Controladores de eventos que no reciben la llamada? - wxWidgets

Question

Estoy trabajando en un programa para mi clase de programación C++, usando wxWidgets. Tengo un gran problema porque mis manejadores de eventos (supongo) no están siendo llamados, porque cuando hago clic en el botón para desencadenar el evento, no pasa nada. Mi pregunta es: ¿me pueden ayudar a encontrar el problema y explicar por qué no los llamarán?

Los controladores de eventos OnAbout y OnQuit funcionan, pero no OnCompute u OnClear. Estoy muy frustrado ya que no puedo resolver esto. ¡Muchas gracias de antemano!

Answer 1

EVT_MENU (BUTTON_COMPUTE, MainPanel :: OnCompute) EVT_MENU (BUTTON_CLEAR, MainPanel :: su dudoso)

En las declaraciones anteriores EVT_BUTTON utilizar en lugar de EVT_MENU.

Answer 2

Creo que lo veo. En la tabla de eventos para MainPanel en lugar de EVT_MENU, use EVT_BUTTON.
