Member Function Documentation

◆ backingFormat()

QRhiTexture::Format QMetalRenderBuffer::backingFormat ( ) const

overridevirtual

Implements QRhiRenderBuffer.

Definition at line 3816 of file qrhimetal.mm.

◆ 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.

Definition at line 3754 of file qrhimetal.mm.

References d, destroy(), lastActiveFrameSlot, and samples.

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.
