Detecting missing mouse clicks?

There are some times when a user clicks on a movie clip in my
SWF that the mouse click goes undetected by any of my mouse event
handlers.
I even added a MouseClick listener at the root sprite of my
SWF.
Is there any way to detect where this mouse click is going,
and why it is not being detected by anything?
NOTE: I have *only* seen this happen so far when a user
clicks on a movie clip that I have dynamically loaded. The movie
clip is not playing, and I am manually calling gotoAndStop() on the
movie clip various times. Not sure if that is related.

please don't cross post.

Firefox missing mouse clicks

I have updated both my desktop (Win7) and my laptop (WinXP) to Firefox 9.0.1 (from 8.0) and both are suffering from this issue.
about 99% of my left mouse clicks seem to get ignored, but middle and right are both perfectly find. Left button operates correctly in all other programs.
The mouse works correctly in the taskbar/menus/tab bar/scroll bar, but stops as soon as I am inside the page display area.
Sometimes if I click continuously for 10 seconds I get an ok click, or sometimes I have to use a different program for a minute and then come back, then I can get 1 or 2 clicks before it stops working.
Currently navigating using tab, and shift+tab.
This is very very annoying, has anyone else noticed this after update? or have any ideas?

My current issue is that if the simulator is frozen (system time is cycling within a 100ms window) mouse clicks on buttons are getting lost.OK that's an entirely different kettle of fish. Firing an action does require that the mouseReleased be later than the mousePressed, and that both be over the button.
Consider ths scenarion in any normal application that doesn't interfere with the system time. The user presses the mouse over some other component, drags over to the button and releases it. Next, the user presses the mouse over the button, drags off the button and then releases it. This isn't supposed to trigger the button's ActionListener#actionPerformed.
With the system time looping, how does the runtime know that this isn't the case?
I can see the button border change when I move the mouse over the button,that's rollover, triggered from mouseEntered. timing is not an issue.
but the mouse click is lost (button does not get depressed).See above.
Sometimes it works fine for a few mouse clicks and other times several mouse clicks will be lost in a row.See above.
It seems random.In a way, it is.
This seems to be more prevalent with buttons than capturing a mouse click on a panel where I do 2D drawing. Not sure why.Could be just human susceptibility to guesswork, or may actually have something to do with the occasional additional processor cycles involved in the custom painting. Since you haven't described the frequency of repainting nor its complexity, that guess is my susceptibility to guesswork ;)
When I put the simulator into Run mode, it works perfectly, never missing a click.Of course it will.
Anyone out there have any insights into what might be going on under the hood inside Java/Swing with mouse events and the system clock?See above.

Detecting a mouse click on any (all) child components...

Hey All,
I am writing a number of compound GUI elements that i want to make focusable when you click any part of them. (i.e. a JTextArea inside a JScrollPane, coupled to a JTextField to provide input to the JTextArea).
Is there an easy way to detect mouse clicks on child components of a JPanel?
My current code is:
m_oInputBox.addMouseListener(this);
m_oOutputBox.addMouseListener(this);
m_oScrollPane.getVerticalScrollBar().addMouseListener(this);
This detects most of the mouse clicks, but not those on the buttons that form the scroll bar ends or the scroll bar slider when it is present.
Any way tou can detect clicks on these too??
Iso

P.S. It does actually detect clicks on the scroll bar slider - just not onthe buttons that form the slider end caps (up/down).

TreeSelectionListener detect if mouse click

hi,
i've got a JTree and I'm using a TreeSelectionListener to carry out different actions when the user clicks on nodes. however, sometimes i want to change the selection on the tree programmatically (i know how to do this bit), and for the action associated with clicking on the node not to happen.
is it possible within the valueChanged method of the TreeSelectionListener to determine if the selection was changed by a mouse click or programmatically? or can anyone think of another way to approach this?
cheers for any help!

You can't do that with the event, but if you create a boolean variable named for example
boolean programSelection = false;
and when you change the selection programmatically you put the value to true. In the method valueChanged you have to test the value of programSelection like that :
public void valueChanged(ChangeEvent e) {
   if (programSelection) {
      // the code when the selection come from the program
     programSelection = false;
   else {
      // the code when the selection come from the user
}

Missing mouse clicks

I have no idea why, but some mouseclicks are missing here. I can click stuff, but it doesn't do anything. This is maybe every 10th click. Any idea why this happens?
Thanks

For example double clicking in Finder to open an application, clicking a link in safari, clicking on a window... everything...

Mouse clicking

Hi all!
Maybe it's too easy question, but I really appreciate your help!
What listener should I use if I want to detect every mouse click
wherever on the screen? When I add MouseListener to any Component,
the MouseListener method mouseClicked is called only if I clicked
on that component!
many thanks

Mouse clicks not detected on JTabbedPane

Hi all,
I have a JPanel placed inside a JTabbedPane. I want to double-click on the JPanel and bring up a JDialog. This works fine if the JPanel is not in a JTabbedPane, but if it is on a JTabbedPane, then the mouse clicks are not detected. I'd greatly appreciate any help you can give me.

Here is a sample program that seems to work:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;
public class TestInternalFrame extends JFrame
     public TestInternalFrame()
          JDesktopPane desktop = new JDesktopPane();
          setContentPane( desktop );
          JInternalFrame internal = new JInternalFrame( "Internal Frame" );
          desktop.add( internal );
          internal.setLocation( 50, 50 );
          internal.setSize( 300, 300 );
          internal.setVisible( true );
          JTabbedPane tabbedPane = new JTabbedPane();
          internal.getContentPane().add(tabbedPane);
          tabbedPane.setPreferredSize( new Dimension(300, 200) );
          JPanel panel = new JPanel();
          tabbedPane.add( "Empty Panel", panel );
          panel.addMouseListener( new MouseAdapter()
               public void mouseClicked(MouseEvent e)
                    System.out.println(e.getClickCount());
     public static void main(String args[])
TestInternalFrame frame = new TestInternalFrame();
frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
frame.setSize(400, 400);
frame.setVisible(true);

Detect mouse clicks or keyboard events on desktop or everywhere

Hi,
What I have to do is to start the application minimized in the system tray. Then the application must be listening for crtl+shift+left mouse click in any part of the desktop or an opened application, when that happens, I have to show a window asking if the user want to take a screenshot starting in the x,y point he clicked and then take the screenshot.
What I don't know how to do is to detect the mouse and keyboard events when the application is supposed to be running minimized in the system tray.
How can I do that? Can anybody give me a hint?
Thanks in advance.

It's not possible with plain Java. You will need native code for this. Take a look at JNA.

Detecting mouse clicks in editable cell of JTable

Hi everyone :)
I thought that this question might have been asked before, but I have searched the forums extensively and have not been able to find the solution.
What I want to achieve is to detect single and double mouse clicks on JTable cells (that are editable).
For example, I have a JTable and there exists within it an editable cell. If the user clicks on it once then that cell goes into edit mode, and the user can type directly into the cell. I have already successfully implemented this.
However, what I also want to do is detect a double-click so that I can pop up a dilaog that shows a list of default values that the user can select.
So here is what I want;
1. User clicks on the cell once.
2. Cell moves into edit mode.
3. If the user clicks again within a certain time interval then cancel edit mode and pop up a dialog containing values that the user can select from.
I think that to do this I need to be able to detect mouse clicks on the cell that is currently being edited. So far I have been unable to discover how this is done. I have even tried extending JTextField to get what I want, but with no luck.
Any help would be greatly appreciated.
Kind regards,
Ben Deany

Thanks for the reply.
Unfortunately, it is not possible to call 'AddMouseListener()' on a cell editor. You are only able to call 'addCellEditorListener()' and that only allows two events to the broadcast (edit cancel, and edit stop).

How to detect mouse clicks on desktop?

Hi All,
I need to detect mouse clicks on the desktop and find out mouse position on the screen. How to listen to mouse events if I don't have any swing components like containers, panels, windows, etc? All things like "addMouseListener" are supposed to be with such components. But my program is running in the background and it doesn't have any graphical interfaces. So, I need to detect if a mouse button is pressed at any position on the screen.
Thanks for any help!

Why? What program feature do you intend to offer, by knowing what a user clicks on (besides the application itself).Hi, well what I have to do is to start the application minimized in the system tray. Then the application must be listening for crtl+shift+left click in any part of the desktop or an opened application, when that happens, I have to show a window asking if the user want to take a screenshot starting in the x,y point he clicked, once done, I have to take an screenshot...so on.
How can I do that? Can anybody give me a hint? Thanks in advance.

How to detect mouse click event?

Hello,
I would like to have a vi to detect left, right and no mouse click. I mean that in the vi attached, Button2 should be 0 (no click), 1 (left c.) or 2 (right c.) depending on the event occured in i-1. cycle. My vi is the modyfied version of the one found here:
http://www.ni.com/example/27663/en/
Sometimes it works fine, but another time nothing happens when I click.
I think the main problem is with the execution times at the for loop and event structure.
Could you help me how to deal with the problem?
Thanks you!

Hi VampireEmpire,
Your For loop iterates twice. If an event occures during first iteration everything is fine - Button 2 refreshes during second iteration. But what happens when an event occures during second iteration? Does Button 2 have a possibility to refresh?
1. Do you see the problem now?
2. And if you do - do you really need For loop? I would suggest you trying removing it and connecting shift register to the while loop.

Detecting mouse click on a line

I'm learning making GUI apps in Java.
Here is my problem. Suppose I draw a line on a JPanel. If I want to find out if the line is clicked or not, what is the best way to do it?
I did some research, looked at API. If I suppose my line is Line2D, then since its a line it doesn't have an area, so its contains method always returns false (..from API). So i dig around some more and came up with the solution of getting the shape from the stroke and calling its contains method.
This is a code for what i mean..
private Line2D.Double testLine;
//mouse clicked event
public void mouseClicked(MouseEvent e) {
        int x = e.getX();
        int y = e.getY();
        BasicStroke stroke = new BasicStroke(4);
        Shape testShape = stroke.createStrokedShape(testLine);
        if(testShape.contains(x,y)){
            System.out.println("this will be printed if clicked on line");
    }Well, the above solution works fine.
Is it the right way of doing it or is there a better way around for this?
Any help will be appreciated.
Thanks.

When trying to test if a line was pressed I usually test if the distance between the mouse coordinates and the line is smaller than some constant (usually 5 pixels).
For this you have to write your own code to calculate the distance between a point and a line.

Detect mouse click in FlashPlayer ActiveX

I'm hosting the FlashPlayer ActiveX control (Flash9f.ocx) in
a VB 6 application. The OCX exposes the following events:
FlashCall, OnProgress, OnReadyStateChange and FSCommand. It does
not expose the traditional Click, MouseUp or MouseDown events (for
example) so is there a way to receive mouse click events in the
hosted application?
Also, I am unable to find any documentation on the FlashCall
event. Any ideas what it is and how it works?
Thanks to any and all.

Scene Object Mouse Click Cooordinates (xyz)

Anyone run into and figured out a method for detecting the scene coordinates (xyz) of a mouse click on an object? Very simply I have a two-dimentional plane (ground) and a box (character) that begins at x0,z0 (directly "on" the plane). I'd like to mouse-click on the plane and move the box to that spot based on the scene x,z. After a few days of trying I'm no closer to solving this seemingly straightforward issue. Anyone wanting to do "click to move" for 3D assets rather than keyboard or mouse drag will need this. Having no real documentation or code-view into the API isn't helping. Am I missing something that should be obvious?
I have to say that I'm a little surprised that there hasn't been any "official' responses to any of our questions. I think the Proscenium team has done a fantastic job so far with this framework. It's simple to setup and get going yet powerful by giving you great depth into the heart of Stage3D without stepping on the framework itself. But, it's not that hard to imagine that there are a lot of us wanting to move into this "new" medium but feel teased by what we've been shown ('code'us-interruptus?). At the moment you either have to know/learn what you need to create your own framework (a big task if you'v enever done it) or use someone elses. In my opinion the existing third-party options are bloated and unwieldy for my purposes. At a time where "everyone" is trying to quickly get their ideas to market with this new tech it's unfortunate we can't get a few simple questions answered. Seriously, if you have a "discussion" and see that any given post has 100 or more views but zero replys, that's not a discussion. You're just talking to yourself.
My appoligies for turning this into a rant.

Thanks for the reply pio.
I tried that angle (pun only slightly intended) and was successful in identifying the object directly “behind” the cursor using scene.pick, even getting that object’s world position. But, if my ground plane is positioned at 0,0,0 I can only get that position directly from the object, which doesn’t do me any good. What I need to know are the coordinates of the point where the cursor bisected the object, relative to its center, from the origin of the camera view. That would tell me the direction and distance I would need to move another object within world space.
I thought I had come up with a solution but the immediate problem I ran into was the closed nature of the framework. So, after a few days of unproductive grumbling I decided that the only way I was truly going to accomplish what I wanted was to build everything from the ground-up. I still think Proscenium has great potential but I’m done waiting for a RC. For anyone who’s thought about digging into heart of stage3D and building their own framework, but thought it would be incredibly difficult, well, it is. At least it as for me but anyone who would find it easy probably isn’t in this forum. After climbing a steep learning curve (AGAL and I are back on speaking terms) I finally got going and am extremely pleased with what I’ve accomplished. Granted, I did spend a lot of time initially banging my forehead on my desk but I finally “got it”, and with only a slight concussion.
The resources are out there.
