event.Skip();

不处理事件让后续处理

点击button（事件）

触发函数（处理）

函数中调用event？？怎么理解

可以处理事件的类都继承自wxEvtHandler,其中包含frames, buttons, menus, even documents，所有的窗体类(即从wxWindow继承的类)和程序类(application class).

event.Skip();

void MyTextCtrl::OnChar(wxKeyEvent& event)

{   if ( isalpha( event.KeyCode() ) )

    {  // key code is within legal range. we call event.Skip() so the

       // event can be processed either in the base wxWidgets class

       // or the native control.

      event.Skip();   }   else

    {  // illegal key hit. we don't call event.Skip() so the

       // event is not processed anywhere else.

        wxBell();   }}
