• SURFACE_2D - creates a 2D surface with 32bpp RGBA backbuffer accessed with getSurface() method
• SURFACE_GL - creates a surface with OpenGL context
• SURFACE_NONE - creates a window without attached surface

if SURFACE_NONE is selected - following surfaces can be attached:

• EGL - createEGLSurface()
• Vulkan - createVulkanSurface(VkInstance, VkSurfaceKHR*)
• Metal - createMetalSurface()

• nGKeepOnBottom - keep the window below others

destroy() - destroy surface

activate() - activate surface ( eg. set gl context to desired window )

update() - render windows and process events

getSurface() -return backbuffer pointer

getWidth() - return surface width

getHeight() - return surface height

setFocus() - focus window

valid() - return true if surface isn't destroyed

setWindowTitle(name) - set new window title

setMouseCapture(state) - enable/disable mouse capture

move(x,y) - move window to x,y

setIcon(data,width, height) - set app icon

toClipboard(const std::string& data) - copy data to clipboard
