JComboBox in JTable to activate when double-click instead of single-click
I like to know if it is possible to change the default behaviour of JComboBox within the JTable,
such that instead of single click on the JTable cell for the combo box's popup to appear, I double click on it instead.
If it is possible please give some advice.
Thanks.
I couldn't get to settings because I couldn't scroll and don't know where that is located. I just saw a similar question from someone else. Three clicks on home button worked to turn off voiceover !! Phew!

Double click instead of single click
recently like a month ago i started noticing when i ried to open a new tab in firefox or close,i opened two new tabs or close two tabs then i found out it wasn't firefox is that when i single click on something i guess ny computer recognizes that as a double click and that's what it does,it double clicks on the icon,video or whatever i click on,can anyone tell me how to revert this to its default configuration,by the way i didn't mess with it or tried to change it or what ever,most of the times it double clicks on anything but not all the time
@karantani: exactly as cfr said: it happens after some time and without any warning. If you're not sure just try another mouse. 5years is hell of a lot for a mouse if you use it on everyday basis for many hours. I even had this on new Logitech mouse just after couple of months (they're all doing just shit nowadays, I miss days of old heavy, robust keyboards and mouses, of electronics like Walkman - it was some nice engineering, everything was working just fine for many, many years. Right now your lucky if product will hold it's planned obsolescence). There is a lot you can do, I fix mine by sticking piece of paper to lift badly designed buttons, but in many cases switches just have enough.

How to separate double click action and single click action
in my mouse action listerner for JTable.
i do two actions, when user doule click column header, sort the column,
when single clicked, select all cells in this column.
but when user double clicked, the action attached with single click also triggered.(column sorted but also selected)
how to separate them.Ok, so despite my earlier suggestion being basically the only solution offered anyway on the web it appears that Lokust is correct and that the single click operation would be performed as well as the double click one. to get round this u have to implement a Timer, i'm not going to post my whole code here because most of it is irrelevent, just add this code in the correct places and it should work fine. apologies to all format junkies for not using code tags!
import java.util.Timer;
import java.util.TimeTask;
public class WhateverClassName implements MouseListener {
private Timer t;
private boolean doubleclick;
myTable.addMouseListener(this);
public void mouseClicked(MouseEvent e) {
t = new Timer();
if (e.getClickCount() == 2){
doubleclick = true;
else if(e.getClickCount()==1){
t.schedule(new MyTimerTask(),500);
/*You need all these methods as well */
/* (non-Javadoc)
* @see java.awt.event.MouseListener#mouseEntered(java.awt.event.MouseEvent)
public void mouseEntered(MouseEvent arg0) {
/* (non-Javadoc)
* @see java.awt.event.MouseListener#mouseExited(java.awt.event.MouseEvent)
public void mouseExited(MouseEvent arg0) {
/* (non-Javadoc)
* @see java.awt.event.MouseListener#mousePressed(java.awt.event.MouseEvent)
public void mousePressed(MouseEvent arg0) {
/* (non-Javadoc)
* @see java.awt.event.MouseListener#mouseReleased(java.awt.event.MouseEvent)
public void mouseReleased(MouseEvent arg0) {
class MyTimerTask extends TimerTask{
/* (non-Javadoc)
* @see java.util.TimerTask#run()
public void run() {
if(doubleclick){
System.out.print("double click");
else{
System.out.println("single click");
t.cancel();
This assumes that for it to be considered a double click user has to click twice within .5 seconds.
Let me know if that works or not, sorry its a bit messy! -
Making the Dock require Double-Click instead of Single
Is there a way to make the Dock require a double-click instead of a single-click to open applications. It would be great if the single-click would still focus the desired application. The prevents users from accidentally opening potentially large programs.
Sorry. I meant that if an application is already open the single-click should focus it (bring it to the front) which is the current behavior.
It is two easy to open applications. I have IDE's on the dock that take a lot of resources to start and I find myself accidentally opening them when wanting to open Textedit or a terminal. A double-click would allow the user to correct after the first click thus not opening the wrong application. -
Need Double quotes instead of Single quotes in output XML version header
In XML output generated by XDODTEXE executable, its observed that header row looks like this:
<?xml version = '1.0' encoding = 'UTF-8'?>
It should look like this:
<?xml version="1.0" encoding="UTF-8"?>
Browsers like IE deceive. Opening the XML in Text editors show single quotes and spaces.
Data Template and XSL template files have proper headers with double quotes.
The output XML file is rejected by a Government Authority as parsing the header line fails.
Are there any ways to configure this?I dont know if this has anything to do with my problem or not, but I thought I should add this:
When a user is filling out the form that has the textarea, they put whatever text they want into the textarea field.
textarea name="text"></textarea
Then, they click on a 'Continue' button and the system shows them a preview of what they are about to have inserted
into the database.
Within the code on this preview page is a hidden field, which holds the contents of their textarea data so it can be
passed on through the process once the user verifies the preview.
This is done using this: input type="hidden" name="text" value="<cfoutput>#text#</cfoutput>"
Like I said, I don't know if that has anything to do with this problem, but thought it might be good to mention it

Double redirect instead of single why?

After processing I forward to another jsp. This doesn't happen though for some reason i just end up back in the same action. Anybody got any ideas why or how to solve this?I did mean redirecting (forwarding) ciea the requestdispatcher.

Magic Mouse single click double clicks and drops dragged images
Last few weeks my Magic Mouse has started behaving strangely. When selecting something with a single click the mouse seems to double click and open the item instead of just selecting it. Very frustrating. When dragging anything across the screen it always drops the item halfway there.
What is going on? Software? Hardware? I have no 3rd party software installed and have tried various double click speeds with the same result.
Anyone have any ideas? Thanks.A lot of people have encountered this, Tom, myself included (see discussion here for instance: http://discussions.apple.com/thread.jspa?messageID=11547453�).
It appears to be a bug in the OS. Annoying, but until Apple fix the problem, it's something we're unfortunately going to have to live with. Sorry I can't help you further. -
Doubt - mouse double click invokes both single and double click
Hi Friends,
I added mouse listener to a java component. In the mouseClicked() method, I have implementation for both mouse single and double click. When I try to double click that component it invokes the single click method first and the it invokes the double click method. My problem is when I try to double click that component it should invoke my double click method alone not single click too.
I'd be very grateful if someone can help me.
Thanks and Regards,
Sangeetha JYour problem: a double click is two single clicks. The first click will always fire a single-click event. How's the computer supposed to know that another click is to follow?
All I think you could do is to instantiate a timer in the one-click method, set to whatever amount of time you think a double-click should take. If you get a second event while the timer's still active, it was a double-click and you can stop the timer and do the double-click action. Otherwise your timer should execute the single-click action after it timed out.
But this will make your GUI look like it's responding slowly to single-clicks. -
Mouse double click on single click
My mouse has been double clicking on a single click since changing to Mavericks 10.9. I have tried different mouse brands from Apple to Rapoo and everything inbetween. I have played with the mouse settings and rebooted, reset the pram and nothing works. It's very frustrating as a graphic designer to be slowed down because of a mouse.
Has anyone ad this problem and has the solution to it?
ThanksFrom the menu bar click on Go > (Hold option down) Library will appear, click it.
In the Library goto Preferences
Locate the following files and delete them.
-com.apple.driver.AppleBluetoothMultitouch.mouse.plist
Restart the computer and test.
Hope this helps. -

[Solved] Gwenview 5 lost icons and single click
Hi,
I don't use KDE but I do use Gwenview. Since upgrading to 5 Gwenview has lost some icons (outlined in red below), and I now have to double click on directories and images to open them instead of single click. Is it possible to fix these issues without installing a full KDE desktop?
Thanks, Jamie

Single-click on a Tree not cancelable
Hi,
I have a component that includes a Tree, and the Tree uses a
custom TreeItemRenderer. The render extends the default one, and
adds a small graphic next to each Tree node's label.
If users click the graphic, I'd like to prevent the default
single-click behavior of the tree. For example, I'd like to prevent
the node being selected.
I've found that MouseEvent.CLICK is not cancelable, so
preventDefault() has no effect.
Is there a way to prevent the Tree from reacting to the
single click, if the single-click is on the graphic in my item
renderer?"Marc Missire" <[email protected]> wrote in

Setting mouseChildren to false on the image might work.

Problem while displaying the data when double clicked on JTable element
Hi All,
i have one List box( JList ) and one table (JTable). Both JTable and JList are positioned on the same Frame. I am able to drag the elements from JList to JTable and also i have added the mouse click action on both List box and JTable.
if i double click on JList element, that will popup one dialog box.
if i double click on JTable cell element that was dragged from JList, that will popup same dialog box which was opened earlier for JList action.
But my problem here is:
Suppose if i drag the four elements one by one from JList to JTable and (after four elements dragged) double clicked the first element which was dragged first that displayed the popup dialog box structure correctly but the data displayed in that was not correct. It is showing the data of recent dragged element( i.e, fourth element).
But if i double click on JList element that is showing the correct data according to the double clicked element.
What might be the problem here, why it was not displaying the correct data when double clicked on JTable element.
Please help me here.
Many thanks in advance.
The following code is used in mouse clicked event method of JList
private void listMouseClicked(java.awt.event.MouseEvent evt) {
if(evt.getClickCount()==2){
AssigningResourcesUI assignResource=new AssigningResourcesUI(this,true);
assignResource.show();
} AND The following code is used in mouse click enevet method of JTable.
private void tableMouseClicked(java.awt.event.MouseEvent evt) {
if(evt.getClickCount()==2){
int row=table.rowAtPoint(new Point(evt.getX(), evt.getY()));
int col=table.columnAtPoint(new Point(evt.getX(), evt.getY()));
if(row==-1||col==-1){
return;
Object obj=table.getModel().getValueAt(row, col);
if(obj==null||(obj.equals(""))){
}else{
AssigningResourcesUI assignResource=new AssigningResourcesUI(this,true);
assignResource.show();
} Thanks & Regards,
Maadhav....
Edited by: maadhav on Jul 1, 2009 7:22 AMI doubt it is related to your problem but:
int row=table.rowAtPoint(new Point(evt.getX(), evt.getY()));Why are you creating a new Point? Just use evt.getPoint().
Object obj=table.getModel().getValueAt(row, col);Don't get the data through the model method, get the data through the table method:
Object obj = table.getValueAt(...)
This way it will work even if the table happens to be sorted.
Instead of creating a AssigningResourcesUI object, just disply the value retrieved from the model. That way you know whether the problem is with the mouse event code or your UI class. Like Walter suggested above I"m guess the problem is with your UI class. -
When I open up iphoto and click on the events tab then double click on an event, it used to show minis of all the photos in that event. Now it shows only one photo at a time. How do I get it back? Can you help?
On the bottom bar of the window (on the left iPhoto 11, on the right in other versions) note the slider. Drag it left.
