Flex :: Dealing With Automatic Adding Scrollbars?
Sep 3, 2010
I'm creating a container and it's content at runtime. Here's a rough structure:
--VBox
----Form
-------FormItem
[Code]...
I've tried also validateNowand other similar methods. What I have here:
1. The HScrollBar is being added.
2. We increase a bit the width of container, so it disappears.
3. When it disappears, the validating throws the null-pointer exception when it tries to measure the non-existing scrollbar. I've also tried to add validateProperties before validation, but it didn't worked either.

Having some problems adding the default spark.components.VScrollBar scrollbar. All I'm doing is creating a new VScrollBar, setting it's coordinates, a width and height and doing an addChild but it's not showing up. I'm adding other components too that do show up in the same code so that shouldn't not be the problem.What might I be missing?
var a:VScrollBar = new VScrollBar();
a.x = 100;
a.y = 100;[code].....

How do you change the html scrollbar (the one that you see in the far right of your browser) with your own images? I know it's possible because i've seen it before.
P.S.: I am aware of and I know how to change the color of the scrollbar. That is not what's expected. Also i think it's made possible by Javascript.

I'm trying to get data from a namespaced xml file in a flex app. There is a root namespace (xmlns="blah") and another namespace (xmlns:i="blah"), and I'm able to access most tags using the following:
var ns:Namespace = doc.namespace();
var result:XMLList = doc.ns::element;
However, there are several tags that are subject to change in the application, and i'd like to not hardcode them, possibly using the elements method:
var result:XMLList = doc.elements(configuredField);
Is there a way to get elements with namespaces using the elements method, or a similar way to get XML elements in flex using a parameter?

I have several nested VBoxes in flex, and I'm aiming for one of them to get scrollbars if the total content is larger than the window height. However, when I grow the container, it doesn't get scrollbars at all (vertical scroll policy is AUTO), and the outer container stretches past the bottom of the screen, causing the entire app to get scrollbars. So it looks something like this:

I'm using an iFrame in a Flex 3 project. The problem is that if the user opens my site in a small browser window, they don't get scrollbars. How can I solve this problem? Is there a way to force the browser to put up scrollbars?
If I set the main app to horizontalScrollPolicy="on" verticalScrollPolicy="on" or to "auto", then as you scroll down, the iFrame is stuck to the top of the browser window and obscures the content.
In the main app:

It's going to be used to view complicated scenes in 3D, but to make it work on laptops it's instead showing pre-rendered 360 degree renders of the objects.When you load an object, it first buffers 360 frames into memory, so that you can rotate around this object smoothly. When you release the mouse button, it loads in the high-res image of that frame.
Then, you should be able to zoom in and move around to inspect the model closer.Problem here is when I have the scrollbars enabled it wont work properly.Firstly, I had a problem where the vertical scrollbar moved out of the picture when I was scrolling the horizontal scrollbar.
Then after some more testing, they now stay where they should, but when I zoom in (will post code below) the horizontal scrollbar is not able to go far enough to the left to show the whole image.What happens is, when I zoom in, the scrollbar remains at it's left position, but I zoom in on the center of the image (zooming, by scaling the container. The image fill the container).
My problem is probably just a result of me overlooking some basic understanding. And sorry if the code is a bit messy, I've only done a little bit of clean up. The code I post below is without any scrollbars visible.
You can see that I've tried using scrollbar components too, and it works somehow. But I'm not able to scale the scrollbar depending on the content, so if I zoom in or out, the handle you drag on the scrollbar will be the same...
Image of app running if needed:
Code:
<mx:Panel x="0" y="0" width="100%" height="100%" titleIcon="@Embed('assets/img/cog_01.png')" title="vCog Subsea - Draugen Project">

I can take snapshot of a component. But the problem is the component is lil bigger with scroll bars. The saved image has scrollbars (only the visible area is getting saved). What i need is I want the entire component to be saved as an image.
This exact functionality is available while we print the component using FlexPrintJob, where by setting the FlexPrintJobScaleType.NONE.

I am using spark DropDownLists and I don't want to see any horizontal scrollbars in the dropdown. I'm OK with the dropdown being wider than the anchor, so I have a custom skin that sets popUpWidthMatchesAnchorWidth to false. But I don't want the dropdown to ever be smaller than the anchor. I came up with a solution that sometimes works, but there is something wrong with it. My DropDownList skin is as follows:
<?xml version="1.0" encoding="utf-8"?>
<s:SparkSkin xmlns:fx="[URL]" xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:fb="[URL]" alpha.disabled=".5" minHeight="25">
<fx:Metadata>
[Code] .....
This works as expected when the contents of the dropdown are either wider than the anchor or smaller than about 100px, but if I explicitly set the width in the instance of the DropDownList to be something like 200px and the contents of the dropdown are around 150px wide, the dropdown is smaller than the anchor. Basically, it looks like openButton.getExplicitOrMeasuredWidth() returns about 100, regardless of what I set the DropDownList's width to be. How can I change this so that I can have multiple DropDownLists with different widths, but always making sure that the dropdown's width is either greater than or equal to the anchor's width?

I have the following spark Scroller
<s:VGroup width="100%" height="100%" gap="0">
<s:Scroller width="100%" height="100%">
<s:DataGroup width="100%" height="100%"
[Code]....
which is set to 100% width. The DataGroup is also set to 100% width. What I want to achieve is for the scroller's vertical scrollbar to OVERLAP the DataGrid. In other words I want the DataGroup to maintain the width of the outer VGroup even when the vertical scrollbar is displayed. I don't need the vertical scrollbar to move my content to the left, i want it to be displayed in top of that.

I posted the same question but I think it was not so clear. Now I am rephrasing my question with real problem.I have a flex application. It is basically a web application. On it I have a player that play avi files and some buttons and tabs along side.The application also have recording button that records that direct stream from an IP cam and store that stream on the media (USB). How can I automate function testing of such application. Like I have confusion that when I press the recording button but can I be sure that recording starts? I have tried RIATest and flexUnit 4.

I have a DropDownList inside the itemEditor of my DataGrid. There are enough items in the DropDownList to justify scrollbars. You can see the scrollbars, and the mousewheel works fine. If you move the mouse over the scrollbars, they'll change appearance fine (mouseover is working). If you click on them, the DropDownList closes as if you'd clicked elsewhere in the data grid.
I've been experimenting with custom skins hoping to find a way to trap the mouse event, but have been unsuccessful.
FWIW, this is Flex4, as an AIR app.

I am trying to have a tool-tip in Flex 3, where in when my mouse is over the some value, it should show a tool-tip just like you get it for any classes in Eclipse IDE. Suppose, your mouse is over word "String" in java, you get a tool-tip stating the description of java.lang.String and its syntax. It also allows to copy the contents. Is it possible to create such a tool-tip in Flex 3 ? I want this kind of tool-tip to appear, and when pressed F2, it should have horizontal and vertical scroll bars and we should be able to copy the contents from tool-tip.

I have two panels and a button nested within an hbox. I want the panels to appear side-by-side and the button to appear under both panels equi-distant from the sides of the hbox (i.e. in the center).Getting the panels side-by-side was easy, but how do I get the button below both panels and in the center. Currently, the button show up to the right of the second panel.

I have an editable datagrid. If sorting is applied by clicking any header of datagrid, it works fine. But after that, if data values are changed in any row of datagrid, sorting is applied automatically. How to prevent from this behaviour? i.e. sorting should only be applied if user clicks on any header of datagrid and sorting should not be applied when user modifies data in grid.

I'm trying out the Flex Builder 3 Plugin for Eclipse, and it doesn't seem to have quick fix or automatic imports. I use those two features a lot with Java and FDT. I've been googling, but all I've found is some plugin that someone wrote for Flex Builder 2, and no other mentions. Is Flex Builder supposed to have these features?

I'm making a small memory game that is XML driven (users can upload images into the game). I've come to the point where I need to check if the user has filled out certain nodes or not, and if so; check that the input is valid - int when int is expected and whatnot.
What are the ways to check this, and which is best? So far I've only tried checking if a node is == "" or not, but I imagine there must be better ways. I will include lots of switches for the user which should all be optional. This calls for a neat way to validate it.

I have an app that has a fullscreen button that goes into fullscreen NO_SCALE. Keeps everything looking sharp. However, all of my movieclip positions aren't correct. To fix this, I need to use:
Code:
stage.addEventListener(Event.RESIZE, stageResize);
Then, in my stageResize function, I duplicate all my movieclips' x and y and (if necessary) widths. This seems wrong and cumbersome.
Here's an example of what I'm talking about. Full Screen - Doesn't Work Clicking on fullscreen brings you to fullscreen but the mc positions stay put. Here's the code for this one:
Code:
var btn_fullScreen:btnFullScreen = new btnFullScreen();
var btn_normalScreen:btnNormalScreen = new btnNormalScreen();
var bar_bg:barbg = new barbg();

Everything dealing with sharedObjects in the first frame is this:
[AS]
var PlannerData:SharedObject = SharedObject.getLocal("PlannerData");
SubjectChoices = PlannerData.data.subjectChoices;
if (SubjectChoices == undefined) {[code]....
Going to the second frame from the first frame, the data is perfect. Going back to the first frame from the second, I'll trace the data many times throughout the code without an onEnterFrame, and it'll tell me that the Array is good...But when I trace the onEnterFrame, it shows the Array is [undefined, undefined, ...] like..undefined 17 times.
