Member Function Documentation

DECLARE_POPUP_MENU()

RateMenuTable::DECLARE_POPUP_MENU

(

RateMenuTable

)

IdOfRate()

int RateMenuTable::IdOfRate ( int  rate )

static

Converts a sampling rate to a wxWidgets menu item id.

Definition at line 368 of file WaveTrackControls.cpp.

{
   for (int i = 0; i<nRates; i++) {
      if (gRates[i] == rate)
         return i + OnRate8ID;
   }
   return OnRateOtherID;
}

References gRates, nRates, OnRate8ID, and OnRateOtherID.

InitUserData()

void RateMenuTable::InitUserData ( void *  pUserData )

overridevirtual

Called before the menu items are appended.

Store context data, if needed. May be called more than once before the menu opens. Pointer remains valid for the duration of any callback, if PopupMenuTable::BuildMenu() is called and the result's Popup() is called before any other menus are built.

Implements PopupMenuHandler.

{
   static RateMenuTable instance;

}

OnRateChange()

void RateMenuTable::OnRateChange

(
