The AddLayer method dynamically adds a layer to a screen object at runtime.

The CloseScreen method closes a screen.

The Equals method determines whether the specified object is equal to the current object.

The GetAllScreenControls method retrieves all objects on a screen allowing programmatic interaction with all controls on a screen.

The GetGlobalDictionary method returns the dictionary itself, allowing a script writer to manipulate the dictionary directly or inspect its contents.

Example

The Canvas.Shared class, "CanvasGlobalDictionary," is a C# System.Collections.Generic.Dictionary<string, object>. The string represents the key and the object represents the value. This collection allows you to store any data you want and reference it later by the key assigned when it was added. If the same key is used multiple times, the original value would be replaced by the latest update.

See Global Dictionary for more information about using this method.

The GetHashCode method returns a hash code for the current object.

The GetType method returns the runtime type of the current instance.

The HideLayer method dynamically hides a layer on a screen object at runtime.

Hyperlinking in Canvas allows you to open another Canvas screen via script from the screen you are currently viewing. This is accomplished via script using the Hyperlink method on the sending (hyperlinking) screen and the OpenedViaHyperlink event on the receiving (hyperlinked) screen. Hyperlinking is supported between screens, objects, and nested views in Canvas, Canvas View, and Canvas View Lite.

See Hyperlinking Screens for more information about using this method.

The IsOrderInTypeConfiguredForDefinition method checks to see if an order in type (facility ordinal) is configured for the selected relative facility definition.

The IsScreenOpen method checks to see if a screen is open in that instance of Canvas or Canvas View. This method is case-insensitive.

The NavigateToScreenByFacility method is included on the screen object and allows you to navigate to a specific screen by selecting a CygNet facility.

Example

The script call is as follows:

The correlation between a facility and its associated screen is done via a facility attribute. You will need to configure the facility attribute that references the associated screen in your CygNet system for each facility using CygNet Explorer.

See Navigation by Facility for more information about using this method.

The ReadFromGlobalDictionary method reads a complex script object from another screen.

See Global Dictionary for more information about using this method.

The ResolveRelativeFacility method returns the resolved relative facility.

The SendFacilityBroadcast method broadcasts a facility to any open screen set to receive the facility.

See Broadcast a Message Via Script for more information about using this method.

The SendMessageBroadcast method broadcasts a message to any open screen set to receive the broadcast.

See Broadcast a Message Via Script for more information about using this method.

The SendParentMessage method sends a message from a child screen to a parent screen.

See Broadcast a Message Via Script for more information about using this method.

The SendSiteServiceBroadcast method broadcasts a SiteService to any open screen set to receive the SiteService.

See Broadcast a Message Via Script for more information about using this method.

The SerializeObject method stores the object in memory so that it can be recreated when needed.

The ShowLayer method dynamically shows a layer on a screen object at runtime.

The ToString method returns a string that represents the current object.
