Member Function Documentation

createRasterizer()

virtual std::unique_ptr< Rasterizer > openmsx::VideoSystem::createRasterizer ( VDP &  vdp )

pure virtual

Create the rasterizer selected by the current renderer setting.

Video systems that use a rasterizer must override this method.

Parameters

vdp	The VDP whose display will be rendered.

Returns

The rasterizer created.

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

createV9990Rasterizer()

virtual std::unique_ptr< V9990Rasterizer > openmsx::VideoSystem::createV9990Rasterizer ( V9990 &  vdp )

pure virtual

Create the V9990 rasterizer selected by the current renderer setting.

Video systems that use a rasterizer must override this method.

Parameters

vdp	The V9990 whose display will be rendered.

Returns

The rasterizer created.

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

flush()

virtual void openmsx::VideoSystem::flush ( )

pure virtual

Finish pending drawing operations and make them visible to the user.

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

getClipboardText()

virtual std::string openmsx::VideoSystem::getClipboardText ( )

pure virtual

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

Referenced by openmsx::GetClipboardCommand::execute().

getCursorEnabled()

virtual bool openmsx::VideoSystem::getCursorEnabled ( )

pure virtual

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

getMouseCoord()

virtual gl::ivec2 openmsx::VideoSystem::getMouseCoord ( )

pure virtual

Returns the current mouse pointer coordinates.

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

getOutputSurface()

virtual OutputSurface * openmsx::VideoSystem::getOutputSurface ( )

pure virtual

TODO.

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

getWindowPosition()

virtual std::optional< gl::ivec2 > openmsx::VideoSystem::getWindowPosition ( )

pure virtual

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

repaint()

virtual void openmsx::VideoSystem::repaint ( )

pure virtual

Requests a repaint of the output surface.

An implementation might start a repaint directly, or trigger a queued rendering.

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

setClipboardText()

virtual void openmsx::VideoSystem::setClipboardText ( zstring_view  text )

pure virtual

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

Referenced by openmsx::SetClipboardCommand::execute().

setWindowPosition()

virtual void openmsx::VideoSystem::setWindowPosition ( gl::ivec2  pos )

pure virtual

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

showCursor()

virtual void openmsx::VideoSystem::showCursor ( bool  show )

pure virtual

Implemented in openmsx::DummyVideoSystem, and openmsx::SDLVideoSystem.

Referenced by openmsx::VisibleSurface::executeRT().

takeScreenShot()

void openmsx::VideoSystem::takeScreenShot ( const std::string &  filename, bool  withOsd  )

virtual

Take a screenshot.

The default implementation throws an exception.

Parameters

filename	Name of the file to save the screenshot to.
withOsd	Should OSD elements be included in the screenshot.

Exceptions

MSXException

If taking the screen shot fails.

Reimplemented in openmsx::SDLVideoSystem.

Definition at line 6 of file VideoSystem.cc.

updateWindowTitle()

void openmsx::VideoSystem::updateWindowTitle ( )

virtual

Called when the window title string has changed.

Reimplemented in openmsx::SDLVideoSystem.

Definition at line 13 of file VideoSystem.cc.
