So far, most of the chapters in this book have concentrated on specific widgets. This chapter covers the methods that apply to all widgets. You'll probably never need most of these methods, but there are a few that you'll use frequently.
Many times, you'll use a MainWindow reference (usually $mwin our examples) to call these methods, but you can also call them from other widgets, such as $button, $checkbutton, and so on. Most of the methods are informational only, meaning you pass no arguments to them; you only get a value back.
We'll use the generic $widget here instead of a specific widget type. This will help you to remember that these are multipurpose methods.
