I had created a JOptionPane of type showInputDialog. When it opens it, it shows me two buttons: OK and Cancel. I would like to handle the action when I push on Cancel button, but I don't know how to reach it. How can I get it?
For example:
int n = JOptionPane.showConfirmDialog(
frame, "Would you like green eggs and ham?",
"An Inane Question",
JOptionPane.YES_NO_OPTION);
if (n == JOptionPane.YES_OPTION) {
} else if (n == JOptionPane.NO_OPTION) {
} else {
}
Alternatively with showOptionDialog:
Object[] options = {"Yes, please", "No way!"};
int n = JOptionPane.showOptionDialog(frame,
"Would you like green eggs and ham?",
"A Silly Question",
JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE,
null,
options,
options[0]);
if (n == JOptionPane.YES_OPTION) {
} else if (n == JOptionPane.NO_OPTION) {
} else {
}
See How to Make Dialogs for more details.
EDIT: showInputDialog
String response = JOptionPane.showInputDialog(owner, "Input:", "");
if ((response != null) && (response.length() > 0)) {
}
