Hallo, ich versuche, Mausbewegungen für eine MouseOver-Funktion in einer App zu erfassen, die mit Code :: Blocks mithilfe des wxSmith-Plugins erstellt wurde. Ich bin auf ein rätselhaftes Problem gestoßen. EVT_MOUSEWHEEL, das die Funktion in der EventTable aufruft, funktioniert gut, aber alle anderen Makros haben überhaupt kein Ergebnis. Und das Mausrad ist nichtJa wirklich will ich will (ich habe es nur zum Testen benutzt ...) Dies ist für Windows.

Hier ist ein grundlegender Problemcode (meistens generiert von derFantastisch wxSmith Plugin)

#include <wx/frame.h>
#include <wx/statusbr.h>

class MouseFrame: public wxFrame

    public:

        virtual ~MouseFrame();

        void OnQuit(wxCommandEvent& event);
        void OnAbout(wxCommandEvent& event);

MouseApp.h

#ifndef MOUSEAPP_H
#define MOUSEAPP_H

#include <wx/app.h>

class MouseApp : public wxApp
{
    public:
        virtual bool OnInit();

#endif // MOUSEAPP_H

Meine große Frage: Warum rufen EVT_MOTION, EVT_RIGHT_DOWN oder EVT_RIGHT_DCLICK MouseFrame :: MouseOver (wxMouseEvent & event) nicht so auf wie EVT_MOUSEWHEEL?
