|
|
|
|
Initializes the \a context and sets up the QGLWindowSurface of the
|
|
QWidget of \a context based on the parameters of \a context and
|
|
based on its own requirements. The format() of \a context needs
|
|
to be updated with the actual parameters of the OpenGLES drawable
|
|
that was set up.
|
|
|
|
\a shareContext is used in the same way as for QGLContext. It is
|
|
the context with which \a context shares display lists and texture
|
|
ids etc. The window surface must be set up so that this sharing
|
|
works.
|
|
|
|
Returns true in case of success and false if it is not possible to
|
|
create the necessary OpenGLES drawable/context.
|
|
|
|
Since 4.4.2, this function will be not be called if options()
|
|
indicates that a native window or pixmap drawable can be created
|
|
via the functions in the surfaceFunctions() object.
|
|
|
|
This function is obsolete in Qt 4.5 and higher. Use surfaceFunctions()
|
|
instead.
