Detailed Description
A window that draws a piano-roll style chart, which shows the collectors explicitly stopping and starting, one frame at a time.
Definition at line 31 of file winStatsPianoRoll.h.
Member Function Documentation
◆ changed_graph_size()
|
virtual |
Called when the user has resized the window, forcing a resize of the graph.
Reimplemented from WinStatsGraph.
Definition at line 78 of file winStatsPianoRoll.cxx.
◆ clicked_label()
|
virtual |
Called when the user single-clicks on a label.
Reimplemented from WinStatsGraph.
Definition at line 106 of file winStatsPianoRoll.cxx.
References WinStatsMonitor::open_strip_chart().
◆ force_redraw()
|
virtual |
Called when it is necessary to redraw the entire graph.
Reimplemented from WinStatsGraph.
Definition at line 70 of file winStatsPianoRoll.cxx.
◆ new_data()
|
virtual |
Called as each frame's data is made available.
There is no gurantee the frames will arrive in order, or that all of them will arrive at all. The monitor should be prepared to accept frames received out-of-order or missing.
Reimplemented from WinStatsGraph.
Definition at line 60 of file winStatsPianoRoll.cxx.
◆ set_horizontal_scale()
| void WinStatsPianoRoll::set_horizontal_scale | ( | double | time_width | ) |
Changes the amount of time the width of the horizontal axis represents.
This may force a redraw.
Definition at line 117 of file winStatsPianoRoll.cxx.
References PStatPianoRoll::set_horizontal_scale().
◆ set_time_units()
|
virtual |
Called when the user selects a new time units from the monitor pulldown menu, this should adjust the units for the graph to the indicated mask if it is a time-based graph.
Reimplemented from WinStatsGraph.
Definition at line 88 of file winStatsPianoRoll.cxx.
