Constructor Detail

Tree

function Tree(<boolean> multiSelect)

Creates a tree widget. Trees are basically just containers that only expect to have tree nodes appended to them as children. Appending other types of widgets will cause visual bugs.

Parameters:
multiSelect - a boolean indicating whether or not multiple nodes can be selected in the tree. Defaults to false, which implies single-selection behaviour.

blur

void blur()

expandTo

void expandTo(<int> depth)

Expands the tree's root nodes to depth depth. See TreeNode.expandTo() for how to set depth.

Parameters:
depth - the depth to which each of this tree's children should be expanded.

focus

void focus()

getSelection

AbstractList getSelection()

Returns an AbstractList containing the TreeNodes that are currently selected.

Returns:
the current selection as a list

setSelection

void setSelection(<WidgetList> selection)

Selects the TreeNodes in selection.

Parameters:
selection - a list containing TreeNodes to select
