Wt

hey, Wt group:

I want to apply a concise style on a table like below:

    void StatisticTable::applyConciseStyle(bool last_row_border) {

        int row_c = table_->rowCount();
        int col_c = table_->columnCount();

        WBorder main_b;
        main_b.setWidth(WBorder::Explicit, WLength(2));
        main_b.setStyle(WBorder::Solid);
        main_b.setColor(WColor("green"));

        WBorder sub_b;
        sub_b.setWidth(WBorder::Explicit, WLength(1));
        sub_b.setStyle(WBorder::Solid);
        sub_b.setColor(WColor("green"));

        for(int tcol = 0; tcol < col_c; ++tcol) {
            table_->elementAt(0, tcol)->decorationStyle().setBorder(main_b, Top);
            table_->elementAt(1, tcol)->decorationStyle().setBorder(sub_b, Top);
            if(last_row_border)
                table_->elementAt(row_c-2, tcol)->decorationStyle().setBorder(sub_b, Bottom);
            table_->elementAt(row_c-1, tcol)->decorationStyle().setBorder(main_b, Bottom);
        }

, but the grind reported below:

I changed some code like below, every thing is ok:

            if(last_row_border)
                table_->elementAt(row_c-1, tcol)->decorationStyle().setBorder(sub_b, Top);
            table_->elementAt(row_c, tcol)->decorationStyle().setBorder(main_b, Top);

I think whether the setBorder(WBorder border, WFlags sides = All) does not work? it is fine in wt-3.1.9, in wt-3.1.10 I must change the setBorder(main_b, Bottom) to setBorder(main_b, Top).

Thanks

Best Regards
