## Description

The main file is responsible for launching Cinnamon as well as creating its components. The C part of cinnamon calls the `start`() function, which then initializes all of cinnamon. Most components of Cinnamon can be accessed through main.

Determines whether the window actor belongs to a specific workspace

#### Parameters

win | window actor |
workspaceIndex | index of workspace |

#### Returns

whether the window is on the workspace

### getWindowActorsForWorkspace ()

    array
    getWindowActorsForWorkspace (int   workspaceIndex);

Gets a list of actors on a workspace

### pushModal ()

    boolean
    pushModal (Clutter.Actor       actor,
               int                 timestamp,
               Meta.ModalOptions   options);

Ensure we are in a mode where all keyboard and mouse input goes to the stage, and focus `actor`. Multiple calls to this function act in a stacking fashion; the effect will be undone when an equal number of popModal() invocations have been made.

Next, record the current Clutter keyboard focus on a stack. If the modal stack returns to this actor, reset the focus to the actor which was focused at the time pushModal() was invoked.

`timestamp` is optionally used to associate the call with a specific user initiated event. If not provided then the value of global.get_current_time() is assumed.

#### Parameters

actor | actor which will be given keyboard focus |
timestamp | optional timestamp |
options | (optional) flags to indicate that the pointer is alrady grabbed |

#### Returns

true iff we successfully acquired a grab or already had one

### popModal ()

    popModal (Clutter.Actor   actor,
              int             timestamp);

Reverse the effect of pushModal(). If this invocation is undoing the topmost invocation, then the focus will be restored to the previous focus at the time when pushModal() was invoked.

`timestamp` is optionally used to associate the call with a specific user initiated event. If not provided then the value of global.get_current_time() is assumed.

#### Parameters

actor | actor passed to original invocation of pushModal(). |
timestamp | optional timestamp |

### createLookingGlass ()

    LookingGlass.Melange
    createLookingGlass ();

Obtains the looking glass object. Create if it does not exist

#### Returns

looking glass object

### getRunDialog ()

    RunDialog.RunDialog
    getRunDialog ();

Obtains the run dialog object. Create if it does not exist

#### Returns

run dialog object

### activateWindow ()

    activateWindow (Meta.Window   window,
                    int           time,
                    int           workspaceNum);

Activates `window`, switching to its workspace first if necessary, and switching out of the overview if it's currently active

#### Parameters

window | the Meta.Window to activate |
time | (optional) current event time |
workspaceNum | (optional) window's workspace number |

### initializeDeferredWork ()

    string
    initializeDeferredWork (Clutter.Actor   actor,
                            function        callback);

This function sets up a callback to be invoked when either the given actor is mapped, or after some period of time when the machine is idle. This is useful if your actor isn't always visible on the screen (for example, all actors in the overview), and you don't want to consume resources updating if the actor isn't actually going to be displaying to the user.

Note that queueDeferredWork is called by default immediately on initialization as well, under the assumption that new actors will need it.

#### Parameters

actor | A `ClutterActor` |
callback | Function to invoke to perform work |

#### Returns

A string work identifer

### queueDeferredWork ()

    queueDeferredWork (string   workId);

Ensure that the work identified by `workId` will be run on map or timeout. You should call this function for example when data being displayed by the actor has changed.

#### Parameters

workId | work identifier |

### isInteresting ()

    boolean
    isInteresting (Meta.Window   metaWindow);

Determines whether a window is "interesting", i.e. ones to be displayed in alt-tab, window list etc.

#### Parameters

metaWindow | the window to be tested |

#### Returns

whether the window is interesting

### getTabList ()

    array
    getTabList (Meta.Workspace   workspaceOpt,
                Meta.Screen      screenOpt);

Return a list of the interesting windows on a workspace (by default, the active workspace). The list will include app-less dialogs.

#### Parameters

workspaceOpt | (optional) workspace, defaults to global.screen.get_active_workspace() |
screenOpt | (optional) screen, defaults to global.screen |

#### Returns

list of windows
