| 47 | The QGL class is a namespace for miscellaneous identifiers
|
|---|
| 48 | in the Qt OpenGL module.
|

|
|---|
| 50 | <p>
|
|---|
| 51 |
|
|---|
| 52 |
|
|---|
| 53 | <p> Normally you can ignore this class. <a href="qglwidget.html">QGLWidget</a> and the other
|
|---|
| 54 | OpenGL<sup>*</sup> module classes inherit it, so when you make your
|
|---|
| 55 | own QGLWidget subclass you can use the identifiers in the QGL
|
|---|
| 56 | namespace without qualification.
|
|---|
| 57 | <p> However, you may occasionally find yourself in situations where you
|
|---|
| 58 | need to refer to these identifiers from outside the QGL namespace's
|
|---|
| 59 | scope, e.g. in static functions. In such cases, simply write e.g. <a href="#FormatOption-enum">QGL::DoubleBuffer</a> instead of just <a href="#FormatOption-enum">DoubleBuffer</a>.
