[SOLVED] Clear cairo text in gtk

Clear cairo text in gtk_window

I'm have a trouble with a cairo text. I write some lines in a gtk_window:

cr = gdk_cairo_create(window->window);
        cairo_set_source_rgb(cr, 255, 255, 255);
        cairo_select_font_face(cr, "Sans", CAIRO_FONT_SLANT_NORMAL, CAIRO_FONT_WEIGHT_NORMAL);
        cairo_set_font_size(cr, 14.0);

        cairo_move_to(cr, 90.0, 85.0);
        cairo_show_text(cr, "Terror");
        cairo_set_font_size(cr, 12.0);
        cairo_set_source_rgb(cr, 30, 254, 145);
        cairo_move_to(cr, 90.0, 105.0);
        cairo_show_text(cr, "Underdogs");
        cairo_move_to(cr, 90.0, 120.0);
        cairo_show_text(cr, "Disziplin");
        cairo_destroy(cr);

The problem is that this text should be dynamic, but if I call more than one time the function that writes the text, lines is overlapped.

Is there any method that flushes the previous text?

Thanks!

Solution

You have to overwrite the text with the background color :)
