Re: A packaged resource that has a variable image based on
component value
Okay, I will see if I can figure out how to do that. Currently, I am
@Override-ing the getCellCssClass and seeing if I can vary the css resource
depending on the corresponding columns value as that is the only idea I had
currently on how I could possibly do this.

This is what I ended up with to include a solution for my colored circle
images in case someone else finds the need for such a solution. I am
assuming it was a reasonable way to go:
...
/*
* Checkbox column for the color blind
*/
if (colorblind) {
columns.add(new CheckBoxColumn("checkBox"));
}
/*
* Check Item State column
*/
columns
.add(new PropertyColumn(new ResourceModel("state"), "state",
"state") {
private static final long serialVersionUID = 1L;
@Override
public String getCellCssClass(IModel rowModel, int rowNum) {
return "state";
}
@Override
public boolean isEscapeMarkup() {
return false;
}
@Override
protected IConverter getConverter(final Class<?> varType) {
return new IConverter() {
// serialVersionUID.
private static final long serialVersionUID = 1L;
public Object convertToObject(String value,
java.util.Locale locale) {
// TODO Auto-generated method stub
return null;
}
public String convertToString(Object value,
java.util.Locale locale) {
String color = "white";
switch ((Integer) value) {
case 0:
color = "black";
break;
case 1:
color = "gray";
break;
case 2:
color = "red";
break;
case 3:
color = "yellow";
break;
case 4:
color = "blue";
break;
case 5:
color = "green";
}
if (!colorblind) {
return "[lt]img src=\"images/".concat(color).concat(
"-circle.png\"").concat(" alt=\"").concat(
value.toString()).concat("\[gt]");
} else {
return value.toString();
}
}
};
}
}.setInitialSize(3).setSizeUnit(SizeUnit.EM).setResizable(false)
.setReorderable(true).setHeaderTooltipModel(
new Model("State of the check item")));
...
where [lt]=<
and [gt]=>
Not sure how to address this problem when replying...
I stored all my image files under webapp/images. I am a beginner with Wicket
but this seemed to work fine for me and I can see it coming up for someone
else so figured I would share my outcome.

Seems to have chopped of my return line, which was:
return "(less than)font style=\"background-color: " +
color + "\"(greater than)" + value + "(less than)/font(greater than)";
(less than) = <
(greater than) = >
Hope it works this time

So I decided that I am not experienced enough yet with Wicket or using
inmethod DataGrid to try to do images but would like to at least change the
background color based on an integer value. This is what I did but still
think it is somewhat lame and probably there is a much better approach:
For my column that contains an Integer in its model I did the following:
@Override
public boolean isEscapeMarkup() {
return false;
}
@Override
protected IConverter getConverter(final Class<?> varType) {
return new IConverter() {
//serialVersionUID.
private static final long serialVersionUID = 1L;
public Object convertToObject(String value,
java.util.Locale locale) {
// TODO Auto-generated method stub
return null;
}
public String convertToString(Object value,
java.util.Locale locale) {
String color = "white";
switch ((Integer) value) {
case 0 : color = "gray";
case 1 : color = "black";
case 2 : color = "red";
case 3 : color = "yellow";
case 4 : color = "blue";
case 5 : color = "green";
}
return "" + value + "";
}
};
}
