I am trying to implement some MVC-style UI components in Flex 4. I want to further separate the visual setup (and later runtime modification) of each element. Primarily, I want to keep the overall layout of the data like such in the MXML file that will USE the skin[code]...
View 1 RepliesI've been having trouble creating a mechanism to allow the user to select a span of time from a timeline. Basically i want them to be able to click and drag horizontally, and retrieve the start and end positions of that event.
I especially need to include the case where the event goes off the edge of the screen (even if the end position is snapped to the edge of the screen that's fine).
While doing all of this, I want to be able to draw a box that goes from the start of the event to the current position of the mouse, so that it's obvious which area if being selected.
just like a title. I discovered that "buttonmode = true" is not enough to make a button that would act the same as "button symbol" in timeline, what properties should I set furthermore?
Background: I made my own scroll bar in AS3. That scroll bar uses a knob, that is a movie clip, I found that if I will enter inside that mc and make another symbol - "button" inside (from the same graphic) it will act very nice, BUT if I set that mc to "buttonmode" in AS, it works different. Yeah it has hand, but when I'm dragging it too fast, I'm often "losing" it. It looks like the graphic is not keeping pace, BUT (as I wrote before) if I will create a button inside that mc - it's perfectly glued to my cursor. So what should I code to get the same kind of button that I would get by entering mc and creating a button inside?
do anyone know how to load in an UIloader purely with action script withoud dragging it onto the stage?I have try the following code but it just can not work.
View 3 RepliesI am familiar with the method of embedding a SWF file in Actionscript and then creating a variable and assigning a corresponding UI element from the SWF.Is it possible to create and place UI elements like TextFields and SimpleButtons purely with Actionscript without first creating them in a SWF and embedding it?

Is there a way to declare a skin inline in a Flex 4 MXML Component? If not inline in the component then in the declarations or library tag?
View 1 RepliesI am attempting to implement a layout in Adobe Flex 4.5 / MXML where I have multiple controls in an HBox that - in total - consume all available horizontal screen estate. Some use a relative with (percentage), some an absolute width (pixels) and one is supposed to consume whatever space is still left, such as:
+----------------------+-----------------------+------+
| 35% | fill parent | 10px |
+----------------------+-----------------------+------+
How would I achieve this in Flex (is there something comparable to Android's
layout_width="fillparent")?
Due to the fact that there are elements that have an absolute width I cannot easily calculate the width of the filler as a percentage a priori (as it varies with the screen width). Setting the filler's width to 100% also does not work as this will shrink the 35% area below 35%. Applying the updateDisplayList suggestion from www.Flextras.com's answer below yields the error "Call to a possibly undefined method updateDisplayList" at the line marked in the source excerpt below:

Problem: Users of our web app are complaining how hard it is to get past Flash Player's Security Panel when they want to make video calls. (Personally, I don't see why it's hard.) We tried several things to guide them through the process, including callouts pointing to the Security Panel area with specific instructions and even an auto-play video. But still some don't get it. I think the biggest confusion is the "Close" button. Users think that it will close the app or the entire window.
Solution #1: It's possible that part of the problem is the small size and styling of the Security Panel.Is it possible to apply a style or skin to the Security Panel, so that it's larger and looks more consistent to our web app?
Solution #2: Perhaps there's also a non-technical solution. Has anyone seen a good implementation of a web app that make it easy for non-technical users to make video calls?
I want to use actionscript 3 to create mxml(flex 4) controls dynamically and automatically taking care of layout. For example, if I want to put 6 buttons and a s:label in a layout container by just specifying the positioning of the container and not the locations of individual controls.
View 1 RepliesSkinParts are a great way to add event handlers and logic to an object that is instantiated in the skin, away from any business code. Often, though, I find myself wanting to do the opposite, and define parts that will be used in reusable, skinnable containers in the parent mxml files which will be inserted into the skinned containers.
What's the best practice for when you want to be able to define a control and a skin which can be reused with different controls inserted from outside the skin? Edit: A better way to put this might be that I want to use something that works a little bit like a SkinnableContainer, but that isn't limited to one area where content can be placed.
I extend Button to create ImageButton, and I extend ButtonSkin to create ImageButtonSkin. But, when I define hostComponent like this:

View 2 RepliesI've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
This is a project I'm working on for a simple demo tutorial application in Flex. I am using mxml pages.

How can I dynamically pull the value from the object in the list to load the child mxml file into the container that I have further down in the application?

I'm using the default CS4 FLVPlayback skin, mainly the SkinOverPlayMute.swf. I know there's a skinAutoHide option, but because I don't want it to auto play, I want people to see a play button when they first encounter the video (so they don't think it's just an image). But the skin needs to hide when the video is actually playing (so the video doesn't get blocked by the controls).
In other works - when video isn't playing: skin showing; when video is playing: skin hide.
