The options provided to this application upon initialization
The application ID is a unique incrementing integer which is used to identify every application window drawn by the VTT
An internal reference to the HTML element this application renders
Track the current position and dimensions of the Application UI
DragDrop workflow handlers which are active for this Application
Tab navigation handlers which are active for this Application
SearchFilter handlers which are active for this Application
Track whether the Application is currently minimized
Track the most recent scroll positions for any vertically scrolling containers
The current render state of the Application
The prior render state of this Application. This allows for rendering logic to understand if the application is being rendered for the first time.
The sequence of rendering states that track the Application life-cycle.
Return the CSS application ID which uniquely references this UI element
Return the active application element, if it currently exists in the DOM
The path to the HTML template file which should be used to render the inner content of the app
Control the rendering style of the application. If popOut is true, the application is rendered in its own wrapper window, otherwise only the inner app content is rendered
Return a flag for whether the Application instance is currently rendered
An Application window should define its own title definition logic which may be dynamic depending on its data
Assign the default options configuration which is used by this Application class. The options and values defined in this object are merged with any provided option values which are passed to the constructor upon initialization. Application subclasses may include additional options which are specific to their usage.
An application should define the data object used to render its template. This function may either return an Object directly, or a Promise which resolves to an Object If undefined, the default implementation will return an empty object allowing only for rendering of static HTML
Render the Application by evaluating it's HTML template against the object of data provided by the getData method If the Application is rendered as a pop-out window, wrap the contained HTML in an outer frame with window controls
Add the rendered application to the DOM if it is not already present. If false, the Application will only be re-rendered if it is already present.
Additional rendering options which are applied to customize the way that the Application is rendered in the DOM.
The rendered Application instance
After rendering, activate event listeners which provide interactivity for the Application. This is where user-defined Application subclasses should attach their event-handling logic.
Change the currently active tab
The target tab name to switch to
Options which configure changing the tab
A specific named tab group, useful if multiple sets of tabs are present
Whether to trigger tab-change callback functions
Bring the application to the top of the rendering stack
Close the application and un-register references to it within UI mappings This function returns a Promise which resolves once the window closing animation concludes
A Promise which resolves once the application is closed
Minimize the pop-out window, collapsing it to a small tab Take no action for applications which are not of the pop-out variety or apps which are already minimized
A Promise which resolves once the minimization action has completed
Maximize the pop-out window, expanding it to its original size Take no action for applications which are not of the pop-out variety or are already maximized
A Promise which resolves once the maximization action has completed
Set the application position and store its new location. Returns the updated position object for the application containing the new values.
Positional data
The left offset position in pixels
The top offset position in pixels
The application width in pixels
The application height in pixels
The application scale as a numeric factor where 1.0 is default
|void}
An asynchronous inner function which handles the rendering of the Application
Render and display the application even if it is not currently displayed.
Additional options which update the current values of the Application#options object
A Promise that resolves to the Application once rendering is complete
Persist the scroll positions of containers within the app before re-rendering the content
The HTML object being traversed
Restore the scroll positions of containers within the app after re-rendering the content
The HTML object being traversed
Render the outer application wrapper
A promise resolving to the constructed jQuery object
Activate required listeners which must be enabled on every Application. These are internal interactions which should not be overridden by downstream subclasses.
Handle changes to the active tab in a configured Tabs controller
A left click event
The Tabs controller
The new active tab name
Handle changes to search filtering controllers which are bound to the Application
The key-up event from keyboard input
The raw string input to the search field
The regular expression to test against
The HTML element which should be filtered
Define whether a user is able to begin a dragstart workflow for a given drag selector
The candidate HTML selector for dragging
Can the current user drag this selector?
Define whether a user is able to conclude a drag-and-drop workflow for a given drop selector
The candidate HTML selector for the drop target
Can the current user drop on this selector?
Callback actions which occur at the beginning of a drag start workflow.
The originating DragEvent
Callback actions which occur when a dragged element is over a drop target.
The originating DragEvent
Callback actions which occur when a dragged element is dropped on a target.
The originating DragEvent
Create drag-and-drop workflow handlers for this Application
An array of DragDrop handlers
Create tabbed navigation handlers for this Application
An array of Tabs handlers
Create search filter handlers for this Application
An array of SearchFilter handlers
Render the inner application content
The data used to render the inner template
A promise resolving to the constructed jQuery object
Customize how inner HTML is replaced when the application is refreshed
The original HTML processed as a jQuery object
New updated HTML as a jQuery object
Customize how a new HTML Application is added and first appears in the DOM
The HTML element which is ready to be added to the DOM
Specify the set of config buttons which should appear in the Application header. Buttons should be returned as an Array of objects. The header buttons which are added to the application can be modified by the getApplicationHeaderButtons hook.
Create a ContextMenu for this Application.
The Application's HTML.
Handle application minimization behavior - collapsing content and reducing the size of the header
Additional actions to take when the application window is resized
Return the inheritance chain for this Application class up to (and including) it's base Application class.
The standard application window that is rendered for a large variety of UI elements in Foundry VTT.
Configuration options which control how the application is rendered. Application subclasses may add additional supported options, but these base configurations are supported for all Applications. The values passed to the constructor are combined with the defaultOptions defined at the class level.
