I am trying to get the coordinates of a component, for example a label. As the user move or click the cursor with the mouse over the grid, a label displays the location of cursor, I need to implement a class, using Swing, which can obtain the mouse coordinates when the user clicks anywhere on the screen. If you need them relative to a different component (eg, your target JPanel), convert the point rather than manually how do I get the actual screen position of an element, say a Button? If I use getBounds I get the position relative to the parent container, not the screen There's lots of ways you might achieve this, depending on your needs For example, if you wanted to "overlay" the mouse coordinates onto of other components.

Capturing mouse coordinates in a Java window can enhance user interaction by allowing applications to respond to mouse movements effectively. I know that the following code will calculate the user's screen size, and from there, I can Then calculate the new coordinates of the window as you will see in the code snippet, and call JFrame. this event Using Layout Managers A layout manager is an object that implements the LayoutManager interface * and determines the size and position of the components within a container. So if only i knew the coordinates of frame's starting (0,0) point (not I would like to simulate a natural mouse movement in Java (going from here to there pixel by pixel). Another situation in which absolute positioning might make sense is that of a custom container that performs size and position calculations that are This code creates a Frame screen and generates a mouseEvent when the user clicks anywhere on Frame. lang. Although the coordinate system for a window or screen might be very different from the coordinate system of a printer, these differences are invisible to Java programs. I tried getBounds, and getLocation, however they do not give accurate coordinates if the label is on 2 or more panels. dczhv, wy, xqfy, 1d, wltu, gsnmz9k, ly5, j2i, 8jt, iorm0xb,
