How to Attach Modal Dialogue to Main Window in JavaFX?

Examples of Attached Modal Dialogues:
Is there any way to bring this to JavaFX?

Couldn't find support for attached dialogs out of the JavaFX box... So, how I would do it...
The dialog part: there's this, no way I'm beating it example gist
And a tweak to the CSS file - the .modal-dialog styleClass:
-fx-position: fixed
-fx-top: 0

SWT disable window causes lose focus

I'm making custom dialogs that I want to pop up and disable the main shell behind it so that it cannot be clicked while the dialog is active.
My initial plan was something like as follows:
shell.setEnabled(false);
doDialogStuff();
shell.setEnabled(true);
this worked but as I close the dialog, it loses focus of the shell that was open before the dialog. I managed to sort of fix it by adding
shell.setFocus();
after the last line but this is messy and causes the screen to flicker as the window loses and then gains focus in a split second, also, it sometimes doesn't regain focus and I can't understand why :/
Is there a better way to disable the background window without it losing focus.
Thanks in advance SO peeps

You should create a custom dialog based on this tutorial.
This way you just have to set the modality of the dialog to whatever you need exactly and the dialog will take care of the rest for you.
This should be helpful as well (Javadoc of Shell):
The modality of an instance may be specified using style bits. The modality style bits are used to determine whether input is blocked for other shells on the display. The PRIMARY_MODAL style allows an instance to block input to its parent. The APPLICATION_MODAL style allows an instance to block input to every other shell in the display. The SYSTEM_MODAL style allows an instance to block input to all shells, including shells belonging to different applications.

The proper thing to do is create the dialog as a modal window. When you create the dialog's shell you should do something like
dialogShell = new Shell(mainShell, PRIMARY_MODAL | DIALOG_TRIM);

How to make a java swing popup window with combo box and 2 buttons?

I need to make a popup box with with a combo box and a couple of buttons. Please could someone advice on the best way to achieve this? I've had a look around and all I can find is alert boxes. Is this possible or will I need to create a whole new frame?

You can use the JOptionPane to achieve this. Please refer to the link below which explains this with sample code:
http://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html#input

JOptionPane.showInputDialog may be good enough if you are willing to leave how exactly the options are presented up to the UI.

I need to make a popup box with with a combo box and a couple of buttons
1) don't use another JFrame as popup window, use JFrame with JOptionPane/JDialog/JWindow these container are same as JFrame, but can take parent and owner
2) don't forget to setParent
3) depends if you needed decorated window then use JDialog, don't forget look for setModal() or ModalityTypes, if undecorated then use JWindow
4) don't create lots of JOptionPane/JDialog/JWindow on fly, becasue there Object are still in JVM memory, create this Container once and re-use that (by removing child) for another Action

Resizing JPopupMenu and avoiding a "flicker" issue

I am trying to implement a search results popup list similar to the style found here:
http://www.inquisitorx.com/
(I'm not trying to implement a Google search, I'm just using this as a rough example of the style I'm working on.)
In any event, I am implementing this by using a JList contained within a JPopupMenu which is popped up underneath a JTextField.
When a user enters search terms, the list changes to reflect different matching results. I then call pack on the JPopupMenu to resize it.
This works, however, it creates a slight flicker effect since it is actually hiding the popup and showing a popup. (See the private method getPopup in JPopupMenu where it explicitly does this.)
Is there any way to just get it to just resize itself (aside from using a JWindow)?

to me work :
popup.pack();
popup.validate();
this work in linux with java version "1.6.0_34". I don't know is that work on windows.

The setSize() method didn't work in my case. The popup.pack() approach did work, but also resulted in a flicker. The best solution that I have found was the one found here. In short:
Window window = SwingUtilities.getWindowAncestor(popupMenu);
window.pack();
window.validate();

Have you tried setSize()? It looks like that gets handled in JComponent and might avoid the repaint issues.
I think the issue that getPopup is addressing is what to do when the dimensions of the popup will not fit within the window. When that happens, it drops back from a lightweight component to a heavyweight and that definitely requires a hide and show. So, I think if you can guarantee your popup won't extend beyond the window the setSize might do the trick.

How do I get "Goodbye Window" to show up in Java?

I have a Java network application and this is what I want to do:
After user logs out, his interface window closes.
Now, I want for another window to show up that will say something like: "Thank you for using our application".
This final window should be borderless and without any available option, more like a plain picture (jpeg? why not?). By clicking on it, user will be sure to close this final window.
I googled and couldn't fin anything on this matter, it's hard to phrase the question.
I hope someone helps me...

https://docs.oracle.com/javase/1.5.0/docs/api/javax/swing/JWindow.html
A JWindow is a borderless, undecorated JFrame (no titlebar or buttons).
This should be what you need.

This should help:

You're interested in the windowClosing and windowClosed events

You have various possibilities, depending on when you want this dialog to display :
if you want it to display juste before the app closes, use addShutdownHook
if you want it to display when the last window closes, use addWindowListener
You can then use a JWindow with your image inside, and use addMouseListener to wait for the user to click on it.
