View 2 RepliesFlex :: Extending Mxml Component With From Another Mxml Component With Visual Child Supported?
May 18, 2011I'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?
Actionscript3 :: Flex - Widespread Are Naming Conventions?
Aug 30, 2010In 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.

ActionScript3 :: Flex : Programmatically Associate A RadioButton With A RadioButtonGroup?
Jul 27, 2009I 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:
control.groupName = groupNameForLevel(item);
control.group.addEventListener(Event.SELECT, updateSelection);
ActionScript3 :: Flex - Determine The Position Of An XML Instance In An XMLList?
Aug 11, 2009What 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.

Flex :: Load An External Mxml File Into A Parent Mxml File?
Mar 9, 2012This 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?

View 1 RepliesActionScript3 :: Flex - What Types Of SVG Gradient Fills Are Supported When Using The Embed Meta Tag
Jul 7, 2009I'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.

Flex :: Include An MXML File Inline Another MXML File?
Jul 25, 2011I would like to include an MXML file in my MXML file in the same way you can include an external file in AS3 using the include directive. Using the include directive brings the code from the external file into the original file at compile time placing it in the same scope. For example,

Jun 22, 2011I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.
