Tree component 227
Event summary for the TextInput class
Tree component
The Tree component allows a user to view hierarchical data. The tree appears within a box like the
List component, but each item in a tree is called a node and can be either a leaf or a branch. By
default, a leaf is represented by a text label beside a file icon and a branch is represented by a text
label beside a folder icon with a disclosure triangle that a user can open to expose children. The
children of a branch can either be leaves or branches themselves.
The data of a tree component must be provided from an XML data source. For more
information, see the next section.
When a Tree instance has focus either from clicking or tabbing, you can use the following keys to
control it:
TextInput.maxChars
The maximum number of characters that a user can enter in a TextInput
text field.
TextInput.maxHPosition
The maximum possible value for TextField.hPosition. This property is
read-only.
TextInput.password
A Boolean value that indicates whether or not the input text field is a
password field that hides the entered characters.
TextInput.restrict
Indicates which characters a user can enter in a text field.
TextInput.text
