Detailed Description

Inherits from QApplication so that it can filter out XEvents during slow renders. Is the QApplication for the application.

Constructor & Destructor Documentation

SpikeStreamApplication::SpikeStreamApplication (  int  argc, char **  argv )

Constructor. Definition at line 34 of file SpikeStreamApplication.cpp. References renderDuration_ms, rendering, and startRenderKeyEventTime.

SpikeStreamApplication::~SpikeStreamApplication (   )

Destructor. Definition at line 42 of file SpikeStreamApplication.cpp.

SpikeStreamApplication::SpikeStreamApplication (  const SpikeStreamApplication &   )  [private]

Declare copy constructor private so it cannot be used inadvertently.

Member Function Documentation

SpikeStreamApplication SpikeStreamApplication::operator= (  const SpikeStreamApplication &   )  [private]

Declare assignment private so it cannot be used inadvertently.

bool SpikeStreamApplication::renderInProgress (   )

Returns true if the render is currently in progress. Definition at line 54 of file SpikeStreamApplication.cpp. References rendering.

void SpikeStreamApplication::startRender (   )

Called when the network viewer starts the render and records the time at this point and the time of the last key event. Definition at line 61 of file SpikeStreamApplication.cpp. References keyEventTime, rendering, startRenderKeyEventTime, and startRenderTime. Referenced by NetworkViewer::paintGL().

void SpikeStreamApplication::stopRender (   )

Records the time at which the render completes and calculates the duration of the render. Definition at line 70 of file SpikeStreamApplication.cpp. References renderDuration_ms, rendering, startRenderTime, and stopRenderTime. Referenced by NetworkViewer::paintGL().

bool SpikeStreamApplication::x11EventFilter (  XEvent *  xEvent  )  [protected]

Method inherited from QApplication that is called whenever an X11 XEvent is received by the application. Returning true filters the event, returning false passes the event on to the application. This method filters events that are received whilst the NetworkViewer is rendering. Since display lists are used, have no control during the render so have to look for events that were generated during the time window of the render. This method is specific to Linux. Definition at line 88 of file SpikeStreamApplication.cpp. References keyEventTime, renderDuration_ms, and startRenderKeyEventTime.
