag selection from any point in the screen.

Flash :: Getting Mouse Events From UIComponent Child In A Spark View Does Not Work

Nov 3, 2011

I have a custom UIComponent that is basically just this:

public class WhiteboardUIComponent extends UIComponent
{
public function WhiteboardUIComponent() {
super();

[Code]....

This is absolutely the simplest that I could make the example. The s:View is gobbling up my mouse events - if I add a handler in the MXML to the View, I get mouse events just fine. When adding a handler programmatically in my subclass' constructor, I get nothing. I thought maybe the layout was wrong, so I explicitly set the dimensions of my UIComponent and stuck it in a border just to be sure it was where it was supposed to be - same deal.

Missing ROLL_OVER Events - Get Lost With Hyper-active Users?

May 18, 2009

I've got 5 groups of 6 nav buttons. We need a ton of navigation in a very small stage size, so, to reduce screen clutter each of these nav groups is a mc with the nav buttons out of frame. On ROLL_OVER a 15 frame tween in the mc slides the buttons in, on ROLL_OUT a 15 frame tween slides the buttons out.

If the user is slow and deliberate with the mouse everything works fine but it's easy to confuse the event handlers. If the user moves the mouse around quickly you can arrive at a point where the mouse is hovering over the menu but the required ROLL_OVER event to show the menu was never triggered. This is much easier to see in action than to describe (note that only the star one tab (top left) is coded): [URL]

ActionScript 3.0 :: Control Mouse Events With Other Mouse Events?

Feb 12, 2012

Right now all the sounds (78 of them) on my guitar play using the roll_over event but that doesn't give the user much control over what sound is played.
 
The actionscript im using to play my sounds is this;
 
for(var i:uint = 0; i < buttonArray.length; i++){
buttonArray[i].addEventListener(MouseEvent.ROLL_OVER, buttonRolledOver);
}

[Code]....
 
What i want to do is only play a sound with the roll_over event when the left click is held down.

Actionscript 3 :: Iphone - Touch Events Vs Mouse Click Events?

Jan 11, 2012

Just wanted to ask if there is any advantage for either using mouse click event or touch tap events, when writing apps for mobiles or tablets (for the iphone especially)?

I know that both of them should work fine, but in term of performance, is anyone better? Are there any things I should be aware of when choosing either?

By the way am using actionscript3 to implement the app.

ActionScript 3.0 :: Mixing Stage Mouse Events And Children Events?

Sep 30, 2009

I have an animation that I want to start when clicking on the flash window. However, I've also have some buttons on the stage. If I add an event listener for MouseEvent.CLICK on the stage, then it 'eats up' the events and the buttons don't work.

I've tried some tricks, by adding some invisible buttons on top of the real ones, and use the MOUSE_OVER event to selectively enable/disable the mouseEnabled flag for the stage, but didn't work because it complains that the property or method doesn't exist (which I find odd).

ActionScript 3.0 :: Mouse Events Fail To Trigger If Mouse Move Too Fast?

Nov 18, 2009

It has been awhile since I have worked in flash.Right now I am working on something where I would like a panel to disappear when someone mouses off the stage.stage.addEventListener(Event.MOUSE_LEAVE, leaveHandler); It usually works fine but if I move my mouse really fast it doesn't fire. I have also tried the same thing using a custom invisible button that surounds the perimeter of the stage and I have tried ROLL_OVER and MOUSE_OVERand again, if I do it too fast my event doesn't fire (I am using trace)I can't find anything on the net about this - is this typical of flash that if you move your mouse too fast you break it? Do I need to increase my frame rate (I would really rather not because I have perfectly timed animations - I am at 30 frames per second)

Flex :: Mouse-event - Using 2 Distinct Mouse Events?

Mar 14, 2011

I am looking to provide some UI functionality using the mouse- I have two distinct UI events to be achieved via mouse

a) change value
b) delete object

I don't seem to have sufficient mouseclick events for both. I am avoiding using the right click as it has some default options(whose signing off will affect the whole project- not just this). I have mouse click used for change value- how do I use the doubleclick as the single-click events seems to get invoked prior?

I see that it is running and that it has the correct hights but I got the feeling that it doesn't show up with this hights. If I trace I see the width and height is 200 X 200 but there is still nothing visible in my component.

ActionScript 3.0 :: Some MCs Not Detecting Mouse Events?

May 29, 2011

I've just hit a really strange bug with a program I'm creating. The program allows the user to add shapes (currently all squares: SmallThing, MediumThing and LargeThing) to an area of the screen, then drag them about by clicking and draging using the mouse. Pretty simple. Unfortunately, the code seems to be failing for the smaller shapes (they're not THAT small, currently the smallest shape is 32 x 32) which are not generating mouse events at all. I have used trace statements to verify this. I am having a few issues with the larger shapes ocassionally not registering mouse up events, but I can live with this - the main issue is with the small shapes not being moveable.

All the shapes are descended from the same super class, and have the same event listeners added to them when they are created.
 
Here are the relevant functions in my Screen class. It's all pretty basic code so I really can't see what the problem is.

Flash :: Safari And Mouse Events?

Sep 14, 2011

i have a question about the mouse down / mouse move events in Flash. I've developed a small intreractive that requires mouse co-ordinates to be captured when the mouse is down and when the mouse is moved anywhere on the screen. It was working fine like this until recently when I checked my interactive in Safari and it no longer recieves mouse co-ordinate information when the mouse cursor leaves the Flash interactive stage area.However, it still works fine in Firefox. Is there anything I can do to get this functionality back when using it in Safari?

Scroll Panes And Mouse Events

May 29, 2011

I have another problem with my scroll pane. I now have a bunch of Loader objects that are used to display thumbnail images in a scrollpane. I want to add a MouseEvent.ROLL_OVER event so that when I a person rolls over an image there will be some buttons displayed, IE a remove button so the user can delete an image from the gallery. However my ROLL_OVER and ROLL_OUT events are firing like CRAZY when I place my mouse over a picture. Right now I have the roll over and roll out events set to just hide the image (so I know that it's working). But all that happens is the image flashes....

I am making a custom scrolling list (smart phone like) in actionscript 3 and have the parent contianer catch mouseEvents for MOUSE_UP and MOUSE_ DOWN.Sometimes the mouse up event is missed, maybe one in 20. Does this happen if the events fire to rapidly? I do not want to use the MOUSE_ CLICK event beacuse if the mouse pointer moved at all I want the list to scroll and not catch a Click event.[code]Can I somehow ensure that all events are fired?Or if not can I somehow get mouse button states directly from flash? Not via the mouse event object, but in onEnterFrame().

ActionScript 3.0 :: Trigger To Events With Mouse?

Dec 10, 2010

I am trying to trigger two events with a mouse click. I have a filmstrip MC with 6 images (shows three until you click one of the buttons) and I have a left and right arrow in its own MC these are both in the main MC and the action script is located in the main on layer called actions. My code is as follows�

//event listener for the filmstrip left and right navigation
leftRight_MC.leftBtn.addEventListener (MouseEvent.CLICK, leftNav);
function leftNav (event:MouseEvent):void

[code]....

The desired effect is to show the button which will get the filmstripMC to move as an active button and the other one as dead.I have tried an eventListener in the leftRight_MC to trigger the different states and it is buggy. It will go to the left but not to the right.

ActionScript 3.0 :: Mouse Events On MCs With Filters?

i have a series of MCs with glow filters applied to them that grow in size when moused over. however when they are "moused over"/as the mouse crosses the "borders" of the shapes to gain focus the "growing" animation is not smooth, it like jerks around a bit as the mouse crosses the borders before the animation actually happens. i set all of the MC's to mouseChildren=false so i know it has something to do with the effect. it seems that happens with most of the effects i've tried.

does anyone know how to make the mouse NOT interact with the effect/filter?

ActionScript 3.0 :: Ignore Certain Mouse Events?

I have a solid movie clip that is overlayed with a grid movie clip. Actually they are sprites. The solid sprite underneath has a MOUSE_OVER event. I have set mouseChildren and mouseEnabled on the grid sprite to false so that it receives no events. The problem is that when I go over a grid line the sprite underneate still receives the MOUSE_OUT and then the MOUSE_OVER event again. Is there anyway to make the grid completely transparent to the mouse so that it won't trigger the MOUSE_OUT and MOUSE_OVEr events for the sprite underneath over and over?
