Swing Mouse Event Propagation

Hello,
I'm developing my first Swing application.
One of the components is a thumbnail image panel (ext. JPanel) containing several other components (mostly ext. JLabel). I have the image panel receiving mouse events so as to allow the user to see when the image panel is 'in focus' (rollover effect basically) and to allow the image panel to be selected by clicking.
I added a tooltip to one of the contained labels, and it now 'consumes' my mouse enter/exit event so that now it is as if the label is not part of it's container. This is not what I want.
Is there not some simple way to allow mouse events to be listened for by a child component but yet to 'fall through' to a listener in the parent component?
Any insight into this little problem would be most appreciated.
Thanks.

You can listen to all MouseEvents generated:
Toolkit.getDefaultToolkit().addAWTEventListener( new AWTEventListener()
public void eventDispatched(AWTEvent e)
System.out.println(e);
}, AWTEvent.MOUSE_MOTION_EVENT_MASK + AWTEvent.MOUSE_EVENT_MASK);You would then need to determine if the source component is a descendent of your main panel.

Multiple JPanels on top of each all receiving mouse events

I have multiple JPanels that are painted on top of each other. Each one has mouse listeners that listen for mouse enters, exits, etc. However, it appears that Swing is only propagating the mouse events for the most visible panel (the one that is on top of all of the others). Is there a way to configure Swing in such a way that all JPanels on the screen will get the mouse events, even if they aren't entirely visible on the screen?
Thanks,

Hi,
You can implement mouse listener for panel and you can identify buttons in the panel with the mouse event of panel using MouseEvent.getComponentAt(MouseEvent.getPoint()) instanceof JButton or not.
I hope this will help,

How to catch the mouse event from the JTable cell of the DefaultCellEditor

Hi, my problem is:
I have a JTable with the cells of DefaultCellEditor(JComboBox) and added the mouse listener to JTable. I can catch the mouse event from any editor cell when this cell didn't be focused. However, when I click the editor to select one JComboBox element, all the mouse events were intercepted by the editor.
So, how can I catch the mouse event in this case? In other word, even if I do the operation over the editor, I also need to catch the cursor position.
Any idea will be highly appreciated!
Thanks in advance!

Hi, bbritta,
Thanks very much for your help. Really, your code could run well, but my case is to catch the JComboBox event. So, when I change the JTextField as JComboBox, it still fail to catch the event. The following is my code. Could you give me any other suggestion?
Also, any one has a good idea for my problem? I look forward to the right solution to this problem.
Thanks.

Mobile IconItemRenderer - prevent event propagation

Hello,
I don't want anything to happen when an element is clicked or touched in a mobile itemRenderer extending IconItemRenderer.
Isteand of overriding the drawBackground method and not listening for the change event, is there anyway of doing this faster, like preventing the event from propagating?
Thank you.

1. commitProperties seems fine
2. I assume it would be faster since you avoid unnecessary drawBackground calls. You might want to test to make sure.
3. Correct, if you can't click on something it won't be able to fire a mouseDown event
4. The mouseDown listener is added to the renderer in List.dataGroup_rendererAddHandler. You could tweak it there, but that would require a subclass of List. I typically find it easier to do from within the renderer via one of the two approaches I mentioned above especially when that changes based on the data in the renderer.
5. The Flex SDK currently deals exclusively with mouse events. See the "Mouse vs. Touch Events" section of this spec for more information: http://opensource.adobe.com/wiki/display/flexsdk/Mobile+List%2C+Scroller+and+Touch

Event propagation in mediumweight components

Hi,
There's an article "Mixing heavy and light components":
http://java.sun.com/products/jfc/tsc/articles/mixing/
It explains mouse event handling:
"Mouse events on a lightweight component fall through to its parent; mouse events on a heavyweight component do not fall through to its parent. "
What about mediumweight components? Are mediumweight components receiving mouse events like lightweight or like heavyweight components?
Is it possible to infer how the mouse events are propagated just by using JComponent.isLightweightComponent()?
Kari

What do you mean by sub-app . Are you using modules ? For regular situations you can set "bubbles" to true on the event.

Need More Mouse Events

[http://forums.sun.com/thread.jspa?messageID=10811388|http://forums.sun.com/thread.jspa?messageID=10811388]
During search over net I found the above thread and it seems to be describing the same problem which I am also facing. For my application also I need to capture all the mouse events while dragging. I tried the soluiotn mentioned at this thread to solve this problem by overrinding the below method in several ways:
protected AWTEvent coalesceEvents(AWTEvent existingEvent,AWTEvent newEvent);
Even after several attempts, I could not succeed. Can you please suggest how to do that. I was not able to reply to above thread so creating this new thread.
Thanks

I wanted to see if a timer based approach does indeed produce a smoother curve than just simply listening for mouse drag events. What I came up with below was the resulting test code. Lo and behold, using a timer does indeed produce a smoother curve. But it wasn't because it was capturing more mouse positions, it was because it was capturing less. Ain't that a kicker? Another interesting thing is that according to the source code, coalesceEvents is a no-op. The documentation, however, would have you believe that it coalesces mouse events as I thought it did.

Mouse Events on Disabled Buttons

Hi,
In my application I should make a disabled button to show a tool tip when mouse is entered onto it.
I'm using java.awt.container not Jcontainer.
I have searched in SDN forums and after reading some of the comments what I understood is �disabled Swing button can react to Mouse events but a disabled awt button can not react to mouse events�.
Is that true or did I not understand correctly?
And how would I be able to implement the required functionality in my
application?
Thanks.

Event propagation API

Hi,
I recently started using Flex and read through the, very extensive and well written documentation. I read about the event propagation mechanism and was rather stunned that only Objects that have a parent-child relationship take part in event propagation. At first I couldn't believe it but trying to connect to objects that were at very different parts of the display list showed, that the events really do not get delivered! Wouldn't it be better to have a more general mechanism that does not care about the wherabouts of the components? I mean, what if I want to synchronize some model objects that are not even part of the display list with some UI Element they have a relationship with? The target phase doesn't work because its not the model that throws the event (of course!). Or do I miss something here?
I was expecting a more subject-observer like pattern, that allows me to connect whatever I want with whatever there is left. So, how do I do that. Do I have to right my own little event dispatching library (what would not be so difficult, but I would rather use something that has already proven its liability)? Can anybody recommend me a good API for that or tell me that I am dead wrong and missing something important?
Regards,
Benni

Only DisplayObjects support bubble and capture propagation. In a tree of
regular Objects, as long as you attach a listener to the right object, you
will be able to get its events.
Bubble and capture are very dangerous as they break encapsulation. We only
use them for situations where the target is unpredictable like in mouse and
keyboard interaction. I would probably not use it in a data object tree.
Maybe if you provide a more explicit example of what you are trying to
accomplish and what you tried, folks on the forum can help.

Trying to create a surface with multiple images with mouse events

novice programmer (for a applet program)
hi trying to create a surface i.e jpanel, canvas, that allows multiple images to be created.
Each object is to contain a image(icon) and a name associated with that particular image. Then each image+label has a mouse event that allows the item to be dragged around the screen.
I have tried creating own class that contains a image and string but I having problems.
I know i can create a labels with icons but having major problems adding mouse events to allow each newly created label object to moved by the users mouse?
if any one has any tips of how to acheive this it would be much appreciated. Thanks in advance.

How to throw the mouse event to a upper level component?

For example: a panel using absolute layout, and there is a label on it.
Now when mouse clicked on the label, i do not want the label but the panel to get the mouse event , so that i can get the mouse click point's x and y in the panel.
How to implement it?
Thanks a looooooooooooot for ur help

Handling mouse events anywhere

Hi,
We have built an application with a Swing GUI and for automation and testing we would like to record all keyboard and mouse events to be able to play them afterwards.
The keyboard events can be recorded easily with a KeyboardFocusManager but for the mouse events I still need a solution.
The GUI consists of a JFrame containing several JPanels. When I add a MouseListener on the JFrame, its mousePressed and mouseReleased events are not called everytime I click somewhere on the frame. For example, when I click on a button inside one of the JPanels, the mouse event methods of the frame are not executed.
Can somebody tell me how I can easily capture all mouse events in the GUI without adding MouseListeners in every JPanel??
Thanks in advance...

I know how to use the Robot class, that's not really the issue.
What we are doing actually is writing keyboard and mouse events into a file.
Afterwards we use the Robot class to playback the events in the file. This is no problem, I just don't know how I can easily intercept ALL mouse events in the GUI without adding mouseListeners in each component in the GUI.

Allowing Mouse Events to "Fall Through" When Window Activated

I'm implementing a "tool pallette" in my application (much like tools in an application like Photoshop) and I want the user to be able to immediately click on options on this pallete without having to make the window active. Since Swing doesn't have an explicit "Pallete" window that would give this to me for free, I'm assuming I need to subclass JDialog to make this happen.
Even if window activation still must happen, it's crucial that the user only needs to click once to press the button on an inactive window.
I know I can detect WindowEvents like WINDOW_ACTIVATED by simply adding my own window listener, but I don't know how I'd go about having mouse events "fall through" the window listeners and cause the appropriate action on the underlying component. It's almost as if I need to tell the window itself to listen for nothing.
I thought glass planes may be the answer, but that doesn't seem to be what's preventing the intial click in an inactive window from falling through to the underlying component.
Any thoughts, comments, or experiences regarding this are greatly appreciated!

Such a simple solution to such a perplexing problem. You are absolutely right. It turns out I was experience a bug in my particular L&F. Trying this with the Windows L&F proves that simply changing from JWindow to a non-modal JDialog works. Now I'll have to go about getting the bug fixed in the MacOSX (Aqua) L&F so I have equivalent behavior across all our supported platforms.
Thanks for the quick response.

The solution to this problem was posted in the Swing forum. Turns out to be a simple difference of JWindow and JDialog, but a difference I wasn't seeing under all L&Fs (i.e., Windows L&F handles JDialog properly, MacOSX (Aqua) L&F seems to treat it like any other window... I've filed a bug with them).

How Keyboard & Mouse Events are handled in java?

Hi
How Keyboard & Mouse Events are handled in java?
Kindly brief, how a key typed in the keyboard is sensed and it is entered in JTextField?
or
Pls. give me some links.
Am going to send the events from external device (like keyboard) to OS and from that I need to capture that event in Java Swing?
Pls. drop in a bit. So that it will be helpfull to me.
Thanks in advance,
bee

Actualy am very much aware of using KeyListener and MouseListener. I am in need of internal details,
how typing a key in keyboard is captured by KeyListener? How the event is passed to java swing and and it is fired to keylistener.
Pls. help me.
Thanks
bee

JPanels are not reading Mouse Events

I created a basic Tic Tac Toe game, with individual "TicPanel"s inside a JPanel inside a JFrame object, however, none of the mouse events are working? Is it because the JFrame is receiving and doing nothing with the MouseEvents?
    private class TicPanel extends JPanel implements MouseListener
        private int owner; //-1 = none, 0 = O, 1 = X
        private Graphics g;
        private int num;
        ActionListener listener;
         * Constructor
        public TicPanel(int num)
            this.num = num;
            g = getGraphics();
            owner = -1;
        public void setX()
            owner = 1;
            g.drawLine(0,0,getWidth(),getHeight());
        public void setO()
            owner = 0;
            g.drawOval(0,0,getWidth(),getHeight());
        public int getOwner()
            return owner;
        public void mousePressed(MouseEvent evt){}
        public void mouseReleased(MouseEvent evt){}
        public void mouseExited(MouseEvent evt){}
        public void mouseEntered(MouseEvent evt){}
        public void mouseClicked(MouseEvent evt)
            System.out.println("works");
            listener.actionPerformed(new ActionEvent(this, num, ""));
            setX();
        public void addActionListener(ActionListener listener)
            this.listener = listener;

Usually this is done with the addMouseListener(...) method.
Oh, and please read the Sun graphics tutorial as this is not the way to do graphics in Swing. You do not want to get the Graphics object via getGraphics method but instead do your painting in a paintComponent override method and get your Graphics object from the parameter passed to this method. The tutorials will explain all.
