What does the underscore mean in: _("Undo")

Expand Post »

Okay, it's been a long time since I've programmed in C++! Languages change considerably in the last 5 years or so. In reviewing some source code I often see statements like this:

C++ Syntax (Toggle Plain Text)
      wxString label;
      if (name == wxT("Undo")) {
         label = _("Undo");
      wxString label;
      if (name == wxT("Undo")) {
         label = _("Undo");

obviously, I snipped out a lot of code.

My question is, what does the underscore mean in:

C++ Syntax (Toggle Plain Text)
_("Undo")
_("Undo")

OK, that might be enough for me to actually figure out what it is being used for here. I thought it might be some new C++ convention.

Thanks!
