updating text in QTextEdit [SOLVED]

[me_here_me]

Hi
I want to update the text in a QTextEdit upon the occurance of a specific event. Following is the snapshot of my application

QTextEdit *metaDataText;                   // this is the text box to be updated
 
Window::Window(QWidget *parent) : QWidget(parent) {      // constructor for the main window class
               metaDataText = new QTextEdit;                           // initializing the text box 
               metaDataText->setText(MetaData::returnMetaData());      // puttin in initial values
}

QTextEdit *metaDataText;                   // this is the text box to be updated

Window::Window(QWidget *parent) : QWidget(parent) {      // constructor for the main window class
               metaDataText = new QTextEdit;                           // initializing the text box 
               metaDataText->setText(MetaData::returnMetaData());      // puttin in initial values
}

To copy to clipboard, switch view to plain text mode 

I want to display when the text in the MetaData class changes.
So when the text changes in the MetaData class, a signal (triggerMetaDataUpdate) is issued, for which a slot is present in the window class as given below:

void Window::triggerMetaDataUpdate(){             // slot for the signal
	metaDataText->setText(MetaData::returnMetaData());         // call to update, which does not update:(
	update();
}

void Window::triggerMetaDataUpdate(){             // slot for the signal
	metaDataText->setText(MetaData::returnMetaData());         // call to update, which does not update:(
	update();
}

To copy to clipboard, switch view to plain text mode 

but this thing does not update the text in the QTextEdit.

can someone please help me do this correctly?

thanks
