inlineprotectedvirtual

Reimplemented in VncServer.

Definition at line 197 of file vncinput.hh.

Referenced by setDirty().

◆ setDirty()

void VncInput::setDirty ( )

The frame buffer uses this call to notify the vnc server that the frame buffer has been updated and a new image needs to be sent to the client.

Reimplemented in VncServer.

Definition at line 92 of file vncinput.cc.

References _videoHeight, _videoWidth, captureEnabled, captureFrameBuffer(), DPRINTF, fb, frameBufferResized(), FrameBuffer::height(), ArmISA::width, and FrameBuffer::width().
