The wxCommandEvent GetEventObject function is a method of the wxWidgets library's wxCommandEvent class in C++ that returns the object associated with the event.
Example 1: In a GUI application, if a button is clicked, it generates an event that can be captured using an event handler. The GetEventObject() method can be used to retrieve the object that generated the event, which in this case would be the button that was clicked. Code example:
void MyFrame::OnButtonClick(wxCommandEvent& event) { wxButton* btn = dynamic_cast(event.GetEventObject()); if (btn) { // do something with the button } }
Example 2: Another example involves using the GetEventObject() function in a custom event class. Code example:
class MyCustomEvent : public wxCommandEvent { public: MyCustomEvent(wxEventType eventType, int id) : wxCommandEvent(eventType, id) {}
virtual wxEvent* Clone() const { return new MyCustomEvent(*this); }
// Somewhere in code where the event is being processed void MyEventProcessor::OnMyCustomEvent(MyCustomEvent& event) { wxObject* obj = event.GetEventObject(); // Get the object associated with the event if (obj) { // do something with the object } }
