关闭嵌套的模态窗口，而没有“模糊”的声音

Question

I have 3 windows...

1. main : main application,

2. mod-win1 : a modal window opened from main , to edit/create certain objects,

3. mod-win2 : a modal window opened from mod-win1 , as a custom file selector.

mod-win2 is created/opened on a button click on mod-win1 , this is actioned in the layout controller for this window. mod-win1 passes a reference to itself to mod-win2 which mod-win2 uses to call a close method when needed (on cancel/select).

The problem is that whenever the window is closed, it makes a 'blurp' sound - I know, petty, but it's aggravating me! It's the same sound that the locked window behind the modal window makes if you try to click on it, so I'm thinking it's because I'm going back to the layout controller for the locked window in order to close the current one. All my other modal windows close silently, they're not created from within the layout controller of another window!

Can anyone confirm if this would cause this noise?

Also, is there a way to get a window to close itself (from within its layout controller) so I don't have to access the calling object? ...or should I be creating an entirely new object to enclose all the file selector functionality and then calling that object (rather than the mod-win1 layout controller) to close the window?

A Stage can be closed any time by calling its close method. I cannot reproduce your blurping sounds on my Windows 10 machine using JDK1.8.0_92. But check out this example:

package com.isp.stackoverflow;/**

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Modality;
import javafx.stage.Stage;

public class ModalWindowsClosing extends Application
{

  public static void main( String[] args )
  {
    launch( args );
  }

  @Override
  public void start( Stage primaryStage )
  {
    final Button btn = new Button( "click me!" );
    btn.setOnAction( __ ->
    {
      final Stage dialog = new Stage();
      final Button dialogBtn = new Button( "click me again, fool!" );
      dialogBtn.setOnAction( ___ ->
      {
        final Button closeBtn = new Button( "close dialog" );
        closeBtn.setOnAction( ____ -> dialog.close() );
        final Stage innerDialog = new Stage();
        innerDialog.initOwner( dialog );
        innerDialog.initModality( Modality.APPLICATION_MODAL );
        innerDialog.setScene( new Scene( new StackPane( closeBtn ) ) );
        innerDialog.show();
      } );
      dialog.initOwner( primaryStage );
      dialog.initModality( Modality.APPLICATION_MODAL );
      dialog.setScene( new Scene( new StackPane( dialogBtn ) ) );
      dialog.show();
    } );
    primaryStage.setScene( new Scene( new StackPane( btn ) ) );
    primaryStage.show();
  }
}

My guess is, that you have not setup the window owners correctly, but without example code, that is impossible to tell.
