Introducing the Web Component Framework 35

The User Interface

Data Types

Each property has a data type. By demanding that all data have an assigned type the Web

Component Framework can perform checks at design time to reduce the risk of

incompatible assignments.

Setting the Properties for a Label

Property: Label

The editor shows that the data type for this component is Any, which means that you

have complete freedom in assigning any type of data to this component. Of course, the

system must be able to convert whatever it is given to a visible string or the label won’t

be of much use.

You set the data type by clicking the Edit icon ( ) and choosing one of the available

types, which are listed in “Runtime Value Types” on page 131.

Some of the available runtime value types are:

• String

For the label component, the first choice is String. This is a simple type that

permits you to define a static string value for the label.

• Rich Text

The next choice is Rich Text that permits you to add HTML tags, so that you can

do some simple formatting, like italicizing a word.

• Context Selection

The next choice is context selection, and here there is a richer choice of options,

as shown in the dialog:

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 167 168
