Clear the cairo text in gtk_window … here is a solution to the problem.
Clear the cairo text in gtk_window
I have questions about the Cairo text.
I wrote some lines in 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 the function that writes the text multiple times, the lines overlap.
Is there any way to refresh the previous text?
Thanks!
Solution
You have to overlay the text with a background color 🙂
