WindowManager (Window System API)

java.lang.Object
- org.openide.windows.WindowManager

All Implemented Interfaces:

Serializable
```
public abstract class WindowManager
extends Object
implements Serializable
```
Manages window system. Allows the work with window system components, i.e. Modes, TopComponentGroups and provides handling of operations provided over TopComponents.
Important note: Do not provide implementation of this abstract class unless you are window system provider!

  - invokeWhenUIReady
```
public void invokeWhenUIReady(Runnable run)
```
    Provides support for executing a piece of code when UI of the window system is ready. The behaviour is similar to EventQueue.invokeLater(java.lang.Runnable) moreover it is guaranteed that only one Runnable runs at given time. This method can be invoked from any thread.
    The typical usecase is to call this method during startup of NetBeans based application. The default manager then waits till the main window is opened and then executes all the registered methods one by one.
    Usage:
```
  // some initialization method
  public static void init () {
     WindowManager.getDefault().invokeWhenUIReady(new Runnable() {
        public void run() {
           // code to be invoked when system UI is ready
        }
     );
  }
 
```
    Note to WindowManager providers: This method is not abstract for backward compatibility reasons, please override and provide implementation.
    Parameters:
    run - the runnable that executes piece of code when UI of the system is ready
    Since:

    Parameters:
    mode - Mode to get the list of TopComponents from.
    
    Returns:
    Array of TopComponents that are opened in given mode.

  - isEditorMode
```
public boolean isEditorMode(Mode mode)
```
    Check whether the given Mode holds editor windows.
    
    Please note that some TopComponents may be docked into 'editor' modes as well as 'view' modes, see method isTopComponentAllowedToMoveAnywhere().
    
    Parameters:
    mode - Mode to check.
    
    Returns:
    True the Mode contains editor windows.

  - addWindowSystemListener
```
public void addWindowSystemListener(WindowSystemListener listener)
```
    Register window system listener to receive notifications when the window system loads or saves.
    
    Since:
    
    6.43
  - removeWindowSystemListener
```
public void removeWindowSystemListener(WindowSystemListener listener)
```
    Remove window system listener.

  - setRole
```
public void setRole(String roleName)
```
    Switches the window system to a new role (perspective).
    
    A role may customize the default window layout by adding/removing TopComponents, changing window positions and/or sizes etc. Roles are defined in XML layers in folder Window2/Roles. Each role has a unique name corresponding to a sub-folder in Window2/Roles. The content of a role sub-folder has the same syntax and meaning as the default window layout in Windows2 folder. The content of role sub-folder is merged with the defaults in Windows2 folder when the window system loads. User's changes to the window layout are persisted per role. So user's customizations in role A are not propagated to role B and vice versa.
    
    The default implementation of this method in core.windows module does the following:
    1. Hide the main window.
    2. Save the current window layout of the current role.
    3. Load new window layout from the given role.
    4. Show the main window.
    The whole operation may take a few seconds to complete.
    
    Windows that were opened in previous role but are not opened or present in the new role will receive TopComponent.componentClosed() notification.
    
    Note: To keep the main window showing while switching the role, use the following branding: org.netbeans.core.windows.WinSys.Show.Hide.MainWindow.While.Switching.Role=false
    
    Note: Action org.netbeans.core.windows.actions.SwitchRoleKeepDocumentsAction in Actions/Window layer folder can change the role too but it also attempts to keep documents from previous role opened in the new role as well. The new role name is ActionEvent.getActionCommand() argument.
    
    If the window system has been already loaded then the method must be called from EDT thread, otherwise it's safe to set the initial startup role in e.g. ModuleInstall.restored() method.
    Parameters:
    roleName - Name of the new role to switch to or null to switch to the default window layout.

  - isTopComponentFloating
```
public boolean isTopComponentFloating(TopComponent tc)
```
    Checks the floating status of given TopComponent.
    
    Returns:
    True if the given TopComponent is separated from the main window.

  - setTopComponentFloating
```
public void setTopComponentFloating(TopComponent tc,
                           boolean floating)
```
    Floats the given TopComponent or docks it back to the main window.
    
    Parameters:
    tc -
    floating - True to separate the given TopComponent from the main window, false to dock it back to the main window.

  - getRole
```
public String getRole()
```
