The debuggee threads are displayed in the "Threads"
panel. The threads
command will also display the
threads of the debuggee.
JSwat has a notion of a "current" thread. That is, the
thread upon which various operations are performed. The current
thread is set automatically when the debuggee hits a breakpoint of
any kind. Otherwise, the current thread can be set manually using
the thread
command. It can also be set by clicking on
the thread in the "Threads" panel.
The current thread is indicated in the "Threads" panel
by drawing it with an italic font. The threads
command
uses the asterisk (*) character to indicate the current thread.
Any operations which require the current thread to be set will report an error message if the current thread has not been set.
The "Threads" panel has a popup menu which provides access to related functions and options. These menu items should be self-explanatory.
When the debuggee is suspended and the current thread is set,
the call stack is displayed in the "Stack" panel. The
stack can also be displayed using the where
command.
Whenever a breakpoint is hit, the current stack frame is set to
zero. The current frame is indicated by drawing it with an italic
font, and the frame can be changed by double-clicking on the
corresponding entry in the "Stack" panel. This has the
side-effect of opening the source file for the location given by
that frame. The current stack frame can also be changed using the
up
, down
, or frame
commands.
