Actionscript 3 :: Flex - Possible To Have Flex DataTips On Canvas Rather Than Chart Objects

Jan 17, 2010

Flex charts, like AreaChart, have wonderful built-in support for displaying data "tool tips" when a user hovers over a point supplied in the data of a graph. You can hover over any of the bar graph examples on this page for a demonstration. I have a graph situation where I optionally draw in some dots as reference points on CartesianDataCanvases supplied to my AreaChart through it's <mx:annotationElements> and <mx:backgroundElements> tags.

I would like to have the same hover data-tip functionality that the AreaChart has, but applied to these dots. I realize that I am just drawing on canvas, and that no actual dataProvider supports these dots, but if there was a way to supply the CartesianDataCanvas with an array of data values or something to that effect,

Aligning The Canvas To The Right In Flex?

Dec 8, 2010

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Canvas width="100%" height="100%">
<mx:Canvas backgroundColor="#A8A8A8" height="100%" right="0" top="0" width="100">
</mx:Canvas>

[Code]...

My code above works absolutely fine, until i resize my browser window to a size below 800px width. When the browser window is make of lesser width than 800px, the canvas with background color #A8A8A8 is on the right of the window, but the problem is, when I move the scroll bar, the canvas should remain on the right of the window. Which does not happen, and that is what my problem is.

How can I solve this issue. What should I do to keep my canvas be on the right=0 all the time.

ActionScript 3.0 :: "mouse Off Canvas" - Go To Frame2 When The Cursor Leaves The Canvas

Feb 24, 2011

Basically I want to go to frame2 when the cursor leaves the canvas. The code below contains no errors when tested but it still does not work.

[Code]...

We know that the function gotoAndStop(frame2); works in multiple situations which means the first 3 line is fine. I don't know if the problem is the MOUSE_LEAVE event or this.stage which i suppose is the identifier for the canvas. I sure that there must be an alternative code for the identifier this.stage or the whole code. Any solution on how to fire the given function in the event when the cursor leaves the canvas?

Flex :: Canvas - 3 - Custom Tab Navigator

Aug 4, 2010

I'm trying to create a custom tab navigator that has to look like. Also, when there's a rollover, the borders of the arrow have to be in blue (like the label in the current tab). For that purpose, I've created a custom component: a hbox containing a label and a canvas with 3 images inside (for the arrow tip that has to change depending on the currentState). Then, I thought of overlapping the components in order to get the blue highlight color (ex: arrow button 3 is over arrow button 4. The image of the arrow tip in button 3 will be transparent outside the arrow, so that we can see the black color of the following button).

I'm now trying to position the components inside the canvas ... but I cannot. After the creationComplete event, I assign the label text and I was calculating the coordonates of the component but it doesn't take into account the label width... -_-'

Flex :: Draw Lines In Canvas?

Dec 13, 2010

I'm trying to draw lines on a canvas object. When the width of the Canvas is less that the width of the line, it draws outside the Canvas over other elements. I read about this problem and I try to resolve using a inner Canvas with a longer height so a scrollbar appears.But I also read that this problem can be correct using a mask but I do not know what is the better way. Which do you recommend?

<mx:Canvas id="panelContentECG" width="100%" height="400" backgroundAlpha="0.5" styleName="miCanvas" borderStyle="solid" cornerRadius="20" borderColor="0xFCFE00" horizontalScrollPolicy="off">

Flex :: Draw String In Canvas?

Dec 30, 2010

I'm trying to draw a String inside a canvas. The text and the position of the String changes pressing differents bottoms. For doing so, I create TextFields which I added to a sprite which I added to a Canvas:

canvas.rawChildren.addChild(spriteNombres);

The first time everything works fine but when I press the bottoms,it does not refresh and appear the old textfields and the new ones.I cant remove the old ones, I try with removeAllChildren and also trying to delete one by one with removeChildrenAt. I do not know if I'm doing something wrong or maybe this is not the best way.

I also try creating bitmapdata and drawing in the sprite inside a rectangle.

var channelName: TextField = new TextField();
channelName.text = channelNames[displaySequence[channel]];
if (channelName.text != null) {

Flex :: Put An Image Inside A Canvas Without It Overflowing?

Aug 13, 2009

I have an Image nested inside a Canvas.

<mx:Canvas>
<mx:Image source="@Embed(source='assets/library.swf', symbol='Waves')" />
</mx:Canvas>

I'd like the Image not to overflow the bounds of Canvas. But when I set width and height on the Canvas, my Image disappears. Canvas also doesn't seem to respect horizontalScrollPolicy.

Seems easy enough, but as the official Flex documentation is down at the moment, I thought I'd turn to SO.
