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?

Setting mouseChildren to false on the image might work.

Single click on flash is not working for IE

Any one know why single clicking on flash movies is not
working in IE but works in other browsers?
IE will only work with a double click. Any work around for
this IE problem

The single click issue is (I believe) related to an Active X
change Microsoft made in an IE "patch."
This might be what you're looking for:
http://www.amarasoftware.com/flash-problem.htm
There are many variations on this fix, but I believe you have
to get the object and embed statements out of your HTML file and
put them in a Javascrript file that is called by your HTML file.
I have successfully made the change to a few pages, but not
CF pages.
Hope that helps.

Hi Experts,
I have a problem ,please help me.
I need event is trigger on single click on node of simple tree.There is event of double click but i need on single click only.
If you have any test program please forward it also.

i dont think for single click you can get any event in simple list... you can make hotspot on by this way single click will trigger the at line-selection event.

Windows 7 classic shell without single click??

I have 700 windows xp machines in a retail environment that I am prepping to swap out with Windows 7 machines. These xp machines are joined to our domain, and fairly locked down via group policy. I am in the process of putting together our new
Windows 7 image and building the group policies. Our goal is to maintain as much of the same look and feel that we have with our Win XP machines for this application.
That being said - I have enabled Windows Classic theme (by leaving UserConfiguration > Administrative Templates > Control Panel > Personalization > Force a specific visual style or force Windows Classic blank). This seems to work just fine.
I have the expected results for background, start menu, window appearance. What is confusing me is - my mouse somehow got set to single click. I do not want this. It seems to have happened with turning on windows classic?? I haven't
been able to find a GPO or GPP (or registry hack, for that matter) to turn it off.
I look in Explorer > Folder and search options > Click items as follows - Double-click to open an item is the radio button that is marked active. I was able to set my staging user (non admin level) to a local admin, re-login, click Single click
to open an item --> click apply --> click double click to open an item --> click apply and ok. Now things are as I want them. It seems that by manually making this change it does the trick. I won't have this luxury in the field.
Any input as to a workaround or what is actually going on would be greatly appreciated.
Thanks
sb

Hi,
To disable the "single click", you need to disable the GPO setting "Turn on Classic Shell" under the node given below,
User Configuration\Policies\Administrative Templates\Windows Components\Windows Explorer\Turn on Classic Shell

I have to "single-click" twice (not double click) to open an item in the Dock.

Can someone confirm if this is Expected Behavior?? (OS = Mavericks)
If you have Assigned an application in your Dock to a Desktop & Display in the application's Dock >> Options (ex: Assigned To: Desktop on Display 2):
Click once on the application icon in the Dock, the application's Menu will populate on the top of your screen, but not the application itself (yet), click the application icon a second time, the application will now show too.
Docked Applications that do not have an Assigned To: Desktop & Display in the Dock options, you only need to single click.
FYI:
For odd Dock behaviors otherwise try this:
You may have a corrupted Dock preferences file.
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Preferences/com.apple.dock.plist (plist = preference list file)
Click Go then move the com.apple.dock.plist file to the Trash, or move it to your Desktop.
Restart your Mac and see if the behavior is resolved. You will have re-configure your Dock settings.

From where are you launching Mail? The only place, unless I've missed or forgotten something, you can launch an application with a single click is from the Dock. Is this what you're doing, or are you attempting to launch Mail from the Applications folder?
Regards.

There was away (before Mavericks) I could single click on an email and it would highlite but not open. I could either delete or second click and the email would then open. Can anyone tell me how to configure the prevue pane to that end with Mavericks?

There was a way (before Mavericks) I could single click on an email in the "prevue pane" and it would highlite but not open. I could then either delete it or click again and it would open. With Mavericks that doesn't seem to be available making it impossible to delete an email in the prevue pane before I open it. Its frustrating to have to go through all the monkey motions when I know I want to delete it from the get-go. Does anyone know who to configure for that operation? I'm using an iMac.

Wow, have you ever seen 1 Billion in hard cash? If not, I assure you it exists as well.
Try not to pick apart what others write because you "have not seen it."
I run TWO programs for protection of my MAC now and have been for sometime b/c developers of them become complacid thinking MAC is impermeable.
My MAC locked me out of it and two externals and when I finally did get back into them Norton Anti-Virus found a "worm." When I asked the program to find the origin, it was traced back to an email, as you said, that I opened unintentionally. I still have two external HDs for backup and a cloud backup now.
When ClamX ran after Norton was finished, ClamX found what it called as "spyware," and it's origin was in my email also. I tried to delete the emails after the programs (both) identified the infected files, however once deleted and the computer is restarted, they were still there because I ran the scans again.
Now since we are no longer talking about how to turn on and off the view pane in apple mail; riddle me this, why can't the developers of these antivirus and antispyware/malware programs get together and develop ONE PRODUCT that catches 90-95% of the viruses/worms/spyware/malware ect that get onto MAC's? Is it because they are too busy thinking they don't exist?
I still run both programs and feel protected between the two. If Norton said it was a "worm" then I believe it was a worm and if ClamX called it "spyware" then I believe it is spyware.
I had to wipe my MAC and do a fresh install to get it working again, then I had to open one of those externals (which was very, very difficult) multiple times until finally it displayed the message "you can view, but not change the data." I exported as much as I could to my cloud and I had to format both of those too.
I still run both programs as I feel protected between the two. If Norton tells me it is a "worm" then I believe it is a "worm;" if ClamX tells me it is "spyware" then I believe it is "spyware." If it happens again, which my hope is that it won't, I will be more than happy to send the infected files to you!!
Try not to "forum rage." Support forums to post experiences and find answers, not nit-pick or claim not existance b/c you have not experienced it for yourself.

HT204053 I had Snow Leopard and was using iWeb and Filezilla for my website (not MobileMe). Wanting to move to single-click publishing, I now find it is not supported by iCloud and Mountain Lion. I feel cheated, having bought it mainly for this purpose!

The other thing they don't tell you is that Mountain Lion disables OfficeMac, and I am considering uninstalling it for that reason - do I get my money back?!

You stated; "Mountain Lion disables OfficeMac"
That is not true.
Mountain Lion does not have Rosetta so it is not capable of executing PowerPC code. If you have MS Office 2004 that is coded in PowerPC code and will not run in Mountain Lion. What you need to do is upgrade to an Intel version of Office.

SetRowSelectionInterval() not working on single-click in JTable

I have code that tries to move the highlighted row in a JTable back to the line you just edited instead of moving to the next line when you press enter after editing a cell (like you would normally see in a JTable or any spreadsheet program). If you double-click in the cell and edit the name, the code works correctly, but if you only single click the cell and enter the name, the code doesn't move the highlight - even though I know the code is being executed.
The code is nothing more than:
if(row == 0)
setRowSelectionInterval(0,0);
else
setRowSelectionInterval(row-1,row);
with row being the row you want to set the highlight to.
Does anyone know why this would work for a double-click edit of a JTable but not a single-click?

even though I know the code is being executed.How do you know that? Do you have a println immediately before the if (row == 0)of the code sample you gave us?

Single Click versus Double Click Action not working

Hello, having an issue with actions on symbols.
I have symbols that when clicked play at a specific location on the timeline.
Tthe first symbol uses single click (how I want it)
The rest of the symbols also use single click, but when I test the animation they require double click (even though they are coded to be single click)
Any ideas?
Here is a testing location for the animation:
http://www.contentx.com/DSU_discovery/MainAnim.html
Ideally I want single click on all the symbols. The double click is confusing.
Thanks!
zack

Hi, Zack-
Marie nailed it without even looking at the project. You are calling play() on a place that has a trigger that says stop(). The reason it plays the second time is rather complicated and has to do with the default play() behavior when there's a trigger, but the easy thing to do is to add one to your click event timecode.
For instance: Presentation.click currently says:
sym.play(22000);
Just replace it with:
sym.play(22001);
The next easiest thing to do is to change your play call to use the optional "false" parameter to force it to not execute the trigger at 2200.
sym.play(22000, false);
http://www.adobe.com/devnet-docs/edgeanimate/api/current/index.html#symbolinstance
- scroll down to "play" to read more about the API
Hope that helps!

I used to single click to open mail & now I have to double click. I have not changed preferences. Any suggestions?

I have always single clicked to open mail. Now I have to double click. I have not touched preferences or made changes. Any suggestions?

Safari Top Sites: Single click not enough

I don't know if this is a bug or anything else, but it's a bit annoying:
When you open a new tab in Safari and the Top Sites shows up, a single click on a site doesn't get you to the page, it just updates the Top Sites so the blue border is shown around the sites.
This is what it looks like: http://youtu.be/88W_KJAj8Hc
I hope this bug gets fixed soon or anybody has got the solution to this.
Greetings
Silvan

It's not possible to mark as unsolved.
You didn't mention you were doing this in full screen mode in your first post.
Try troubleshooting extensions and third party plug-ins.
From your Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that off if there are any installed. Quit and relaunch Safari to test. If that helped, turn extensions back on then uninstall one a time to test.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
If nothing above helped, try a Safe Mode boot. A Safe Mode boot deletes some system caches thay may help.
Startup your Mac in Safe Mode
A Safe Mode boot takes a longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from your Apple () menu.
Then try Safari TopSites in full screen mode.
BTW, it's not a bug. No problem using TopSites in full screen mode here.

How to detect only single click and not double-click mouse events in Swing?

Hi,
In my application, I want to implement a functionality only for single click. But problem is on double click, first i can see a single click and then double click.
i.e e.getCount() return 1 and then 2 for double click. I want to avoid this situation.
Shouldn't it be just one event with a clickCount of 2? or any alternative solution?
Please let me know how can i stop this.
Thanks in advance..
Cheers
