This question already has an answer here: How to simulate keyboard presses in java? 1 answer What the java program should do is it should trigger keyboard press on some condition without a person pressing a keyboard key. So any program running in windows and in focus which requires keyboard input will get the input without a person actually pressing the keyboard. I found these related questions here : question 1 , question 2 I was wondering if there is any method to do this in Java. Use the Robot class. Code snippet: import java.awt.Robot; import java.awt.KeyEvent; Robot r = new Robot(); int

How do I read pixels from a PNG file?

I know how to capture a screenshot by using Robot, Windowtester or FEST. I also know how to read a pixel from the screen by using robot. int x = 10; int y = 10; Color px = getPixelColor(int x, int y); However, I don't know how to read a pixel from an image that is already captured. I'm planning to compare a current image, with an image from file. Lets say both are PNG. Are there any frameworks that I can use to compare images pixel by pixel? hughes Is this in Java? If so, you can use ImageIO.read( "yourImage.png" ) to get a BufferedImage . That will have a getData() method which will give you

Does anyone know of a Python class similar to Java Robot ? Specifically I would like to perform a screen grab in Ubuntu, and eventually track mouse clicks and keyboard presses (although that's a slightly different question). If you have GTK, then you can use the gtk.gdk.Display class to do most of the work. It controls the keyboard/mouse pointer grabs a set of gtk.gdk.Screen objects.

How to move a mouse smoothly throughout the screen by using java?

问题 There is a mouseMove()method that makes the pointer jump to that location. I want to be able to make the mouse move smoothly throughout the screen. I need to write a method named mouseGLide() which takes a start x, start y, end x, end y, the total time the gliding should take, and the number of steps to make during the glide. It should animate the mouse pointer by moving from (start x, start y) to (end x, start y) in n steps. The total glide should take t milliseconds. I don't know how to get

Programmatically clicking a GUI button in Java Swing

由 六眼飞鱼酱① 提交于 2019-11-27 01:12:41
问题 How would I programmatically click a Swing JButton in a way that would register all the relevant action/mouse events and be visible to the user (i.e. they'd see the button being pressed as if they actually clicked it)? The button is in the same application I'm running; I'm not trying to control a button in another application. I suppose I could directly inject events into the queue, but I'd prefer to avoid that approach if possible, and doing it that way wouldn't show a visible click. I see
