On the teststand below all mouse events are logged, and if there is more than a 1 second delay between them they are separated by a horizontal ruler. Click-related events always have the which property, which allows to get the exact mouse button.

It is not used for click and contextmenu events, because the former happens only on left-click, and the latter β€” only on right-click. So if we want users of all operating systems to feel comfortable, then together with ctrlKey we should check metaKey. Keyboard combinations are good as an addition to the workflow. So that if the visitor has a keyboard β€” it works. For instance, if we have a window of the size x, and the mouse is in the left-upper corner, then clientX and clientY are 0.

And if the mouse is in the center, then clientX and clientY areno matter what place in the document it is, how far the document was scrolled.

They are similar to position:fixed. Document-relative coordinates pageXpageY are counted from the left-upper corner of the document, not the window. You can read more about coordinates in the chapter Coordinates. Double mouse click has a side-effect that may be disturbing in some interfaces: it selects the text. If one presses the left mouse button and, without releasing it, moves the mouse, that also makes the selection, often unwanted. There are multiple ways to prevent the selection, that you can read in the chapter Selection and Range.

In this particular case the most reasonable way is to prevent the browser action on mousedown. It prevents both these selections:.

Please note: the text inside it is still selectable.

Mouse Right Click Example Java

However, the selection should start not on the text itself, but before or after it. If we want to disable selection to protect our page content from copy-pasting, then we can use another event: oncopy.

Surely the user has access to HTML-source of the page, and can take the content from there, but not everyone knows how to do it. Open a sandbox for the task. Open the solution in a sandbox.

We want to make this open-source project available for people all around the world. Tutorial map.No additional dependencies or libraries are required. It is very useful when you want to test desktop or even web application. You can simulated user behavior by using this simple methods. You can simulate typing by this two methods. This one is doing button press and the next one has all letters and special buttons of the keyboard.

Class which shows the usages of this methods. This will help you to automate your tests by key pressing, mouse clicks and moves. Feel free to comment below:. Java robot key press, mouse move and click. Published 2 years ago 6 min read. By John D K. Most popular is by using: java.

Javax Swing JButton. So we have learned how to create JButton, But if we click on the button, nothing happens just because we have not added any action event associated with the JButton.

So now in this tutorial, we are going to learn about event handling for JButton step by step. So this was the brief description of event classes and listeners, and now we will see JButton Click Event step by step in which we will learn about ActionListner interface, ActionPerformed method and addActionListener method. So this was all for tutorial of JButton Click Event. Feel free to ask if you have any queries regarding this JButton Click Event tutorial By commenting on this post.

Java Programming Tutorial - 74 - Mouse Events

Generated when value of text area or text field is changed.Instead the mouse motion events are dispatched to the first ancestors that has enabled mouse motion events. This low-level event is generated by a component object for: Mouse Events a mouse button is pressed a mouse button is released a mouse button is clicked pressed and released the mouse cursor enters the unobscured part of component's geometry the mouse cursor exits the unobscured part of component's geometry Mouse Motion Events the mouse is moved the mouse is dragged A MouseEvent object is passed to every MouseListener or MouseAdapter object which is registered to receive the "interesting" mouse events using the component's addMouseListener method.

MouseAdapter objects implement the MouseListener interface. Each such listener object gets a MouseEvent containing the mouse event. Each such listener object gets a MouseEvent containing the mouse motion event. When a mouse button is clicked, events are generated and sent to the registered MouseListener s. The state of modal keys can be retrieved using InputEvent.

The button mask returned by InputEvent. To get the state of all buttons and modifier keys, use InputEvent. Nevertheless, ordinal numbers starting from 4 may be used as button numbers button ids. Values obtained by the getMaskForButton button method may be used as button masks. In a multi-screen environment mouse drag events are delivered to the Component even if the mouse position is outside the bounds of the GraphicsConfiguration associated with that Component.

However, the reported position for mouse drag events in this case may differ from the actual mouse position: In a multi-screen environment without a virtual device: The reported coordinates for mouse drag events are clipped to fit within the bounds of the GraphicsConfiguration associated with the Component. In a multi-screen environment with a virtual device: The reported coordinates for mouse drag events are clipped to fit within the bounds of the virtual device associated with the Component.

Since: 1. Point getLocationOnScreen Returns the absolute x, y position of the event. Point getPoint Returns the x,y position of the event relative to the source component.

String paramString Returns a parameter string identifying this event. This MouseEvent occurs when a mouse button is pressed and released. This MouseEvent occurs when a mouse button is pushed down.

This MouseEvent occurs when a mouse button is let up. This MouseEvent occurs when the mouse position changes.

This MouseEvent occurs when the mouse cursor enters the unobscured part of component's geometry. This MouseEvent occurs when the mouse cursor exits the unobscured part of component's geometry. This MouseEvent occurs when the mouse position changes while a mouse button is pressed.

This is the only MouseWheelEvent. It occurs when a mouse equipped with a wheel has its wheel rotated. An invocation of the form MouseEvent source, id, when, modifiers, x, y, clickCount, popupTrigger, button behaves in exactly the same way as the invocation MouseEvent source, id, when, modifiers, x, y, xAbs, yAbs, clickCount, popupTrigger, button where xAbs and yAbs defines as source's location on screen plus relative coordinates x and y.Windows only: ClickWhen lets you set up an automated mouse click to run on a window after a user-defined period of time.

Meaning what, exactly? Well, with ClickWhen you can, for example, set up your mouse to pause your iTunes music 30 minutes from now by telling it to click the iTunes pause button. In 30 minutes, ClickWhen will activate iTunes and click the pause button. This may sound like a pretty haphazard idea, but ClickWhen is actually pretty smart.

After the jump, download ClickWhen and read a bit more on how it works. Version: 0. What it does: ClickWhen lets you create automated mouse clicks to be performed after a defined amount of time.

I put ClickWhen together at the request of a reader who needed to automate a mouse click. It's somewhat of a silly application, but with a little imagination, it can be put to good use. Usage: ClickWhen works in three simple steps. Because it's the most readily obvious use of ClickWhen I can think of, I've demonstrated how to use ClickWhen to pause iTunes after 30 minutes below:. Lifehacker photo gallery thumbnails require Javascript; if you're viewing this in an RSS reader, clickhere to see the ClickWhen usage photo gallery in a Javascript-enabled web browser.

Keep in mind that ClickWhen can do the same sort of thing with virtually any application, so you're only limited by your imagination to use it.

I really like the iTunes example because I like to leave music on when I leave a room, but it doesn't really need to stay on. With ClickWhen, I can just set up a timer to turn it off. Or on. Or whatever I want. Like I said above, ClickWhen is fairly smart. You can minimize or resize the application you want to click, and ClickWhen will be sure to restore the window and resize it to the size it was when you set up the mouse click so that you get the click you expected.

Now, Windows does come with the useful Windows Scheduled Tasks utility for automating stuff you want to do every day, so that's not really what this would be best for. However, if you want to quickly set up a very simple action, whether it's launching an application or pausing your digital music, it's a handy little tool.

Known Issues: Currently, ClickWhen will need clean access to your Windows desktop in order to click something on the desktop. That is, if a window is covering your desktop but you set up a desktop click, it will end up just clicking the application floating on top of the desktop this is because you can't "restore" the desktop or put the desktop on top of other applications.

One simple workaround would be the set up the click with an Explorer window that's showing your desktop folder. If there's enough demand, I can work in a fix for this I wanted to push this out as quickly as I could for feedback, so fixing this minor issue is on my backburner. Also, keep in mind when you're setting up mouse clicks that ClickWhen can't account for dynamic window content.

Going back to the iTunes example: if you were to set up a double-click on an actual song to play it, it would only work if the library contents in the main iTunes screen hadn't scrolled to new territory.

ClickWhen is portable, so you can grab just the. It's also open source, so you can check out the source code here.

ClickWhen is written in Autohotkey. Bug reports and feature requests: Aside from the quirks mentioned above, ClickWhen should generally work exactly as you expect it to. However, that doesn't mean it's bug-free. If you find a problem or you've got a suggestion for how I could improve ClickWhen, let's hear it in the comments.Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available.

Mouse events notify when the user uses the mouse or similar input device to interact with a component. Mouse events occur when the cursor enters or exits a component's onscreen area and when the user presses or releases one of the mouse buttons.

Tracking the cursor's motion involves significantly more system overhead than tracking other mouse events. To track mouse wheel events, you can register a mouse-wheel listener. If an application requires the detection of both mouse events and mouse-motion events, use the MouseInputAdapter class. The following example shows a mouse listener.

At the top of the window is a blank area implemented by a class named BlankArea. The mouse listener listens for events both on the BlankArea and on its container, an instance of MouseEventDemo. Each time a mouse event occurs, a descriptive message is displayed under the blank area. By moving the cursor on top of the blank area and occasionally pressing mouse buttons, you can fire mouse events. You can find the demo's code in MouseEventDemo. Here is the demo's mouse event handling code:.

The MouseListener Interface. All its methods have an empty body. So a developer can define methods for events specific to the application. The MouseInfo class provides methods to obtain information about the mouse pointer location at any time while an application runs.

The mouse clicks are used to draw on the panel area using drawline instructions. Implementing the MouseListener interface requires that we implement all the methods called for by the interface. We only use MouseClicked in this example, however, so it's the only one that has code in its code block. This program lets you draw by clicking the mouse at various places in the MousePanel's drawing area, drawing a line from the prior click location or from top left for the first click to the location of the current click.

Here's a little challenge for you: Change the program so that it doesn't draw a line from upper left on the first click, but instead draws a dot in the location of the first click. Later clicks will then draw lines from the prior click's location. Hint: If you set the initial oldX and oldY values to a value that isn't in the visible MousePanel area, you can tell if there haven't been any prior clicks.
