Move user mouse to a certain point

I would like to know how can I create a mouse move after pressing a button?
I am a fish in coding starting with a simple project and would love to create a step by step clicking process where the mouse will be scrolling and pointing in a certain point, img, or maybe to a class of my project?

Currently, there is no way to force a mouse movement via Javascript mainly due to its security implications.
In your case, you can use focus to guide the user to the specific portion of the page that you want.

You cannot move the mouse in JavaScript for the moment. What you can do however is scrolling the page so that a elements goes under the mouse cursor.
My idea is to move the element you want with JavaScript under the mouse cursor. When the user clicks your button, you can, in the event handler capture the mouse coordinates and use those to place any element exactly under the mouse cursor.
The result of the mouse cursor is above this element can be achieved that way.

try to Create COM, then client will ask to accept some installation.

How can I do a "mouse out" effect in Java?

I'm trying to mouse over a JButton (javax.swing.JButton) and set the border color, Now I can get this to work I with a mouse move event on the button, I just need to mouse out and I can't seem to find a way to get a mouse out effect to work. Any ideas or methods that could help? Note: MouseExited does not work. At least in my instance.

What about a "mouse over" on the buttons parent Component? Set a flag if the mouse is over the button and if it is over the parent (surrounding) panel and the flag is set, you have something like "mouse out".

Using the mouseExisted method is the way to achieve this effect. If you are having trouble with it, then it is a problem in your code, but you are going down the right path.

JAVA click with mouse, move with keyboard

I wanted to select an object inside the JFrame and move it with the keyboard arrow keys. I did the keyboard thing, whenever I pressed the arrow keys it moves accordingly to the direction. What I want is to move multiple objects. I tried to put an multiple objects and they did moved at the same time xD
tldr; is there a way where you can click on just one object using the mouse and control it with keyboard arrow keys?

Eventhough question not clear enough, moving single or multiple objects is not a problem. You need to use KeyEvent Listener for the object you want to listen and move the components based on KeyEvent.

Java popup trigger in Linux

I have an application in which you can do a right mouse button press and drag (as well as a left press and drag for different operations). However, when running this on linux, it seems that popup menus are triggered by a mousePressed and not a mouseReleased. This is resulting in every time I press the right mouse button to perform a drag, the popup menus are triggered (unlike windows, where it is mouseReleased).
Any thoughts on how to work around this?
thanks.
EDIT: Posting code
Code for popup menu
// this is called from mousePressed and mouseReleased
if (e.isPopupTrigger() && !e.isConsumed()) {
// show the popup menu
}
This code is what is called on the right mouse press/drag (this is 3rd party code, but it is open source so I can change as needed)
// this is called on all mouse events
if (buttonAction.mouseButton != 0)
{
// handle the event
}

Yes, use isPopupTrigger(), as shown here.
Addendum:
it appears isPopupTrigger is triggered on mousePressed in linux.
Yes, it's the same on Mac OS X. You have to call isPopupTrigger() from both mousePressed() and mouseReleased(). There's a related example in GraphPanel.

MouseEvent.isPopupTrigger(). Returns whether or not this mouse event is the popup menu trigger event for the platform.
edit - : You need to make the check in both mousePressed for linux, and mouseReleased for windows.

I think the correct procedure in your case should be to unify where and when to show the popup. As a drag event, if exist, follows a press event you should avoid writting logic for showing the popup in the press event (and then also write logic in the press event for showing the popup). Some users feel good navigating the popup while holding the popup button, and some other users just don't care or don't know. But in your case, you won't be able to navigate the popup menu while dragging without adding extra code.
My way would we to manage the logic to always show the popup on the release event. Entering a release event after a drag should be enough information to know that the popup shouldn't be visible. And of course, always if you can change and modify the source.

Can we tell if the mouse actually clicked on a checkbox in Java?

Here is the scenario. I have an swing applet with tons of checkboxes. some of them are disabled/unchecked when checking another. Each ItemStateChange() event executes a method to parse the entire form for changes. Is there a way to tell if an ItemStateChange() event was triggered due to a mouse click or from a setSelected() call?
The ItemStateChange() for each checkbox has the standard parameter java.awt.event.ItemEvent evt
I'd like to only call the processOrder() method once when a box is clicked. Right now it fires for each change thats made, regardless of whether the change happened from setSelected(). Sometimes there are 10+ parseForm(); calls from a single click.

You can't tell whether the source of the event is a mouse click or a setSelected call from the ItemEvent.
It sounds like you have a loop in your check box logic. You might want to add a controller that handles the events and sets each checkbox yet ignores events that occur due to calling setSelected on other check boxes.

Is there a way to tell if an ItemStateChange() event was triggered due to a mouse click or from a setSelected() call?
If your application manually invokes the setSelected() method then you can use code like:
checkBox.removeItemListener(...);
checkBox.setSelected(...);
checkBox.addItemListener(...);

If you are able to change to use a MouseListener instead of an ItemListener and respond to the mouseClicked() event you will only receive the events for the checkbox selected by the user.
