virtual void new_collector(int collector_index)
Called whenever a new Collector definition is received from the client.
virtual void clicked_label(int collector_index)
Called when the user single-clicks on a label.
void user_guide_bars_changed()
Called when the user guide bars have been changed.
virtual void new_data(int thread_index, int frame_number)
Called whenever new data arrives.
virtual void force_redraw()
Called when it is necessary to redraw the entire graph.
virtual void changed_graph_size(int graph_xsize, int graph_ysize)
Called when the user has resized the window, forcing a resize of the graph.
A window that contains a stack of labels from bottom to top.
This class represents a connection to a PStatsClient and manages the data exchange with the client.
This is our own Panda specialization on the default STL map.
