RE: [flexcoders] specifying measuredWidth/measuredHeight in a skin

Hi Mike, thanks for the response. I do have a solution now, based on Dirk's example (http://www.richinternet.de/blog/index.cfm?mode=entry&entry=ADD4FDD1-9B48-BFBC-2A70F3C57EBC6892), but I would be interested in knowing what I was doing wrong. I was doing something I saw in the framework for Application, and subclassing ProgrammaticSkin and using it in CSS as a background-image. The skin would have to have the measuredWidth/measuredHeight, as previously mentioned, and here's the a simplified version of the updateDisplayList() method:

override protected function updateDisplayList(w:Number, h:Number):void

{
super.updateDisplayList(w, h);

// FIXME: override Application to add styles for all values below, then getStyle() for each
// one and set in CSS

var g:Graphics = graphics;
g.clear();

// set width and height to dimensions we want for this gradient

   w = 916;
  h = 16;
    var fillColors:Array = [0xF7F7F7, 0xD5D5D5];
    var fillAlphas:Array = [1, 1];
    drawRoundRect(x, y, w, h, null, fillColors, fillAlphas, verticalGradientMatrix(x, y, w, h));

}

And this works fine, but again only if the measuredWidth/measuredHeight is set. So after seeing Dirk's code, I tried changing one skin over to extend HaloBorder, not set the measuredWidth/measuredHeight, and then use the skin in CSS as a border-skin. This works, I'm happy to say. It does feel a little strange to me, that I'm using something called "border-skin" but I'm doing things in the middle of a canvas. Is this part normal or should I be using a background-image?

This turned into a longer message than I thought! I'm starting to get into this whole building-a-Flex-app thing. :) -Brian

Hi Brian,

This dosn't make sense...

What are you subclassing for the skin class?

I use ProgrammaticSkin and RectangularBorder all the time and have never specified measuredWidth or measuredHeight in a skin. I get none of the things you are talking about.

Are you using an image or drawing API in the skin?

If it is a borderSkin style are you subclassing RectangularBorder? For the borderMetrics. Can you give an example, I am sure I could nail this one.

Peace, Mike

Ah, my first flexcoders post as a Flex developer. I feel like I should
be getting my cloak and learning a secret handshake right now.

Is there a way to not specify the measuredWidth and measuredHeight in a
skin? I don't like having to hardcode a width and height there, as I
currently have to do.

For more details, this is an application that is using absolute
positioning, and the skins are on Canvases. If I don't specify the
measured width and height in the skin, then the drawRoundRect() doesn't
draw from the correct position, and the passed-in width and height from
updateDisplayList() doesn't seem to help with this fact. Am I missing
something here?

Thanks for any pointers, Brian
