Methods
(protected) _activateCoreListeners(html)
Activate required listeners which must be enabled on every Application. These are internal interactions which should not be overridden by downstream subclasses.
Parameters:
Name | Type | Description |
---|---|---|
html |
jQuery |
(async, protected) _render(force, options) → {Promise.<void>}
An asynchronous inner function which handles the rendering of the Application
Parameters:
Name | Type | Default | Description |
---|---|---|---|
force |
boolean |
false
|
Render and display the application even if it is not currently displayed. |
options |
Object | New Application options which update the current values of the Application#options object |
Returns:
A Promise that resolves to the Application once rendering is complete
- Type
- Promise.<void>
activateListeners(html)
After rendering, activate event listeners which provide interactivity for the Application. This is where user-defined Application subclasses should attach their event-handling logic.
Parameters:
Name | Type | Description |
---|---|---|
html |
jQuery |
bringToTop()
Bring the application to the top of the rendering stack
(async) close() → {Promise.<void>}
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
Returns:
A Promise which resolves once the application is closed
- Type
- Promise.<void>
getData() → {Object|Promise}
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
Returns:
- Type
- Object | Promise
(async) maximize() → {Promise.<void>}
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
Returns:
A Promise which resolves once the maximization action has completed
- Type
- Promise.<void>
(async) minimize() → {Promise.<void>}
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
Returns:
A Promise which resolves once the minimization action has completed
- Type
- Promise.<void>
render(force, options) → {Application}
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
