How to set Default Text Statement in QComboBox

[rawfool]

How to set a default text to QComboBox. For Eg., "Select an option", as shown below

Before :
-----------------------
|Select an option | V |
-----------------------

On Click :
-----------------------
|_____________ | V |
|Option 1 |
|Option 2 |
|Option 3 |
-----------------

Try out this:

void QComboBox::setEditText ( const QString & text )

void QComboBox::setEditText ( const QString & text )

To copy to clipboard, switch view to plain text mode 

You might have to subclass the QComboBox to achieve the deleting when the user selects, I am not sure.
Might be doable with the signals:

void 	editTextChanged ( const QString & text )

void 	editTextChanged ( const QString & text )

To copy to clipboard, switch view to plain text mode 

and/or

void 	activated ( int index )
void 	activated ( const QString & text )

void 	activated ( int index )
void 	activated ( const QString & text )

To copy to clipboard, switch view to plain text mode 

I am not sure if this works, but it might be worth a try.
