Member Function Documentation

◆ backingFormat()

QRhiTexture::Format QMetalRenderBuffer::backingFormat ( ) const

overridevirtual

Implements QRhiRenderBuffer.

Definition at line 3657 of file qrhimetal.mm.

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

◆ create()

bool QMetalRenderBuffer::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 QMetalRenderBuffer::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.
