X11Screen() [2/4]

X11Screen ( Application &  app, const Size &  size = Size(800, 480), const std::string &  name = {}, bool  borderless = false  )

explicit

Parameters

app	Application instance this screen is associated with.
size	Size of the screen.
borderless	Create the X11 window without a border.

Member Function Documentation

copy_to_buffer()

void copy_to_buffer ( ScreenBuffer &  buffer )

overrideprotectedvirtual

Copy the framebuffer to the current composition buffer.

Reimplemented from Screen.

disable_window_decorations()

void disable_window_decorations

(

)

Disable window decorations.

flip()

void flip ( const DamageArray &  damage )

overridevirtual

Perform a flip of the buffers.

This iterates the buffers and puts the composition buffer into the screen buffers.

Note

This will call schedule_flip() automatically.

Reimplemented from Screen.

handle_read()

void handle_read ( const asio::error_code &  error )

protected

Callback for X11 server data.

operator=() [1/2]

X11Screen& operator= ( const X11Screen &  )

delete

operator=() [2/2]

X11Screen& operator= ( X11Screen &&  )

delete

schedule_flip()

void schedule_flip ( )

inlineoverridevirtual

Schedule a flip to occur later.

This is needed if a flip should occur sometime in the future to the hardware.

Implements Screen.
