JavaFX default focused button in Alert Dialog

Question

Since jdk 8u40, I\'m using the new javafx.scene.control.Alert API to display a confirmation dialog. In the example below, \"Yes\" button is focused by default inste

Answer 1

A simple function thanks to crusam:

private static Alert setDefaultButton ( Alert alert, ButtonType defBtn ) {
   DialogPane pane = alert.getDialogPane();
   for ( ButtonType t : alert.getButtonTypes() )
      ( (Button) pane.lookupButton(t) ).setDefaultButton( t == defBtn );
   return alert;
}

Usage:

final Alert alert = new Alert( 
         AlertType.CONFIRMATION, "You sure?", ButtonType.YES, ButtonType.NO );
if ( setDefaultButton( alert, ButtonType.NO ).showAndWait()
         .orElse( ButtonType.NO ) == ButtonType.YES ) {
   // User selected the non-default yes button
}
