ActionScript 2.0 :: Tree CellRenderer Not Working?
Nov 5, 2009
The following test code adds an asterisk in front of the node labels of a Tree component.It works in a trivial Flash document but displays blank labels in a much more complex one. In both cases the library contains a Movie Clip with name, linkage identifier and AS 2.0 class all set to "MyTreeCell".
Scene:Layer:Frame:
createClassObject(mx.controls.Tree, "myTree", 1);
myTree.dataProvider = '<node label="Mail"><node label="In"/><node label="Out"/></node>';
myTree.cellRenderer = "MyTreeCell";

I have a intro to a picture of a tree which has buttons on it. The intro is an embedded flv video (not using the FLV component). The video starts on frame one and runs to frame 2. The tree is on frame 3.When I click a button on the tree, it runs the respective frames then returns to the tree. When the tree appears, the sound of the video is playing in the background.How can I make this stop?
Code:
stop();
MovieClip(lion_mov).stop();
//video Mouse Click[code].....
Frame 3 just includes all the mouse clicks for the tree.

I have a Main.swf application that loads another application called GridServices.swf. The GridServices.swf contains a DataGrid that has a custom CellRenderer class associated with ithen I run GridServices.swf by itself, it runs just fine and uses the wordWrapCellRenderer class that I made.hen I load the GridServices.swf file into Main.swf, I'm getting this error all of the time:

I'm used to item renderers in Flex but inexperienced with Flash AS3 components.I want to create a List that renderers items like this:
1) a slider
2) a couple of text fields that my designer can place and style as he likes
It's a survey form. I expect to grab the _listData.owner and dispatch the user inputs and bubble them up to the form.
1) drag a list onto the stage
2) create a symbol in the library with the base class of com.blah.skins.renderers.SurveyItemRenderer
3) Export this class as SurveyItemRenderer
4) set the list's cellRenderer style to SurveyItem renderer
5) give the list data to show
I tried using CellRenderer, but the class seems to reject being associated with a symbol (and I could not find any examples of CellRenderer being used that way), so SurveyItemRenderer implements ICellRenderer.When I run it, other library symbols and graphics shows up in the renderer--WITH THE EXCEPTION of the slider. Other Flash components that I put on the stage do not show up either, until you roll over (Button), or if they have text in the them (Label). Slider never shows up.
Components will show up on the stage, just not in the SurveyItemRenderer. WHY NOT? I feel like I'm missing something basic. Here is the class, minimal because I'm still testing:
Code:
public class SurveyItemRenderer extends MovieClip implements ICellRenderer
{
protected var _listData:ListData;
protected var _data:Object;
protected var _selected:Boolean;

which I can't seem to solve. I'm using a cellRenderer to display icons in a dataGrid. All works fine until I type in the command myDg.hScrollPolicy = "auto". Once I issue that command, the icons stop displaying. If I remove that line, all works well once more.

I need to put a combobox in a column of a datagrid. The user just need to select a value from the existing combox items.I know I need to use a custom cellrenderer. Please see my current attempt below.This attempt successfully inserts a combobox into the datagrid, BUT without any data in the combobox. In fact, when I click on the combobox in the datagrid, it is the same as a normal combobox on the stage without a dataProvider. In other words, it doesn't even open.Thus, I need to know how to modify my cellrenderer to correctly add the data to the combo and accept changes made by the user when selecting a value from the combobox.[code]

The following code is the cell renderer for for a ComboBox in a DataGridColumn. It works fine when setting the comboBox's data in the constructor. There's a problem using the red code below. If the DataGrid row is not already selected the dropdown list appears but is empty.Any ideas? If the row is not already selected, the selectedItem is being set causing a STATE invalidation after the list a created. I'm not sure how to prevent this.

I have a combobox that I need to style with colors from xml. I call this XML file in the same class that has my combobox instance and break out the color I need to a var.
I then use MyCellRenderer (a class that extends CellRenderer) to style the drop down list items like so:
Code:
myComboBox.dropdown.setStyle('cellRenderer', MyCellRenderer );
This all works perfectly with a hardcoded color already inside the MyCellRenderer class.
My problem is when I instantiate MyCellRenderer and try to pass the color through I get the following error when I click the combobox open:
Code:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::DisplayObjectContainer/removeChild()
at fl.controls::List/drawList()
at fl.controls::List/draw()
at fl.core::UIComponent/callLaterDispatcher()
Is it possible to instantiate a class that extends CellRenderer? If not why not?
how can I pass a variable to my custom CellRenderer class?

I have a datagrid whose data keeps updating quite frequently.On every update, I need to change the cell color of only those cells whose data has changed.That too, if the updated value is less than the older value then the cell color should change to RED else, GREEN.
I have tried using labelFunction, cellrenderer, etc. But to no avail.By no means, I am able to access the present data in the cells to compare it with the new data.I have added the sample classes in the attachment. To get them to work, just create an fla with a DataGrid & a Button components in its library & mention 'del' as its document class.Just run the fla & click on the two buttons on stage to see the values in the price column changing.

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

I recently used fl.controls.List to implement a list with custom CellRenderer.I did it by implementing ICellRenderer:[code]Inside MyRenderer I added a fl.controls.Button, then set its label. However, when the List is rendered (by dynamically adding item into its dataProvider), the button body is not rendered, only the label is rendered. When I move my mouse over it, the button is then properly rendered.I found this strange, then tried use myButton.drawNow() in constructor. The problem seem to be solved. Now the button is rendered, but the label is not at the very center of the button (it's a bit towards right). Then, when I move my mouse over it again, the label move to the center, and everything's ok.This may be a minor problem, but I just wonder why this is happening. Why must drawNow() to be called? Why the label is not properly placed even when drawNow() is called?

I am developing an application and making use of a list component. I have set the List to use a custom cellrenderer.I need the list to have rounded corners but the problem is that where my custom cell corners are transparent I can see a default white cell underneath instead of the background.I found this discussion seemed to be relevant http:[url]......But when I add this function to my cellrenderer class I get compiler error
override public function set data(data:Object):void{
super.data = data;
Set the default skin to be invisible. This is a bit easier than creating a new skin, if your goal is to hide the white background.
this.skin.visible = false;
}
1119: Access of possibly undefined property skin through a reference with static type MarksCellRenderer.
how to hide the defualt white cell background?

The code below sets up a List object in the main controller class that uses a custom cell renderer (CustomListCell class). the CustomListCell class creates a Button object for the cell that will be used to delete itself from the List's DataProvider. How can I properly access the parent List object from its custom cell renderer?
//Controller Class
private function createList():void {
provider = new DataProvider(data);
list = new List();
list.width = 200;
list.height = 400;

I am attempting to combine two AS files that are acting as cellRenderers individually but not simultaneously for cells in a datagrid in a Flash document I have created. The first styles the cells to have alternating row colors and the second allows for non-text content to be rendered. The issue is whenever I attempt to combine them the document reports errors with "super" and "override" among others.

I want to program a program that draws a Pythagoras tree. The only programming language I know is C but I tried it in that language and it was horrible. Someone recommended Flash (AS3) to me so I am trying it in that now, but I only started yesterday so that's why I am posting this in the newbies forum. If this belongs in the math forum, then please move it there.
Anyway, I got to the point where I can draw the leftturning branch of the Pythagoras tree, but I don't know how to draw the other branches. The number of "houseshapes" a square with a rectangular triangle on top increases with every step according to the formula 1 x 2^(n-1) (First step is n=1). I created a function that draw this houseshape, called drawHouse() and it takes as its arguments the co-ordinate of the lower left corner of the square part of the house, the length of the side of the square part of the house and the current rotation angle. Rotation angles are always multiples of 45 for now, but I might try to expand it to other values later, but for now I hardcoded a lot of stuff that assumes the 'roof' of the house is a rectangular triangle.
how do I store the 2 new x and y co-ordinates that I can calculate after drawing the houseshape, for drawing the next houseshape, and how do I store the angles? Do I need 3 separate arrays for x, y and angle? And how do I then call the houseshape function for every x and y co-ordinate and angle in these arrays? Code is attached.

I noticed that mx:Tree inherits from List anad that treeListData supports a "columnIndex" property, but in my tests columnIndex is always 0. Does that mean I can actually add a column to a Tree? How?
What I'd like to do is have the end-nodes of the tree (the leafs) have "value" property that can be edited, and have that value appear in a fixed column. -- so column 1 is naviagation. column 2 is editing, basically.
I can always do it with an itemRenderer but I figured I'd ask you folks if there was a pre-existing solution already. Is there?
Also, is there a way to turn on horizontal scrolling? My data runs kinda deep in spots.

Given there is no tree component in Flash CS3, I used the following tutorial [URL] and managed to populate the tree from an xml file. However I am now finding it difficult to perform certain actions such as:
- adding/deleting items from the tree
- save tree back to xml format
- copy child nodes from one tree to another

I have created a tree diagram using the 'Tree Component' in flash, and have linked it to my XML file:
<?xml version="1.0" encoding="iso-8859-1"?>
<node label = "Sports Club">
<node label = "Ball Games">
<node label = "Tennis" />
<node label = "Soccer"/>
<node label = "Bassball"/>
[Code] .....
If you haven't noticed yet, the tree diagram is nothing complicated, it branches out as 'ball games' and 'athletic games' with sub categories such as tennis, soccer etc. (or 100 Meter & Hurdles for Athletic sports.) Now I've managed to go this far, BUT, what i'm trying to do is that when the user chooses the subcategory e.g. 'Tennis' from the tree diagram, I need to get text into a blank text-box.
