Etkinlik İşleyicileri Çağrılmıyor mu? - wxWidgets

Question

WxWidgets kullanarak C++ programlama sınıfım için bir program üzerinde çalışıyorum. Olay işleyicimin (varsaydığımı) almamam için çok büyük bir sorun yaşıyorum çünkü olayı tetiklemek için düğmeye tıkladığımda hiçbir şey olmuyor. Sorum şu: Sorunu bulmama yardım edip neden çağırılmayacaklarını açıklayabilir misiniz?

OnAbout ve OnQuit olay işleyicileri çalışıyor, OnCompute veya OnClear'da değil. Bunu anlayamadığım için çok sinirliyim. Şimdiden bir demet teşekkürler!

Answer 1

EVT_MENU (BUTTON_COMPUTE, MainPanel :: OnCompute) EVT_MENU (BUTTON_CLEAR, MainPanel :: OnClear) Yukarıdaki tablolarda

yerine EVT_MENU arasında EVT_BUTTON kullanımı.

Answer 2

Sanırım onu ​​görüyorum. MainPanel etkinlik tablosunda EVT_MENU yerine EVT_BUTTON kullanın.
