&gt; In Netbeans(Windows), Go to &quot;Tools &gt; Options &gt; Miscellaneous/Files &quot;, You will
&gt; find an option called &quot;Enable auto-scanning of sources&quot;.

In case if you want to **manually refresh** (scan) your sources. Then right click the folder in Netbeans Projects window (or any explorere window like Favourites, Files, etc.,) you will find the option called &#39;Refresh Folder&#39;. 

*Note* : This option will be enabled only after you disabled the auto-scanning options. 

On Mac go to menu:
NetBeans/Preferences/Miscellaneous/Files and uncheck ❑ Enable auto-scanning of sources

Works for NetBeans version 8.0.2, MacOs 10.10.2 Yosemite

I&#39;m using MAC Netbeans 8.1 and I dont have `NetBeans/Preferences/Miscellaneous/Files` Can someone help please? `checking external changes` is using all CPU

I dont have `Preferences` in my main menu

PS: I found my solution; I just mention it for others who run into the same issue ; just use this short key to open `Cmd-,` to open the menu: `NetBeans/Preferences/Miscellaneous/Files`

I&#39;ve written a few GUI&#39;s using Swing and I know about MVC, but I never found a good way to really organize my code somehow. What I am looking for is something like the folder structure that maven introduces for each new project. Another example is rails, where MVC is introduced through the folder structure automatically. Is there something similar for Swing?

It would also be nice to see a book that describes the development of a larger Swing Application. All I find are books about design-guidelines where design refers to the look of the application. Other Swing books (like O&#39;Reilly) describe in detail all the swing components, but where is any information about the big picture?

Are there any good examples of a swing gui, where you&#39;d say &quot;That&#39;s how you organize code/folders/packages for swing!&quot;?

EDIT: I found the following site http://www.ibm.com/developerworks/java/tutorials/j-springswing/section7.html which describes the usage of spring while creating a GUI. It is a quite old example and it doesn&#39;t answer my question, but it is a step into the right direction. It also mentions Spring RCP, but I&#39;m not sure if it could be the solution.

EDIT2: I still didn&#39;t find any better answers. Does anybody know an example for a ideally structured Swing GUI which is Open Source? Does anybody know a book, which describes it? And if not for Swing, then maybe for GUI&#39;s in general?

I&#39;m using the generic CreateView like:

    #urls.py

    from django.conf.urls.defaults import *
    from django.views.generic import CreateView
    from content.models import myModel

    urlpatterns = patterns(&#39;myApp.views&#39;,
        (r&#39;myCreate/$&#39;, CreateView.as_view(model=myModel)),
    )

With a mymodel_form.html template like:

    &lt;form method=&quot;post&quot; action=&quot;&quot;&gt;
    {% csrf_token %}
      {{ form.as_p }}
      &lt;input type=&quot;submit&quot; value=&quot;Submit&quot; /&gt;
    &lt;/form&gt;

When I submit my form, the new object is created but I get the error

&gt; ImproperlyConfigured at ...
&gt; 
&gt; No URL to
&gt; redirect to.  Either provide a url or
&gt; define a get_absolute_url method on
&gt; the Model.

How can I specify the url to redirect on success ?

I want to do something like this in Java but I don&#39;t know the way:

then object 2 responds to that event by saying &quot;hello&quot;.

All I am trying to do is to get the current class name, and java appends a useless non-sense **$1** to the end of my class name. How can I get rid of it and only return the actual class name?

This is a small issue, as I could easily whip up a pair class to do the job.  I don&#39;t really want to do this though, and I feel like there should be some simple, built-in, java-like way of returning two values.  What do you guys is the best, simplest way of doing this?  Arrays?  Some other data structure?

Let&#39;s say I want this query to be a valid string in Java. Do I have to convert it to escape all double quotes with a trailing slash in front?

    e.g.  = &quot;CREATE TABLE \&quot;users&quot;\

Or is there a faster way to make this whole query a valid string at once? I thought you could use single quotes around the whole string to do that but that doesn&#39;t work either.

In Netbeans I want to be able too return back to my previous position after selecting `Go to Declaration` (`ctrl + click` on variable). Similar to the option in Microsoft Visual Studio .Net IDE when I click (`ctrl + -`) - it will return to the previous position I was in.

Is it possible, when you mouse hover on method/class so you can see Javadoc in NetBeans 7?

I want similar to Eclipse, when you just mouse hover on `String` and you can read Java API documentation about it.

Maybe there is some hot key for that...

How to see Javadoc documentation on mouse hover in NetBeans?

I have the older NetBeans 6.7, NetBeans 6.9, and NetBeans 7.0, which used to run on jdk1.6.0_21 and jdk1.6.0_25. Now I&#39;ve removed those JDKs and only have jdk1.6.0_26 and jdk1.7.0 left, but I still want to keep the older versions of NetBeans, but now when I run them, I get this message:

&gt; &quot;Cannot locate java installation in specified jdkhome C:\Program Files (x86)\Java\jdk1.6.0_25 \
&gt; Do you want to try to use default version?&quot;

I tried to find where it&#39;s looking for the &quot;jdk1.6.0_25&quot;, and updated a few configuration files in &quot;C:\Program Files (x86)\NetBeans 6.7&quot; and &quot;C:\Users\USER\.nbi\registry.xml&quot;, and yet the message keeps coming. Where and what do I need to change to point it to `C:\Program Files (x86)\Java\jdk1.6.0_26`?




How can I set the JDK NetBeans runs on?

I am developing a front end of a web app using NetBeans IDE 7.0.1. Recently I had a very nasty bug, which I finally fixed.

Say I have code

    var element = &#39;&lt;input size=&quot;3&quot; id=&quot;foo&quot; name=&quot;elements[foo][0]&quot; /&gt;&#39;;
    $(&#39;#bar&#39;).append(element);

I noticed that something gone wrong when I saw that `size` attribute doesn&#39;t work in Chrome (didn&#39;t checked in other browsers). When I opened that element in Inspector, it was interpreted as something like

    &lt;input id=&quot;&amp;quot;3&amp;quot;&quot; name=&quot;&amp;quot;elements[foo][0]&amp;quot;&quot; 
        size=&quot;&amp;quot;foo&amp;quot;&quot; /&gt;

Which was rather strange. After manually retyping the `element` string character-in-character, the bug was gone. When I undo&#39;ed that change I noticed that Netbeans alerted me about some Unicode characters in my old code. It was `\u200b` - a zero width spaces after each &#39;=&#39;, between &#39;][&#39; and in the end of the string. So the string appeared normal because zero width spaces wasn&#39;t displayed, but after escaping them my string was

    &#39;&lt;input size=\u200b&quot;3&quot; id=\u200b&quot;foo&quot; name=\u200b&quot;elements[foo]\u200b[0]&quot; /&gt;\u200b&#39;

Now where the hell did I get them?

I&#39;m not sure where did I copied the code of `element` from, but it&#39;s definitely one of the following:

 - Other pane of Netbeans Editor with HTML template file;
 - Google Chrome Inspector, &#39;Copy as HTML&#39; action;
 - Google Chrome source view page (very doubtfully).

But I can&#39;t reproduce the bug with neither of that.

I use Netbeans 7.0.1 and Google Chrome 13.0 under Windows 7. No keyboard switchers or anything like it is running. Also I&#39;m using Git for version control, but I didn&#39;t pulled that code, so it is very unlikely that Git is to blame. It can&#39;t be a stupid joke of my colleagues, because they are quite well-mannered.

Any suggestions who messed up my code?

I am unsure of how to code popup message box in my methods.

    public String verify(){
        String result = &quot;failed&quot;;
        int authcode = staffBean.getVerifyCodeByName(getLoginUserName());
       
        if (code == authcode){       
            result =&quot;success&quot;;
        }    
        else{ //statement to popup an error message box
    
        }
        return result;
    }

I have tried to use `JOptionPane` in my method but it does not work:

    String st = &quot;Welcome&quot;;
    JOptionPane.showMessageDialog(null, st);
