Print CSS

Hi,

I got WebTabs print better (some fiddling still needed) by copying the css..
methods to cssPrint.. methods. I love Aida's naming conventions!

The legends of a WebChart (at least if printed outside the chart) seem
to use a JS generated screen css to set the colour. They print without
colour.

The screen css seems generated in WebStyle>>protoChartJs after
legendColorBox.

So how do I generate the print css dynamically? And wouldn't that be a
bug to report to the protoChart people?

Thanks,

Herbert                          mailto:[hidden email]

By adding a cssPrint method which builds CSS dynamically instead of just
returning the static text.

Another way is inline CSS, using WebElement style: 'put a style
definition here'

But I don't know id this can help in your case ...

Hi Janko,

IMHO this can't work as the legend has a rectangle for every line
repeating that line's colour. And they all share the same class.

Yes but I need to put a print style there. Maybe I'm on the wrong path
as I actually don't know the difference between a print style and a
screen style. And how to set a pritnt style dynamically. Seems I have
to spend some time learning CSS.

To see the problem just print the line chart of the WebChartDemo to
see that the labels have no colour and are printed in a position
different from their screen position.

The latter is no problem to me because I need the labels outside.

This can be done with a slightly changed WebChartDemoApp>>lineChartElement.

lineChartElement
        | e c container|
        e := WebElement new.
        container := WebElement new.
        container registerId.
        e addTextH2: 'Line chart example'.
        c := WebChart new
                addData: self observee data1 label: 'label 1';
                addData: self observee data2 label: 'label 2';
                addData: self observee data3 label: 'label 3'.
        c lines show: true;
                showShadow: true.
        c legend show: true.
        (c optionsAt: #legend) container: container id.
        e  add: container; addBreak.
        e newRow.
        e add: c.
        ^e

Just curious, do you not need to print WebCharts with legends or have
you solved that in a completely different way?
