Java mouse coordinates offset

JAVA MOUSE COORDINATES OFFSET CODE

You would then be in a position to better ascertain the location of the image and convert the mouse point values you require, for example. Instead, you could create a custom component and render the image the way you want. At the time of mouse click, variable x will get X coordinate an y will get Y coordinate or mouse click location. Here Mouse Adapter class used to implement mouse click event. We can capture any mouse clicked location or position on a java applet or frame. While you could create your own delegate, you would end up needing to create one for each supported platform and.I'm too lazy. Get X, Y Coordinate at Mouse Clicked Location in Java Applet or Frame.

How can I modify above code to get coordinates relative to image?īasically, it would be very hard to achieve this using a JLabel as the actual position of the image is determined by the JLabel's look and feel delegate. So here's the problem: the JPanel is larger than the image and the JScrollPane is taking up 100% of the JPanel (which looks nice, I'm happy about that) but the mousePressed event is giving me the coordinates relative to the JScrollPane/JPanel, not the image so the x coordinate is offset (even though the mouseListener was add to the JLabel containing the ImageIcon). ScreenLabel.addMouseListener(new MouseAdapter() //I override only one method for presentation Removing all the stuff about the offset, you can easily get the X, Y coordinates of the click relative to the browser. ScreenScroll.getViewport().setBackground(Color.white) See Java Language Changes for a summary of updated language features in Java SE 9 and subsequent releases. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available. JScrollPane screenScroll = new JScrollPane(screenLabel) The Java Tutorials have been written for JDK 8. final JLabel screenLabel = new JLabel(new ImageIcon(image)) The JScrollPane, screenScroll, is contained in a JPanel with a BorderLayout. Tip: To get the vertical coordinate (according to the client area) of the mouse pointer, use the clientY property. I want to get the mouse coordinates of a mouse click relative to an image which is within a JSrollPane. The clientX property returns the horizontal coordinate (according to the client area) of the mouse pointer when a mouse event was triggered. The MouseListener interface is found in package. You can simulated user behavior by using this simple methods.I am building a desktop application in Java. The Java MouseListener is notified whenever you change the state of mouse. It is very useful when you want to test desktop or even web application. No additional dependencies or libraries are required. Java has several ways to simulate user inputs.
