javafx close all windows on application close

Then you can exist the application explicitly. If you exit the application, it exists there are no windows, nothing. In other words, by default, there is nothing you need to do. You did not show anything like that, anyway. If you prevented it and don't realize how, nothing could help except getting to understand each like you write.

If the window is shown via Window.ShowDialog, you just close it, and, when it is modal, you cannot touch any other window, not main, not any one else.Īnd then, in contrast to all the above, by default, closing the main window not only closes all the window, it also exits the application - unless you prevent it. You can prevent is and hide it instead, to show later this is one of the most popular technique. Now, the default behavior is this: if you close a non-main window shown via Window.Show, you just close it and effectively lose it. The recommended way of doing custom dialogs are using the same very Window class as a base class. I have no idea of your CustomDialog type you should have shown it. So, even the same Window instance can be shown in a modal or not modal way. The second case simulates modal behavior. All other windows can be shown via Window.Show or Window.ShowDialog. What window instance is main is defined by current Application object, this is the window which was passed as a parameter to Application.Run. Also, there is an optional ownership relationship, but it's irrelevant to the issue. There is main window and other windows, this is all which makes the difference. For windows, there is no such relationship as child-parent.
