Member Function Documentation

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 352 of file winStatsMonitor.cxx.

Referenced by WinStatsChartMenu::do_update().

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 82 of file winStatsMonitor.cxx.

Returns the window handle to the monitor's window.

Definition at line 292 of file winStatsMonitor.cxx.

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 126 of file winStatsMonitor.cxx.

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

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 109 of file winStatsMonitor.cxx.

References open_strip_chart().

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 268 of file winStatsMonitor.cxx.

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 237 of file winStatsMonitor.cxx.

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

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 98 of file winStatsMonitor.cxx.

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 335 of file winStatsMonitor.cxx.

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 220 of file winStatsMonitor.cxx.

References PStatMonitor::get_client_hostname().

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 159 of file winStatsMonitor.cxx.

References WinStatsGraph::new_collector().

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 202 of file winStatsMonitor.cxx.

References WinStatsGraph::new_data().

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.

void WinStatsMonitor::open_piano_roll ( int  thread_index)

Opens a new piano roll showing the indicated data.

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

Opens a new strip chart showing the indicated data.

void WinStatsMonitor::set_pause ( bool  pause)

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

Definition at line 453 of file winStatsMonitor.cxx.

References WinStatsGraph::set_pause().

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 409 of file winStatsMonitor.cxx.

References WinStatsGraph::set_scroll_speed().

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 376 of file winStatsMonitor.cxx.

References WinStatsGraph::set_time_units().

Called when the user guide bars have been changed.
