Description
CalcKeyPress is a method used to implement the OnKeyPress event handler for the TCalculatorForm instance where the panel is displayed.
Sender is the object instance (TCalculatorForm) for the event
notification.
Key is the character value for the key (or button) for the
notification. If Key is the caption for one of the buttons on the panel, its
Click method is called. Otherwise, the private CalcKey method is called to
apply the Key value.
CalcKeyPress is called by a TCalculatorForm instance when its OnKeyPress event handler is executed.
