Hello Vulkan Widget Example

Shows the usage of QVulkanWindow in QWidget applications.

The Hello Vulkan Widget Example is a variant of hellovulkantriangle that embeds the QVulkanWindow into a QWidget -based user interface using createWindowContainer() .

The code to set up the Vulkan pipeline and render the triangle is the same as in 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 save() .
