Flex :: Override Data Tip Circle?

Jan 31, 2012

In flex charting you can customize the box which displays datatip information, but is there any easy way of changing the little circle which is displayed next to the datatip box?

http:[url].....

I've found the method positionDataTips() in ChartBase which appears to do the drawing of the circle. I was going to subclass LineChart and override the method with my modified version of it. However, this method needs access to a lot of private instance variables which are only accessible to ChartBase.

Flex :: Cant Edit Item In Datagrid With Override Set Data Method?

Mar 12, 2010

I've a custom itemRenderer for my datagrid. To set the actual data I use the following method:

Actionscript 3 :: Flex - Why Override Custom Event And When To Override It

Flex :: Override Child Node Controls In A Flex Tree Control?

Aug 20, 2010

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:

private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....

I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?

override protected function createChildren( ): void
{
super.createChildren( );[code]............

Here is my tree tag:

<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />

ActionScript 3.0 :: Erasing A Circle From Bitmap Data?

Sep 29, 2009

I'm trying to create sort of an eraser to remove sections of a bitmap on stage.

I have achieved this by creating a MovieClip in flash that is a circle and exporting it as a Class called Hole.

Now I use this MovieClip to erase a circle section of the image using the following.

var mat = new Matrix();
var ct = new ColorTransform();
var hole = new Hole();
mat.translate(x,y);
image.draw(hole, mat, ct, "erase");

Now what im trying to do is scale the size of the circle depending on a certain variable but no matter what I try the scale doesn't seem to change and. The size seems to stay the same as I drew it in Flash. I tried adding the following line

hole.width = hole.height = size;

I even created a class file called Hole and the size as a parameter

var hole = new Hole(200);

This didn't work either it still appeared to have the same size. I have even tried altering the scaleX and Y values with no success.

Css :: Override Value To Be Empty In Flex?

I have a Flex 3.2 application for which I am developing a custom style. Basically the first stylesheet gets applied first, and then my custom stylesheet. I am wondering how I can completely empty a value set in the first stylesheet with a value set in the second. The value has to be blank because if the horizontal-center value is set then any other positioning values are ignored.

Example

Actionscript 3 :: Clever Data Structure To Represent Layered Circle?

Feb 9, 2010

I'm making a game and I need to represent a "layered" circle in some clever datastructure.A circle can have any number of layers. Each layer has a number of "slices", they can be of different lengths and pieces can be missing. The innermost layer is always a full circle.Each segment has a color, multiple segments with the same color can be next to each other. Realistically a circle wont have more than about 40 layers or about 1500 individual slices.I will need to be able to easily find adjacent pieces to a specific piece, see if a piece is "hanging in free air" (imagine gravity towards the center), and to remove pieces leaving a hole in their place.

Flex :: Override Function Set Label Of A Button?

Sep 24, 2009

I trying here to avoid having to bind resources to all my components labels ( ie a button) and find a way to have this automated.

Problem: It corrupts the layout in design mode to bind directly in the mxml label="{resourceManager.getString('myResources', 'submit')}" and makes the design view useless. but when declaring bindings elsewhere, in actionScript or via a bind tag, it is counter productive and prone to many errors and miss.

Proposition: I would like to create my own button that automatically invoke resources to localize a button label. So the author puts "Submit" in the mxml description of my button, and when running it would take the value of the label ie "submit" and use resourceManager.getString('myResources', 'submit').

but I can't find the way to override the set label function, Is it possible if yes how? else how can I go about it?

Maybe I am missing an essential process here that would make the use of resources more elegant, as well as how to override such thing as a button's label.

Flex :: Override Mxml Request In An HTTPService?

Mar 10, 2010

I have an HTTPRequest in mxml that has an mx:request defined inside it. I use the info in the mxml request 99% of the time (I thought it was 100% until I found this bug). So I need to send the HTTPRequest with one of the items in the request different. I tried using the send() method and sending my own object, much like you would if no request was defined in the mxml, but it doesn't seem to override it.

Any ideas how I can accomplish this without re-writing every call to send this httpRequest?

Flex :: Override Default Handling Of Editable Lists?

Aug 5, 2011

I'm trying to override the default handling of the 'up' and 'down' keys for an editable list, such that when they are pressed a list entry that is being edited behaves as if the escape key has been pressed, but the 'selected item bar' moves up or down.

Here is my (simplified) component:
<?xml version="1.0" encoding="utf-8"?>
<mx:List xmlns:mx="[URL]"
enabled="true" width="100%" height="100%"
creationComplete="initialise()"
editable="true"
[Code] .....

For some reason this doesn't work: if a row is being edited, the first 'up' (or down) keypress ends the edit and moves the bar. Further up or down keypresses have no effect, but if you click somewhere near the list it does start working. This makes me think it is a focus issue. Weirdly, if you hit escape the edit finishes and you can move up and down correctly. If the 'callLater' line is uncommented to try and make the list retain focus, the bar initially moves in the direction of the keypress but then moves back again and re-edits the original line!

ActionScript 2.0 :: Calculate The Direction And Speed A Circle Has After Colliding With A Static (non-moving) Circle?

Mar 8, 2005

I'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision

If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?
