Overview
This widget tutorial guides you through creating a small program that displays a selected image in a resizable window. This simple program illustrates some common concepts of widget programming, including:
- Designing a Simple Widget — how to define and arrange the widget elements you need
- Creating Event Handlers — how to communicate events to the widgets to perform the desired action
- State Structures — how to modify and save variable values when events happen
- Creating the Cleanup Procedure — how to clean up pointers when you close the program
Note
The program uses example data taken from magnetic resonance images (MRIs) of a human patient's thorax, head, and side view of the head and neck.
