Hi, I have an application that was heavily written on top of OpenGL. Right now I want to port it to Qt 6 with the minimum effort trying to stick to the OpenGL backend until I get the grip on the new things of Qt 6 Graphics API abstraction.
I used to do this in order to assign a target FBO to a QuickWindow: _quickWindow->setRenderTarget(_fboRender); This is no longer possible and it requires a QQuickRenderTarget to be created and I seem to have three options: (since 6.2) QQuickRenderTarget fromOpenGLRenderBuffer(uint renderbufferId, const QSize &pixelSize, int sampleCount = 1) (since 6.4) QQuickRenderTarget fromOpenGLTexture(uint textureId, uint format, const QSize &pixelSize, int sampleCount = 1) QQuickRenderTarget fromOpenGLTexture(uint textureId, const QSize &pixelSize, int sampleCount = 1) I’m trying this: _renderTarget = QQuickRenderTarget::fromOpenGLRenderBuffer(0, QSize(_renderResolution.width(), _renderResolution.height())); _quickWindow->setRenderTarget(_renderTarget); But nothing appears on the screen and I get a warning: QQuickWindow: No render target (neither swapchain nor custom target was provided) Can anyone tell me what am I failing here? Any ideas suggestions are very welcome.
