When you set a breakpoint, a breakpoint event is triggered in breakpoint.c 
(look for breakpoint_create_event, breakpoint_delete_event, 
breakpoint_modify_event).

In gdbtk/generic/gdbtk-hooks.c, we configure an event handler for this, 
gdbtk_*_breakpoint (which are all located in 
gdb/gdbtk/generic/gdbtk-bp.c).

These call the Tcl procedure gdbtk_tcl_breakpoint, which creates a 
BreakpointEvent (gdbevent.it[hb]), which is distributed to all the 
GDBEventHandlers.

The SrcTextWins are GDBEventHandlers, and so SrcTextWin::breakpoint is 
called, which (eventually) sets the breakpoint.
