I just want to make javaFX Confirmation dialog without cancel button.
When i just made dialog without cancel button, "X" button to close the dialog does not work.
How can i make without "Cancel" button?
Alert alert = new Alert(AlertType.CONFIRMATION);
alert.setTitle("Confirmation Dialog with Custom Actions");
alert.setHeaderText("Look, a Confirmation Dialog with Custom Actions");
alert.setContentText("Choose your option.");
ButtonType buttonTypeOne = new ButtonType("One");
ButtonType buttonTypeTwo = new ButtonType("Two");
ButtonType buttonTypeThree = new ButtonType("Three");
ButtonType buttonTypeCancel = new ButtonType("Cancel", ButtonData.CANCEL_CLOSE);
alert.getButtonTypes().setAll(buttonTypeOne, buttonTypeTwo, buttonTypeThree, buttonTypeCancel);
Optional<ButtonType> result = alert.showAndWait();
if (result.get() == buttonTypeOne){
// ... user chose "One"
} else if (result.get() == buttonTypeTwo) {
// ... user chose "Two"
} else if (result.get() == buttonTypeThree) {
// ... user chose "Three"
} else {
// ... user chose CANCEL or closed the dialog
}
In this code i want to remove
ButtonType buttonTypeCancel = new ButtonType("Cancel", ButtonData.CANCEL_CLOSE);
to make user can choose one of "One, Two, Three" without cancel button but the "X" button to work well.
I just tried like this.
Alert alert = new Alert(AlertType.CONFIRMATION);
alert.setTitle("Confirmation Dialog with Custom Actions");
alert.setHeaderText("Look, a Confirmation Dialog with Custom Actions");
alert.setContentText("Choose your option.");
ButtonType buttonTypeOne = new ButtonType("One");
ButtonType buttonTypeTwo = new ButtonType("Two");
ButtonType buttonTypeThree = new ButtonType("Three");
alert.getButtonTypes().setAll(buttonTypeOne, buttonTypeTwo, buttonTypeThree);
Optional<ButtonType> result = alert.showAndWait();
if (result.get() == buttonTypeOne){
// ... user chose "One"
} else if (result.get() == buttonTypeTwo) {
// ... user chose "Two"
} else if (result.get() == buttonTypeThree) {
// ... user chose "Three"
} else {
// ... user chose CANCEL or closed the dialog
}
But when i made like this, the "X" button does not work. How can i handle this?

I just made the Button invisible.
Alert alert = new Alert(AlertType.CONFIRMATION);
alert.setTitle("Confirmation Dialog with Custom Actions");
alert.setHeaderText(null);
alert.setContentText("Choose your option.");
ButtonType buttonTypeOne = new ButtonType("One");
ButtonType buttonTypeTwo = new ButtonType("Two");
ButtonType buttonTypeThree = new ButtonType("Three");
ButtonType buttonTypeCancel = new ButtonType("Cancel", ButtonData.CANCEL_CLOSE);
alert.getButtonTypes().setAll(buttonTypeOne, buttonTypeTwo, buttonTypeThree, buttonTypeCancel);
alert.getDialogPane().lookupButton(buttonTypeCancel).setVisible(false);
Optional<ButtonType> result = alert.showAndWait();
if (result.get() == buttonTypeOne){
// ... user chose "One"
} else if (result.get() == buttonTypeTwo) {
// ... user chose "Two"
} else if (result.get() == buttonTypeThree) {
// ... user chose "Three"
} else {
// ... user chose CANCEL or closed the dialog
}
