Re: How to style specific cells in CellTable depending the value of that cell (GWT)?

Wouldn't it be easier to first convert your List<Integer[]> into a Map<Integer, Map<Integer, Integer>> (or a a Guava Table) and then in your column's getCellStyleNames (assuming a Table here, for readability):

Integer colorLevel = intersections.get(context.getIndex(), context.getColumn());

if (colorLevel != null) {

  switch (colorLevel.intValue()) {

  case 1:

    return myResource.css().sufferingColorLevel1();

  …

  }

}

return null;

Hi, i think i can just loop over the List<Integer[]> rowColIntersectionList and then loop over the text of each cell & append a control String like "colorLevel=1*" to the cell value, then in the IndexedColumn i just need to do

@Override
public String getCellStyleNames(Context context, List<String> object) {
  String value=object.get(index);
   
  if (value!=null && !value.trim().equals("")) {
   if(value.indexOf("colorLevel=1*")>=0){
      return myResource.css().sufferingColorLevel1();
   }
   else if(value.indexOf("colorLevel=2*")>=0){
      return myResource.css().sufferingColorLevel1();
   }
   else if(value.indexOf("colorLevel=3*")>=0){
      return myResource.css().sufferingColorLevel2();
   }
   else if(value.indexOf("colorLevel=4*")>=0){
      return myResource.css().sufferingColorLevel2();
   }
   else if(value.indexOf("colorLevel=5*")>=0){
      return myResource.css().sufferingColorLevel2();
   }
   
 }
 return null;
}

@Override
public String getValue(List<String> object) {
  String value=object.get(this.index);
  if (value!=null && !value.trim().equals("")) {
   if(value.indexOf("colorLevel=1*")>=0){
      return value.replace("colorLevel=1*", "");
   }
   else if(value.indexOf("colorLevel=2*")>=0){
      return value.replace("colorLevel=2*", "");
   }
   else if(value.indexOf("colorLevel=3*")>=0){
      return value.replace("colorLevel=3*", "");
   }
   else if(value.indexOf("colorLevel=4*")>=0){
      return value.replace("colorLevel=4*", "");
   }
   else if(value.indexOf("colorLevel=5*")>=0){
      return value.replace("colorLevel=5*", "");
   }

  }
  return value;
 
}

However i ran into another problem, that is Not all text in cell needs controlString. For example:

String originalText1="iPhone";  String controlString= "colorLevel=2*";  String newText1 =controlString+originalText1; //ie newText=colorLevel=2*iPhone    String originalText2="iPhone 3G"; // this originalText2 has no controlString  String newText2="iPhone 3G";    String originalText3="colorLevel=2*aaa"; // this has no controlString but its front is exactly the same as controlString  String newText3="colorLevel=2*aaa";    String originalText4="colorLevel=2*bbb"; // has controlString but at the same time its front is exactly the same as controlString  String controlString= "colorLevel=2*";  String newText4 =controlString+originalText4; // ie newText4=colorLevel=2*colorLevel=2*bbb

 

Then i need a function to read all these new text. This function need to trip off the controlString to get the original.

So my question is, how to encode the original text in such a way that when we trip out the front string of the new text we won't affect the original text?

Actually, Column#getCellStyleNames also has everything you need; if you need to add the style to the table cell, rather than a "content container" (<div> or whatever) within the table cell.

I have the feeling that it would be easier to write a custom cell (possibly extending an existing one) and in its render method decide if it should add a bold, bolder or extrabold css class to the output.

Inside Cell.render() you have access to everything you need to make that decision (row index, column index, column value).
