I'm stuck with the following.
I'm programming a game and I need to get the mouse pointer location inside the JFrame, I don't need to get the pointer location on the screen, but just in the JFrame. When you use the MouseClick event you could get the position in the frame while the mouse button is pressed, but I want to get it's location when no button is pressed.
I hope you understood my question.
Sounds like you need a MouseMotionListener.
The MouseEvent contains the current mouse position.
void mouseMoved(MouseEvent e)
Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.

I want to get mouse event while mouse click is held down but is not moving.
mouseDragged only works while the mouse is moving, but how can I get the event while mouse is not moving.
I'm using java.awt.event.MouseListener
Thank you.
There is a full javadoc for AWT (also for a lot of other api): https://docs.oracle.com/javase/7/docs/api/java/awt/event/MouseListener.html
void mousePressed(MouseEvent e)
Invoked when a mouse button has been pressed on a component.
void mouseReleased(MouseEvent e)
Invoked when a mouse button has been released on a component.
The mouse doesn't detect any events while mouse click is held down and the mouse is in place
I'm creating the following UI in Java.
When a user hovers their mouse over a particular area on the screen, a popup appears that contains a bunch of buttons and controls.
PopupFactory factory = PopupFactory.getSharedInstance();
_hoverPanel = factory.getPopup( parent, panel, x, y );
_hoverPanel.show();
I want this panel to remain visible on the screen while the user interacts with the panel's components, but as soon as the users mouse exists the popup bounds I want the popup to hide.
I tried adding a mouselistener to the panel inside the popup but I noticed that mouseEntered only fire when I enter the panel (and not when I enter components found inside the panel) and mouseExited only fires when I exit the panel.
The problem here is that I can make the popup appear, but as soon as I move my mouse inside the panel, and then over top of a component inside the panel, mouseExited fires for the panel, and the popup hides :(
I can also move my mouse quickly inside the panel over top of a component, and mouseEntered never fires for the panel :(
How can I detect when the mouse goes inside and outside my popup panel?
I had a similar problem (catching all mouse events while the mouse hovers over my dialog) and I solved it by wrapping the root pane of the dialog in a JLayer (javax.swing.JLayer) as shown in http://docs.oracle.com/javase/tutorial/uiswing/misc/jlayer.html#events
Hi and thanks in advance!
I've been working on a game project and no I'm looking into making a basic GUI. To put it short this is what I'm trying to achieve:
The primary component is a J(Scroll)panel that houses moving in-game objects. I want the players to be able to hover the mouse over an object and get some kind of information popup that is tied to the location of the object hovered over. Secondly I want the user to be able to click on an object with the left mouse button in order to "select" the object and also to be able click with the right mouse button to open a popup menu next to the object.
You should add a mouse listener to your panel. Like this:
panel.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent me) {
System.out.println(me);
}
});
I use a mouse move listener to handle mouse moves on a canvas in SWT.
But I'd like to have two behaviours, one when the mouse is moving into the canvas area and another one when the mouse is quiting the area.
In fact what I really like to do is to change the cursor icon when the mouse is in the area and restore it when it is out. But I can only capture events when the mouse is in the area.
Is there a specific listener to handle the Mouse Out event on a Canvas?
Thank you.
You are looking for a MouseTrackListener, it has methods for entering, exiting and hovering an element. See http://help.eclipse.org/indigo/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/events/MouseTrackListener.html
This is what you're looking for:
public void mouseExited(MouseEvent e) {
saySomething("Mouse exited", e);
}
Follow this link:
Oracle MouseListeners
In some situations I need to place a JFrame right where the mouse cursor is located. Do I really need a mouse listener to track mouse move events, or I can just read current mouse position somehow?
this could help:
MouseInfo.getPointerInfo().getLocation()
