Flex :: Getting The Global Coordinates Of The Visible Area Of A Component?
Oct 19, 2010I am trying to determine the global coordinates of the visible rectangle that is currently rendered on the stage.
Specifically, if a canvas has an explicit height and width and is a child of a panel that has a scrollbar, the scrollbar can "hide" a part of the canvas. ContentToGlobal(x,y) provides the global position of the content at the time, but content coordinates can scroll off the boundaries of the parent panel and continue to give x,y coordinates that are not visible.
Is there a way to determine the viewable rectangle that is not hidden by anything?

Actionscript 3 :: Convert Global Coordinates To Local Coordinates Of A UIComplenent In Flex Project?
Dec 19, 2011I was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue
var lp:Point = new Point(e.localX,e.localY);
I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2
var lp2:Point = new Point(e.localX,e.localY);
now surprisingly it was giving correct values as expected and I went back and changed the code as
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
var lp2:Point = new Point(e.localX,e.localY);
var lp2:Point = uic.globalToLocal(gp);
now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.

Mar 4, 2011I googled for almost a day to find the answer to my question: [URL]. This almost works (and is a great solution), but the solution doesn't work when I do:
1). Copy and paste multiple-line texts.
2). Write long and scroll the texts.
I also found another working example at: [URL]. (The autocomplete prompt appears when you press ctrl+space right at the caret's position). But an email from its author says he uses monotype fonts to calculate individual character's location. Is there a way to get multi-line input from a textfield?
Flex :: Bind To Global Variables Inside Component?
Aug 19, 2009I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".

Feb 4, 2010I made a cube with as3. I wanted it to rotate in the Y Axis according to the horizontal mouse movement. It works nice when this is all I want. But if I try to also make it rotate on the X axis with the vertical mouse movement, things get screwy.
This happens because the transformations are added in the global coordinates, not the local ones. So, for Example, if I wanted the cube to rotate 30 degrees along its Y axis, I have to find a way to translate that into the global coordinates, and then apply that to the matrix3D of each face. I need a local to global translator.

Flex :: 4 - Null-component - Checking If The Cancel Button Component In The Child Component?
Jun 23, 2011I 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?
ActionScript 2.0 :: Converts 3d Coordinates To 2d Coordinates - Difference Between MoveTo And LineTo?
May 21, 2007I was reading the 'Isometric Transformations' tutorial by Danko Kozar and I have a few questions. I understand what all the code does, but not how it does it. First of all, how does the following code work:
transforms x,y,z coordinates into Flash x coordinate
xFla = function (x, y, z) {
// cartesian coordinates[code].....
I understand that it converts 3d coordinates to 2d coordinates, but I don't understand how. What numbers whould be punched into x, y, and z to acquire certain desired effects?Also, what's the difference between moveTo and lineTo:

style(1, "0xFF0000", 100);
plot(0, 0, 0);
draw(200, 0, 0);

View 1 RepliesActionscript 3 :: Flex - Using A Global Event Bus In Flex
Jan 18, 2011I am using modules in flex, to build different parts of my webapp. What I need now, is a way these modules can communicate with each other on events. What really is happening is ,that there is a central module, which then will take care of loading other modules and passing data to and fro. But, coding for each part to delegate events to each of these loaded modules from the central module and back would be a big nightmare.
What I really want to do is have a global event bus for it. Are there any specific libraries, already existing for such a process. Also, I would be using MVC, so it should also take care between events form the model to the view and vice-a-versa.
Flex :: Make A Custom Component Or Extend The List Component For A 2D Top Down View MAP ?
Nov 11, 2010I'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?

May 31, 2010I made a swf that interacts with other site on the internet (which has a crossdomainfile for me).in the main.mxml there is a definition of webservice (mx:WebService)(which is not in my domain). Therefore when loading the swf, there is a first call to crossdomainfile.xml.I put this swf on my server so that my clients can get it.
When i connect to my server to download the swf, i expect to be asked if i want to allow the swf connect to foreign webservice domain.Do i always need to define exception in Global Security Settings panel?I don't want my client do define special things..Is there a best practice for that? Why when i surfing the net other swf can do this? I read about the FlashPlayerTrust, can i define there a website i trust my swf will connect to?

Flex :: Obtain Item For Mouse X/y Coordinates?
Nov 24, 2009my mission is to select an item in a DataGrid instance with nothing but the coordinates on screen.
We are implementing right-click functionality in our Flash application, with the goal of being able to right-click a DG row, which would select that row plus show a popup window containing some context commands.
I have managed to get the right click event into my Flex app with the help of this site.
Further progress so far has been to obtain the DataGrid instance via
var objects : Array = this.getObjectsUnderPoint(new Point(this.mouseX, this.mouseY));
and then to investige each of the array's items, for one of those 'parent.parentList' refers to the DataGrid instance.
I couldn't find any point-to-item converter function or anything.
PS: Using the standard Flash ContextMenu is, unfortunately, not an option.

Php :: Get The Correct Coordinates Of Text From That Flex Editor?
Mar 1, 2012We have an image editor in Flex to add text and other changes. Once all the changes are complete, we need to save this to the server.We are using php to save the images by accepting coordinates from flex about what all edits are made for that image. Using this we are editing that image using imagick function in PHP. But the problem is output is different from what we see in flex. The issue is mainly with text alignment in flex editor and in the output we get after editing in php.Is there any other way to do this without making the user to wait for a long time to save the images? Is it possible to get the correct coordinates of text from that flex editor. Our issue is flex is passing the x,y of the container of that text editor. For this reason, test is misaligned in the output.
