Member Function Documentation

◆ addNode()

boolean de.yaacc.upnp.server.configuration.TreeNodeManager.addNode ( TreeNode node )

Add new node to the current tree nodes.

Parameters

node	to add it to the current tree nodes

Returns: true of this node is added

◆ collapse()

Change de.yaacc.upnp.server.configuration.TreeNodeManager.collapse ( TreeNode node )

Collapses the node: its children and the visible descendants of its expanded children leave the visible list.

Descendants keep their own expanded state, so expanding the node again restores them.

Returns: the removed rows (count 0 if the node is not visible or not expanded)

Referenced by de.yaacc.upnp.server.configuration.TreeNodeManager.collapseNode(), and de.yaacc.upnp.server.configuration.TreeViewAdapter.collapseNode().

Here is the caller graph for this function:

◆ collapseNode()

int de.yaacc.upnp.server.configuration.TreeNodeManager.collapseNode ( TreeNode node )

Collapsing node and all of his children.

Parameters

node	The node to collapse it

Returns: the index of this node if it exists in the list

Here is the call graph for this function:

◆ collapseNodeBranch()

int de.yaacc.upnp.server.configuration.TreeNodeManager.collapseNodeBranch ( TreeNode node )

Parameters

node	The node to collapse the branch of it

◆ expand()

Change de.yaacc.upnp.server.configuration.TreeNodeManager.expand ( TreeNode node )
