debugger interface is implementing the IDebugger interface)
Your plugin can register to the following codelite events (look at
plugins.h):

wxEVT_DEBUG_STARTING - this one is sent when user initiates a debug
session. If you avoid calling event.Skip() in your handler - codelite will
assume that the plugin
is taking over the debug session and will not start the built-in gdb
debugger

There are other useful events that can be utilized to gain access to the
user shortcuts:
wxEVT_DEBUG_ENDED
wxEVT_DEBUG_STARTED
wxEVT_CMD_DEBUGGER_TIP - codelite is requesting a tooltip for the current
hovered variable
wxEVT_CMD_DEBUGGER_CAN_INTERACT - codelite needs to know whether the user
can interact with the debugger

To capture the debugger default commands (triggered either from the toolbar
/ menu), we need to add:

- wxEVT_DEBUGGER_NEXT
- wxEVT_DEBUGGER_STEPIN
- wxEVT_DEBUGGER_FINISH
- wxEVT_DEBUGGER_NEXT_INSTRUCTION
- wxEVT_DEBUGGER_STEP_OVER

Ofc, its up to the plugin to provide the UI and populate the proper values

To see how to write a plugin, just pick one of codelite's plugins
(Subversion is a plugin that accesses a lot of codelite UI )
Let me know if you need further assistance
