void MyFrame::OnUpdateButton(wxUpdateUIEvent& event) { wxControl* ctrl = event.GetEventObject(); int ctrlId = ctrl->GetId(); // perform some action based on the control Id }
void MyFrame::OnUpdateButton(wxUpdateUIEvent& event) { if (someCondition) event.Enable(); else event.Disable(); }In this example, we are using the wxUpdateUIEvent object to enable or disable a button based on some condition. This is a common use case for update events, where we want to dynamically change the state of a control based on some condition. Package library: wxWidgets
