ActionScript3 :: Flex - Determine The Position Of An XML Instance In An XMLList?
Aug 11, 2009
What it says on the tin: I have an XMLList, and I want to find where in it a particular XML item falls. First index is good enough for my purposes. Note that I have no problem writing a function to do this by hand... but I was hoping that the API has something buried somewhere that'll do it for me. I didn't see it, though.
I've been wondering if it's possible to change the backend of the LLVM implementation from ARM to something else for instance C or C++? Currently Adobe uses a Actionscript3 frontend (which I can't currently find - closed source?) for the LLVM to produce iOS applications. I'm wondering why there isn't more options for other backends? Of course there are limitations to going this route, no loading of external swf files at runtime (to name just one), but the iOS applications seem to manage really well with this feat. I did find this pdf which talks about the AS3 LLVM frontend, but no guidance to where the code is or how to investigate... I just think it's a missed opportunity that Adobe are missing and wondered how much work it would be to do such a feat?
Is it possible to place object on stage with positions read from a CSS file?Basically what I want is to create themes for the application. As and when a different theme is selected, xy position, skins and colors of objects should get applied accordingly.How far its practical? If this is not practical could any one suggest a better way of applying theme
i am doing a searching algorithm, so let's say the path is from A to B to C and finally D (A->B->C->D) and it is represented in an array, such that path={"A", "B", "C", "D"}; how can i link these four elements to redim as instances on the desktop, such that i have four instances, named A, B, C, D, and also the line which connected to one of the each other, named AB, BC, CD.
for instance, how to set the color line AB, BC, CD? (the array always can be in different set of answers.) before that someone told me dont use the double quotation, but i think that's not working with my program, further more, i need to combine two elements, which represent the line connected to two ends.
I have an XMLList 'Keywords', which consists of about 30 elements. I want to count the number of unique keywords in the List, and how often they occur. Then display the top 3 most occuring keywords.
I have some movieclips like this one: game_mc.substage_mc.rightHand and inside the rightHand i have a thread_mc like this:
game_mc.substage_mc.rightHand.thread_mc
Ok so here is the thing, i need to access the thread.x and thread.y position related to the stage or substage_mc i donīt really care, but if i do this[code]...
Is there a way to determine the current position of the pen in a graphics display object. Something similar to what is discussed in this thread but for AS3?
In 90% of the example projects I see for ActionScript / Flex I notice the following two coding conventions: 1) private member variables with getters/setters start with an underscore as in "_credentials" and 2) interfaces start with the letter "I" as in "ISessionInfo" Coming from the Java world, I find both of these conventions unnecessary and annoying. I am about to start a new Flex project and was planning on NOT following these conventions unless they are truly are widespread, standard conventions in the Actionscript/Flex world.
For example if I was given the string "01/01/1980". How could I then get the current date, then figure out how old someone is, and then just return how many years old they are?
I saw a topic on this in C++ but i'm not to familiar with it, anyone know how this would be done in AS3?
edit: I think what i'm having the hardest time with is how I would break down the original brithday string i'm starting with into month, day, year vars
I have a UI component that, for various reasons, I have to construct programatically. The component is a table of radio buttons grouped by column.Right now, I'm constructing the column groups like so:
private function createGroupsForItemList(items: XMLList): void { for each (var item: XML in items) { var rbGroup: RadioButtonGroup = new RadioButtonGroup(); groups[item.@level.toString()] = rbGroup; } }
I'm trying to associate the RadioButton instances with the column groups like so:
private function createValueControl(item: XML): UIComponent { var control: RadioButton = new RadioButton(); control.label = "";
[code]...
I can see in the debugger that the control has an association to the group:
control.group == groups[item.@level.toString()]
However, I can see equally that the group does not know anything about the control:
group.radioButtons.length == 0
I imagine that this is because the setter for group in RadioButton is a dumb setter; all it does is copy to the variable, which doesn't do the magic that groupName does. However, I can't seem to find the value I should use to set the RadioButton.groupName property correctly.So, in short, I'm stumped on how to get these bits to talk to each other. How do I do this?
-- EDIT -- It turns out that I can have the groups created and associated simply by setting the groupName property, but I can't get at the group to set up a selection listener; the group is NULL immediately after the setting process, which means that the second line below throws the Flex equivalent of an NPE:
I've been trying to embed some svg files into an AS3 project using the Embed meta tag. For example:
[Code]...
However when displaying these files as Sprites only some of the gradients are surviving the embeding process. From what I've found simple (2 step) horizontal gradients seem to stand the best chance of being preserved, but sometimes other kinds of gradients are as well. In one case simply rotating an object 90 degrees causes the gradient to vanish when displayed in flash. Does anyone know a rough set of rules to use when creating svg gradient fills so they are preserved when rendered in flash? BTW: I used Inkscape to create the images in question.
Update: Bizarrely the solution to this seems to be setting the opacity of any object in the svg file whose gradient isn't displayed properly to a value below 1. Don't ask me why this works but it does. It does however have the unwanted side effect of the objects edges not being rendered as smoothly.
I have the following XMLList and am trying to return the XMLList with the node having the label Mail Box or Outbox, depending on string variable called folder. folder can either be equal to "Mail Box" or "Outbox".
I'm trying to loop through an XMLList and rather than giving me each item in the list as XML, it's just coming back with the positions as strings e.g.
[Code]...
It just alerts "0" or "1". If I inspect the 'item' variable, I see the same thing. But if I inspect 'myList' it looks like the XML. I've also tried myList.children() and strongly typing 'items' to 'XML' but nothing I do has worked.
If I have an XMLList object in Flex, what is the proper way to check to see if the list is empty? Should I just compare the result of myList.length() > 0, myList.toString() != "" or try another method altogether?
Is there anyway of type casting an ArrayCollection to xmllistcollection or to xmllist or can we covert ArrayCollection to xmllistcollection or to xmllist?
However this displays the datagrid with two rows, the first row has 1 in the Series column and then the two files crammed into the second cell in the same row. The second row is the same but has the number 2 in the Series column and the two series #2 files crammed into the cell next to it.If i do not use the nested data class i can pull the files using Series.file instead and all 4 of the files list correctly, however i do not get the Series number for each...
I have seen numerous examples on how to remove duplicates in ArrayCollection but I can't seem to transpose this to XMLList. In most ArrayCollection examples, the example compares the key of the array with hasOwnProperty method and return a bool. That's fine, but what would I compare to when using an XMLList? Let's say I have:
Given this XML code:[code]I can count the total number of game elements in the XML.game with:[code]Is there please some way to print the number of all game elements having the exact number of 3 user children? And also count all such elements with less than 3 user children?[code]The backgound is, that I have a Flex game, where up to 3 players can sit at a playing table and I'm trying to display the number of All, Vacant and Full playing tables there (the top left row with RadioButtons, sorry for the non-English language):I'm reading the XMLList doc, but don't see how to do it with one-liners, I only can see how to do it with loops...
I've got a movieclip in my library called primaryCommMC.I'm loading these 5 times onto the stage and naming them commMC0-4 using the following:[code]Right now they're all obviously loading on top of each other. I want to stack these movieclips on top of each other so the first movieclip will be at y=0 and the following at y=(the height of the proceeding MC + 5 (a little gap)).
How can I obtain the position of a instance whose name is stored in an variable? If there is a instance whose name I don't know, but the instance's name is store in an variable x. How can I obtain its position?
