Key strokes from mouse interaction in a GUI

in General Discussion • Other • 2 years ago

Is it possible to have your mouse hover over a box, and when it is in said box a key is pressed/held? When you remove your cursor from the box, the key is released.

ie.

1. move mouse to be over top of box, the key 'a' is pressed (you could see it in notepad or something)

3. retract mouse from box, key press stops

I've been mostly using the default libraries for my project, but the toxic lib one is nice as well. If any one has any suggestions that would be awesome!

Look at the Java Robot class. Search the forums for examples.

So another question then. Do I have to change over to eclipse to use the Robot class? How do Implement it.

All the examples I can find deal with the user pressing a button then the code recognizes that the button was pressed. That is not what I want. I would like to mouse over a box and that box start typing the letter 'A'. or hold it down. This is not a real life keystrok like it is when I am typing a response. It is a simulated keystroke. But how is this done?

No, you can use any Java library or built-in class within Processing.
And if you look at the page I link to, you can find keyPress() which is probably what you want. Honestly, I never tried it, but I suppose it sends the key press to the application having the focus on your system.

Java isn't the best tool for such application. If you are on Windows, I would recommend to use AutoHotkey or AutoIt for such automation task, they are much more flexible and integrated to the system.
