[cdt-debug-dev] How to input a string as arg of MI command?

["Felix Yuan" <bigbrain_cn@xxxxxxx>]

Hi,

The MI interface of My debugger is similar to the one of gdb, so I can use
my debugger to replace gdb.

But there are something different. One is that my -exec-run has a argument.
So I want to use an InputDialog to get a string from user. I noticed that
when Target.restart() was called, a MIExecRun was created and posted to
MISession. I inserted some code to get a string via an InputDialog before
the command was created.
The source is:

try {
    Shell shell = new Shell();
    InputDialog dialog = new InputDialog(shell, "Label Dialog:", "Enter the
Label to start", null, null);
    dialog.open();
    String startLabel = dialog.getValue();
}
catch(Exception e){
    e.printStackTrace();
}

But when I ran Run-time Workbench, the following error was displayed:
Exception occurred during launch
Reason:
 Error within Debug UI:

I set a breakpoint before my code, but it seemed that it was not encountered
before the error occurred.

Please tell me how to use InputDialog in cdt.debug. Or is there another good
way to get a string from user when debugging?

Thanks in advance.

Sincerely yours,

Felix
