Flex Component: PanScrollingCanvas

I just found an awesome Canvas with Panning Scrolling .....with a nice effect.


The PanScrollingCanvas is a Flex container that scrolls its children on mouse move. Fully skinnable buttons appear when hovering over the container. The behavior of those buttons can be customized on the client side, by listening to events that this container will fire on button rollover, rollout, and click.


source

Drawable Canvas

The component itself is a transparent canvas (background alpha = 0), which means that you can put it on top of anything you like in order to be able to draw anywhere.
On the mouse down event I add a mouse move listener which adds points to an array, and I remove the listener on the mouse up event. These arrays are the lines.
In the updateDisplayList method I loop through all the held arrays and draw them onto the canvas.

Flex FlowBox Container

Awesome container i've been looking for!!!

A container which would lay its child components out in a horizontal manner like an HBox, but unlike an HBox, it needed to wrap the child components into a new row when they exceeded the available width. If the available height was exceeded, the container should then grow downwards if the height property has not been set to a constrained value. If the height is constrained, then scrollbars should appear

Smoothing resized distorted images in flex

Problem: Images when loaded into flex look blurred, distorted or poor quality.

Solution: Fixing the loaded images using smoothing .


Hi guys , i think we all come across the problem of loading images into flex and disappointed by the way they look blurred or distorted in flex. By default images loaded into flex are not smooth.
I have written a small function that can be called on "complete" event of image loader component and rest you dont need to worry it takes care all . Above picture shows how clean image looks after after applying smoothing code .It even works if the image is zoomed or resized later .


//Mxml starts here




//call this function from where ever you need Image Smoothing .Code by http://askmeflash.com
private function smoothImage(evt:Event):void{
var myBitmap:Bitmap = ((evt.target as Image).content as Bitmap);
if (myBitmap != null) {
myBitmap.smoothing = true;>
}
}
]]>








//mxml ends here

Removing the theme color from the Flex TileList

I have been looking for the solution ... Finally found it while searching the net.
Saved alot of time ...

Here it goes:

There have been a number of occasions when the designs for a UI implements some kind of grid layout to display its items. This is fairly simple to implement in flex by utilising the Flex TileList component. However more often than not the List's item renderers are required to look after their own states. In this case the TileLists Indicators are no longer required.

I have found the easiest way to remove the TileLists indicators is to set the ThemeColor to the background color of whatever the List is being displayed on. But what happens if the background contains an image or has a transparency value?

To do this you need to override the TileLists drawSelectionIndicator and drawHighlightIndicator methods.

**************************************************************

override protected function drawSelectionIndicator(
indicator:Sprite, x:Number, y:Number,
width:Number, height:Number, color:uint,
itemRenderer:IListItemRenderer):void
{
/* we don't need to do anything in here*/
}
override protected function drawHighlightIndicator(
indicator:Sprite, x:Number, y:Number,
width:Number, height:Number, color:uint,
itemRenderer:IListItemRenderer):void
{
/* we don't need to do anything in here*/
}

*************************************************************

Notice that the body to the above methods are empty. This is because we don't want the indicators to draw anything behind the renderers when the state changes.

Now just don't forget to cater for this inside your TileList's item renderer else the user will get confused as to which item is selected and which item their mouse is over. We wouldn't want that would we :)





Thanks for the solution
