Access Signal of Class Member Variable

[starkid]

I have a subclass of QMainWindow that includes a QProgressBar as a member. The subclass also contains an instance of another class called articlePage, which contains a QWebView. I want to connect the loadProgress signal of the QWebView to the setValue slot of the progress bar.

class articlePage;
 
class appWindow	:	public QMainWindow
{
	Q_OBJECT
 
	public:
		appWindow(QWidget* parent = 0);
 
        private: 
               articlePage *firstPage;
              QProgressBar *webLoad;

class articlePage;

class appWindow	:	public QMainWindow
{
	Q_OBJECT

	public:
		appWindow(QWidget* parent = 0);

        private: 
               articlePage *firstPage;
              QProgressBar *webLoad;

To copy to clipboard, switch view to plain text mode 

class articlePage	:	public QWidget
{
	Q_OBJECT
 
	public:
		articlePage(QWidget* parent=0);
		QWebView *wordSearch;

class articlePage	:	public QWidget
{
	Q_OBJECT

	public:
		articlePage(QWidget* parent=0);
		QWebView *wordSearch;

To copy to clipboard, switch view to plain text mode 

Placing

connect(firstPage->wordSearch, SIGNAL(loadProgress(int)), webLoad, SLOT(setValue(int)));

connect(firstPage->wordSearch, SIGNAL(loadProgress(int)), webLoad, SLOT(setValue(int)));

To copy to clipboard, switch view to plain text mode 

in appWindow.cpp gives a segmentation fault. What is the proper way to access wordSearch's signals?
