overridevirtual |
Creates the corresponding native graphics resources.
If there are already resources present due to an earlier create() with no corresponding destroy(), then destroy() is called implicitly first.
true
when successful, false
when a graphics operation failed. Regardless of the return value, calling destroy() is always safe. Implements QRhiRenderBuffer.

overridevirtual |
Releases (or requests deferred releasing of) the underlying native graphics resources.
Safe to call multiple times, subsequent invocations will be a no-op then.
Once destroy() is called, the QRhiResource instance can be reused, by calling create()
again. That will then result in creating new native graphics resources underneath.
The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.
