Trapping Ctrl + C

Posted by Kishori Sharan on September 15, 2000 at 2:14 PM

If in a GUI you want to trap Ctrl + C then you need to use registerKeyBoardAction ( ) method of JComponent along with an object of KeyStroke. YOu need to pass an object of a class which implements ActionLisner interface. When that key is pressed actionPerformed ( ActionEvent e ) method will be automatically called and you can do your processing. YOu have also got options when this key press should be trapped e.g. when focus is in that component ot when focus is anywhere or when focus is in the parent of the component. This is useful when you want to trap Ctrl + C in whole window i.e. whenever user presses Ctrl + C you may want to close the window. If you need code let me know I will send you an example.
