Subject: Re: [fltk.general] Getting text into the top-left "cell" in Fl_Table_Row

In the shown example, it’s the place to the left of where it says “Date” and above the place where it has “2925”. I would like to write into there.

    Oh, that little area is neither cell nor header.. that's a perfect use for CONTEXT_ENDPAGE.
    Here's how to write to that area, shown by drawing an "X":

      case CONTEXT_ENDPAGE: {                   // after page headers/cells are drawn..
        // Draw black 'x' in the dead area
        int X1=x(), Y1=y(), X2=x()+row_header_width(), Y2=y()+col_header_height();
        fl_color(FL_BLACK);
        fl_line(X1,Y1,X2,Y2);
        fl_line(X1,Y2,X2,Y1);
        return;
      }

Thanks Greg,

Looks like I had originally tried to display the text in the top-left of the window.

I had to tweak the code slightly to get the box to line up with the column headers:

       case CONTEXT_ENDPAGE:

       {

              // Code trying to write text into the top-left corner

              // Set the font for the header header

              fl_font(fl_font() | FL_ITALIC, fontsize_);

              // Set the col header row header crossing point

              fl_color(col_header_color());

              int X1 = x() + Fl::box_dx(box());

              int Y1 = y() + Fl::box_dy(box());

              int W1 = row_header_width();

              int H1 = col_header_height();

              fl_draw_box(FL_BORDER_BOX, X1, Y1, W1, H1, col_header_color());

              // Text color

              fl_color(FL_BLACK);

              fl_draw("QSO No.", X1, Y1, W1, H1, FL_ALIGN_CENTER);

              return;

       }

Regards Phil.
