Use of gtkmm function g_timeout_add

Could someone please show me an example of how to use the Gtkmm function g_timeout_add. I tried calling it like this: g_timeout_add(100, &MainWindow::callbackFunc, processed); but I get the error:

error: cannot convert ‘gboolean (MainWindow::*)(std::__cxx11::string) {aka int (MainWindow::*)(std::__cxx11::basic_string<char>)}’ to ‘GSourceFunc {aka int (*)(void*)}’ for argument ‘2’ to ‘guint g_timeout_add(guint, GSourceFunc, gpointer)’
 g_timeout_add(100, &MainWindow::callbackFunc, processed);

And if I try to call it without the & (g_timeout_add(100, MainWindow::callbackFunc, processed);), then I get the following error:

error: invalid use of non-static member function
 g_timeout_add(100, MainWindow::callbackFunc, processed);

The callback function is defined as: 

gboolean callbackFunc(std::string data);
