Mouse Double Click on an editable cell of JTable

Hi Pros:
Maybe this is an old question but no answser from Forum.
I have a JTable with adding MouseListener. I tried to put double click behavior on nay row in the table. The problem was that this action can obly work on the uneditable cell and do not work on editable cell.
Anyone have ideas and help me.
Thank you!

Hi Wang,
I have a problem similar to the one you have some time back.
I have a query for which I need to use PreparedStatement .The query runs likes this :-
String str = " Select ? , ename from emp where deptno ? ";
The values of ? need to be assigned dynamically.
But I cannot create Prepared Statement from this query .
If you have got answer to your questions can you inform me at
[email protected]
Thanks in advance

Double click does not edit cell

One of my users: double-clicking a cell is expected to place the focus into the cell for editing, but the expected behavior isn't happening. Cursor remains unchanged.
It's not the mouse; I tried a couple. It's not plist, deleted both.
It is something totally simple but what?

Complementary questions :
(1) How is the app behaving if you run it in an other user account ?
(2) Was Mac Os updated to 10.6.2 thru "Applications Update" ?
If it was, it may be a good idea to apply the combo updater available from:

How to capturing Mouse double click action?

Hi all,
how can we identify the "mouse double click" action?
MouseListener has methods for only mousePressed,released,clicked (single).
Thanks in advance..

Sojan

Hi,
Thanks it worked ..
e.getClickCount() value increases if we keep on clicking on the component, is there anythning wrong by interpreting double click as
"e.getClickCount() >=2 "?

Distinguishing b/t two single mouse-click and mouse-double-click

Hi,
I am curious to find out how Forms will distinguish between two single when-mouse-click events and a single when-mouse-doubleclick event. Is it simply a timing issue or is there more involved i.e. the 'co-ordinates' of the mouse. Thanks in advance for any opinions given,
regards,
Kevin.

The difference is same as the difference of Apple and Orange.
Its depends on O/S and event management within OS kernel.
You can change the timing in Control panel of mouse double click.

MOUSE DOUBLE CLICKING

I have an hp mouse...however it says product of china on the back..It does look like an hp mouse though..
Anyhow..it's doubleclicking..it's driving me crazy..
I've had the mouse for a few years..
It just starting doing this..
I"m running XP
It is a USB..with a red light under it...with an optical eye?...Not sure if that's what they call it..
Please help..Are there drivers I can use to fix this...
I"m not sure if a windows update..might have done this..
Many thanks..

Hi kittylondon,
I understand your mouse is acting like you are double-clicking even though you are only clicking. Take a look at the following, Troubleshoot mouse double-clicking when you single-click. The document also applies to Windows 7 and Windows Vista, so you will have to make sure you are referencing only the portions that apply to Windows XP. I hope this is of help to you. Best of luck. Have a wonderful day.

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).

Needs double click to edit cell in JTable

I know this is bad design but there's no other way that I could possibly meet the requirement which is to have dynamic components. Anyhow, the requirement is to have any kind of components(e.g. TextFields, Combobox, Regular expression fields, a panel with a number of checkboxes) in a table cell in the same column. It would have been easier to do this by using the the DefaultCellEditor, with the 'panel containing a number of checkboxes' I cannot use it.
I already have an implementation for this requirement. There was no problem with it when we used Java 1.5. But when we shifted to Java 1.6, I noticed that I need to double-click on a cell so that I can edit it. I did not notice this behavior at all with 1.5. What could have changed in 1.6?
Below, are my (trimmed-down) codes:
//TestComponent.java

textFieldMaxLength * 13, this.componentHeight);
          oText.setPreferredSize(fieldSize);

Usb mouse double click

Hi,
Im using fluxbox as window manager and after some upgrades the mouse very often doing double click, if I click only once. On touchpad is all right, so I dont know where is the problem. I tryed change xorg configuration - other protocol and some options, but nothing helped. I also tryed change speed double click, but nothing changed too.
My xorg config is now:
Section "InputDevice"
Identifier "USB Mouse"
Driver "mouse"
Option "Device" "/dev/input/mice"
Option "SendCoreEvents" "true"
Option "Protocol" "IMPS/2"
Option "ZAxisMapping" "4 5"
Option "Buttons" "5"
EndSection

Magic Mouse: Double-click function

I have "secondary-click"(right) activated on the "magic mouse" and it's great if I want to open a drop-down list on a page.
However, on the "mighty-mouse" which I had before, the "right-click" was set up to act as a "double-click" which was very handy for opening documents and folders etc.
Is there any way to set up the "magic-mouse" so that a "right-click" will act as a "double-click"?

You could try a third-party driver like BetterTouchTool (http://blog.boastr.net/?page_id=1722)

In Yosemite, Magic Mouse double-click function doesn't work

On my iMac running Yosemite 10.10.2, the double-click function on the Magic Mouse no longer works. So to open a folder, or anything for that matter, I must always do click-control ---and that doesn't work for everything. For example, I can't double click on a character in Glyphs, so this renders Glyphs useless. And so on... I have gone into preferences to see if anything was amiss in the settings, but everything checked out fine. Is there a fix for this, or do I have to wait for the next upgrade for Yosemite? Help! Thanks... --Royce

What's the answer to this mouse problem, please? Why does my double-click no longer work on my magic mouse since downloading Yosemite 10.10.2 to my iMac?
What's up Apple?

Trying to catch mouse double click

Using come code in the API 1.3 documentation, I created a JList and am trying to catch when a user double clicks on an item in the list. I have the following snippet of code:
public void mouseClicked(MouseEvent e) {
if ((e.getClickCount() == 3) && (e.getSource() == list1)) {
int index1 = list1.locationToIndex(e.getPoint());
System.out.println("Double clicked from the left list on Item " + index1);
When I double click on an item in list1, it prints out the output line twice as in:
Double clicked from the left list on Item 1
Double clicked from the left list on Item 1
How can I get it to run the code only once. I'm not sure why it's running it twice. Any Ideas would be helpful. Thanks....
Matt Menard

I've used similar procedure with success in JDK1.3.1. Without seeing the rest of your code, the only thing left for you to experiment with is to call the consume() method if the count is greater than 1. I did notice that Java mouse event handler leaves much to be desired. For example, the mouseentered and mouseexited events kept getting fired even tho the mouse has entered and never leave.
