ActionScript 2.0 :: Tree View - Adding Mouse Events To Handle Links
Mar 4, 2010
I'm trying to recreate a UI for an application that my company makes in order to create an in-depth training companion to the application. One of the features is a weird tree view that works quite different from any tree view component I've ever seen, so I decided to create my own version of it as the Flash AS2 Tree Component doesn't have the functionality, and I haven't found any Tree Component for sale or download that works like that either. At first glance it seems like a standard Tree, except that it behaves differently if you click on the icon for each node than if you click on the label.
Some labels are links, some nodes can have 2 different labels, each with their own link, and most nodes have a second label underneath the label next to the icon (these don't have events assigned to them; they're just a quick way to view information). So anyway, I set up an XML file with all the information that I need (the easy part), but populating the whole thing, making sure each subnode can properly exist within each parentnode while allowing me to open and close them has been a real challenge.
Basically, I decided to use a whole bunch of loops to go through the nodes in the XML, but my lack of experience in using them is kicking my rear end. Basically, I need some code that can evaluate all the nodes in the XML and sort them within the proper hierarchies and then create all the clips in the stage to add the mouse events for opening, closing, and handling the links (which do not direct to the same event as when the icon next to that link is clicked).
I want to handle the mouseevents for all the sprites on the stage including the one those are hidden behind (or overlapped or occluded) and the main condition is that I want to handle the occluded sprite (that hidden behind other sprite). example, say I have sprite1 and sprite2 on stage and I want to start drag whenever i click on the sprite and stop drag after another click.
This can be done easily, but the problem and my main requirement is that if I drag the sprite1 and drop it exactly on top of the sprite2 then sprite2 will be hidden behind the sprite1 I wont be able to drag the sprite2 without moving the sprite1 first. if you have played zynga's empires and allais game on facebook, it is handled seperatly, it is how it works in that game, the mouse event is triggered on the sprite behind the overlapping sprite, if you have two sprites overlapping one sprite than the mouse event is triggered on the sprite which is last and not the one in front irrespective of whether there is only one sprite overlapping or two or three and this happens to irregular shaped sprites (not just rectangles)
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.
I am loading an external SWF using the Loader class, and adding it to the stage with addChild.When trying to add a mouse click event listener to the MovieClip, using addEventListener, nothing happens, the event never fires.Is there a specific way to add listeners to externally loaded movie clips?My code looks somewhat like this:
var target:MovieClip = assets["screensaver"] as MovieClip; target.root.addEventListener(MouseEvent.CLICK, onClickScreenSaver, true); addChild(target);
The target shows up on the display, but the CLICK event is completely ignored.
I am not sure if it possible or what would be the best way to archive the following in Adobe Flex 4 (I am also fine with Flex 3). I need some kind of a tree view, but the items should be placed like a tree from top to down and not like it is done in the treeview implementation of the Flex framework. To make it more clear here an simple "graphic":
I've spend hours searching for a way to put one paragraph of text in one tree node in Adobe flex. How can I do it? I created a simple tree view but the text is cut after the right border.
So I tried to create a tree renderer. In the renderer I specified width=100 and the text wrapped. But the height of the nodes was not being calculated properly, so the text over consecutive nodes overlapped and got messed.
does anyone knows how i could just eliminate the folder icon of a tree control and display only the leaf? supposing i have an xml structure looking this :
I'm developing an AIR application with Flash Builder 4 Beta 2 (nightly SDK) an am not using a framework like mate. I have a couple of views and components in my application. An outline might look like this:
In ACE Flex 3 , there is a topic "Handle Framework Events". Any document which lists all the 'required' framework events for ACE test? So I could know what are "framework" events and will focus on them.
in Adobe tutorials, they suggest to create a class to handle the events (see below the copy/pasted code, and link to page).I was wondering if I have to handle all events with the function handleAllEvents, using if statements to check if the target is the one I want, and the event is the one I want.i.e. if (event.type=="click") && (event.currentTarget == "myId")Should I have a list of ifs (for each target and each event type ?)[code]
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;
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.
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).
I have numerous objects, many of them are stored within other objects (and overlap in physical space). As I zoom into an object, it begins to fade away. At the moment it begins to fade, I load in the child object (or create a child object if one doesn't exist). I want to turn off the parent object's ability to respond to most events. The exception is the scroll wheel, which needs to be sent to both objects simultaneously so that the parent can continue to fade out as I zoom farther in. Try as I might, I can't find a way to tell Flex "hey, for right now dispatch these types of events ONLY to this object." I either end up with event dispatch stack overflows from trying to manually redirect the events, or I get events that don't activate at the correct time or on the correct object. What can I do?
I've got a couple trees that I allow a user to drag and drop from one to another, works great except one apparent limitation. I'm picking up where they drop it in the list and adding it to the dataProvider manually. The user can drop it everywhere except after the last child of any particular node it seems, since it reads that position as being between the node and it's next sibling.
It seems the best way to deal with this is to add something like a dummy leaf so the user has something to drop the item in front of. I don't want this leaf in the dataProvider, so is it possible to add a leaf (or a folder) to the tree without adding it to the dataProvider?
I currently am trying to add a custom class which subclasses UIComponent to both a tree and a canvas, but when I try to re-order the tree by dragging I get this error:[code]When I do not add the UIComponent to the canvas, this error does not occur, anyone have any knowledge as to why this happens?
Just curious, If i nest a movieclip inside of another movieclip, and the nested movieclip is attached to a custom class. And that custom class has a Event.ENTER_FRAME listener. when I destroy the container movieclip, will flash get rid of the event listeners inside of nested movieclip's custom class ?
May seem like a silly question but flash has a tendency of not killing listeners along with the movieclip itself once it is removed from the stage(this is if your apply the movieclip via addChild). and its a hastle when things get too complex. My solution was to create a single loop for all my objects. Now ive come to a point where I am probably going to have to nest some movieclips inside of another so the position of the nested movieclip stays relative. the parent movieclip will be rotating and scaling so I rather nest it. But I got to know how flash handles moveiclips that are nested into a parent movieclip and has enter frame listeners.
I've stumbled across a very interesting tutorialBut, I've noticed a little detail. When you click on the big image of the finished example on the first page of tutorial, it acts like a link. When I have downloaded finished .fla source, links are nicely written in the images.xml file, but the links in the .fla file don't work.
In a project i'm doing I have a custom cursor, using the start drag command and mouse.hide. the issue being that the movieclip being dragged is blocking the mouse from initiation mouse events properly.
I have a movie clip I am using as a button (instance name btn1) and I added an event listener to it (using the following line): btn1.addEventListener(MouseEvent.MOUSE_OVER, animate1); the function "animate1" triggers some small animation when the mouse is over the movieclip. my problem is that the animation is triggered both on mouse over and mouse out events.
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)
I have a menu drawer at the edge of the screen that shows when the user rolls the mouse over it, but if the user overshoots it an moves the cursor slightly outside the browser window this is unfortunenatly registered as a mouse out.
I want to stop this by using event.MOUSE_LEAVE, but i need to use it as a condition not to triger a "leaveHandler".
