This post seems to explain the reason: The y-axis is inverted.

Strange thing is, however, if you place a cone on the scene, it is pointing upwards as you would expect when using a normal (not-inverted) y-axis. Makes it all a bit confusing, but now you know…

So far, I’m quite pleased about it and donated $20,-.

Like:

 var topPlane:Plane = new Plane({ownCanvas:true});
 topPlane.filters.push(new BlurFilter(8, 8));

If you don’t read Spanish, this is a summary of the problem and the solution:

Apparently, it sometimes happens that your account is not registered as an ‘Admin’ account. You have find the id of your user account in the table ‘user’. Then find the corresponding row in the table ‘project_user” and set the field ‘pru_role’ to ‘7′.

I superficially read some articles on how people implemented their version. I didn’t find a ready to use component, so I decided to make one myself as a challenge.

My component behaves like a Canvas with an HScrollBar and the idea is really simple:
There is an inner Canvas and an outer Canvas. The inner Canvas contains the content you want to scroll. The HScrollBar of the inner Canvas is hidden. The outer Canvas creates a proxy HScrollBar and positions this over the hidden HScrollBar. Now the user interacts with the proxy HScrollBar and each change is copied to the HScrollBar of the inner Canvas. And the trick now is to use an easing function when you copy the proxy Scroll thumb position to the hidden Scroll thumb position.

Here you see both HScrollBars on top of each other. The upper HScrollBar is the original scrollbar of the inner Canvas. The lower HScrollBar is the proxy version.

And if we hide the upper HScrollBar and shift the lower HScrollBar upwards to take its place, we get this:

While the principle seems to work, the feeling is not perfect. It’s not as nice as it is on an iPhone. So I’ll have to work on that.

Furthermore, I want to combine two behaviours:

• Slow scrolling with a behaviour almost without easing
• Stepwise/fast scrolling with a strong apparent easing

I’ll continue working on this and post improvements.

Example of an embedded image:

[Embed(source="assets/image.jpg")]
[Bindable]
private var myImage:Class;

An easy way to do this is of course:

var imgClass:Class;
switch (imageName) {
    case 'myImage':
        imgClass = myImage;
        break;
   case 'otherImage':
        imgClass = otherImage;
        break;
}

But there is an easier solution. Say that the image is embedded in MyView.mxml, then you can use this statement in MyView.mxml;

var imgClass:Class = getDefinitionByName(getQualifiedClassName(this)+'_'+imageName) as Class;

If you use the debugger, you’ll see that imgClass looks like: MyView_myImage. Or more specifically, if MyView.mxml is located in package, e.g. ‘views’, then imgClass = views.MyView_myImage;

public class BindableDictionary extends ObjectProxy
	{
		private var _state:Dictionary;
		public function BindableDictionary() {
			_state = new Dictionary();
			super(_state);
		}

	}

Now you can set eventlisteners on the wrapper:

var bd:BindableDictionary = new BindableDictionary();
bd.addEventListener(PropertyChangeEvent.PROPERTY_CHANGE, handler);

I haven’t done full functional testing on this, but it seems to work fine so far.

The project presents some excellent effects, especially for use with viewstacks.

Update april 14, 2010:
The button now works!

Step 1:
Install Syntax Highlighter Evolved.

Step 2:

Create or edit a post and select the ‘HTML’ tab on the top right.

Step 3. Copy your source code from your html-editor and paste into the post.

Step 4. Put code tags around the pasted code:

If you have an HSlider and the right side of the slider is close to the right side of the stage, the tooltip may ‘walk off’ the screen. See the following image.  The grey background is the standard Flex Halo background. The green background is the color of my desk top.

This does not happen at the left side of the stage. If you drag the thumb to the left end of the slider, you see some smart things happening: the tooltip gets stuck at stage.x = 0;

I set myself to solve this problem and came up with a solution, which may also be called a hack. It uses mx_internal namespace, which means that it may not work in future versions of the Flex SDK. But I don’t know a better way. You do? Please let me know!

Step 1. Extend the SliderDataTip class:

package cbs.components.sliderClasses
{
	import flash.geom.Point;

	import mx.controls.sliderClasses.Slider;
	import mx.controls.sliderClasses.SliderDataTip;

	public class MySliderDataTip extends SliderDataTip
	{
		private var _slider:Slider;

		public function MySliderDataTip(owner:Slider):void {
			_slider = owner;
		}

	 	override protected function updateDisplayList(w:Number, h:Number):void {
			super.updateDisplayList(w,h);
			// Check if the tip overlaps the right side of the slider

			if (_slider) {
				var sliderPos:Point = _slider.localToGlobal(new Point(0, 0));
				if (this.x + w >= sliderPos.x + _slider.width) {
					this.x = sliderPos.x + _slider.width - w;
				}
			}
		}
	}
}

Extend the HSlider and override the onThumbPress function.

override mx_internal function onThumbPress(thumb:Object):void {
	// Hack this function, to be able to generate our own slidertip and
	// set a parameter.
	if (!dataTip) {
		dataTip = MySliderDataTip(new MySliderDataTip(this));
		systemManager.toolTipChildren.addChild(dataTip);

		var dataTipStyleName:String = getStyle("dataTipStyleName");
		if (dataTipStyleName)
		{
			dataTip.styleName = dataTipStyleName;
		}
	}
	super.onThumbPress(thumb);
}

That’s it!
