I want to generate mouse click events for a Java application. I am aware that there is java.awt.Robot, which would allow me to do this. However, I would like that the generated mouse events do not actually affect the "cursor". That is, I would like to be able to minimize the window of the Java program and do other things with the mouse cursor, while mouse events are still generated for that program. How could I do that?
Edit: Furthermore, I cannot be assumed that there is a number of buttons that I need to interact with. Rather I'd like to generate mouse click events as if I had clicked at a certain position within the window.

I want to simulate basic input for a swing application. The whole thing runs headless and doesn't even have a JFrame. I just render all components from the JPanel using the draw() method on a Image (If you want to know why: The Image gets rendered on minecraft maps where users then should be able to interact). I want to execute click or scroll actions on the panel like it would come from regular user.
I know that I can simulate a Button click using doClick() but this doesn't work for components like checkboxes. I also tried using dispatchEvent() but that didn't fire the animations or on some components even threw a HeadlessException.
I need your help with my application.
I'm writing a program that displays big images in tiles, using the SWT MapWidget (http://mappanel.sourceforge.net/swt/).
The user has the ability to place markers on the map, when he pressed the mouse for a couple seconds. Additionally, I also need a little ZoomBox next to the cursor that shows the area around the cursor, so that the user has better precision when placing a marker. This ZoomBox is to be displayed while the user keeps the mouse pressed. Placing the markers ia already working fine.
I have problems with implementing the ZoomBox, specifically displaying it. I found a post that does just what I need (Zoom box for area around mouse location on screen). The problem is, this post is for Swing and not for SWT.
I have already built a SWT_AWT-Bridge, so I have the ZoomPanel already in my shell. What I need is the functionality of displaying it on top of the MapWidget, while the user keeps the mouse pressed.
I figured, I need to use a StackLayout, but I don't know how.
EDIT
To clarify, my question is, how can I display the composite containing my ZoomBox on top of my image, while the user keeps the mouse pressed?
How would I let a user draw lines on a canvas in JavaFX? I define a line as where the mouse went over between a click and a release. I'm thinking of using a mouse event handler and a Path, but I was wondering if there's anything built in that I could use. Thanks!
I have a small program that allows the user to draw lines from a tree on the left to a tree on tree on the right.
If the user clicks on an item in the left tree, a line is drawn and the endpoint is bound to the mouse position (a custom handler is registered to monitor for mouse movement and updates two properties that allow you to bind to it). This works great.
Is there a way for Java to listen to another program for mouse clicks?
If so, is there a way to listen for mouse clicks on text inputs on other programs?
I'm making an on screen keyboard for a project I'm working on. It will automatically be displayed when the user selects any text input on the screen. When the text input is unfocused, the keyboard would disappear.
Strictly speaking, in Java there is no way to detect Mouse or Keyboard events when your application is not in focus. This is a security mechanism that is built into Java.
An application cannot listen for these events unless it has root (admin) privileges anyway.
If i read correctly, the mouse and keyboard listeners are intended to capture movement within an application. what I want to do is capture movement system wide.
Mouse movement/clicks and button presses.
Ideally i would like a manner of capturing this movement and being able to replay it by passing appropriate commands to the robot class. Does this seem reasonable, or am i going about this all wrong?
It is possible if you create transparent full screen window and capture events on it.
To replay the events use class java.awt.Robot.
