Description

Hi all,

I use a WTableView to implement a logbook with row colors set according to event types.

Cell content is set with this code:

LogBook::LogBook(int rows, int columns, Wt::WObject *parent) : VirtualModel(rows, columns, parent) {
    List_reset( 0 );
    Wt::WApplication::instance()->styleSheet().addRule("option.myclass","background-color: red;");
}

boost::any LogBook::data(const Wt::WModelIndex& index, int role) const {
    int color;
    switch (role) {
        case Wt::DisplayRole:
            return Wt::WString(List_cell(0, index.row(), index.column(), &color));
/*
        case Wt::StyleClassRole:
            return Wt::WString("option.myclass");
            break;
*/
        default:
            return boost::any();
        }
}

The problem is that i dont know how to set the background color. I guess i have to return some clever information for the Wt::StyleClassRole role but i cant get it to work.

Thank you for your Help.

Regards,

Olivier

Hey oliver,

This should work provided you remove the '.' from the class name --- that's not allowed.

(The '.' is an operator in a style class selector to combine class names, see http://www.w3.org/TR/CSS2/selector.html#class-html)

Wt::WApplication::instance()->styleSheet().addRule(".option-myclass","background-color: red;");

        case Wt::StyleClassRole:
            return Wt::WString("option-myclass");
            break;

Regards,

koen
