And the first time I am using this function is in this code: data1 = gtk_label_new( NULL ); gtk_label_set_markup( GTK_LABEL( data1 ), m_data1->str ); g_free( m_data1->str ); gtk_table_attach( GTK_TABLE( table ), data1, 0, 1, 1, 2, GTK_EXPAND, GTK_EXPAND, 0, 0 ); gtk_widget_show( data1 ); Thank you.
