JavaFX: Dialog with custom actions

Using ButtonType, you can set custom actions to a Dialog box. ButtonType class is used as part of the JavaFX Dialog API (more specifically, the DialogPane API) to specify which buttons should be shown to users in the dialogs.

 

 

In the above example, three button types (Approve, Reject, remindMeLater) added to the Dialog box.

 

Example code snippet

ButtonType approveButtonType = new ButtonType("Approve");

ButtonType rejectButtonType = new ButtonType("Reject");

ButtonType remindMeLaterButtonType = new ButtonType("remindMeLater");

 

dialog.getButtonTypes().setAll(approveButtonType, rejectButtonType, remindMeLaterButtonType);
