Changing tables background-color depending on a value
Hi list,
I'd like to change the background-color of a table row depending on a value that
is displayed in the table.
I am showing a table with one row for each day in the current month, to
highlight weekends saturdays and sundays should have a different
background-color.
Usually I am using Decorator for handling value-objects, but I don't see a way
how to change the background-color of the table-cells.
Is there a way to do this?
Thanks in advance
SVen

Or you could use jQuery to do the job in the browser only: if the
coloring criteria can be deduced purely from the values. E.g.:
http://www.exforsys.com/tutorials/jquery/jquery-three-color-alternating-pattern.html
e.g. in the text from the above URL, in the second code sample, at:
"//Code to be applied to each element in the matched set. "
you can put your own JavaScript code that checks if those values are
met, and than apply color only to those rows:
----------------------
$(this).addClass('myColorForThoseValues');
----------------------
and of course, you need to define in your CSS the
".myColorForThoseValues" class.

Hi Sven,
Lets try and incorporate this feature in the next release, 2.2.0. Can you open a JIRA and add your
implementation to the issue?
kind regards
bob

Re: Changing tables background-color depending on a value

Hi guys,
I'd like to restart the discussion whether it should be possible to be able to
change column attributes from within a Decorator.
I've been playing around with jQuery a lot, lately and I think it would
be great
if I could set a columns class from java inside a decorator, based on it's
value, or some other (not displayed) value of the object.
Of course these changes shouldn't change the signature, which would break
existing code, but I think my draft (ColumnDecorator) would be a good
solution.
kind regards
SVen

Re: Changing tables background-color depending on a value

I've been thinking about this too.
A possible solution, that won't have any impact on existing apps, would
be to create an abstract class (ColumnDecorator) like this.
public abstract class ColumnDecorator implements Decorator {
private Column column;
public Column getColumn() {
return column;
}
public void setColumn(Column column) {
this.column = column;
}
public abstract String render(Object object, Context context);
}
Then you could check if the Column has a ColumnDecorator set and call
the setter.

Re: Changing tables background-color depending on a value

I think it might be a problem if we change the signature of Decorator as it will break existing
applications and Decorator is used by Tree and PropertySelect as well.
Will have to think a bit how we can introduce attribute manipulation at the cell level without
impacting existing apps.

Or a custom Column. At least the method Column#renderTableData would have to be adapted to add
attributes on a per cell basis.

Hi Sven,
You will probably need to subclass table to do this.
