++ \title Hello Vulkan Widget Example
++ \brief Shows the usage of QVulkanWindow in QWidget applications.
++ \examplecategory {Graphics}
++
++ The \e{Hello Vulkan Widget Example} is a variant of \l hellovulkantriangle
++ that embeds the QVulkanWindow into a QWidget-based user interface using
++ QWidget::createWindowContainer().
++
++ \image hellovulkanwidget.png {Screenshot of example with window showing image contents
++ and label showing color format and buttons to grab and quit}
++
++ The code to set up the Vulkan pipeline and render the triangle is the same
++ as in \l hellovulkantriangle. In addition, this example demonstrates
++ another feature of QVulkanWindow: reading the image content back from the
++ color buffer into a QImage. By clicking the Grab button, the example
++ renders the next frame and follows it up with a transfer operation in order
++ to get the swapchain color buffer content copied into host accessible
++ memory. The image is then saved to disk via QImage::save().
