Re: Appearance id in table cell

 
Hi Ralf

I followed your instructions and overwrite css methods by subclassing qx.ui.table.cellrenderer.Abstract and overwriting _getContentHtml method. I would like to try to get the same effect by overwriting _getCellClass method. My question is: where should I define mySpecialCssClass? Is this a pure css file? If so how to include it into the project?

S pozdravem / Best regards,

Here's a stripped down version of what I use to do that:
I subclass qx.ui.table.cellrenderer.Abstract, and overwrite the _getCellClass method.
There i add my class mySpecialCssClass which I put in an css file of my own.

You can't use appearances in table-cells. I assume this has to do with performance.
But for most needs just a little css class will do thing. And it should perform much faster than using:

_getContentHtml: function( cellInfo ){
  return "<span style=' ... my style hacks '>" +  qx.bom.String.escape( cellInfo.value ) + "</span>"
}

But that too, would work!
But you need to subclass and make your own cellrendered either way.
You assign the cellrenderer like this;

    var tcm = myTable.getTableColumnModel();
    tcm.setDataCellRenderer( i, new myProject.myCellRenderer() );

Where i would be the column-index...
Here is a full-blown cellrenderer example that just adds a css class.
You can also remove the _getCellClassCSS method and put in the _getContentHtml method above to just put style hacks into there directly.

////////////////////////////////////////////
qx.Class.define("myProject.myCellRenderer",{
extend: qx.ui.table.cellrenderer.Abstract,
construct:function(){
////////////////////////////////////////////

  this.base( arguments );

///////////
},members:{
///////////

  _getCellClass:function(cellInfo){
      var cellClass = this.base(arguments, cellInfo);
      if( !cellClass || cellInfo.value == null ) return "";
      return cellClass + " mySpecialCssClass";
   }

////
}});
