Data-Sharing Techniques

Several of the techniques described in “Examples of Sharing Data Among a

GUI’s Callbacks” on page 9-10 for sharing data within a GUI can also share

data among several GUIs. You can use GUI data, application data, and

UserData property to communicate between GUIs as long as the handles

to objects in the first GUI are made available to other GUIs. This section

provides two examples that illus trate these techniques:

• “Exa mple — Manipulating a Modal Dialog Box fo r User Input” on page 9-22

This example describes how a simple GUI can open and receive data from

a modal dialog box.

• “Examp le — Individu al G UIDE GUIs Cooperating as Icon Manipulation

Tools” on page 9-30

This more extensive example illustrates how the three components of an

icon editor are made to interact.
