Window System API 
Package Description

Most parts of NetBeans do not manipulate windows directly, but use special top components.

Redesign documents.

Use Cases

Cover of NetBeans Platform for Beginners book For general overview of the concepts, together with code samples, see chapter 6, of NetBeans Platform for Beginners by Jason Wexbridge and Walter Nyland.

General Usecases
General usecases can be read in the design document created before work on new window system design started.
How to create a '.settings' file for a TopComponent?
Either write it by hand (not that hard if you copy other file and tweak it to match your TC), or start the IDE, instantiate the TC somehow (You have a "Window->Show My TC", right? ), copy the file that gets created in $userdir/config/Windows2Local/Component and cleanup the serialdata section - replace it with proper "<instance class='..." /> tag.
How to make a TopComponentGroup?

Q: I'm trying to make a TopComponentGroup. I've just read http://ui.netbeans.org/docs/ui/ws/ws_spec.html#3.9 I want to make a group that uses the first invocation strategy. That is, I want the group to open/close when I activate a certain subclass of TopComponent. Say, for example, I have a FooTopComponent, and when it's active, I want to open a FooPropertySheetComponent, docked in a mode on the right-hand side. I know I have to:
  1. declare the group in the layer file (Windows2/Groups)
  2. have code for opening the group
  3. have code for closing the group
I think I do #2 in FooTopComponent.componentActivated() and #3 in FooTopComponent.componentDeactivated(). Is that right?

A:Yes it is correct way. You can check simple test module. First you must get TopComponentGroup instance using find method then call TopComponentGroup.open()/close(). Here is the code in your componentDeactivated method:
   protected void componentDeactivated ()
   {
       // close window group containing propsheet, but only if we're
       // selecting a different kind of TC in the same mode
       boolean closeGroup = true;
       Mode curMode = WindowManager.getDefault().findMode(this);
       TopComponent selected = curMode.getSelectedTopComponent();
       if (selected != null && selected instanceof FooTopComponent)
           closeGroup = false;
             if (closeGroup)
       {
           TopComponentGroup group = WindowManager.getDefault().findTopComponentGroup(TC_GROUP);
           if (group != null)
           {
               group.close();
           }
       }
   }

KeepNonPersistentTCInModelWhenClosedExportedPrivate

Client property "KeepNonPersistentTCInModelWhenClosed" of TopComponent controls behavior of winsys when TopComponent with persistence type "Never" or "OnlyOpened" is closed. As some TopComponent wants to keep their position in winsys ie. be able to reopen at the same place and some TopComponent wants to be removed from winsys model. If property is not set nonpersistent TopComponent is removed from model when closed - it is original behavior before fix of issue #101700. If property is set (to Boolean.TRUE) then TopComponent is kept in model. It means that client must explicitly set this client property to get behavior requested by issue #101700.

netbeans.winsys.tc.activate_at_startupExportedPrivate

Name of TopComponent's Boolean client property which instructs the window system to activate the given TopComponent at startup time regardless which TopComponent was active at shutdown time. So it's usuable for welcome screen-like behavior. If more than one TopComponent has this property set to Boolean.TRUE then an arbitrary one will be selected and activated.

TopComponentAllowDockAnywhereExportedPrivate

Name of client property (of Boolean type) which says whether the TopComponent is allowed to be docked anywhere (even crossing view-editor border).

netbeans.winsys.tc.keep_preferred_size_when_slided_inExportedStable

Name of TopComponent's Boolean client property which forces the window system to respect TopComponent's preferred size when it is slided-in from left/right/bottom sliding bar when set to Boolean.TRUE. Otherwise the slided-in TopComponent will fill the entire width/length of the IDE window (the default behavior). This switch is intended for tools/palette windows like e.g. color chooser, tool picker etc.

netbeans.winsys.tc.closing_disabledExportedStable

Name of TopComponent's Boolean client property which removes close button from TopComponent's header and disables its 'Close Window' action when set to Boolean.TRUE.

netbeans.winsys.tc.sliding_disabledExportedStable

Name of TopComponent's Boolean client property which removes 'minimized' button from TopComponent's header and disables its 'Minimize Window' action when set to Boolean.TRUE. TopComponents which are already slided-out and have this property set to Boolean.TRUE will have 'pin' button removed from their header and their 'Minimize Window' action will be disabled.

netbeans.winsys.tc.undocking_disabledExportedStable

Name of TopComponent's Boolean client property which disables TopComponent's 'Undock Window' action when set to Boolean.TRUE. TopComponents which are already floating and have this property set to Boolean.TRUE will have their 'Dock Window' action disabled.

netbeans.winsys.tc.dragging_disabledExportedStable

Name of TopComponent's Boolean client property which disables drag and drop when set to Boolean.TRUE.

netbeans.winsys.tc.maximization_disabledExportedStable

Name of TopComponent's Boolean client property which disables TopComponent maximization by double-clicking its header when set to Boolean.TRUE. TopComponent's 'Maximize Window' action will be also disabled.

netbeans.winsys.tc.draganddrop_copy_disabledExportedStable

Name of TopComponent's Boolean client property which disables 'copy' drag and drop action of a TopComponent when set to Boolean.TRUE.

OpenIDE-Transmodal-ActionExportedFriend

An Action with the property OpenIDE-Transmodal-Action set to Boolean.TRUE should function on all focused components. This includes the Main Window, dialogs, popup menus, etc. Otherwise only the Main Window and TopComponents will receive the keystroke.

NbMainWindow.showCustomBackgroundExportedStable

Name of boolean property in javax.swing.UIManager. When the property value is TRUE then the window system will turn off opacity for most of the main window components - menu bar, toolbars, status bar, sliding bars and the main desktop area component. That means that the main window background will be showing through these components. The property value must be set before the window system loads.

netbeans.windowsExportedPrivate

This property was deleted and has no effect now, as sdi support was dropped and replaced by individual seperate windows. Please don't use, it's useless.

org.netbeans.ui.actions.UI_ACTION_KEY_PRESSExportedFriend

There is a special support for notifying when an action is invoked by the TopComponent's key event handling code. The support is using Logger.getLogger("org.netbeans.ui.actions") and sents a LogRecord with message UI_ACTION_KEY_PRESS, FINER level and paramerters:
  • {0} instance of the KeyStroke
  • {1} toString of the KeyStroke
  • {2} instance of the action
  • {3} class of the action
  • {4} display name of the action
whenever such action is invoked. This message can then be consumed by enhanced UI logger that track what the user is going.

What do other modules need to do to declare a dependency on this one, in addition to or instead of a plain module dependency?
You might use OpenIDE-Module-Requires: org.openide.windows.WindowManager but it is not generally done.
