(params, cb)
clients/launcherClient.js, line 131

Gets monitorInfo (dimensions and position) for a given windowIdentifier or for a specific monitor. If neither the identifier or monitor are provided then the monitorInfo for the current window is returned.

The information returned contains a supplemented OpenFin monitor descriptor which contains:

monitorRect - The full dimensions for the monitor from OpenFin.

availableRect - The dimensions for the available space on the monitor (less windows toolbars).

unclaimedRect - The dimensions for available monitor space less any space claimed by components (such as the application Toolbar).

Each of these is supplemented with the following additional members:

width - The width as calculated (right - left).

height - The height as calculated (bottom - top).

position - The position of the monitor, numerically from zero to X. Primary monitor is zero.

whichMonitor - Contains the string "primary" if it is the primary monitor.

Name Type Description
params object optional


Name Type Description
windowIdentifier WindowIdentifier optional

The windowIdentifier to get the monitorInfo. If undefined, then the current window.

monitor number | string optional

If passed then a specific monitor is identified. Valid values are the same as for LauncherClient#spawn.

cb function optional

Returns a monitorInfo object containing the monitorRect, availableRect and unclaimedRect.

clients/launcherClient.js, line 152

Gets monitorInfo (dimensions and position) for all monitors. Returns an array of monitorInfo objects. See LauncherClient#getMonitorInfo for the format of a monitorInfo object.

Returns an array of monitorInfo objects.

clients/launcherClient.js, line 506

Returns a WindowIdentifier for the current window

Name Type Description
cb WindowIdentifier

Callback function returns windowIdentifier for this window (optional or use the returned Promise)

Type Description
Promise A promise that resolves to a windowIdentifier

clients/launcherClient.js, line 426

Returns an object that provides raw access to a remote window. It returns an object that contains references to the Finsemble windowDescriptor, to the OpenFin window, and to the native JavaScript (browser) window.

This will only work for windows that are launched using the Finsemble Launcher API.

As in any browser, you will not be able to manipulate a window that has been launched cross domain or in a separate physical OpenFin application (separate process). Caution should be taken to prevent a window from being closed by the user if you plan on referencing it directly. Due to these inherent limitations we strongly advise against a paradigm of directly manipulating remote windows through JavaScript. Instead leverage the RouterClient to communicate between windows and to use an event based paradigm!

  • Finsemble now uses a splintering agent which disconnects windows from the main launcher. It becomes impossible to access raw windows. See LauncherClient.getActiveDescriptors() and Util.getFinWindow()
    Name Type Description
    params object


    Name Type Description
    windowName string

    The name of the window to access.

    Type Description
    RawWindowResult An object containing windowDescriptor, finWindow, and browserWindow. Or null if window isn't found.

    (windowIdentifier, params, cb)
    clients/launcherClient.js, line 209

    Displays a window and relocates/resizes it according to the values contained in params.

    Name Type Description
    windowIdentifier WindowIdentifier

    A windowIdentifier.

    params object

    Parameters. These are the same as LauncherClient#spawn with the folowing exceptions:

    Name Type Default Description
    monitor any optional

    Same as spawn() except that null or undefined means the window should not be moved to a different monitor.

    left number | string optional

    Same as spawn() except that null or undefined means the window should not be moved from current horizontal location.

    top number | string optional

    Same as spawn() except that null or undefined means the window should not be moved from current vertical location.

    spawnIfNotFound boolean false optional

    If true, then spawns a new window if the requested one cannot be found. Note, only works if the windowIdentifier contains a componentType.

    slave boolean optional

    Cannot be set for an existing window. Will only go into effect if the window is spawned. (In other words, only use this in conjunction with spawnIfNotFound).

    cb function optional

    Callback to be invoked after function is completed. Callback contains an object with the following information: windowIdentifier - The WindowIdentifier for the new window. windowDescriptor - The WindowDescriptor of the new window. finWindow - An OpenFin window referencing the new window.

    (component, params, cb)
    clients/launcherClient.js, line 383

    Asks the Launcher service to spawn a new component. Any parameter below can also be specified in config/components.json, which will then operate as the default for that value.

    The launcher parameters mimic CSS window positioning. For instance, to set a full size window use left=0,top=0,right=0,bottom=0. This is functionally equivalent to: left=0,top=0,width="100%",height="100%"

    • 2.4.1 Added params.windowType (deprecated params.native), params.path, params.alias, params.argumentsAsQueryString - These are all for launching native apps.
    Name Type Description
    component String

    Type of the component to launch. If null or undefined, then params.url will be used instead.

    params object
    Name Type Default Description
    monitor number | string "mine" optional

    Which monitor to place the new window. "mine" - Place the window on the same monitor as the calling window. A numeric value of monitor (where primary is zero). "primary","next" and "previous" indicate a specific monitor. "all" - Put a copy of the component on all monitors

    position string unclaimed optional

    Defines a "viewport" for the spawn, with one of the following values:

    "unclaimed" (the default) Positioned based on the monitor space excluding space "claimed" by other components (such as toolbars). For instance, top:0 will place the new component directly below the toolbar.

    "available" Positioned according to the coordinates available on the monitor itself, less space claimed by the operating system (such as the windows toolbar). For instance, bottom:0 will place the new component with its bottom flush against the windows toolbar.

    "monitor" Positioned according to the absolute size of the monitor. For instance, top:0 will place the component overlapping the toolbar.

    "relative" Positioned relative to the relativeWindow. For instance, left:0;top:0 will join the top left corner of the new component with the top left corner of the relative window.

    "virtual" Positoned against coordinates on the virtual screen. The virtual screen is the full viewing area of all monitors combined into a single theoretical monitor.

    dockOnSpawn boolean false optional

    If true, will automatically dock the window with the "relative" window (dock to the parent window unless specified in params.relativeWindow).

    left number | string optional

    A pixel value representing the distance from the left edge of the viewport as defined by "position". A percentage value may also be used, representing the percentage distance from the left edge of the viewport relative to the viewport's width.

    "adjacent" will snap to the right edge of the spawning or relative window.

    "center" will center the window

    If neither left nor right are provided, then the default will be to stagger the window based on the last spawned window. Note - the staggering algorithm has a timing element that is optimized based on user testing.

    top number | string optional

    Same as left except related to the top of the viewport.

    right number | string optional

    Same as left except releated to the right of the viewport.

    bottom number | string optional

    Same as left except related to the bottom of the viewport.

    height number | string optional

    A pixel or percentage value.

    width number | string optional

    A pixel value or percentage value.

    forceOntoMonitor boolean optional

    If true will attempt to make the window no have parts outside the monitor boundary.

    ephemeral boolean false optional

    Indicates that this window is ephemeral. An ephemeral window is a dialog, menu or other window that is temporarily displayed but usually hidden. Ephemeral windows automatically have the following OpenFin settings assigned: resizable: false, showTaskbarIcon: false, alwaysOnTop: true. Note, use options:{autoShow: false} to prevent an ephemeral widow from showing automatically.

    staggerPixels number 100 optional

    Number of pixels to stagger (default when neither left, right, top or bottom are set).

    claimMonitorSpace boolean optional

    For use with permanent toolbars. The available space for other components will be reduced by the amount of space covered by the newly spawned component. This will be reflected in the unclaimedRect member from API calls that return monitorInfo. Users will be prevented from moving windows to a position that covers the claimed space. See position: 'unclaimed'.

    relativeWindow WindowIdentifier current window optional

    The window to use when calculating any relative launches. If not set then the window from which spawn() was called.

    slave boolean optional

    If true then the new window will act as a slave to the relativeWindow (or the launching window if relativeWindow is not specified). Slave windows will automatically close when their parent windows close.

    url string optional

    Optional url to launch. Overrides what is passed in "component".

    native string optional

    @deprecated Please use windowType instead. Optional native application to launch with Assimilation service. Overrides what is passed in "component".

    windowType string openfin optional

    Optional. Describes which type of component to spawn.

    openfin - A normal OpenFin HTML window.

    assimilation - A window that is managed by the Finsemble assimilation process (usually a native window without source code access). Requires "path" to be specified.

    native - A native window that has implemented finsemble.dll. Requires "path" to be specified. For more information.

    application - A standalone application. This launch a component in its own browser process (splintered, giving it dedicated CPU and memory). This can also point to a standalone OpenFin application (such as from a third party). For more information on integrating Openfin apps.

    alias string optional

    Used when windowType is "native" or "assimilation". Specifies the alias of an OpenFin bundled asset.

    path string optional

    Used when windowType is "native" or "assimilation". Specifies the path to the application. The path can be: The name of an exe that is on the system path (i.e. notepad.exe). The full path to an executable on the user's machine (i.e. C:\Program Files\app.exe) A system installed uri (i.e. myuri://myapp).

    When windowType is "native" then additional arguments will be automatically appended to the path or the uri. These arguments can be captured by the native application in order to tie it to Finsemble's window tracking. When building an application with finsemble.dll, this is handled automatically. Those arguments are:

    uuid - A generated UUID that uniquely identifies this window.

    left - The x coordinate of the new window

    top - The y coordinate of the new window

    width - The width of the new window

    height - The height of the new window

    openfinVersion - The openfin version that Finsemble runs (necessary for native windows to connection on the OpenFin IAB)

    openfinSocketPort - The openfin socket used for the IAB (necessary for Java windows that wish to use the OpenFin IAB)

    finsembleWindowName - The name of the window in the Finsemble config

    componentType - The component type in the Finsemble config

    A common troublesome problem is when a native application needs to be launched from an intermediary application (such as a launcher or batch script). That intermediary application can pass these parameters which will allow the final application to connect back to Finsemble.

    arguments string optional

    Used when windowType is "native" or "assimilation". Specifies the arguments to be sent to the application. This is used in conjunction with path. Arguments should be separated by spaces. Note that when params.argumentsAsQueryString is true, arguments should be a single string in uri format (i.e. a=1&b=2)

    argumentsAsQueryString boolean optional

    For native applications launched by URI, the automatic arguments assigned by path are converted into a query string.

    env any optional

    Sets environment variables for a spawned native application. Create a map (JSON) object of names to values. This is only available when running assimilation and with the config assimilation.useOpenFinSpawn=false.

    name string optional

    Optional window name. If not provided, then a random name will be assigned to the newly created OpenFin window.

    groupName string optional

    Optional group name. Adds windows to a group (unrelated to docking or linking) that is used for window management functions. If the group does not exist it will be created.

    data any optional

    Optional data to pass to the opening window. If set, then the spawned window can use WindowClient#getSpawnData to retrieve the data.

    options WindowDescriptor optional

    Properties to merge with the default windowDescriptor. Any value set here will be sent directly to the OpenFin window, and will override the effect of relevant parameters to spawn(). See for the full set and defaults, with the following exception:

    Name Type Default Description
    frame boolean false optional

    By default, all Finsemble windows are frameless

    addToWorkspace boolean false optional

    Whether to add the new component to the workspace. Even when true, the window will still not be added to the workspace if addToWorkspace==false in components.json config for the component type.

    cb function optional

    Callback to be invoked after function is completed. Callback contains an object with the following information: windowIdentifier - The {@WindowIdentifier} for the new component. windowDescriptor - The {@WindowDescriptor} for the new window. finWindow - An OpenFin window object that contains the spawned component.

    (element, windowIdentifier, params)
    clients/launcherClient.js, line 168

    A convenience method for dealing with a common use-case, which is toggling the appearance and disappearance of a child window when a button is pressed, aka drop down menus. Simply call this method from the click handler for your element. Your child window will need to close itself on blur events.

    Name Type Description
    element HTMLElement | selector

    The DOM element, or selector, clicked by the end user

    windowIdentifier windowIdentifier

    Identifies the child window

    params object

    Parameters to be passed to LauncherClient#showWindow if the child window is allowed to open
