Member Function Documentation

◆ add_menu()

const GtkStatsMonitor::MenuDef * GtkStatsMonitor::add_menu ( const MenuDef menu_def)

Adds a new MenuDef to the monitor, or returns an existing one if there is already one just like it.

Definition at line 328 of file gtkStatsMonitor.cxx.

References set_time_units().

Referenced by open_piano_roll().

◆ get_monitor_name()

string GtkStatsMonitor::get_monitor_name ( )
virtual

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

Implements PStatMonitor.

Definition at line 78 of file gtkStatsMonitor.cxx.

References initialized().

◆ get_window()

GtkWidget * GtkStatsMonitor::get_window ( ) const

Returns the window handle to the monitor's window.

Definition at line 286 of file gtkStatsMonitor.cxx.

References open_strip_chart().

Referenced by user_guide_bars_changed().

◆ got_bad_version()

void GtkStatsMonitor::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 122 of file gtkStatsMonitor.cxx.

References new_collector().

Referenced by got_hello().

◆ got_hello()

void GtkStatsMonitor::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 105 of file gtkStatsMonitor.cxx.

References got_bad_version().

Referenced by initialized().

◆ has_idle()

bool GtkStatsMonitor::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 262 of file gtkStatsMonitor.cxx.

References user_guide_bars_changed().

Referenced by idle().

◆ idle()

void GtkStatsMonitor::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 gtkStatsMonitor.cxx.

References PStatThreadData::get_frame_rate(), and has_idle().

Referenced by lost_connection().

◆ initialized()

void GtkStatsMonitor::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 94 of file gtkStatsMonitor.cxx.

References got_hello().

Referenced by get_monitor_name().

◆ lost_connection()

void GtkStatsMonitor::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 223 of file gtkStatsMonitor.cxx.

References idle().

Referenced by new_data().

◆ new_collector()

void GtkStatsMonitor::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 161 of file gtkStatsMonitor.cxx.

References GtkStatsGraph::new_collector(), and new_thread().

Referenced by got_bad_version().

◆ new_data()

void GtkStatsMonitor::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 205 of file gtkStatsMonitor.cxx.

References lost_connection(), and GtkStatsGraph::new_data().

Referenced by new_thread().

◆ new_thread()

void GtkStatsMonitor::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.

Referenced by new_collector().

◆ open_piano_roll()

void GtkStatsMonitor::open_piano_roll ( int  thread_index)

Opens a new piano roll showing the indicated data.

◆ open_strip_chart()

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

◆ set_pause()

void GtkStatsMonitor::set_pause ( bool  pause)

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

Definition at line 385 of file gtkStatsMonitor.cxx.

References PStatMonitor::close(), and GtkStatsGraph::set_pause().

Referenced by set_scroll_speed().

◆ set_scroll_speed()

void GtkStatsMonitor::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 367 of file gtkStatsMonitor.cxx.

Referenced by set_time_units().

◆ set_time_units()

void GtkStatsMonitor::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.
