 GtkStatsPianoRoll (GtkStatsMonitor *monitor, int thread_index)
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.
virtual void clicked_label (int collector_index)
 Called when the user single-clicks on a label.
virtual void force_redraw ()
 Called when it is necessary to redraw the entire graph.
virtual void new_data (int thread_index, int frame_number)
 Called as each frame's data is made available.
void set_horizontal_scale (double time_width)
 Changes the amount of time the width of the horizontal axis represents.
virtual void 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 the graph to the indicated mask if it is a time-based graph.

virtual void additional_graph_window_paint ()
 This is called during the servicing of expose_event; it gives a derived class opportunity to do some further painting into the graph window.
virtual void begin_draw ()
 Erases the chart area in preparation for drawing a bunch of bars.
void clear_region ()
 Erases the chart area.
virtual DragMode consider_drag_start (int graph_x, int graph_y)
 Based on the mouse position within the graph window, look for draggable things the mouse might be hovering over and return the appropriate DragMode enum or DM_none if nothing is indicated.
virtual void draw_bar (int row, int from_x, int to_x)
 Draws a single bar on the chart.
virtual void end_draw ()
 Called after all the bars have been drawn, this triggers a refresh event to draw it to the window.
virtual gboolean handle_button_press (GtkWidget *widget, int graph_x, int graph_y, bool double_click)
 Called when the mouse button is depressed within the graph window.
virtual gboolean handle_button_release (GtkWidget *widget, int graph_x, int graph_y)
 Called when the mouse button is released within the graph window.
virtual gboolean handle_motion (GtkWidget *widget, int graph_x, int graph_y)
 Called when the mouse is moved within the graph window.
virtual void idle ()
 Called at the end of the draw cycle.

Definition at line 195 of file gtkStatsPianoRoll.cxx.

References GtkStatsGraph::get_collector_gc().

void GtkStatsPianoRoll::end_draw ( ) [protected, virtual]
