performAction

performAction(actionName, params, capabilities, capabilitiesParams)

Performs an action on the server side. This method requests a new image from the client. Additional parameters are sent in the image request so that an action can be performed on the server side before the image is generated. This allows you to define a new type of interaction on the image. To implement the action on the server side, you must implement an action listener (ServerActionListener) on the server side. The action is defined by a name and a list of parameters.

Parameters:: actionName - The name of the action.; params - The parameters of the action as an array of strings.; capabilities - Indicates whether the action is affecting the capabilities (like the manager bounds or the layer list, for example) or not.; capabilitiesParams - The array that contains the parameter to pass to the getCapabilities method (if the capabilities parameter is set to true).

performJSFAction

performJSFAction(mb, params, capabilities, capabilitiesParams)

Performs a predefined action that will invoke the specified method binding.

This action will be executed before the image generation.
The signature of the method must be void methodName (IlvManagerView, String[]) where the first parameter is the IlvManagerView instance that renders the image and the second parameter is the array of action parameters. The action must only change the IlvManagerView instance as only the image is refreshed (the JSF components are not).

Parameters:: mb - The method binding to invoke.; params - The action parameters as a array of strings.; capabilities - Indicates whether the action is affecting the capabilities (like the manager bounds or the layer list, for example) or not.; capabilitiesParams - The array that contains the parameter to pass to the getCapabilities method (if the capabilities parameter is set to true).

Since:: JViews 8.0

Parameters:: backgroundColor - The background color to set.

setConstrainedOnContents

setConstrainedOnContents(constrainedOnContents)

Sets whether the view is constrained to the manager content bounds or not. The default value is true.
