ImageCellRendere

[Pluda]

Hello,

Need some help here,

I've one imageCellRenderer to use with a datagrid like this

ImageCellRenderer.as

import mx.core.UIComponent;
class imageCellRender extends UIComponent {
   //
   var img:MovieClip;
   var url:String = "pics/icones_peq/";
   var listOwner:MovieClip;
   var getCellIndex:Function;
   var getDataLabel:Function;
   //      
   function setValue(str:String, item:Object, sel:Boolean):Void {
      img.loadMovie(url+""+item[getDataLabel()]+"?"+getTimer());
   }
}

then im my movie I use

column = _root.mc_grid.grid.getColumnAt(0);
column.width = 70;
column.cellRenderer = "imageCellRender";


It works almost fine, the icons apear in my datagrid, but somehow, they are loaded plenty of times and not just once.

Where can the problem be?

Thanks,

Pluda

The setValue fires constantly, in the rollOver/rollOut, scroll, etc (just add some trace to check) Probably you want to check if it's there prior to load, i.e:

if(img._width<1)  img.loadMovie(url+""+item[getDataLabel()]+"?"+getTimer());

Sorry for lepping posting, but I'm finding my errors and I don't see how to solve them.

Using the ImageCellRendere, I can use images in my datagrid, but when removing rows, all the data in the choosen row disapears, but the images don't.

So the question is:

When using imageCellRenderer, is there any way of return a reference of the instance name of the movieclip the datagrid used to load the image, so we can use removeMovieClip to remove her if needed?

This may be complicated, I'm soory for my english, I can't describe it better.

I'm posting an example code

to add some content to the grid

var refer:Object = {Product:""+pic+"", Qt:""+_quant_.text+"", Ref:""+ref+"", Preço:""+preco+""};
_root.mc_grid.grid.addItem(refer);


to remove a selected row

que_produto.click = function() {
   //
   var numero:Number = _root.mc_grid.grid.selectedIndex;
   var foto:String = _root.mc_grid.grid.getItemAt(numero).Product.img;
   trace(foto);
   _root.mc_grid.grid.unloadMovieNum(foto);
   _root.mc_grid.grid.removeItemAt(_root.mc_grid.grid.selectedIndex);
   //
};

this does remove the select row, but doesn't unload the image.


Did I make myself untherstand?


Thanks a lot for help :-)

Try the HTMLCellrenderer, it can load images plus other things: http://philflash.inway.fr/dghtmlrd/dghtmlrd.html
