Sorry. I have tried again. 

I display text file on text widget by useing gtk_text_insert() 
like a bellow. 

void
file_selection_ok(widget, fs)
GtkWidget *widget;
GtkWidget *fs;
{
    unsigned char *buf;

    buf = get_file(gtk_file_selection_get_filename(GTK_FILE_SELECTION(fs)));
    gtk_widget_destroy(fs);

    gtk_text_insert(GTK_TEXT (text), NULL, &text->style->black,NULL,
                     buf, -1);
    gtk_text_thaw(GTK_TEXT (text));
}


After diplaying a text file, I reopen file sellection window 
(gtkfilesel widget) from menu to display a new text file by
calling file_sellection_ok(). So, The _new_ text should add
to the _old_ text on text widget. I want to avoid this by 
removing the _old_ text from text widget.

Could I make my state understand to you ?
