Member Function Documentation

◆ destroy()

void QGles2SwapChainRenderTarget::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.

Implements QRhiResource.

Here is the caller graph for this function:

◆ devicePixelRatio()

float QGles2SwapChainRenderTarget::devicePixelRatio ( ) const

overridevirtual

Returns

the device pixel ratio. For QRhiTextureRenderTarget this is always

For targets retrieved from a QRhiSwapChain the value reflects the \l{QWindow::devicePixelRatio()}{device pixel ratio} of the targeted QWindow.

Implements QRhiRenderTarget.

◆ pixelSize()

QSize QGles2SwapChainRenderTarget::pixelSize ( ) const

overridevirtual

Returns: the size in pixels.

Valid only after create() has been called successfully. Until then the result is a default-constructed QSize.

With QRhiTextureRenderTarget the returned size is the size of the associated attachments at the time of create(), in practice the size of the first color attachment, or the depth/stencil buffer if there are no color attachments. If the associated textures or renderbuffers are resized and rebuilt afterwards, then pixelSize() performs an implicit call to create() in order to rebuild the underlying data structures. This implicit check is similar to what QRhiCommandBuffer::beginPass() does, and ensures that the returned size is always up-to-date.

Implements QRhiRenderTarget.
