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

Can you verify that the slot indeed gets called and that MetaData::returnMetaData() returns changed data?
