## Detailed Description

This class represents a connection to a PStatsClient and manages the data exchange with the client.

Definition at line 38 of file winStatsMonitor.h.

## Constructor & Destructor Documentation

## ◆ WinStatsMonitor()

WinStatsMonitor::WinStatsMonitor | ( | WinStatsServer * | server | ) |

Definition at line 30 of file winStatsMonitor.cxx.

## ◆ ~WinStatsMonitor()

WinStatsMonitor::~WinStatsMonitor | ( |  | ) |
| virtual

Definition at line 45 of file winStatsMonitor.cxx.

## Member Function Documentation

## ◆ get_menu_id()

int WinStatsMonitor::get_menu_id | ( | const MenuDef & | menu_def | ) |

Returns the menu ID that is reserved for the indicated MenuDef properties.

If this is the first time these particular properties have been requested, a new menu ID is returned; otherwise, the existing menu ID is returned.

Definition at line 299 of file winStatsMonitor.cxx.

## ◆ get_monitor_name()

std::string WinStatsMonitor::get_monitor_name | ( |  | ) |
| virtual

Should be redefined to return a descriptive name for the type of PStatsMonitor this is.

Implements PStatMonitor.

Definition at line 74 of file winStatsMonitor.cxx.

## ◆ get_window()

HWND WinStatsMonitor::get_window | ( |  | ) | const

Returns the window handle to the monitor's window.

Definition at line 250 of file winStatsMonitor.cxx.

## ◆ got_bad_version()

void WinStatsMonitor::got_bad_version | ( | int | client_major,
|  | int | client_minor,
|  | int | server_major,
|  | int | server_minor )
| virtual

Like got_hello(), this is called when the "hello" message has been received from the client.

At this time, the client's hostname and program name will be known. However, the client appears to be an incompatible version and the connection will be terminated; the monitor should issue a message to that effect.

Reimplemented from PStatMonitor.

Definition at line 107 of file winStatsMonitor.cxx.

References PStatMonitor::get_client_hostname(), and PStatMonitor::get_client_progname().

## ◆ got_hello()

void WinStatsMonitor::got_hello | ( |  | ) |
| virtual

Called when the "hello" message has been received from the client.

At this time, the client's hostname and program name will be known.

Reimplemented from PStatMonitor.

Definition at line 94 of file winStatsMonitor.cxx.

References open_strip_chart().

## ◆ has_idle()

bool WinStatsMonitor::has_idle | ( |  | ) |
| virtual

Should be redefined to return true if you want to redefine idle() and expect it to be called.

Reimplemented from PStatMonitor.

Definition at line 230 of file winStatsMonitor.cxx.

## ◆ idle()

void WinStatsMonitor::idle | ( |  | ) |
| virtual

If has_idle() returns true, this will be called periodically to allow the monitor to update its display or whatever it needs to do.

Reimplemented from PStatMonitor.

Definition at line 201 of file winStatsMonitor.cxx.

References PStatMonitor::get_client_data(), PStatThreadData::get_frame_rate(), and PStatClientData::get_thread_data().

## ◆ initialized()

void WinStatsMonitor::initialized | ( |  | ) |
| virtual

Called after the monitor has been fully set up.

At this time, it will have a valid _client_data pointer, and things like is_alive() and close() will be meaningful. However, we may not yet know who we're connected to (is_client_known() may return false), and we may not know anything about the threads or collectors we're about to get data on.

Reimplemented from PStatMonitor.

Definition at line 86 of file winStatsMonitor.cxx.

## ◆ lookup_menu()

const WinStatsMonitor::MenuDef & WinStatsMonitor::lookup_menu | ( | int | menu_id | ) | const

Returns the MenuDef properties associated with the indicated menu ID.

This specifies what we expect to do when the given menu has been selected.

Definition at line 286 of file winStatsMonitor.cxx.

## ◆ lost_connection()

void WinStatsMonitor::lost_connection | ( |  | ) |
| virtual

Called whenever the connection to the client has been lost.

This is a permanent state change. The monitor should update its display to represent this, and may choose to close down automatically.

Reimplemented from PStatMonitor.

Definition at line 187 of file winStatsMonitor.cxx.

References PStatMonitor::get_client_hostname().

## ◆ new_collector()

void WinStatsMonitor::new_collector | ( | int | collector_index | ) |
| virtual

Called whenever a new Collector definition is received from the client.

Generally, the client will send all of its collectors over shortly after connecting, but there's no guarantee that they will all be received before the first frames are received. The monitor should be prepared to accept new Collector definitions midstream.

Reimplemented from PStatMonitor.

Definition at line 136 of file winStatsMonitor.cxx.

References WinStatsGraph::new_collector().

## ◆ new_data()

void WinStatsMonitor::new_data | ( | int | thread_index,
|  | int | frame_number )
| virtual

Called as each frame's data is made available.

There is no guarantee 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 PStatMonitor.

Definition at line 172 of file winStatsMonitor.cxx.

References WinStatsGraph::new_data().

## ◆ new_thread()

void WinStatsMonitor::new_thread | ( | int | thread_index | ) |
| virtual

Called whenever a new Thread definition is received from the client.

Generally, the client will send all of its threads over shortly after connecting, but there's no guarantee that they will all be received before the first frames are received. The monitor should be prepared to accept new Thread definitions midstream.

Reimplemented from PStatMonitor.

Definition at line 158 of file winStatsMonitor.cxx.

References WinStatsChartMenu::add_to_menu_bar().

## ◆ open_piano_roll()

void WinStatsMonitor::open_piano_roll | ( | int | thread_index | ) |

Opens a new piano roll showing the indicated data.

Definition at line 272 of file winStatsMonitor.cxx.

References WinStatsGraph::set_pause(), WinStatsGraph::set_scroll_speed(), and WinStatsPianoRoll::set_time_units().

## ◆ open_strip_chart()

void WinStatsMonitor::open_strip_chart | ( | int | thread_index,
|  | int | collector_index,
|  | bool | show_level )

Opens a new strip chart showing the indicated data.

Definition at line 258 of file winStatsMonitor.cxx.

References WinStatsGraph::set_pause(), WinStatsStripChart::set_scroll_speed(), and WinStatsStripChart::set_time_units().

Referenced by got_hello().

## ◆ set_pause()

void WinStatsMonitor::set_pause | ( | bool | pause | ) |

Called when the user selects a pause on or pause off option from the menu.

Definition at line 391 of file winStatsMonitor.cxx.

References WinStatsGraph::set_pause().

## ◆ set_scroll_speed()

void WinStatsMonitor::set_scroll_speed | ( | double | scroll_speed | ) |

Called when the user selects a new scroll speed from the monitor pulldown menu, this should adjust the speeds for all graphs to the indicated value.

Definition at line 350 of file winStatsMonitor.cxx.

References WinStatsGraph::set_scroll_speed().

## ◆ set_time_units()

void WinStatsMonitor::set_time_units | ( | int | unit_mask | ) |

Called when the user selects a new time units from the monitor pulldown menu, this should adjust the units for all graphs to the indicated mask if it is a time-based graph.

Definition at line 320 of file winStatsMonitor.cxx.
