Re: Help on compiling notebook example

[Chun Yang <achunyang2010 gmail com>]

Hi All,

Sorry again. I kept pressing some button I was not aware and sent this email again.

Here are my question:
1. What are the warning (highlighted in green) after I started to run the program?
2. What is the reason for me to get all the warnings (in blue) and the error (in red)? I can not continue the program due to the error.
3. How do I fix the error?

Thanks,
Chun

Sorry I pressed the wrong button.

Let me continue.

I have the following code:

In my .h file, I have:
  class CGraphView : public Gtk::ScrolledWindow
  {
    ..... .....
    static Gtk::Button _pageMenuLabel;
  };

In my .cpp I have:

Gtk::Button CGraphView::_pageMenuLabel("X");

I planned to use _pageMenuLabel as an page to Gtk::Notebook as in:
  append_page(* graph_view, graph_view->_pageTabLabel, CGraphView::_pageMenuLabel);
After I compile and  run gdb with breakpoint set on the above line, I got the following.

I got two questions to asked
