NetBeans has moved in the direction of document-centricness, but the UI is clearly designed (or evolved) from MDI (anathema to mac users) and reflects an different approach than would lend itself on the Mac. Probably if NetBeans were originally designed for OS-X, the following things would be true: There would be no main window or toolbars. Just got a brand new mac. However when I try to install netbeans 7.0.1, I get to the part of the installation where it wants me to select a destination to install. But it says 'Netbeans 7.0.1 cannot be installed on this disk. This software can be installed and work only with Java 6.' I have installed the new 10.7 JDK from apples developer.

NetBeans on OS-X
To platform-specific code or not
The obvious stuff
Subtler but nice to have changes

NetBeans does run on OS-X, as do other Java applications. But there are a number of ways in which it does not meet the expectations of macintosh users. We will explore the problems and potential solutions, starting with those which are glaring but requiring the least work, and moving into greater detail.

This document is a preliminary survey of areas known to be problematic in NetBeans on OS-X. Difficulty is rated on an ad-hoc scale from 1 to ten - these are off-the-cuff estimates trying to take into account as much as I know about the problems involved as possible. Feedback is welcomed - I am new to the Mac, so no doubt there are both some omissions and errors.

As much as I am able, I will try to take the perspective of an OS-X user in terms of the problems and solutions discussed here. Some will be clearly beyond the scope of what we should do, but it is helpful to review all of the options when prioritizing them.

The status notes 'not started' vs. 'not planned' should at this time be considered recommendations - those that are not started are ones I believe we could and should do; those marked not planned are more questionable or more far-reaching changes.

NetBeans is by definition, a Java application - write once, run anywhere. But, particularly with regard to the differences between the Macintosh UI and other platforms, providing an optimal user experience requires paying at least some attention to the expectations of users on a given platform.

While the number of NetBeans users on OS-X is a small (but growing) percentage, if we are to support a platform well, that means doing the work to create a good user experience. It is my opinion that, while we shouldn't go to the extreme of, say, providing an alternate Window System based on Java-Cocoa, we owe it to our users to do what it takes to make NetBeans feel like a natural part of their desktop. After all, if we don't, they'll simply use a competing IDE.

The first items to mention are things that stick out like sore thumbs. Many of them do not require heroic efforts to fix.

  1. Does not use the screen menu bar — Mac apps use a single menu shared between all frames, displayed by the OS at the top of the screen. NetBeans displays its own menu in its main window. This can be fixed using a line switch, but there are currently problems with context sensitive actions not appearing enabled or disabled as they should be.

    Solution: Locate and fix the menu enablement problems, and set the system property to use the system menu bar on startup.

    Complications: None, other than diagnosing what's wrong with our menus - possibly could be rolled into other menu fixes mentioned below.

    Difficulty: 3

    Status: Not started Logitech hub software update.

    Issuezilla: pending

  2. Solution: Write Aqua-friendly UI delegates for custom window system components.

    Complications: Best ways to do Aqua friendly UIs, access to Aqua classes.

    Difficulty: 2

    Status: Provisionally solved

    Issuezilla: pending

  3. Look and feel — NetBeans needs to default to Aqua look and feel. This has already been provisionally changed, and it remains to be seen if there are significant problems that should cause this change to be rolled back. Solution: Make sure NetBeans works properly with Aqua look and feel, provides UI delegates for custom components that fit well in Aqua.


    The above screenshot does not perfectly match the development trunk; it uses the brushed metal look, which, while attractive, causes problems in dialogs, and contains the in progress implementation of finder-style toolbars, which is not in the trunk, and should not be used until after icon redesign. There is a different toolbar UI which is also Aqua friendly which is in the trunk and should ship with 3.6.

    Complications: Access to Apple L&F classes, graphic elements (gradients, etc.) - we should minimize the amount of code that might need to be modified as Aqua evolves.

    Difficulty: 5

    Status: Provisional OS-X delegates pending review

    Issuezilla: pending

The issues below would help NetBeans feel more natural on OS-X, but are non-critical.

  1. Help integration — Even Java apps on OS-X are encouraged to use the operating system's help viewer. We use JavaHelp in our own help window.

    Solution: The OS-X help browser uses HTML; it needs to be investigated how well it could work with JavaHelp content. We might be lucky and the integration could be fairly easy. It probably wouldn't be easy.

    Complications: Interprocess communication, help file format compatibility.

    Difficulty: 8

    Status: Not planned

    Issuezilla: pending

  2. Note in the screenshot above the lack of complexity of the icons (good heavens, they're monochrome!), and how few there are.


    We have an implementation of Finder-style toolbars that could be put in place now, but it tends to emphasize just how badly our icons fit on the desktop more than the current UI. You can see it in the 12-30 development build screenshot above.

    Solution: Reconsider the use of toolbars in general in NetBeans; either revamp them across the board, or offer a smaller subset via defaulting some to hidden if os os-x - this is easy to do - modules like the External Browser module already do similar things to offer per-platform configurations.

    Complications: This needs to be approached by someone willing to slay sacred cows.

    Difficulty: 2

Shortcuts on Mac OS X

Apple Download

The IDE has a default set of keyboard shortcuts that you can use to invoke functions. In some cases, the default IDE shortcuts can conflict with default Mac OS shortcuts. In particular, some function keys used by the Mac OS are known to conflict with some default IDE shortcuts. If you find that some keyboard shortcuts are not behaving as expected, you can modify the shortcut for a particular IDE function by choosing NetBeans > Preferences (Cmd-,) from the main menu and clicking Keyboard in the Options window. You can modify the default Mac OS shortcut by opening System Preferences and clicking Keyboard & Mouse. For more, see the Apple Help topic Using function keys on portable computers.

For a list of NetBeans' Source Editor keyboard equivalents on Mac OS X, see the following table:

Scrolling and Selecting
Cmd-[Moves the insertion point to the highlighted matching bracket. Note that this shortcut only works when the insertion point is located immediately after the opening bracket.
Cmd-Shift-[Selects the block between a pair of brackets. Note that this shortcut only works when the insertion point is located immediately after either the opening or closing bracket.
Ctrl-GJumps to any specified line.
Cmd-ASelects all text in the file.

Modifying Text
Cmd-Shift-JOpens the Internationalize dialog box that you can use to insert an localized string at the insertion point.

Code Folding
Cmd-Minus (-)Collapses the block of code in which the insertion point is currently located.
Cmd-Plus (+)Expands the block of code which is adjacent to the insertion point.
Cmd-Shift-Minus (-)Collapses all blocks of code in the current file.
Cmd-Shift-Plus (+)Expands all blocks of code in the current file.

Recording Macros
Cmd-J then SInitiates the recording of key sequences for a macro.
Cmd-J then EStops the recording of key sequence for a macro and opens the Recorded Macro dialog enabling you to name the new macro.

  • To emulate right mouse click behavior.

    Use Ctrl-click by pressing and holding the Control button while clicking. Also see issue #32463 regarding right-click emulation on multiple files.

  • To specify which JDK to run NetBeans on.

    Use the --jdkhome <path> option when starting NetBeans. <path> is the root of the JDK installation. The NetBeans installer looks for suitable JDK installations available on user's system and allows you to select the one you want to run NetBeans on. However, the setting may become obsolete when the user installs a new JDK later, or may be inconvenient if you want to run the IDE with another JDK. That's where the --jdkhome switch comes in handy.

    Note: If you want to set the <path> option permanently, you can do so in the netbeans.conf file as described below.

  • To make custom startup parameters permanent.

    If you want NetBeans to always start with specific options such as --userdir, --jdkhome, --fontsize, etc., so that you don't have to type them on the command line at every launch, the most convenient way is to add your custom options directly to the NetBeans configuration (netbeans.conf) file.

    To do this, Control-click the NetBeans application icon and choose Show Package Contents from the contextual menu. In the Finder window that appears, navigate to the Contents/Resources/NetBeans/etc/ directory, Control-click netbeans.conf, choose Open With from the contextual menu, and select your preferred text editor. Then add the custom parameters you wish to use and save your changes.

    The netbeans.conf file can include the following entries:

    • netbeans_default_userdir: the default location and name of the userdir. Note that this entry is only valid in the global configuration file. It cannot be redefined in the local netbeans.conf file, because the launcher already needs to know the location of the userdir when the local netbeans.conf file is being processed.
    • netbeans_default_options: any parameters passed to NetBeans or the JVM such as memory configuration parameters, debugging options, --fontsize, various experimental switches, etc.
    • netbeans_jdkhome: the default location of the JDK to run NetBeans on. Note that this can be overridden with the --jdkhome switch.
