Hello, Every One
    I found a possible bug of gtk2forpascal, but I don't know how to fix it.
    Let's create a new gtk widget:
>>>>
type
  PGtkMyWidget = ^TGtkMyWidget;
  ^TGtkMyWidget;= record
    hpaned           : TGtkHPaned;
    tree_sw          : PGtkScrolledWindow;
    tree_view        : PGtkTreeView;
    text_sw          : PGtkScrolledWindow;
    text_view        : PGtkTextView;
  end;//TGtkMyWidget;
<<<<
    What ever the other code about TGtkMyWidget is, it doesn't matter.
    Then new an instance of TGtkMyWidget, and put it in a window, put a button in the window, and connect the button's click signal to a callback function, in this function you try to access the text_view of TGtkMyWidget. Such as:
  gtk_text_view_set_editable(the_widget^.text_view,TRUE);
  Then the program crashes. I also find in many cases, some codes which attempt to access the member of a widget cause the program to crash. Perhaps the problem is the difference of C<--->Pascal programming and memory accessing. I don't know how to fix it. Can anyone find a solution?
