Detailed Description

A GUIDevice that handles a set of windows.

Member Function Documentation

◆ initializeDevice()

virtual void tt::GUIDevice_base::initializeDevice ( Window const & window )

virtual

Initialise the logical device.

Parameters

window is used as prototype for queue allocation.

Reimplemented in tt::GUIDevice_vulkan.

◆ score()

virtual int tt::GUIDevice_base::score ( 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::GUIDevice_vulkan.

Field Documentation

◆ windows

std::vector<std::unique_ptr<Window> > tt::GUIDevice_base::windows

A list of windows managed by this device.
