29 /** @class FocusManager class
30 * @brief A central point for notifications about when wxTextCtrls get focus in the main window.
32 * This allows us to turn off accelerators for the duration of the focus so that they don't steal
33 * keypresses. It's a hack but the only way I could make it work on all platforms (looking for
34 * the focused thing and doing ev.Skip() if it's a wxTextCtrl did not work for me on Windows:
35 * ev.Skip() did not cause the event to be delivered).
40 /** emitted when any add()ed TextCtrl gets focus */
41 boost::signals2::signal<void ()> SetFocus;
42 /** emitted when any add()ed TextCtrl loses focus */
43 boost::signals2::signal<void ()> KillFocus;
45 void add(wxTextCtrl* c);
47 static FocusManager* instance();
50 void set_focus(wxFocusEvent &);
51 void kill_focus(wxFocusEvent &);
53 static FocusManager* _instance;
