UNC paths on Windows

Now the NetBeans IDE supports UNC paths like ""computerName"sharedFolder" . It is possible to install the IDE to UNC like folder and also it is possible to create projects and other resources on UNC paths.

File Associations options panel and Open As... action

A new panel in options dialog which allows to say to NetBeans that files with certain extension should be treated as files with a certain MIME type (see #133773 ). You can add a new extension to the list of modify existing one. If you want to restore default setting for selected extension, you just click the Default button.

In connection with the above change there was also added a new Open As... action. It is enabled only for files which are not recognized by the IDE. User can choose one from supplied MIME types and from now on all files with this extension are treated as of choosen MIME type.

Running some IDE distributions on JRE

Certain IDE distributions (e.g. PHP IDE) don't require Java JDK to run on, JRE is enough.

Plugin Manager now checks OpenIDE-Module-Package-Dependencies of all modules which user selects to be installed. If the user's IDE is running on JRE and the unsatified package dependency might indicate that JDK is required, user is warned about it and the plugin installation is not allowed.

QuickSearch

Quickly search for action or type is now easy. Use Ctrl-I.

UI spec:http://ui.netbeans.org/docs/ui/quicksearch/index.html

Variable based paths in J2SE/J2EE projects

Since NetBeans 6.1 it is possible to control whether JAR/Folder added to project classpath is referenced via absolute or relative path. Now it is also possible to define a global IDE named variable pointing to a folder and use this variable as a base for referring to JARs/Folders.

This feature further simplifies project sharing between users. In scenario where a project depends on JARs for which:

it is not desirable to store them in VCS; and which
can be placed in different locations for different users

a named IDE variable can be used.

The variables are managed via Tools -> Variable menu item:

In above screenshot single variable is defined with these details:

When variable based JAR/Folder is added to project classpath you can see its path starting with variable name (and tooltip showing absolute path):

Variable based JAR/Fodler is added to classpath via standard means of "Add Jar/Folder" button in classpath customizer (or "Add JAR/Folder" action on project's Libraries node in project's view). Custom file chooser is shown with one new option "Use Variable Path":

Just browse for your JAR/Folder and if selected file is under a variable the option gets enabled. Alternatively press "..." button and setup a new variable.

If a user opens project with a variable based path and the variable is not defined in user's IDE then standard broken reference warning is shown to advice user to define variable:

Eclipse project import and synchronization

The Eclipse project import feature facilitates mixed IDE development teams. It allows you to select Eclipse projects from an Eclipse workspace and generate NetBeans projects for them. The generated NetBeans project keeps a link to the original Eclipse project and will update itself after any relevant change: for example, changing the classpath of the Eclipse project. The update is done automatically when the NetBeans project is opened, or can be explicitly requested via a context menu item "Synch with Eclipse" on the project.

This is early preview of the Eclipse import feature which will be fully implemented in Milestone 2. (It supersedes the limited Eclipse import feature available in former NetBeans releases on the update center.) We would appreciate feedback and real-life Eclipse projects for testing; best is to use Issuezilla. (component ide , subcomponent eclipse project import )

Enhanced Java Web Start support

Support for creating applets that can be deployed via Java Web Start was added to NetBeans IDE. Note: the functionality is available in JDK 1.6.0 update 10.

Each application or applet deployed via Java Web Start can specify external resources (usually other JNLP file in internet). Dialog is opened by clicking on 'External Resources' button.

Each applet can have number of properties defined in JNLP file, those properties can be defined in dialog that is opened by clicking 'Applet Parameters'. Also you can set applet dimensions in the dialog.

Platform

Sliding windows support original window sizes

Slided-in windows can keep their preferred size instead of being stretched to the whole height/width of the IDE window.

(see #135318 ).

Possibility to configure some Window System properties for applications based on Platform

Some window system features can be turned off by branding of core.windows module.

TreeTableView replacement introduced

OutlineView is a new replacement for buggy TreeTableView. It supports drag and drop, in-place editing of tree cells, enhanced sorting etc. The data model is fully compatible with TreeTableView.

(see #33281 ).

Opening Options dialog with preselected subcategories

API in options.api module has been changed to allow open Options dialog with preselected subcategory (see #109538 ). In your code you can call OptionsDisplayer.getDefault().open("CategoryID/SubcategoryID"); where CategoryID and SubcategoryID are registration names from layer. For selection a panel under Miscellaneous category use OptionsDisplayer.getDefault().open(OptionsDisplayer.ADVANCED+"/SubcategoryID"); .

Support allowing a user to drop a text into the palette

It is possible to drag and drop any text to the Palette window to create a new code snippet. It works for HTML editor palette only at the moment, more document types will follow soon.

PHP

Features first introduced in Early Access for PHP

The NetBeans IDE Early Access for PHP was released in April at the same time as NetBeans 6.1. Milestone 1 of NetBeans 6.5 now contains all features introduced in this release .

Next, in NB 6.5 M1, PHP features are a part of the "all-in-one" distribution of NetBeans, so they can be used together with all the other NetBeans features. Of course, there is still the slim PHP edition of NetBeans, targeted for PHP development specifically.

See below for more features added in NetBeans 6.5 Milestone 1, that were not present in Early Access. Also, to keep up with the new features added to NetBeans PHP support, make sure to check and bookmark the NetBeans PHP Team Blog .

Database-related code snippets

Generate code to connect to a MySQL database and to display the data in a database table. These snippets are available under the Generate Code action [Alt+Insert], just like in the Java editor.

Find Usages

Available also for PHP development. Right click the item and select "Find Usages" or hit Alt-F7.

Java SE Project Integration

Database

Improved New Connection dialog

Now the dialog for creating a new database connection does not expect you to know the details of the JDBC URL to open a connection. If you want to modify the URL, however, you can do so, just click on the "Show JDBC URL" checkbox. Changes to the URL are reflected in the fields and vice versa.

SQL history dialog

SQL that has been executed is saved to a file in the userdir and available for viewing in a dialog and also SQL can be selected and reinserted in an existing SQL file.

Server Support

GlassFish V3 integration module.

Is now part of the Web & Java EE and Ruby bundles. No need to get the modules from the update center.

Web frameworks (Spring, Hibernate, JSF, JSF CRUD Generator, JPA)

Spring

Improved Java class FQN completion

Code completion is now faster than the earlier version. For efficiency, Java class FQN completion is now a two step process. Most of the times, a user will need only classes defined locally in the project (source classpath). Hence the first CTRL+SPACE will list only the items in the source classpath, as shown below:

If the user wishes to add an item not in the source classpath, he can press CTRL+SPACE again. Also, if the typed prefix does not match any local item, the completion will automatically switch to show all items instead of just local items.

Go to Spring Bean dialog

A Go to Spring Bean dialog is similar to the Go to Type dialog and will allow the user to quickly navigate to a given Spring Bean definition by it's name. The user selects the main menu item Navigate | Go to Spring Bean... or the keyboard short cut Alt + Shift + B to invoke the Go to Spring Bean dialog.

Refactoring support for Java properties

When refactoring Java Bean property getters and setters, the corresponding usages in the Spring XML Configuration files are also modified.

Hibernate (Available via Development Update center for M1)

Reverse Engineering support. With an existing configuration, POJOs and mapping files can be generated using this feature. See Reverse Engineering for more details

HQL query execution support. Execute HQL queries right inside the IDE. Queries can include joins and clauses. See HQL Editor for more details

Refactoring of hibernate mapping files is supported. See Refactoring for more details.

JSF, JSF CRUD Generator

The editor support for both JSF Configuration Files and JSF JSP Pages are both improved. The improved features include: Code Completion, Hyperlink, Refactoring, and Find Usage. More details can be found at Editor Support in JSF Configuration Files and JSP Files .

Code Completion: On top of the generic JSP editing features, the JSP editor for the JSF page file provides additional code completion for Managed Beans and Resource Bundles.

Example	Code Completion UI
Managed Beans
Resource Bundles

Hyperlink: By using the Hyperlink inside the JSF configuration files and JSF JSP Pages, developers can fast navigate from one source to another reference.

JSF Configuration Files Example	File opened

`foo.ManagedBean`	the Java file `ManagedBean.java` under package `foo`
`/Page2.jsp`	the JSF page file `Page2.jsp` under the context root

JSF JSP Pages Example	File opened
`<h:outputText value =" #{ManagedBean .min}" />`	the JSF configuration file on position where the managed bean been defined
`<h:outputText value =" #{ManagedBean.min }" />`	the appropriate Java file on position where the getter for the property been defined

Refactoring Support: The refactoring support processes all files in the list of JSF configuration files. Bean and Java class/method usages are found in bean and alias elements and their subelements, as well as elements in the util namespace.

Example	Refactoring UI
Managed Beans
Folder / Package

Find usages: The JSF support will plug into the Java find usages to show JSF beans definitions which refer to Java elements (classes, methods, fields, properties). The Find Usages action will be available for bean definitions as well, to show beans used by other beans.

Example	Usages UI
Managed Beans

The JSF CRUD Generator now applies default styles.

JPA

In NetBean 6.5, the Entity Classes from Database wizard has one additional panel to allow the user to configure the following mapping options:

Association Fetch: can be default, eager or lazy. By default, it is default, meaning no fetch attribute will be added to the relationship annotations
Collection Type: The collection type used for OneToMany and ManyToMany CMR fields. Can be java.util.Collection, java.util.List or java.util.Set. By default, it is java.util.Collection.
Fully Qualified Database Table Names: if checked, catalog and schema attributes will be added on @Table. By default, it is not checked.
Attributes for Regenerating Database Tables: if checked, nullable (when it is false), length (for String type), precision and scale (for decimal type) will be added on @Column. Unique constraints will be added on @Table if checked. By default, it is not checked.

The panel is at the last step of the wizard. It is optional.

UML

NetBeans Development is migrating UML to the NetBeans Visual Library. The majority of the planned features are now implemented in the release trunk and the Development is focused on stabilizing the code for release. The new UML will be available in M2. Please see UML Current Projects for additional information.

Mobility

Databinding

Mobility Data binding provides a simple and consistent way for applications to present and interact with data in the Visual Designer. It utilizes the Databinding libraries available in Netbeans Mobility. New custom component DataSet which provides data for UI components.

Supported components in Milstone 1:

Debugger

New Multithreaded Debugging Support

This is a summary description for the new Multithreaded Debugging Support that is available in M1 NB 6.5. These bits have been done as a first phase of the overall NB debugger redesign effort, which goal is to significantly improve the debugging workflow and usability.

Debugging Window

In order to improve UI for multithreaded debugging and also willing to reduce the number of debugger views, a new (unifying) debugger view is introduced. This view (referred as Debugging View) integrates current Sessions, Threads and Call Stack views being displayed in the Explorer group by default.

From the technical perspective, the Debug view is organized as (in general) a list of sessions, having each session as a list of threads, each suspended thread than expandable to its call stack and more. Debug view is customizable via context options only showing typically needed info by default. With the 'Suspend Table' switched on, any thread can be resumed/suspended by one click on the dedicated button.

If there is the debugger counter displayed in the editor and another thread encounters a breakpoint, the current thread will not be automatically switched. Instead, a non-modal panel is displayed in the bottom of Debugging view informing that there are new breakpoint hits waiting; there is also a drop-down button switching the debugger to the next (or selected) breakpoint hit. Having this non-modal notification, users are allowed to finish their debugging of current thread (e.g. expression evaluation) and switch to next breakpoint hit when it fits to the workflow.

Current Thread Chooser

When doing a multithreaded debugging, it is often needed to quickly switch between particular threads; e.g. when doing a stepping sequence in two threads alternately. For such purpose we introduce a new action--Current Thread Chooser (CTRL+8). In fact, it is an analogy to application switching common in OS environment. With this feature, it is really straightforward to revisit any thread for debugging or switch to a particular thread for the first time.

'Other Thread(s) Suspended Here' Gutter Navigation

Anytime the debugger displays the thread icon in the editor gutter, the user is informed that there is/are one or more suspended non-current thread(s) at this line. The list of these threads can be seen in the icon tooltip, and it is also possible to switch debugging to any of these threads via the context menu. Strictly speeking, it is the Source->Threads navigation available in the editor gutter.

Deadlock Detection

The debugger automatically searches for deadlock among all suspended threads. When a deadlock is detected, a non-modal notification is displayed having emphasized involved threads. Detailed monitor info is also available displayed in dedicated monitor nodes.

New Threading Model

In order to improve multithreaded debugging, we decided to change the way how debugger manages debuggee threads. The main issue related to current model (NB 6.1 and older) is likely the fact that any step resumes all threads regardless there are threads intentionally suspended by the user or not. This can be limiting e.g. in case of debugging race conditions or deadlock issues. The natural solution to this problem is to resume only the current thread leaving other threads suspended if they are (may have happened via breakpoints or Suspend action). Obviously, this change needs the default breakpoint to suspend only the breakpoint thread, otherwise stepping could lead to so-called Deadlock Caused by Debugger.

Current Model Summary (NB 6.1 and older):

Default breakpoint suspends all threads.
Step resumes all threads when invoked and suspends all threads when completed regardless there are threads intentionally suspended or not.
Evaluation is done only resuming the current thread (by default), which may easily lead to 'deadlock caused by debugger' in current model.
'Step interrupted by a breakpoint' issue exists with default breakpoint.

New Model Summary:

Default breakpoint only suspends breakpoint thread.
Step only resumes current thread when invoked and suspends current thread when completed.
Evaluation is done resuming the current thread (other threads unsuspended by default breakpoint or step). No deadlock caused by debugger might happen as far as no thread is explicitly suspended by the user (via suspend action or some breakpoint).
'Step interrupted by a breakpoint' issue does not exist with default breakpoint. (Except the stepping thread itself encounters a breakpoint.)

GUI Builder

ButtonGroup visualization

When you select a ButtonGroup or some component in a ButtonGroup then the GUI builder shows you which components belong into this group.

Preview in Nimbus look and feel

If you use JDK 6 Update 10 then you can preview your form in the new Nimbus look and feel. We have made this preview more reliable and accurate (within the limits of javax.swing.UIManager design). Besides the design preview you can also set the Nimbus look and feel for runtime - this is easily possible for Desktop Java Application projects in the Project Properties window (go to the Desktop App panel).

TreeModel editor

New TreeModel property editor allows you to prototype your JTree easily.

ListModel and ComboBoxModel usability enhancements

We rewrote property editors for ListModel and ComboBoxModel. It is much easier to use them by now.

Web Services

RESTful services from database

A new wizard allows for the creation of RESTful, JSR311-based services directly from database tables. This facility is in addition to the wizard that creates services from JPA entities.

Consuming popular SaaS services in Php

Web Services nodes in the Services tab of Netbeans 6.5 support Drag-n-drop to Php files as shown below.

C/C++

Code completion accuracy

Code completion accuracy is much improved in milestone 1 compared to NetBeans 6.1. There are very few known cases where an incorrect choice is presented. So the known "inaccuracy rate" is nearly 0. There are known situations where valid choices are not presented to the user. For a range of mid to large scale applications those cases (where valid choices are not shown) is under 5%. Work to further improve accuracy is ongoing.

Call Graph

Show all callers/callees of the selected function.

Direct call graph:

Reverse call graph:

Error highlighting and more types of semantic highlighting

C/C++ editors highlights basic errors. Semantic highlighting for typedefs, class fields and function names was added.

CONAN — Mon, 23 Jun 2008 14:37:00 GMT

Eclipse用户��L��在NetBeans炫耀Eclipse是多么的漂亮�Q�尤其会说NetBeans的字体丑陋，NetBeans的字体太��，�~�辑器里的字体不好看�Q�字体边楞有锯�ɽ{�等。坦白的��_��q�也是我刚从Eclipse转到NetBeans的第一印象。其实由于NetBeans使用Swing构徏界面�Q�这使得它缺省的使用Swing的缺省配�|�，��其是中文，��更不敢恭维。其实NetBeans提供了强大的配置工具�Q�完全可以将NetBeans配置的很漂亮。下面我��׃��Windows上的NetBeans安装��Z��Q�说说如何配�|�字体�?/p>

1.NetBeans界面上的普通字体大��，可以通过配置NetBeans安装目录下netbeans.conf启动文�g来实玎ͼ��q�个文�g�?lt;NetBeans>/etc目录下。缺省的NetBeans在��用Swing的缺省字体，大小�?1�Q�稍�E�嫌��，如果要改�?2�Q�可以将文�g中的下面一行：

netbeans_default_options="-J-Xms32m -J-Xmx256m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true"

�Ҏ��

netbeans_default_options="-J-Xms32m -J-Xmx256m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true --fontsize 12"

另外�Q�也可以通过讄��Swing的一个控制字体的�pȝ��属性swing.useSystemFontSetting来实玎ͼ�

netbeans_default_options="-J-Dswing.useSystemFontSettings=false -J-Xms32m -J-Xmx256m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true"

2.�~�辑器的字体可以通过选项讄��来实玎ͼ�具体是Tools->Options->Fonts & Colors�Q�这儿可以设�|�包含字体、前后背景等讄��。刚转到NetBeans�Ӟ��我就按照Eclipse和VS2003刚设�|�了一套设�|�，讄��好了之后的NetBeans特别漂亮�Q�一炚w��不输�l�Eclipse�?/p>

3.字体锯��问题�Q�解册��个问题，首先你要使用Java6。Java6支持LCD和反走样(anti-alias)字体�Q�安装Java6后，修改etc/netbeans.conf让NetBeans使用Java6。需要注意的是在Windows下需要明��打开操作�pȝ��的字体边�~��^滑设�|�后�Q�才起作用。设�|�方法是�Q�右键点��L��面，选择外观->效果->使用下列方式使字体的边缘�q�x��->清晰�Q�然后启动NetBeans��可以了�?/p>

另外�Q�我个�h觉得NetBeans�~�省的工��h��按钮太大�Q�如果你和我有同��h��觉，可以右键点击工具栏，从下拉菜单中选择Small Toolbar Icons�?/p>

你将�~�省字体改�ؓDialogInput 12��可以了�?/p>

NetBeans使用心得二：内存和垃圾收集机刉��|?/p>

NetBeans的缺省的内存配置偏低�Q�只�?28M�Q�实际上Eclipse的缺省配�|��ؓ256M�Q�对于NetBeans�q�样拥有如此之多的功能，却才使用128M是不太合适的。曾�l�在别�h的博客上看到�Q�最佳的内存配置应该为物理内存的1/3�Q�如果小于这个��|��NetBeans��难以发挥全效，如果大于�q�个值就会造成操作�pȝ��内存抖动。就NetBeans5.5来说�Q�官方网站上规定的最��内存是512M�Q�推荐内�?G�Q�这一点和其他Java IDE一��P��比如Eclipse官方规定的最��内存居然是1G。这让我不得不叹息我们的电脑实在太落后了。我安��的工作机�?56M�Q�后来买�?12M��M��去，��d��?68M�Q�因此按�?/3原则�Q�我把NetBeans讄��?56M。如何设�|�这个值呢�Q�同前文一栯��讄��启动文�g /etc/netbeans.conf�Q�打开启动文�g�Q�将netbeans_default_options一行中�?J-Xmx选项讄��?56M��可以了�Q�如下：

netbeans_default_options=="-J-Xms32m -J-Xmx256m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true"

使用NetBeans的缺省配�|�，在长旉��的运行后�Q�往往会突焉��僵住了，没有响应�Q�这是因为JVM�~�省的垃圾收集机制不使用增量式�ƈ行收集，而是隔断旉��后，�{�内存垃圄��累到一定程度，完全锁定甚至暂停虚拟机，�q�行垃圾攉��。可以将�q�种垃圾攉��机制�Ҏ��增量式�ƈ行收集，避免�q�种僉|��。同��h��改动netbeans_default_options�Q�在行后加上�Q?/p>

netbeans_default_options=="-J-Xms32m -J-Xmx256m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled"

�ȝ��来说�Q�如果你懒得惌��些，采用下面的配�|�比较不错：

netbeans_default_options="-J-Xms32m -J-Xmx256m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled --fontsize 12"

netbeans_default_options=="-J-Xms32m -J-Xmx256m0.....

J-Xms32m �{�于J-Xmx256m�Ӟ��q�行比较��畅

NetBeans使用心得三：保存配置和改变JDK

NetBeans升��太快�Q�经帔R��要下载新的版本安装，但一重新安装原来的辛辛苦苦的配置好了的东襉K��没有了。另外需要��用不同的JDK�Q�但是重新卸载和安装netbeans又比较麻烦。如何解册��个问题？

原来netbeans��用��L��配置攑֜�用户目录下的.netbeans目录中，在Windows下，用户目录是：

C:\Documents and Settings\

��该目录备䆾保存�Q�可以避免重新配�|�的�ȝ��Q�安装新的NetBeans之后�Q�将.netbeans中对应版本的配置拯��到目标版本的目录��就可以了。比如我保存了NetBeans5.0的配�|�，现在安装�?.5�Q�可以将原来.netbeans/5.0目录下的内容�Q�覆�?netbeans/5.5下的内容�Q�你原来配置的内容包含当前workspace的状态就都�{�U�过��M��?/p>

NetBeans使用心得四：Java�q�_��、NetBeans�q�_��、类库配�|�管�?/p>

NetBeans��目通常来说要针�Ҏ��个Java版本�Q�NetBeans插�g开发需要以来某个NetBeans�q�_��Q�这些项目如果要使用�W�三方类库，都需要引用这些类库。NetBeans中提供了所谓Java�q�行时��^台、NetBeans�q�_��以及�c�d��的配�|�管理。下面介�l�一下如何配�|�和��理�q�些�q�_��及类库：

1.Java�q�_��理�Q�Tools->Java Platform Manager�Q�缺省的有一个JDK的��^収ͼ�如果需要添加其他版本的JDK�Q�可以选择按钮Add Platform...�Q��ƈ在右边的Classes, Sources和Javadoc选择需要添加的�c�R��再选择Add Platform�q�个按钮�Ӟ��NetBeans会询问你JDK根目录，当找到�ƈ且选中�q�个目录�Q�NetBeans会自动将Classes,Sources和Javadoc内容填好。一般如果有Sources了，可以不必选Javadoc�Q�NetBeans会根据Sources自动生成Javadoc以便引用。Classes是用来编译和�q�行以及代码辅助使用的，Sources可以用于调试�E�序时跟�t�代码，而Javadoc会被NetBeans��d��索引到帮助系�l?Help->Javadoc references)�Q�以及代码辅助中昄��帮助。可以肯定的说这样配�|�要比Eclipse方便的多�?/p>

2.和Java�q�_��理�怼��Q�NetBeans�q�_��配置大体遵��@上面步骤�Q�选择Tools->NetBeans Platform Manager�Q�然后的�q�程��和Java�q�_��配置一栗��?/p>

3.和Java�q�_��和NetBeans�q�_��配置�c�M��Q�选择Tools->Library Manager配置�c�d��?/p>

配置好的Java�q�行时��^収ͼ�NetBeans�q�_��以及�c�d��Q�可以通过右键选择��目的属性，在Library一栏，选择Java�q�_��、NetBeans�q�_��以及��d��和删除第三方�c�d��。或者展开��目树，在Libraries节点右键点击�Q�选择New Library或者New Module Dependency�?/p>

NetBeans使用心得五：热键配置、模块管理及其他配置

刚从其他IDE转到NetBeans后，有个不顺手的地方��是热键差别较大�Q�非常常用的主要是代码辅助，在Eclipse是Ctrl+/�Q�而这儿��用的是Ctrl+Space�Q�很不幸的是大部分汉字输入法已经占用了这个热键。幸�q�的是NetBeans提供了修改热键的配置面板Tools->Options->Keymap。另外最新版本的NetBeans5.5�q�提供了Eclipse和Emacs的热键映��，�q�对于从eclipse和Emacs转过来的人来说无疑是天大的好消息�Q�你不用在适应新的热键�Q�只要在�q�儿选择Eclipse或者Emacs��可以了�?/p>

另外你也可以��d��新的热键�Q�比如，我就��d��了一个用于关闭工�E�的热键�Q�热键配�|�中�Q�选择File->Close Project�Q�然后选择Add...按钮�Q�选择Ctrl+Shift+Backspace�Q�你��定义关闭工�E�的热键为Ctrl+Shift+Backspace�?/p>

NetBeans的模块管理负责各�U�插件的更新、下载、安装、卸载等。工具位于Tools->Module Manager和Update Center�Q�这儿你可以很简单根据向导的提示更新、下载、安装以及卸载各�U�插件�?/p>

其他常见配置都能在Tools->Options扑ֈ��Q�包括：

1.General->View Java Packages as List/Tree�Q�让你选择树或者列表的方式�l�织�c�d��?/p>

2.General->Web Browser配置�~�省的浏览器�?/p>

3.General->Proxy配置Web代理�Q�主要用于更新管理器�?/p>

4.General->Auto Update配置自动更新的方式以及频率�?/p>

5.General->Editor->General->Code Folding配置代码折叠选项�?/p>

6.General->Code Completion配置辅助代码选项�Q�是否自动弹出、自动插入单独选项、大��写敏感、是否显�C�弃用代码�?/p>

7.General->Indention配置代码�~�进选项�?/p>

8.General->Code Templates->定义各种快捷模式的模�?/p>

9.General->Macros配置宏变量�?/p>

另外一些杂��可以在Miscellaneous和Advanced选项扑ֈ�。常见的抱怨是辅助代码��Z��弹出那么慢，错误�U�正��Z��出现那么慢，�q�且被认为是NetBeans慢的表现�Q�实际这些都是可以配�|�的�Q��ƈ不是NetBeans造成的，�q�些配置�~�省的�g�q�时间太长，�l�用户造成NetBeans速度很慢地错觉。这些设�|�在�Q?/p>

Tools->Options->Advanced Options->Editing->Editor Settings->Java Editor->Delay of Completion Window Auto Popup

Tools->Options->Advanced Options->Editing->Java Sources->Automatic Parsing Delay

最后，如果你发现有些不想你预料的NetBeans行�ؓ�Q�千万不要马上抱怨NetBeans不能�q�个�Q�不能那个，很可能这又是一个不�W�合你以前习惯的地方�Q�在配置面板找一找，也许��p��扑ֈ�你要的行为配�|��?/p>

netbeans也有一个类似的快捷键：Ctrl + \
