Actionscript 3 :: Flex : Make A Generic List Control That Has X Buttons In It

Dec 3, 2010

I am trying to make a generic list control that has x buttons in it so that users can remove items from the list by clicking the x button. However, this list control needs to support item renderers while still standardizing the layout of items placed next to x buttons.

So I figure the best approach would be to extend the list control and use a renderer that draws the x button and combines that with what ever renderer the user supplies. Unfortunately I cannot figure out how to do that.

I tried overriding newInstance method from the IFactory interface and used that to create an HBox that contains my button and inserts the newInstance result from a user supplied renderer, however it wasn't complete. It displayed as I expected, but the mouse over effect only worked on the user supplied renderer portion and not the entire HBox that my custom renderer made.

Actionscript 3 :: Make An Item In A Flex List Control Not Selectable?

Jan 12, 2010

Is it possible to make an item in a List control not selectable? If so, how would this be accomplished?

I've tried one thing so far. What I did was use a custom item renderer that checks for a value in the data property upon a FlexEvent.DATA_CHANGE event. If that value is not set, I tried setting the item renderer's selectable property to false. This, unfortunately, does not seem to work.

Flex :: Scrolling Of List Control Is Misbehaving?

Dec 22, 2009

I am having this very weird behavior with a mx:List control not scrolling properly.Here is a snippet:

<mx:List itemRenderer="customerRender" x="19" y="257" height="68" width="290" id="orderStatusHistoryList" color="#CCCCCC" rowHeight="35" ></mx:List>

The custom render creates a vBox that is 35 pixels high with some labels in it.Now, my dataProvider, set in the script block,is returning 3 items for the list (say item1, item2 and item3). Because of the height of the list control, only 2 are shown initially.Now for the weird part, when I scroll down the list to see the next item it is all messed up.

Initial display:
Item 1
Item 2

Display after clicking the scroll down button:

Item 2 (expected)
Item 1 (What the ?, this should be item 3)

Display after click the scroll down button one more time:

Item 1 (all wrong)

Now, if I increase the height of the list control,so it has enough room to display all three items, it displays fine.Also,I put a trace statement is the item render and flex is rendering all three items with the correct data.

Flex :: Add Separator Between Items In A Spark List Control?

May 21, 2010

I have a s:List where I've defined my own itemRenderer, and would like to insert a horizontal line separating items, similar to the way the mx:LinkBar works. I don't want to have a line at the top or bottom of the list, so I can't just include an upper or lower border in the itemRenderer. I was hoping the itemRenderer could be made aware of its index in the list, but I don't see how.

Flex :: How To Set Variable Size For List Control Item

Jun 17, 2010

The following code display a list of comments using List control. The item height set to a fixed value (150), so it seems working: if the content is too long, the scrollbar shows. However, what I really want is not to set the height but let it to change according to the content size. Is there any way to accomplish this?

<mx:List id="commentList" width="100%" dataProvider="{commentSet.commentArrayColl}" rowCount="{commentSet.commentArrayColl.length}" >
<mx:itemRenderer> <mx:Component>
<mx:VBox width="100%" height="150" >
<mx:Text text="{data.commentContent}" />
<mx:Text text="{data.username} ({data.modified})"/>
</mx:VBox> </mx:Component>
</mx:itemRenderer> </mx:List>

To be more clear, I don't want to set the itemRenderer's VBox height to "150" or any other fixed value - but it'll only show one line of the text if I don't do it. So I'm looking for a way out of this. (If the VBox is not inside the itemRenderer, it'll auto adjust height as Text field string length grows - that's what I want.)

Unable To Make The Imported Buttons Control The Timeline Of The Parent?

Jan 18, 2009

I have an swf file, MyRoundButtons, which is a set of radio buttons I built (not components). It works fine, but if I import it into a parent it won't work anymore. I have to write a script to load it into a movieclip, (which I hate, because I'll have a several different swfs to assemble on my final stage. I really want to see them all on the stage together, not just at runtime.)

Even when I load it into a clip and the buttons work, however, it doesn't seem to have a separate timeline when double-clicked ,and:I can't make the imported buttons control the timeline of the parent.I defined a test function:

Code: Select allfunction goToNirvana() {gotoAndPlay("nirvana")};

Frame "nirvana," in th parent, has a Trace instruction in it.
goToNirvana works on its own in the parent. [code].....

Whether I define that function in the child, the parent, or both, the instruction won't work. Now, I'd prefer not to do the loadMovie thing at all if I can avoid it, I'd rather have fully rendered button clips onstage at authoring for me to arrange and move about, with fully independent timelines right there. But you see what I'm trying to do. I just can't get it done.

Edit for clarification: When you set "dragEnabled=true" on the TileList, it takes care of the drag source stuff, but it uses "items" as the format for the DragEvent. I'm looking for a way to have the TileList use the correct format.

Flex :: Designing A Generic Toolmanager?

Aug 14, 2011

I want to handle multiple operations on a UI Component (button ,textfield, swfs,custom objects etc) in like scaling,skewing ,color,rotations etc etc and save them too. Earlier the actions were done

using a single tool and single mxml file but now the tool is separated into different tools. Was wondering how i can design / use something like Toolmanager class to handle actions etc?

Also the tricky part is that some objects can have more operations defined for them Like 'object1' has 3 operations that can be performed on it and 'object2' has 5 operations defined on it.

We are using MVC design pattern but no frameworks as such. What are the different design patterns that can be used to do this? Edit: To be more precise i want implement this in AS3 OO way.The application is similar to drawing application which supports addition of various images,text,audio,swfs etc. One added user can perform various operations of the objects..like adding color,scaling skewing,rotation etc etc and custom effects and after that export the drawing as PNG.Likewise some effects that are applicable to text are not applicable to images and vice versa. and some effects can be common.
