Flex :: Ensure That The PopUp Always Displays Above The PopUpButton?
Apr 2, 2012
Few users of my Flex 4.6 web application are complaining, that the mx.controls.PopUpButton at the right bottom corner of it sometimes opens a List underneath it and is thus unusable (I can't reproduce that myself - probably an unlucky combination of their Flash player and/or font size setting?)
How could I ensure, that the popUp component (in my case it is a spark.components.List) always opens above the PopUpButton?
I suspect, that I should create a skin based on mx.skins.halo.PopUpButtonSkin and assign it to my PopUpButton? And I probably should use the PopUpPosition.ABOVE constant together with the PopUpAnchor?
I have prepared a screenshot and a simple Text.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
[Code]....
I still can't reproduce the bug myself, my users aren't very helpful (mostly older folks, playing my card game). I've searched in Adobe JIRA, but couldn't find such a bug.
I wonder, if there is a way to short-circuit that method to enforce opening the popUp above the PopUpButton.
Or if I should put the _list into some container...

If you create a popup via:[code]It will create a popup and bring it on top of any other visual piece. I have one problem though. This 'popup' needs to stay up even when the user interacts with the background.I would use modal, but I need the ability to interact with the back. Any way to tell the popup manager not to remove the popup when the user clicks off of it?

So I have a PopupButton and when I click on the button I want the Menu that pops up to have rounded corners. How would I go about doing this?UPDATE:I found an update similar to what I want to do, it can be found on the following page:The only difference is that I'm showing the Menu with a PopUpButton. So far this is what I have for my custom Menu:
package {
import flash.display.Sprite;

I am trying to programmatically skin a PopUpButton control in Flex Builder, but having no luck. As far as I know this requires writing a custom skin class or creating a modified version the control class itself (since the control is MX and not Spark). Again, just to clarify, I want to programmatically modify the appearance not simply set styling properties or display an image. I've been able to do this programmatically with other MX controls (e.g. tabs in a tab navigator), but not with the PopUpButton.I think part of the problem may be that the control is actually composed of two separate buttons, so you cannot draw just one rectangular area over the whole control.

I am using the Flex PopUpButton & data binding a Menu object to the popup. I successfully added an icon to a menu item; however, it does not look like Menu supports the disabledIcon property common in many other elements for use when enabled: false for that menu item.Is it possible to extend the Flex Menu class to use disabledIcon? Should I use a different type of data binding class?
// create the array collection of menu items
var menuItems:ArrayCollection = new ArrayCollection();
var addWidget:Object = new Object();

I have prepared a simple test case for a PopUpButton opening a TileList with black and red entries and it mostly works, but has 2 annoyances. I've searched a lot, tried several variants (added [Bindable] members in my renderer; added color member to the bids array; created my public override set data() method; ...) and has been getting some answers too, but they are way too general.
1) Scrolling "tl2" right-left doesn't work well: the entries are displayed in a mix of red and black. I know the TileList reuses itemRenderer, but how do I fix the problem?
2) In debug-mode I get numerous warnings: warning: unable to bind to property 'label' on class 'Object' (class is not an IEventDispatcher)

I have prepared a very simple test case to demo my problem.just place the 2 files below into a Flash Builder 4.6 project and they will run instantly.My problem is that the menu attached to my (slightly modified) custom PopUpButton never changes - even though the underlying Array data provider is changed when you click one of the 3 buttons on the right side of it:
AuxButtonTest.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application [code].....
I've commented my custom event out - it doesn't matter here.click at the buttons few times and then look at the menu - it always has 5 items and that is wrong.
AuxButtonText.mxml:
<?xml version="1.0" encoding="utf-8"?>

As we all know SuperTabNavigator is an open source component from the flexLib which gives an advantage over Flex Tab Navigator that we can close the tabs from the close button on each tab with the use of SuperTabNavigator. Additinaly there is a button to the right of the tab navigator which shows a list of all tabs which are open at one time and we can select any tab from that button which is a PopupButton.
Now what happens is when we close a tab, it disappears from the PopupButton drop down list as well. But in my case I want the drop down to remember the closed tabs even so that when I click on that closed tab it opens again in the tab navigator. I am relatively new with Flex and ActionScipt

In my Flex 4.6 web application I use mainly spark components, but there is also an mx-component - a PopUpButton extended by me (the source code is below).Users report problems with that button, but I can't reproduce any - since weeks.
I've tried replacing mx:Menu attached to it by a s:List but it hasn't changed anything. I suspect there is a "null pointer exception" or some other failure, that I don't hit when testing myself...
My question is: why does Flash Builder reports warning about my custom button as if its methods would be private or not present?
My main App.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"

I have a PopUpButton that only contains 2 actions. Both actions are complete opposites of each other and switches a boolean property on an object from true to false or false to true. To avoid redundancy, I've only displaying one action at a time. So, if the property is true, the action to change it to true is not shown.
If my PopUp menu has a single option, I would like to remove the menu from being shown and basically revert the PopUpButton to act and look like a regular button. So far, I haven't really found a good way to do that in ActionScript without adding, removing or modifying styles for the button.
Is there a nice way to simply tell the button to hide the PopUp toggle? PS: In my specific example, YES it might be easier if I just used a toggle button. However, I want to reuse this button when dealing with an Array of objects. If I have more than one, the property could be true and false at the same time. In that case, I want to show the menu so they can choose what option to set all the object's properties to.

I need to close the popup(adobe flex), non modal window if I click on the parent page of the popup. I have to do the out of focus check and then do some validation before close the popup. So what I was thinking that is there any inbuilt focus check event or do we need to create custom event for that?

I have a code like this:
<mx:Repeater id="allItemRepeator"
dataProvider="{_model.allItems}"
>
<components:ComponentSelector id="componentSelector"
[Code]....
When code changes for allItems the item disapears from screen as expected but still sits in memory! I know this by a function inside a compoenent that has "trace" so the trace output still displays even after the component disappears from screen. How do I ensure that the element is deleted when it's reference is deleted? Will using List-based component to display items instead of "Repeator" solve the problem (it requires significant refactoring of my code so I'm asking before trying it out)

I have a web application which contains a data grid. Double clicking on any row of that grid will open a popup (lets call it popup1). Now this popup1 again opens a new popup(lets call it popup2). When I close the popup2, I need pass an Object to popup1. Which is the easiest way to do that?
(PS: While opening popup2 from popup1, I am adding an event listener on Close event of popup2)

If I want to align things vertically in a container, I'll use verticalAlign="middle", but this doesn't exactly solve the problem of truly aligning text vertically. Text is always too high vertically, so in the past, I've just adjusted paddingTop and paddingBottom to compensate, but that doesn't work as the font for _sans differs from operating system to operating system.
Given the following layout code, you'll see the problem:
<?xml version="1.0"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
[Code]....
What happens is pretty clear. The horizontal line gets aligned to the exact middle of the box, but the text is offset by some arbitrary amount. I assume that this is because of the text baseline alignment or something. Is there a way to fix this regardless of the font size and face? I'd like to have the line essentially go right through the middle of the text, ignoring the extra space possibly needed for below the logical line of text (ie: ignore the bottom part of "g's" and "j's" when laying things out).

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 hit a brick wall here. I have a Flash file that displays fine in IE. It also displays fine when ran as a SWF. However, in FireFox, it does not display my scroller. I developed the Scroller component dynamically... everything is drawn from scratch, no library movieClips, etc. I'm starting to think that could be the cause? I've tried many different things:

I developed the Scroller component dynamically... everything is drawn from scratch, no library movieClips, etc. I'm starting to think that could be the cause? I've tried many different things: Changed the HTML code to bare bones embedding code.Recompiled in Flex.... same result!Tested on another computer... it worked fine! However, I tested on another computer with FireFox... same problem.
It's so weird.I seperated the Image Slide show component from the Scroller... the scroller had the same effect... didn't display in FF.Played around with WmodeChecked my code for addChild problems, visibilty, alpha properties... nothing out of the ordinary.Asked God.Drank some Gin.Took a break and came back to it.I've reseached Google and the most I could come up with is to compile using FP10. It is FP10. I'm using CS3 and FlashDevelop. When I right click on my Flash file, it does indeed display FP10. Same with Flex.

I'm trying to work out a specific problem I'm having with positioning in Flex using the PopUpManager. Basically I'm wanting to create a popup which will scroll with the parent container - this is necessary because the parent container is large and if the user's browser window isn't large enough (this will be the case the majority of the time) - they will have to use the scrollbar of the container to scroll down. The problem is that the popup is positioned relative to another component, and it needs to stay by that component.

I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that?Here's my parent:

However, my scripts only works well if it was tested in my local computer. In online environment, the images seems to load in a random sequence. so that the images loads according to the xml order?
