Please assist me with the mouse over event on this clip
I'm trying to make a notices box in flash that slides over to the right and opens on mouse over.
I've done the necessary actionscripting I feel, yet the clip doesnt quite behave the way it should
Can someone please help me
I'm including a link to download the .fla file as it won't let me attach it here with this post saying " The content type of this attachment is not allowed. "

in Leopard Spotlight used to show you the path /location of a file when you stayed with the mouse over the result. As sometimes I just look for the location of a file not to open it like a mp3 file. It would be nice to have a opiton in spotlight to contorl or right click a file and then give the option to say show in finder. that only works when you have your results show up in finder first and takes a bit longer. or maybe in the new prieview window to show the loaation or give you opitons what to do with the file
Just an idea to spotlight even betterWhen you hover over a file in spotlight list (or select with up/down arrow) you can also hit command-R to open the folder where the file is located. Kind of like 'Show Original' for aliases.
But yeah, Apple really needs to just show the directory path on the hover pop-up by default. Obviously, when you do a search you'll most likely get several files with the same name - we need to see the locations to tell them apart. One of the main reasons to do a file search is to simply find out 'where the file is located' - not necessarily open the file. Seems pretty shortsighted to not show the file location in the search result. -
One more nugget: Chart zoom with the "Mouse Over" effect
Hello all.
Just read my signature first, it might explain a lot. I do not intend to compete with Darren and I don't think this "nugget" (at least it supposed to be one) will amaze any of the LV veterans and this forum is rich of them. But maybe it will bring some new ideas to some of you or maybe it will be useful for some LV beginners (like me). It is very likely, my code will have some lapses, but please be gentle pointing that out to me. If you feel a need, you can always optimize the code and develope it further. Just don't forget to share!
So back to the point.
I am developing a project using LV. In my program there is a waveform chart which has to show 4 plots. Depending on the length of the X Scale, it sometimes gets hard to see the plots clearly because of their density.So I decided that I need a tool, which would zoom the chart in. And this is what I have came up with after a few "Google" searches to check which part of the bike is already invented and also a bit of programming by myself.
Maybe you guys (at least the veterans) know the BetterVIEW Consulting LV example where they have implemented the Mouse Over effect. So a part of their example has been used in this tool and part of the credit must go to them. I thank them a lot
This tool uses a cluster and its property of visibility to show/hide the cluster depending on if the current position of the mouse cursor is in the desired range or not. The program also gets the image of the chart and returns the subset of the image. The subset is taken for the area arounf the mouse cursor. So if you move the mouse, the zoomed in area will also chage in response. After that, the subset of the image is zoomed in for better view.
The user might chage the zoom factor during the execution. Also it is possible to turn the zoom option On or Off if you don't wish to see it for the moment.
This is how the front panel looks like:
And this is the image of the block diagram (see the attached files for the vi, the VI Snippet tool distorts the code too much, so I haven't added it):
I haven't found anything the same in the forum. Yet I'm a newbie here and I don't have that much experience surfing it. If it wouldn't be something new (in the forum, not necessarily to some of you personally), just ignore the thread. I hope this was worth your time and your attention.
Good coding

While evaluating my code please have in mind that I am a LV novice. Therefore sometimes my code might violate some coding rules that I have to learn about myself. But how else could I do that...
Chart zoom with "Mouse Over" effect
Attachments:
Zoom.vi 198 KB
Mouse_pos.vi 20 KB
Check_pos.vi 18 KBVery nice Giedrius.
It takes guts to "step up to the chalk board" so I will do what i can to give you some ideas to think about. This is similar to the type of feedback I offer durring our in-house code reviews.
1) The floating property nodes outside the loop are not sequenced by wires so they could execute after the loop starts. Sometimes this could cause weird errors. Seq with the error cluster.
2) Property nodes can be re-sized so you can apply more than one property setting in the same call. Property node have to execute in the UI thread (which is single threaded) so using a single nodes will force a single context switch rather than one for each.
3) Setting the same property repeatedly in a loop just burns CPU. THe Scale min for both X an Y can be moved outside the loop ?
4) THe Wait Until Next ms" function does not get used in any of my code. It is not a way to get a fixed wait but rather a random wait. If you code completes 1 ms after the next multiple, the delay is double less 1 ms. If you have multiple loops using them and it f the delay for each are not unique prime numbers, then the "Wait until next ms multiple" is a good (cough cough) way of getting them all to wake up at the same time and fight for the CPU.
5)An Event Struture to monitor mouse enter/leave and mouse move (this would have to be a sepearte loop) is easier on the CPU than polling.
6) Is that math in the case to handle the Chart position on the FP? If so then using the property nodes for the chart to find its postion will let you code adapt to GUI changes.
7) Right to left wires are not well recieved.
8) A Bundle by Name is prefered over a "Bundle" since it is self documenting. I know the Picture function so I can see that is the rectangle you are specifying but reader not famliar with that function would not be able to "READ" the code without poking at it.
9) THe event structure would also help with setting the Zoom factor. Only poke it when you have to.
That is all that comes to mind at the moment.
Again thank you!

Mouse Over event not dispatching properly.
Hi,
I am working on a scroll for iPhone, in which I'm using touch scrolling, it is working fine with less number of list items, but when I increases the nuber of items in scroll list, the mouse over event not propogates properly, I mean to say those events are overlapping due to some extra memory issue, can any one have any idea about it.
I'm pasting code for your reference :
public function IPhoneScroll( pContent:DisplayObjectContainer, pStage:Stage ) {
_stage = pStage;
_myScrollElement = pContent;
_canvasHeight = _myScrollElement.height;
start();
// add handlers
_myScrollElement.addEventListener(MouseEvent.MOUSE_DOWN, on_mouse_down);
_myScrollElement.addEventListener(Event.ENTER_FRAME, on_enter_frame);
private function on_enter_frame(e:Event):void {
if ( started )
// decay the velocity
if(_mouseDown) _velocity *= MOUSE_DOWN_DECAY;
else _velocity *= DECAY;
// if not mouse down, then move the element with the velocity
if (!_mouseDown)
var textHeight:Number = _myScrollElement.height;
var y:Number = _myScrollElement.y;
var bouncing:Number = 0;
// calculate a bouncing when the text moves over the canvas size
if (y > 0 || textHeight <= _canvasHeight) // textHeight <= _canvasHeight => when the item is smaller than the stage.height, align to the top
bouncing = -y * BOUNCING_SPRINGESS;
}else if( y + textHeight < _canvasHeight){
bouncing = (_canvasHeight - textHeight - y) * BOUNCING_SPRINGESS;
_myScrollElement.y = y + _velocity + bouncing;
// when mouse button up
private function on_mouse_down(e:MouseEvent):void
if (!_mouseDown)
// get some initial properties
_mouseDownPoint = new Point(e.stageX, e.stageY);
_lastMouseDownPoint = new Point(e.stageX, e.stageY);
_mouseDown = true;
_mouseDownY = _myScrollElement.y;
// add some more mouse handlers
_stage.addEventListener(MouseEvent.MOUSE_UP, on_mouse_up);
_stage.addEventListener(MouseEvent.MOUSE_MOVE, on_mouse_move);
// when mouse is moving
private function on_mouse_move(e:MouseEvent):void
if (_mouseDown)
// update the element position
var point:Point = new Point(e.stageX, e.stageY);
_myScrollElement.y = _mouseDownY + (point.y - _mouseDownPoint.y);
// update the velocity
_velocity += ((point.y - _lastMouseDownPoint.y) * SPEED_SPRINGNESS);
_lastMouseDownPoint = point;
// clear everythign when mouse up
private function on_mouse_up(e:MouseEvent):void
if (_mouseDown)
_mouseDown = false;
_stage.removeEventListener(MouseEvent.MOUSE_UP, on_mouse_up);
_stage.removeEventListener(MouseEvent.MOUSE_MOVE, on_mouse_move);
public function release():void
_myScrollElement.removeEventListener(MouseEvent.MOUSE_DOWN, on_mouse_down);
_myScrollElement.removeEventListener(Event.ENTER_FRAME, on_enter_frame);
_myScrollElement = null;
The highlighted part is working properly for less items but not for more number of items, lets say 200 movieclips in scroll lists.
Please help me on this, thanks in advance.
VipulHello.
Look I have an idea, I donu2019t know if you already try it.
Please give the format that you want percentage, decimals etc...
In the Excel where the charts are being directed
Then redirect de chart to the same cells, these with the porpoise of refreshing
Now each serie have the format.
Please let me now what happen with these -
Mouse Over Event handling - Webdynpro
Hi,
We are working on a sample Webdynpro application. We want to show a pop up window on Mouse over of a control. Is this possible in WebDynpro? Do we have a handle for the mouse over event!?
Kindly help.
Best Regards,
Anushahi anusha,
If it is simply a tooltip that you would like to be displayed then there is a tooltip attribute that can be set when using the HTMLb controls, or the method setTooltip("my tooltip"); when using the APIs. If you need more of a mouse over event, then I would personally use standard HTML instead. You can use the same css classes that are used when creating HTMLb components so that the button would look the same, but it would be more under your own control
some code snippets are there in this link if you are using bsp.

Do precise sliders adjustments with the mouse wheel
I would like to be allowed to use the mouse wheel to move sliders in small increments/decrements. E.g. 1 by 1 for Recovery and Blacks and 100 by 100 for Temp in Develop module. To be also fast, I should just need to hover with the mouse over the slider, and then use the wheel (with no need to click). Leaving the mouse to use two hands and hit Alt+arrows just doesn't cut it.
Nicolas,
if you have to do a click at first to give them the focus, then you have to do a de-click afterwards as well or at least hit the enter key. Otherwise following shortcuts will be eventually misinterpreted because the focus still remains on the slider. -
Even with files I used to be able to see the download option with (Quicktime files) I do not see the option when I hover over it with the mouse.
Which add-ons do you have that say "incompatible with Firefox 5.0"?
Maybe something like download helper? You need to find an update for that add-on. -
Does Flash Engine supports "Mouse Over" events on an Android device with a mouse?
We built our custome Android on a Beagle Board. When we play a Flash content on WebKit, the flash does not respond to mouse over events.
When mouse pointer comes on an object with mouse over effect, nothing happends.
Can you confirm that there is Mouse Over support in Android 2.2 Flash Engine?
Thanks in AdvanceThanks for the link. Im just stuck on one issue right now. I
quickly noticed that the samples make use of mx.transitions.easing
as seen in the script below. How does Flash 8 address this?
myButton_btn.onRelease = function() {
tweenBall(mx.transitions.easing.Bounce.easeOut);
function tweenBall(easeType) {
var begin = 20;
var end = 380;
var time = 20;
var mc = ball_mc;
ballTween = new mx.transitions.Tween(mc, "_x", easeType,
begin, end, time); -
i just bought the monthly package of lightroom and photoshop cc. I can't seem to find it under the apps on creative cloud - can you please assist me with this.
You can right click the tab and choose "Close Tab" to close a tab.
Some menu entries are hidden by default and only appear if you use the keyboard to open the menu.
You can see the difference if you use Alt+F or Alt+B to open the "File" and "Bookmarks" menu and compare that to what you see if you use the mouse to open the menu after you have made the menu bar visible by pressing Alt or by pressing F10.
Press F10 or press and hold the Alt key down to bring up the "Menu Bar" temporarily. -
I accidentally quit my CC on my Macbook pro and now the cloud icon is grayed out and every time I hover over it with the mouse I get the spinning beach ball of death on the icon. I have no idea how to open it because when I use spotlight search to open it it gives me a message saying "Creative Cloud is not open anymore" help!
Since you didn't include any pertinent info such as the Mac model and OS version you are running, here is some general information:
Mac OS X: Gray screen appears during startup
Depending on which OS yours came with originally - and which OS you are now running - you would either need your original install disks - you can call Apple for replacements by giving them your serial number. Or you may be able to reinstall the OS by using recovery (again, depends on which model/which OS). -
I've developed a site using "web Page Make" I put a graphic on a page with a mouse over that morphs the graphic and plays a brief wave. I works with I.E but no go in FF 3.63.I am previewing this off a local networked drive. No problems with other net site with embedded audio do I need a certain add on etc. Can anyone offer some advice. Thanks
== This happened ==
Every time Firefox opened

Hello,
I have two objects. First object (1) has event listener
MOUSE_OVER. On this object is another object (2) without listener.
When I move with the mouse on second object, mouse over event on
object 1 is not dispatched. I don't know why. How can I do it ??
thanksIf both objects are in a VBox, with the second object (no
listener) overlapping the first object (has listener), when you
hover over second object, if you have a listener on the container
you should be able to see if the target for the event is the second
object and then take action.
This is because events first "cascade" down from the top of
the display list, through all containers until they reach the
target (targetting phase), and then they bubble back up to the top
of the display list (bubling phase). -
Tabs always "snap" when adjusting them with the mouse
As you can tell I am a new poster to this forum, and I am getting up to speed with Pages '09.
However, I am a long time user of all versions of AppleWorks, from ClarisWorks to AppleWorks, and I know a bit about them, okay.
Unfortunately, I find some things annoying with Pages '09, but please note that I also find the positives are well in advance of those, by miles or kilometers if you will.
As my subject suggests, when one is adjusting the tabs with the mouse, the tabs always snap to the closest whole number position of the ruler setting. I believe that this feature is wrongly implemented, especially if you don't have another option to over-ride it.
I know that I can fine tune the tabs using the Inspector and the Text tab settings for Tabs, but having to use this feature slows you down, A LOT!
This post is really just a way for me to "let off some steam," so to speak, as I know that there really isn't much that anyone can do about it, unless that this feature is reprogrammed.
So what about it Apple engineers, such a small feature, such a big time saver.
Much regards
Felix MacriI have to thank all the people who commented on this seemingly "small-time" item.
It would seem a bit unfair that such a solution would require that someone other that Apple would have figured it out and then posted it.
Seems like we are fending for ourselves here.
Maybe because this program is such a complex beast, that some of their features slipped through the cracks in regard to updating their documents.
Whatever.
We have the solution by someone's ingenuity. Viva the collective minds of the rest of us.
Much regards
