The single-click challenge

The single-click challenge
Assume you are in the Finder. There are no windows open. You want to create a new window, and to show your most natural place: Home.
I can't think of much else that might be as basic and as trivial. It is something that should be doable with a single click. Not a double-click. Not via a keystroke combination. Doable by a single click at anytime, no matter what app is in the foreground.
This used to be possible in Tiger, just: You had to drag your home folder onto the dock. It would sit there, looking cosy with its little roof and windows, and waiting to be single-clicked on. No matter where and when, swoosh to the dock, click, hey presto.
Try it on Leopard. Your home-on-the-dock has turned into a demented bland smudge. You now have to first sit there and suffer the visual assault of stacks. It is hard to believe that something could combine such blue-gray dreariness with so much kitsch in its interfering action. And if you want your new home window, you have to first click, then either hold, wait, move up carefully, and release, or alternatively release, move to some obscure blob with a swirl and click again.
Maybe one of you can suggest something, something that I'm surely missing. Surely there IS a single-click option without writing a special patch. No?
As for my overall impressions of Leopard: Yes, the graphics are dazzling, thank you. But the loss of countless simple yet vital functionalities, the ubiquitous in-your-face sidebar that devours my screen space and will not go away, the quantum-mechanical nature of what spotlight may or may not choose to find depending on which side of the bed it got out of, and so much more.. these all make me sick as a parrot. Shame on you, Apple. Add visual power, by all means. But you have dumped on reliability from a great height, turned searches into random walks, and you have robbed us of countless past options that let us keep things simple by OUR personal standards, not by yours, if we preferred so to do. Try again, and very very fast, please.

Welles has effectively elaborated on the conditions necessary for John's solution to work. Which actually means that if you have a different preference for your initial folder location, Leopard STILL flunks it totally. So technically the challenge is back on! I'm so glad I didn't mention a prize

Please make the camera available on the single-click lock screen.

It just makes sense. People want the camera readily available. Having it on the double-click lock screen is good. Having it on the single-click lock screen is better.
It's that simple.
Also, double-clicking the home button is hit-or-miss at best. At worst, it just plain *****.
Please put the camera on the single-click lock screen.

Hi Dan,
this forum is for users. If you want to make a suggestion to apple you can write an email at http://www.apple.com/feedback/. In my opinion this settings makes sense since you would have a lot if unwanted pictures while carrying your iphone in your pockets

How to make the DefaultMutableTreeNode response to the single click?

I use the DefaultMutableTreeNode and JTree to construct a Tree but it seems that DefaultMutableTreeNode only response to double click.That means if I double click on the node of the tree if that node has children they will be displayed.but now I want DefaultMutableTreeNode response to single click,how can I do that?

Hi, perhaps I could take a stab at this. I implemented such functionality by simply adding a mouse listener to my tree, and implementing the method 'public void mouseReleased(...)'. You could use the MouseEvent object to get the x,y coordinates of the click (simple so far)and then use:
int selrow=tree.getRowForLocation(me.getX(),me.getY()); //where me is MouseEvent object and tree is the JTree.
selrow>=1 if you have clicked any of the nodes after the root. this could then be used to check and perform the actions/code block you need when user clicks on a node.
Hope this helps....it worked for me to show a popup menu as well as to highlight the selections...by using
tree.setSelectionRow(selrow);
Cheers

Originally when I cliked on a new email in the inbox, it opened immediately. Now I have to double click on it to open. How do I get back to the single click?

It now takes a double click to open an email. How do you get it to open on the first click?

There is no need to open two threads for the same question.

My Trackpad is not doing the single click am using the tap to click

i don't know what happen all of the sudden my comp trackpad click botton stopped working did i disable it?if i did i don't see any option to turn it on again.

Did you go to System Preferences > Trackpad? Check and see if you somehow disabled it. If "tap-to-click" is still checked off, try unchecking and re-checking it, without a re-start first time around. If that fails, then with a re-start between unchecking that box and re-checking that box.
If that fails, then you might need to take it in.

Seems I have lost my "home" button, the single click that takes me to my home page. Does anyone know where it is?

Thats it

# Press Alt+V
# Select Toolbars
# Click on Customize
# You will icons in a dialog box.
# Find the Home Button and simply drag it on your navigation bar.

[q] .cab single-click install works in 1.4.1-rc?

Has anyone tried the single-click install feature with 1.4.1-rc?
I know the docs state it will be available in the final version, but it would
sure make sense to get some feedback on this before they release.
Thanks.

I'm on vacation and can't try this myself.
I'm surprised no one has tried it yet! I think this is
the single most important feature of 1.4.

How to handle both single click and double click from mouse

hey,
I looked in past threads and didn't get a proper answer for capturing both single and double click from the mouse.
in most applications the single click action does not interfere with the double click action, for example in a text editor, single click sets the cursor in between the text, double click marks a word, triple click marks a sentence, they do not bother each other, they all can happen first the single then the double and then the triple, but what if i have a very distinct action for each of the actions, the e.getClickCount() returns every time the number of clicks and if i use
if(e.getClickCount()==1)
    doSingleClick();
if(e.getClickCount()==2)
    doDoubleClick();it will always do first the single click and then the double click, which works fine with the example i gave, but not with what i want to do, so i was thinking to over come this that i will use another thread to run my tasks if dt has past since the last click and by the last click counts to perform the correct action and go to sleep until the next mouse click notify it, what do you think?
run this to get what i mean...
package blah;

                    if(me.getClickCount()==1)
                         System.out.println("Now I will do single click action");

//                    System.out.println("Click count: " + me.getClickCount());
          panel.add(component);

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.

Revert back to single click commands?

While using my iPhone 4 the system behavior changed where I now have to click on the app to select it, then double click to launch it. Same goes for entering in my password to access the phone and entering digits to make a phone. I am also having trouble swiping the screen to move to the next page. This is no longer working. I did not change any settings, the phone just started behaving this way. Any ideas on how to revert back to the single click selection/launch? Any assistant is greatly appreciated. Thank you!

The config will be saved as config.old when you change the mode of the firewall (this goes both ways I believe). As Luis has mentioned it is a major change but if you have ASA's in a failover pair then doing this with little or no down time should be possible.
I would first go about this by taking the current Standby ASA and take a backup of the running configuration on it, and make any required changes to the configuration to suite your needs. Most likely you will not have much need of what is in the system context, but take a backup of it anyway just be on the safe side. Then change it to single mode with the command "mode single". Now copy the configuration into the ASA.
Now, assuming that both ASAs have the same IP addresses assigned to its interfaces, remove the currently active ASA and then connect the ASA that is now in single mode back into the network. You may have to clear the MAC address table on some servers depending on how old they are and how touchy they are.
Do the same for the second ASA and connect it back to the network. Now, if you have kept the failover configuration, the ASAs will setup an Active/Standby failover in single mode and replicate the configuration.
Your down time should only be dependent on how fast you can remove the second ASA and add the first ASA back to the network.
Please remember to rate and select a correct answer

Why does my event structure run a single click when I double-click?

I would like to treat single-clicks differently than double-clicks but it appears that when I double-click an item on a Front Panel control it runs the single-click event once before running the double-click event. I would like the single-click event not to trigger if the user double-clicks.
I am discarding the "Mouse Down?" filter event then using the "Mouse Up" notify event to try to catch the difference between a single-click and double-click.
Should I be doing something different with the timeout event (right now it does nothing)?
Should I stop displaying the event type?
Should I eliminate the 5 msec Wait in the Producer Loop?
Should I use the "Mouse Down" notify event instead of the "Mouse Up" notify event?

JeffOverton wrote:
If you edit the event cases, is the "Lock front panel until the case for this event completes" box checked?
I think this is a key configuration to understand.
The current configuration means that the 'mouse up' event for the first click is triggered. Then immideatly the front panel is locked. The second click needs to wait until the event has finished. So I think unchecking that box might improve the code.
Yes you should remove the 5 ms. wait, it has little purpose. It might even cause this: Click 1(& lock), wait 5 ms, event 1 (&unlock), click2 (no double click anymore).

Where is the Double-click Event in Adobe LiveCycle Designer

Hi Experts:
I was trying to put code into a Double Click event in Adobe LiveCycle Designer, but couldn't find the Event. There is a "Click" event, but that won't do.
Am I missing something here?
Thanks,
Jen

Hi Jen,
I was surprised the double click was missing but I use the following code in the click event, just replace the "[my double click code ]" and "[ my single click code ]" with your single and double click code. This code delays the single click event for 400ms to see if a second click is coming, you might want to play around with the 400ms as you have to balance the responsiveness of a single click with the double click.
if (new Date() - this.date < 400)
    app.clearTimeOut(this.timeout);
    this.date = undefined;
    [my double click code ]
else
    if (xfa.event.fullText !== "singleClick")
        this.timeout = app.setTimeOut("xfa.event.fullText='singleClick';xfa.resolveNode('"+this.somExpression+"' ).execEvent('click');",500);
    else
        [ my single click code ];
this.date = new Date();

Double Click / Single click problem

Recently i have been noticing when i single click, using either my magic mouse or trackpad i end up getting a double click, even when my double click is set to as slow as possible.
Is there anything that can be done to stop this, as this makes many of the menu's in photoshop un usable as well as the dashboard calculator :'(

My Mother-In-Laws computer (iMac 2GHz- Snow Leopard with current updates) is acting this way also. In her case, she had a Logictec wireless mouse hooked up with the receiver in the keyboard. She has noticed the single click as a double click in Mail and another program (can't remember the other). Suggested that she go back to the original apple mouse and see if it still acted the same way. I'm on the computer now and have been able to recreate the problem with the Apple mouse. Her mouse click setting was all the way to "low". Moved the setting to the middle and didn't see much of a difference. Maybe slightly more instances of double-clicks.
I have two other macs(my Mac Pro and another iMac) I use on a regular basis and have not seen this problem. But they are also behind on Snow Leopard OS updates. I'm guessing this is an internal problem Apple will have to fix.
