Flash :: DisplayObjectContainer Into Flex Component?
Apr 29, 2011
I'm trying to get a class file from Flash into Builder.Everything in that class sits inside a Sprite called mainContainer. Now I'm trying to get that `mainContainer' which hold the graphics for the class into a Flex Application.This is proving to be a problem as their are many various ways of doing it (it seems going by numerous Google searches).First off I declare an MXML Canvas with an Image inside it (as I read would work):
I have a display object container and I am trying to add a paste event to it. But the event is not being registered. The documentation at liveDocs mentions that classes that derive from Interactive objects can dispatch paste event but I dont understand why it wouldnt work for me.
I would like to know the internals of that method, in other words what exactly happens when I call that method. If someone can explian it with a list 1,2,3... would be great. including events..
in ActionScript 3, if I loop through the children of a movie clip, it will return a DisplayObjectContainer, which is a list of DisplayObjects. However, the AS3 typeof cannot identify MovieClip as MovieClip is now an object, instead of a data type. How can I correctly identify MovieClip?I found 3 solutions online: First set the MovieClip name to a specific name, then in the iterate process, check the name of children using child.name.indexOf("specificName") > -1
Solution 2:use child.hasOwnProperty("numChildren") to identify a MovieClip
Solution 3: use 3rd party plug-in like FlashDevelop
A DisplayObjectContainer's dimensions change based on its contents.
That can be a LOT of contents, many of them with visible = false or masked, thus making them hidden. Is there a way to get only the visible contents of a DisplayObjectContainer similar to a TextField has the textHeight property, which gives you the exact dimension of what you see on-screen.
I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
I'm creating an object that's only purpose is to hold a few other display objects, so all I need is a super class that can hold display objects. I don't want to use the sprite class because it has so many functions and properties that I don't need. if I can't use DisplayObjectContainer as a base class then what class should I use?
I am converting a DisplayObjectContainer as a Bitmap using BitmapData.The DisplayObjectContainer has many DisplayObjects. I want to exclude few DisplayObjects while i tranform into Bitmap.Therefore the bitmap should not have that particular displayobjects alone.
Code: import flash.display.Sprite; var sp1:Sprite = new Sprite( ); var sp2_1:Sprite = new Sprite( );
[Code]....
I'd assume from this that there is no correcting done for children with the same name being added to the same parent. I ask this question because I'm creating a structure that needs to mimic the display list and I'd like to keep behavior consistent.
Another question: I'd assume internally the children are saved in something similar to a Dictionary object, does anyone know if this is true? And then getChildByName simply does a foreach loop and returns the first match on a name?
is it possible to clip children that are part of a DisplayObjectContainer? If I have a parent object with size x 100, y 100, width 100, height 100 and a child that has the coordinates x -50, y -50, width 100, height 100, I can still see the full child staying at x 50, y 50, but I want the child to be cut off by the parent.
I have a class which will contain exactly one child, no more, no less, and other classes are not allowed to change that fact.
I could throw error messages every time a child is added or removed by overriding the default properties, but I don't want the object to be treated as if it were a DisplayObjectContainer.
I want it to look like only a DisplayObject, yet I still want to add a child to it in private.
I'm working on a class that let's you use "addChild" to add children to it. In all aspects, it's treated like a regular class, the only difference is that it doesn't really add them. It only draws the BitmapData of them and displays that, which doesn't make a huge difference for the user, but might make a difference for performance, at least the way I am planning to make it.
Now, if users add a regular old Sprite or other DisiplayObject to the container, I have overridden the function to draw the BitmapData of the item, and store the item in an array.The problem is, if the user want to do something like "sprite1.parent", since the Sprite technically isn't on the display list, the parent property will be null. I can't override the passed in sprite's properties, right? Is there any way around this?
var sp:Sprite = new Sprite(); trace( sp.width ); // the result will be 0 var mc:DefinedMC = new DefinedMC(); // assume that DefinedMC is derived from movie clip, and the width of mc is 100 sp.addChild(mc); trace( ap.width ); // the result will be 100 [code].....
so the size of an instance of Sprite is affected by its children.is there any class derived from DisplayObjectContainer whose size is not affected by its children, or is there any method that could make the size of Sprite is not affected by its children.
I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
I would like to bind two components with out binding and which resides in different MXML.for eg: A.mxml has textinput and B.mxml has a combobox when choose one item in B.mxml selected item should be display in A.mxml textinput.
I'd like to use a button within a component to remove it. So, you click it and the component is gone. But, I haven't figured out how you reference the component from within the component. What should I put in click=""?
A Flex components values are initlized by init methord. In an application flow, How to refresh a mxml component data value ; as init is callled at the start up it self only.
eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )
I am using flash builder 4 to run sample application from "Getting Started with FLEX 3", but the code can't run because there is one place that FB4 can't resolve, I guess this is because the library has been obsolete but after a tons of search I can't find the solution.
I am using Flash CS4 and would like to use the available browser component in AIR. However, any information I have found online uses Flex to embed this. Is it available in Flash? I was assuming it was part of the AIR architecture, so it would be able to be used in either, but it doesn't seem so.
I am creating a custom component in Flex with extends the BorderContainer class, and I would like to be able to place additional content within the tagset when I use it in my main application, like this:
<components:CustomComponent title="Hello"> <s:Label text="If you have one enter it below:"/> <mx:Spacer height="15" />
[Code]....
This works just fine, except that my component definition had some additional things inside of it, such as a <s:Label/> and styling, which is replaced by the content within the tagset above when I go to use it.
If I do not put anything within the tagset, the content that was originally in the component is not replaced.
Is there a way that I can simply append additional content inside of the component when I go to use it, instead of it being replaced each time?
I have used Flash to make skins, which I import and apply to Flex components.But how can I create a component in Flash, with properties and methods. And make it able to be added to the displayList in a Flex app?I installed the Flex component kit for flash. Created my component in flash (it extends MovieClip). Did Command->Convert to flex Component, did File->Published, which gave me a .swc, dropped the .sec file into my Flex project. Now when I create a new var the class "FlashFlexComponentTest" pops up in the new class hint box, so flex sees it. But afterwards I get the error: [code]I added the .swc via project build path -> add SWC.I no longer have a compile-time error but I am getting a runtime error:[code]
I have an ActiveX componenet that displays some data from external systems (scada) and I'd like to embed it in my Flex web application's frontend (displayed in browser).
I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?
