What is difference between SIGNAL(currentTextChanged(const QString&)) and Signal(itemSelectionChanged) for QListWidget , when to use which one

[mrjj]

void QListWidget::currentTextChanged(const QString & currentText)
This signal is emitted whenever the current item changes.

void QListWidget::itemSelectionChanged()
This signal is emitted whenever the selection changes

Edit Signal or Selected Signal:

So often you will use both.
