Flick Gestures - HP TouchSmart 9100 - Business PC Application Manual

The following code fragment of a Windows Presentation Foundation (WPF)
application shows that the code to handle the users touching/tapping the exit
button is just the very same code that handles a mouse click to the exit button.
public Window1()
{
InitializeComponent();
//add the event handler to handle users click/tap the exit button
button1.Click += new RoutedEventHandler(exitButton_Click);
}
private void exitButton_Click(object sender, RoutedEventArgs e)
{
//close the window to exit the application
this.Close();
}
You may wonder why there is nothing relating to touch in this code. The operating
system synthesizes the tap or the touch on the exit button to the mouse left click
message, so no extra code is needed to handle the tap/touch to the button other
than the usual left mouse click event handler. When users use the mouse and left-
click on the button, exitButton_Click is detected. And the very same exitButton_Click
handler is detected when users touch the button.
