Field Detail

toggleNode

public static E4Method toggleNode

Defines the method for toggling a node, means open and close a node.

See Also:

toggleNode(HTML html, E4CgiParams p)

activateNode

public static E4Method activateNode

Defines the method for activating (selecting) a node.

public E4ModuleBlockMenuHandling()

Method Detail

toggleNode

public void toggleNode(HTML html,
                       E4CgiParams p)

Change the open (display) mode of a tree node (E4TreeNode_Intf). If a user clicks on the [+] or [-] symbol beside a tree node, this changes the E4TreeNode_Intf.isOpen() state of the node. The whole tree needs to be stored in the session objects (see E4ServletImplementation_Intf.getSessionObject(String)). Parameters used to handle tree functionality: the tree-object handle E4ModuleTreeHandling._PARAM_TREE_OBJ and the node-id (e4s.application.sysmodule.moduleTreeHandlinge4s.application.sysmodule.E4ModuleTreeHandling#_PARAM_NODE_ID) as well as the target frame (E4ModuleTreeHandling._PARAM_TARGET).

Parameters:

html - the active HTML context to be used for output.

p - parameters, including the tree-object handle, node-id and target frame.

See Also:

activateNode

activateNode

public void activateNode(HTML html,
                         E4CgiParams p)

Change the activate (selected) state of a tree node as well as of all other nodes. (See E4TreeNode_Intf). If a user clicks on the node text or associated images, this changes the E4TreeNode_Intf.isActive() state of the selected node to true but all other nodes to false. The whole tree needs to be stored in the session objects (see E4ServletImplementation_Intf.getSessionObject(String)).

Parameters:

html - the active HTML context to be used for output.

p - parameters, including the tree-object handle E4ModuleTreeHandling._PARAM_TREE_OBJ and the node-id (E4ModuleTreeHandling._PARAM_NODE_ID) as well as the target frame (E4ModuleTreeHandling._PARAM_TARGET).
