[cdt-dev] displaying instructions and instructions histories in Eclipse: support needed in handling UI events and issue a gdb command


currently I am extending the cdt-dsf to implement the gdb commands for handling instructions and functions call histories, and parsing and getting their outputs.

I added two buttons and two basic views (see orange indications in following picture). and I can successfully display the instructions and functions calls histories when the user clicks on the buttons in the menu bar.

now I would like to add actions so that when the user clicks on a line in the function call history list,  a command is issued to gdb, get executed, and then the editor goes to the related line in the source code (similar to what happens when the user selects a stack frame in the debug view, or when the program halts in a breakpoint)

I added a class: public class FunctionsCallHistoryView extends AbstractDebugView implements IViewerUpdateListener, IDebugContextListener, IModelChangedListener

and registered a DoubleClickListener, public void doubleClick(DoubleClickEvent event) where I am identifying the clicked line extracting the record number and calling

// execute record goto record command
GdbGoToRecordCommand cmd = new GdbGoToRecordCommand(fFunctionsCallHistoryModel.getSession());


cmd.execute(null);  //how to prepare a IDebugCommandRequest request ?

I have two issues with this implementation:

- how to prepare a IDebugCommandRequest request object?

- Ideally this shall be executed asynchronously to the UI, is there a mean to achieve it?

On success, I would like a also to fire an event about the change done in the program counter so that the debug view and the source code refresh themself with the proper new PC, line of code and stack frame. is there any guidance/examples for achieving it?

can you please support me here?

Kind Regards
