Detailed Description

A gui_device that handles a set of windows.

Member Function Documentation

initialize_device()

virtual void tt::gui_device::initialize_device ( gui_window const & window )

virtual

Initialize the logical device.

Parameters

window

is used as prototype for queue allocation.

Reimplemented in tt::gui_device_vulkan.

score()

virtual int tt::gui_device::score ( gui_window const & window ) const

pure virtual

Check if this device is a good match for this window.

It is possible for a window to be created that is not presentable, in case of a headless-virtual-display, however in this case it may still be able to be displayed by any device.

Returns

-1 When not viable, 0 when not presentable, postive values for increasing score.

Implemented in tt::gui_device_vulkan.
