Member Function Documentation

backingFormat()

QRhiTexture::Format QD3D11RenderBuffer::backingFormat ( ) const

overridevirtual

Implements QRhiRenderBuffer.

Definition at line 3191 of file qrhid3d11.cpp.

References QRhiRenderBuffer::m_backingFormatHint, QRhiRenderBuffer::m_type, QRhiTexture::RGBA8, and QRhiTexture::UnknownFormat.

create()

bool QD3D11RenderBuffer::create ( )

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.

Returns

true when successful, false when a graphics operation failed. Regardless of the return value, calling destroy() is always safe.

Implements QRhiRenderBuffer.

Here is the call graph for this function:

destroy()

void QD3D11RenderBuffer::destroy ( )

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.

Note

Resources referenced by commands for the current frame should not be released until the frame is submitted by QRhi::endFrame().

The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.
