Is there any way to block the control key in java. I have looked and looked but I have not found any way to do it thanks in advance
There is no way to block CTRL+ALT+DELETE. In any way, shape or form. It is an absolute guarantee against hacking.

How to disable Button when TextField is empty?
(3 answers)
Closed 3 years ago.
I want to disable the button when the text fields are empty.
I have created two fields with the onKeyReleased property
Sorry i sent it unintentionally.
Something like btn.disableProperty().bind(field.textProperty().isEmpty()) should work.
In the future please add a compilable skeleton and what you have tried so far to your question. That makes it way easier to help.

Getting active window information in Java
(3 answers)
Closed 4 years ago.
I'm trying to get the state of a window on Windows. I have to check if the window of word is active or inactive. I don't find any answer to this problem in Google.
Does anyone knows how to do this or if this is possible at all?
Window activeWindow = javax.swing.FocusManager.getCurrentManager().getActiveWindow();
The code above returns always NULL.
Thank you for your answers.
Regards
Roman
Try to use frame.hasFocus() or frame.isFocusOwner()
