| 89 |
|

| 90 | \ingroup appearance
|
|---|
| 91 |
|
|---|
| 92 | The QStyle class is an abstract base class that encapsulates the
|
|---|
| 93 | look and feel of a GUI. QStyleFactory creates a QStyle object
|
|---|
| 94 | using the create() function and a key identifying the style. The
|
|---|
| 95 | styles are either built-in or dynamically loaded from a style
|
|---|
| 96 | plugin (see QStylePlugin).
|
|---|
| 97 |
|
|---|
| 98 | The valid keys can be retrieved using the keys()
|
|---|
| 99 | function. Typically they include "windows", "motif", "cde",
|
|---|
| 100 | "plastique" and "cleanlooks". Depending on the platform,
|
|---|
| 101 | "windowsxp", "windowsvista" and "macintosh" may be available.
|
|---|
| 102 | Note that keys are case insensitive.
