std::unique_ptr< SDL_Window, SDLDestroyWindow > SDLWindowPtr
Represents the output window/screen of openMSX.
Definition Display.hh:32
Generic Gang-of-Four Observer class, templatized edition.
Definition Observer.hh:10
A frame buffer where pixels can be written to.
Video back-end system.
An OutputSurface which is visible to the user, such as a window or a full screen display.
void finish()
When a complete frame is finished, call this method.

std::unique_ptr< OutputSurface > createOffScreenSurface()
Create an off-screen OutputSurface which has similar properties as this VisibleSurface.
std::unique_ptr< Layer > createSnowLayer()
void saveScreenshot(const std::string &filename) override
Save the content of this OutputSurface to a PNG file.
std::optional< gl::ivec2 > getWindowPosition() const
Returns x,y coordinates of top-left window corner, or returns a nullopt when in fullscreen mode.
bool setFullScreen(bool fullscreen)
CliComm & getCliComm() const
int signalEvent(const Event &event) override
This method gets called when an event you are subscribed to occurs.
