Here is the call graph for this function:

onSimulatorBusy()

void ConsoleWindow::onSimulatorBusy ( SimulatorEvent &  event )

privatevirtual

An event handler for the event of the simulator to start processing a command.

The Console window must stay enabled when the simulator is busy, so this method is overloaded to not to lock the window.

Reimplemented from ProximSimulatorWindow.

Definition at line 281 of file ConsoleWindow.cc.

                                              {

}

onSimulatorDone()

void ConsoleWindow::onSimulatorDone ( SimulatorEvent &  event )

privatevirtual

An event handler for the event of the simulator to complete command processing.

The Console window is not locked during simulator processing, so there's no need to do anything.

Reimplemented from ProximSimulatorWindow.

Definition at line 293 of file ConsoleWindow.cc.

}

onSimulatorOutput()

void ConsoleWindow::onSimulatorOutput ( const SimulatorEvent &  event )

private

Handles simulator text output events.

The event data contains the simulator interpreter output, which is appended to the text output widget.

Parameters

event

Simulator interpreter text output event.
